DCI OpenShift Agent

dci-openshift-agent provides Red Hat OpenShift Container Platform (RHOCP) in Red Hat Distributed CI service.

There are some benefits of running the DCI OCP Agent:

Automation of nightly/dev preview/candidate/ga OCP component testing
CI runs on your own hardware
Red Hat doesn't have access to your hardware, the agent reports metrics/logs back to distributed-ci.io
The agent leverages the OpenShift IPI/UPI/AI/ACM/ZTP installers
You have access to all your jobs logs and metrics through distributed-ci.io where you can also set notifications for errors/exceptions

See the installer's documentation for details about the supported/required variables for each deployment method.

Requirements

Network requirements

This is a summary taken from the upstream Network requirements guide from OpenShift:

Each server needs 2 NICs pre-configured. NIC1 for the private/provisioning network and NIC2 for the baremetal network. NIC interface names must be identical across all nodes
Each server's NIC1 (provisioning) must be configured for PXE booting in BIOS/UEFI
Each server must have IPMI configured and functional
Each server must have static IP addresses for their baremetal NICs plus a dynamic pool of 5 or more IP addresses with a short TTL (2h) for the bootstrap VM
Must have 2 reserved virtual IPs for API (api.<cluster>.<domain>) and wildcard ingress (*.apps.<cluster>.<domain>) and DNS setup for both. Please follow the Openshift Baremetal DNS server configuration as a reference guide
Optional - Include DNS entries for the hostnames for each of the servers
Nightly builds require that the provisionhost (SNO or IPI installs) is able to communicate directly to the controller server.

Systems requirements

DCI OpenShift Agent needs a dedicated system to act as a controller node. It is identified as the DCI Jumpbox in this document. This system will be added to a standard OCP topology by being connected to the OCP baremetal network. The DCI OpenShift Agent will drive the RHOCP installation workflow from there.

Therefore, the simplest working setup must be composed of at least 5 systems (1 system for DCI and 4 systems to match OCP minimum requirements).

Please use the OpenShift Baremetal Deploy Guide (a.k.a. openshift-kni) as a reference for how to properly configure the OCP networks, systems and DNS.

Choose the OCP version you want to install and follow these steps to configure the networks and install RHEL 8 on the OpenShift Provisioning node.

Setting up access to DCI
Installation of DCI Jumpbox
Installation of Provision Host

As mentioned before, the DCI Jumpbox is NOT part of the RHOCP cluster. It is only dedicated to download RHOCP artifacts from DCI public infrastructure and to schedule the RHOCP cluster deployment across all systems under test (1x OpenShift Provisioning node and several OCP nodes).

The OpenShift Provisioning node is used by the OpenShift installer to provision the OpenShift cluster nodes.

The 3 remaining systems will run the freshly installed OCP Cluster. “3” is the minimum required number of nodes to run RHOCP but it can be more if you need to.

Jumpbox requirements

The Jumpbox can be a physical server or a virtual machine. In any case, it must:

Be running the latest stable RHEL release (8.4 or higher) and registered via RHSM.
Have at least 160GB of free space available in /var
Having full access to Internet is highly recommended
Be able to connect the following Web urls:
- DCI API: https://api.distributed-ci.io
- DCI Packages: https://packages.distributed-ci.io
- DCI Repository: https://repo.distributed-ci.io
- EPEL: https://dl.fedoraproject.org/pub/epel/
- Ansible Runner Repository: https://releases.ansible.com/ansible-runner/
- QUAY: https://quay.io
- Nightly releases: https://registry.ci.openshift.org
- RED HAT REGISTRY: https://registry.redhat.io
- RED HAT SSO: https://access.redhat.com
- RED HAT CATALOG: https://catalog.redhat.com
- OpenShift Mirrors: https://rhcos.mirror.openshift.com and https://mirror.openshift.com
- GitHub: https://github.com
- Software Factory (gerrit): https://softwarefactory-project.io
- Access to cloudfront CDN
Have a static internal (network lab) IP
Be able to reach all systems under test (SUT) using (mandatory, but not limited to):
- SSH
- IPMI
- Serial-Over-LAN or other remote consoles (details & software to be provided by the partner)
Be reachable by the Systems Under Test by using:
- DHCP
- PXE
- HTTP/HTTPS

NOTES:

Make sure rhel-8-for-x86_64-appstream-rpms repo provides access to libvirt => 6.0.0 packages
The installer may require access to other endpoint (CDNs). The list above is for well know URLs that be subject to change.

Systems under test

Systems under test will be installed through DCI workflow with each job and form the new “fresh” RHOCP cluster.

All files on these systems are NOT persistent between each dci-openshift-agent job as the RHOCP cluster is reinstalled at each time. Therefore, every expected customization and tests have to be automated from the DCI Jumpbox (by using hooks) and will therefore be applied after each deployment (More info at Jumpbox Configuration).

Optional DCI Access

We strongly advise the partners to provide the Red Hat DCI team with access to their jumpbox. This way, Red Hat engineers can help with initial setup and troubleshooting.
We suggest to run the full virtualized provided example first to understand how the dci-openshift-agent works before going to production with a real lab.

Setting up access to DCI

The DCI dashboard gives you a view into what jobs you have run in your distributed agent. In order to gain access to it you have to:

Go to https://www.distributed-ci.io/ and click login. You will be redirected to sso.redhat.com so you'll use your RH account credentials
If you are not part of any teams you can contact an admin to get yourself added
You will have to create a Remote CI for use later, go on the left navigation bar on the Remotecis option and click on "Create a new remoteci"
Fill out the description and which team it belongs to then click Create
You should see your newly created remoteci in the list, you can get the credentials in YAML format by click the button in the Authentication column. This should be saved under ~/.config/dci-pipeline/dci_credentials.yml.

Installation of DCI Jumpbox

Before proceeding you should have set up your networks and systems according to the baremetal-deploy doc that was referenced above.

Provision the Jumphost with RHEL8. This includes subscribing the host to RHSM and ensuring it's receiving updates.

The dci-openshift-agent is packaged and available as a RPM file. However,dci-release and epel-release along with additional support repos must be installed first:

For RHEL-8

subscription-manager repos --enable=rhel-8-for-x86_64-baseos-rpms
subscription-manager repos --enable=rhel-8-for-x86_64-appstream-rpms
subscription-manager repos --enable=ansible-2-for-rhel-8-x86_64-rpms

For CentOS Stream 8

dnf install centos-release-ansible-29.noarch

For Both

dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
dnf -y install https://packages.distributed-ci.io/dci-release.el8.noarch.rpm
dnf config-manager --add-repo=https://releases.ansible.com/ansible-runner/ansible-runner.el8.repo
dnf -y install dci-openshift-agent

Folders and files location

Once dci-openshift-agent package is installed, the files and resources you can find in this repository will be placed in the following locations:

/etc/dci-openshift-agent contains these folders and files: dcirc.sh.dist file, hooks folder, settings.yml file.
/usr/share/dci-openshift-agent/ gathers the following folders and files: action_plugins folder, ansible.cfg file, dci-openshift-agent.yml file, group_vars folder, plays folder, test-runner script and utils folder.
/var/lib/dci-openshift-agent folder holds the samples folder.

Also, have in mind that:

dci-openshift-agent user (with sudo permissions) and group are created

Installation of OCP Provision Host

The provision host is part of the OCP requirements, as such you should follow the guide linked before. The main things you need to know about the provision host are:

Provision with RHEL8
Subscribe to RHSM and make sure it is receiving updates
Install the EPEL RPM package
Must have 2 NICs: one for the baremetal public/routed network and another for the provisioning private network
Create a kni user
Create a ssh key for the kni user

Copying the ssh key to your provisioner

# su - dci-openshift-agent
% ssh-keygen
% ssh-copy-id kni@provisionhost

Collections

The dci-openshift-agent relies on redhatci.ocp ansible collections that provide a set of roles and plugins that bring the functionality to the agent. The ansible collections are installed as a dependency of the agent and the project is hosted in https://github.com/redhatci/ansible-collection-redhatci-ocp

Pipelines

To configure your DCI job pipelines, you need to install dci-pipeline. Instructions at dci-pipeline documentation.

Disconnected mode in DCI OCP agent

When using the agent in a disconnected environment, special variables should be used. See the disconnected doc for more details.

Pull secrets

Pull secrets are credentials used against container registries that require authentication.

DCI provide pull secrets used to deploy OCP on every job.

cloud.openshift.com - Insights monitoring
quay.io - Openshift releases
registry.ci.openshift.org - Nightly builds
registry.connect.redhat.com - Red Hat images
registry.redhat.io - Red Hat images

These pull secrets are used by default, but the agent allows using other pull secrets if needed through some variables.

openshift_secret: String with secrets that are appended to the job's provided pull secrets. Used to include additional credentials. This is an agent variable.
disconnected_registry_auths_file: A file with a string that contains the auths for private registries.
pullsecret_file: File with secrets in JSON format that will be used along with the ones provided by DCI job and the openshift_secret.

The content all these variables is merged by DCI, those secrets are combined in a single podman authentication file used to interact with the required registries during the mirroring, image inspections, pruning tasks performed byt the DCI Openshift agent.

Important:

Secrets are processed in the following order: Job secrets --> openshift_secret --> disconnected_auths --> pull_secret_file
If a registry entry exists in multiple sources, the last one processed takes priority
It is recommended that the additional secrets are set in the form of registryA/ to use an specific auth entry against a registry as recommended in the podman documentation

Disconnected environment

Another related variable is disconnected_registry_auths_files used in IPI or SNO installs.

This is an inventory variable used in disconnected environments. The content of this file is appended to the list of DCI provided pull secrets. This file is used for two main purposes.

To allow the cluster to communicate to a local registry
To use to mirror images to the local registry

Storing secrets

You can store secrets in an encrypted manner in your pipelines and YAML inventories by using dci-vault to generate your encrypted secrets. Details in the python-dciclient documentation.

Deploying operators

The Agent manages the mirroring and deployment of most of the day-2 operators. For others, it can configure them by setting up the corresponding operands.

The workflow for the deployment is:

Operator mirroring for disconnected environments
Operator installation
Operator configuration

Operators mirroring for disconnected environments

The opm_mirror_list variable, controls the operators that are mirrored when dci_disconnected is true. The Agent takes care of mirroring the required operator's images and creates a pruned catalog source for the OCP cluster. Some examples are below:

Explicit definition (This is recommended)

Example 1:

Definition of three operators. Two operators specify the channels, while the last compliance-operator includes all the channels.

opm_mirror_list:
  file-integrity-operator:
    channel: stable
  cluster-logging:
    channel: stable-5.8
  compliance-operator:

Example 2:

Same three operators, this time all the channels are included.

opm_mirror_list:
  file-integrity-operator:
  cluster-logging:
  compliance-operator:

Implicit definition, always includes all the channels (Prefer to use Example 2 above)

Example 3:

A pruned catalog with all operator's channels.

opm_mirror_list:
  - compliance-operator
  - file-integrity-operator
  - cluster-logging

NOTE: By default the catalog source name that can be used to create operator subscription is named mirrored-redhat-operators, can be changed with dci_catalog_source_name.

NOTE: Some operators may have other operators dependencies, for such cases the dependencies must be added to the list.

Operators installation

Operator subscriptions and installation monitoring are controlled by the dci_operators variable, which allows basic or custom installations. An example of how to define the dci_operators variable is shown below.

dci_operators:
  - name: compliance-operator
    catalog_source: mirrored-redhat-operators
    namespace: openshift-compliance
  - name: cluster-logging
    catalog_source: mirrored-redhat-operators
    namespace: openshift-logging
  - name: local-storage-operator
    catalog_source: mirrored-redhat-operators
    namespace: openshift-local-storage
    channel: stable
    starting_csv: 4.14.0-202307190803
    operator_group_name: local-storage
    skippable: true
    operator_group_spec:
      targetNamespaces:
        - openshift-local-storage
  - name: ocs-operator
    catalog_source: mirrored-redhat-operators
    namespace: openshift-storage
    operator_group_spec:
      targetNamespaces:
        - openshift-storage
    ns_labels:
      openshift.io/cluster-monitoring: "true"

Important: For a successful operator installation, ensure that the settings defined in dci_operators align with the packages available in the specified catalog_source. The following examples highlight potential misconfigurations that can cause the operator installation to fail:

Selecting an installation channel that is unavailable.
Configuring an operator group with settings not supported by the operator.
Specifying a starting CSV that is not available in the selected channel.

Operator configuration

For some operators, the agent support the operand creation by setting to true specific flags. See enable_<operator> variables above. Also, the operator configuration can be executed as part of a run during the /hooks/install.yml phase.

Install all operators from a catalog

All the operators available in a catalog can be installed on the cluster by setting install_all_from_catalog. This is mainly to test if the operators are deployable by OLM. There is no additional testing, or configuration executed after a running CSV is detected.

The catalog source namespace defaults to openshift-marketplace but that can be set using the install_all_from_catalog_source variable in case the catalog was created on a different namespace.

install_all_from_catalog: <my-ocp-catalog>
install_all_from_catalog_source: <my-ocp-catalog-namespace>

Additional Catalogs

Additional catalogs can be configured for the cluster to provide another source to install operators. Set the custom_catalogs variable with the references to the catalog images. For example:

custom_catalogs:
  - quay.io/telcoci/sriov-operator-catalog:latest
  - quay.io/telcoci/simple-demo-operator:v0.0.3
  - quay.io/telcoci/nfv-example-cnf-catalog:v0.2.9
  - icr.io/cpopen/ibm-operator-catalog:latest

All the images available in the defined catalogs will be mirrored when dci_disconnected is true and a local_image_registry is defined.

Please see the settings table for the variables names to control the Operators deployment.

Mirroring from directory

In fully disconnected environments, mirroring can be performed by loading operators previously stored in a local file. The oc mirror plugin, allows the creation of catalogs that can be stored on a USB stick that will be used later to load operators on a local image registry.

The dci-openshift-agent can consume files generated by the oc mirror plugin. The agent uploads these files to the local registry, creates the catalog source, and applies the corresponding ImageContentSourcePolicies (ICSPs). The catalog source is then used to deploy the operators enabled for testing.

The operator_catalog_dir variable should be set to a valid directory that contains one or multiple archive files generated using the oc mirror plugin. In the provided example, operator_catalog_dir: /data/ is used as the path to the archive tar files.

Subscriptions for the mirrored operators can be defined using the dci_operators variable as explained above.

Minio deployment

Some workloads like Migration Toolkit for Containers or Loki may require an object Object Storage provider. For such cases, a Minio instance can be deployed on the OCP cluster by setting true to the enable_minio flag.

In the DCI Openshift Agent integration, an initial bucket named loki is deployed and is used for the logging if no information about an external Object provider are provided.

The following variables allow customizing the Minio deployment. Please see the minio_setup role for additional details.

Variable	Default	Required	Description
minio_claim_size	10Gi	No	Requested storage for Minio
minio_storage_class	undefined	Yes	A storage Class with Support for RWX volumes
minio_namespace	minio	No	Deployment Namespace
minio_access_key_id	minioadmin	No	Minio's Initial Username
minio_access_key_secret	minioadmin	No	Minio's Initial Password
monio_bucket_name	minio	No	Initial Bucket name

The workloads that require Object Storage, can use the http://minio-service.minio:9000 endpoint and the default credentials set in the minio_setup role to start shipping data to Minio.

Logging stack

The enable_logs_stack variable allows configuring OCP to send log files and metrics produced by the infrastructure and workloads to a logging stack. This stack is integrated by the ClusterLogging, Loki and an Object storage system.

The following variables allow customizing the logs stack deployment. Please see the ocp_logging role for additional details.

Variable	Required	Type	Default	Description
logs_access_key_id	False	String	undefined	Key ID for the Object storage system.
logs_access_key_secret	False	String	undefined	Key Secret for the Object Storage system.
logs_bucket	False	String	undefined	Object Storage bucket name.
logs_endpoint	False	String	undefined	Object Storage endpoint.
logs_region	False	String	undefined	Object Storage region.
logs_loki_size	False	String	undefined	Loki Deployment Size. See Sizing for more details.
logs_storage_class	False	String	undefined	Cluster Storage class for Loki components.
logs_event_router_image	False	String	registry.redhat.io/openshift-logging/eventrouter-rhel8:v5.2.1-1	Event Router image.
logs_settings	False	String	""	An optional yaml file with the variables listed above. The variables defined there take precedence over the ones defined at role level

Enabling the openshift cluster-logging components requires high amounts of storage available for data persistency, please take this in consideration during the sizing of the Object Storage provider.

Network Observability stack

The enable_netobserv variable allows configuring the Network Observability operator to collect information about OCP network flows and traffic. This stack is integrated by the Network Observability Operator, Loki, an Object storage system and the Flow Collector.

The following variables allow customizing the Network Observability stack deployment. Please see the ocp_netobserv role for additional details.

Variable	Default	Required	Description
setup_netobserv_stackaction	'install'	No	Role's default action
setup_netobserv_stacksampling	50	No	Data sampling
setup_netobserv_stackagent_privileged	true	No	Privileged mode allows collecting data from SRIOV functions
setup_netobserv_stackagent_memory	50Mi	No	Memory assigned to the agent
setup_netobserv_stackagent_cpu	100m	No	CPU assigned to the agent
setup_netobserv_stackagent_limits_memory	800Mi	No	Memory limit for the agent
setup_netobserv_stackprocessor_memory	100Mi	No	Memory assigned to the processor

setup_netobserv_stackloki_size	1x.extra-small	No	Loki Stack size. See: Sizing for details
setup_netobserv_stackstorage_class	managed-nfs-storage	No	Storage class for the Loki Stack

The configuration setting can be passed using the dci_netobserv_conf_file containing the variables listed above.

Enabling the Openshift Network observability Operator requires high amounts of storage available for data persistency, please take this in consideration during the sizing of the Object Storage provider. By default, the stack is configured to use the internal Minio deployment as backend.

Interacting with your RHOCP Cluster

After you run a DCI job you will be able to interact with the RHOCP cluster using the OC client, the API, or the GUI.

Using the OC client
```
export KUBECONFIG=/home/<user>/<clusterconfigs-path>/kubeconfig
oc get nodes
```
A copy of the generated kubeconfig file will be attached to the job files section in DCI.
Using the GUI/API

Obtain the credentials generated during the installation from /home/<user>/<clusterconfigs-path>/ocp_creds.txt in the jumphost.

Get the the URL of the cluster GUI:
```
$ oc whoami --show-console
https://console-openshift-console.apps.<cluster>.<domain>
```

NOTE: The dci-openshift-agent is part of a Continuous integration tool aimed to perform OCP deployments, should not be considered for production workloads. Use the above connection methods if some troubleshooting is required.

Troubleshooting basic configuration

Review the following checklist to make sure you've got all the basic pieces in place:

Is the DCI repo configured?
Is the dci-openshift-agent package the latest version?
Does my credentials file contain my remote CI credentials as per the distributed-ci.io dashboard?
Does my inventory reflect my cluster's expected configuration? Check the following variables:
- cluster
- domain
- prov_nic
- pub_nic
- IPMI configuration for all nodes in OCP cluster: ipmi_user, ipmi_password, ipmi_address
- MAC addresses for all nodes in OCP cluster
Does my pipeline file reflect the right topic/component for my needs?
Is my dci-openshift-agent SSH key transferred to the provision host? e.g. can I SSH without a password from Jumpbox -> provisioner?

Troubleshooting network connectivity

First, take another look at the network requirements section and make sure your setup looks similar to the proposed basic diagram. Your particular lab may differ in how things are laid out, but the basic points to look for are:

Your provisioning network should be treated as an exclusive "out of band" network only intended to PXE boot the initial cluster OS
Your baremetal network should be capable of routing to:
- Your jumpbox
- Your cluster nodes' BMCs (e.g. your management network)
You should have outbound internet access from your Jumpbox (and OCP cluster unless in disconnected mode)
Your baremetal network should be DHCP enabled and have addresses for all of your cluster nodes plus the bootstrap VM (usually not an issue but make sure there are enough IP addresses to lease)
Your Jumpbox, provisioner, and cluster nodes all should be able to resolve your API and your wildcard DNS entries e.g. api.<cluster>.<domain> and *.apps.<cluster>.<domain>
The provision host should have 2 bridges setup: one for the provisioning network and another for the baremetal network, are both setup? Are the functional?

Here are a few things you can check to make sure the above assertions are true:

Can I query the power status of the cluster nodes from the provisioner and control-plane nodes via e.g. ipmitool?
Can I curl one of the mirror.openshift.com resources from the provisioner and cluster nodes?
Is the lab's DNS resolvable from all places via e.g. dig api.<cluster>.<domain> and dig foo.apps.<cluster>.<domain>?

Troubleshooting OCP bootstrapping

You can monitor the bootstrap/install process by logging into the provision host and tailing the file ~/clusterconfigs/.openshift_install.log.

If you're having issues once the agent gets to the point where baremetal-install is called, you can check a few things:

Check the ~/clusterconfigs/install-config.yaml.bkup file in your provision host (this is a copy of the install manifest fed to baremetal-install) and make sure the manifest looks correct
Is the bootstrap VM coming up? e.g. sudo virsh list --all should list a VM named *-bootstrap about 5-10 minutes after you started the run
Is the bootstrap VM getting IP address from the baremetal network? Run virsh console <bootstrap VM> and a linux login prompt should be visible, hit <Enter> and it should show 2 IP addresses: a DHCP one as per your configuration, and a static 172.22.0.22 on the provisioning network
Is your bootstrap VM up coming up correctly? You can ssh core@172.22.0.2 and check the status of the pods running on the system by sudo podman ps. You should see (after a few minutes) some pods named ironic-{api,conductor,inspector}
Check the logs of the ironic-* pods with sudo podman logs <pod> and look for errors/exceptions
Is your ironic-conductor able to interact with the BMCs? Try logging yourself to the pod (sudo podman exec -it ironic-conductor /bin/sh) and make sure there is connectivity to the BMC e.g. ipmi -I lanplus -H <BMC host> -U <BMC user> -P <BMC password> power status

Troubleshooting OCP install

During the deployment, ironic services are started temporally in the bootstrap VM, to help bootstrapping the master nodes. Then after the master nodes are ready to take the role, bootstrap VM is deleted and ironic services are started in the cluster. At both stages you can interact with ironic to see details of the nodes

If you want to interact with ironic services during the bootstrap, get the baremetal network IP of ironic service from the bootstrap VM

[core@localhost ~]$ sudo ss -ntpl | grep 6385
[core@localhost ~]$ ip a s ens3

Get the bootstrap VM ironic credentials from the terraform variables back in the provision host

[dci@provisionhost ~]$ grep ironic_ clusterconfigs/terraform.baremetal.auto.tfvars.json
  "ironic_username": "bootstrap-user",
  "ironic_password": "foo",

If you want to interact with ironic services in the cluster, get the IP of ironic service from the metal3 resources

[dci@provisionhost ~]$ export KUBECONFIG=/home/dci/clusterconfigs/auth/kubeconfig
[dci@provisionhost ~]$ oc -n openshift-machine-api get pods # find the metal3 pod
[dci@provisionhost ~]$ oc -n openshift-machine-api describe pod <pod> | egrep ^IP:
IP:                   192.168.123.148
[dci@provisionhost ~]$ oc -n openshift-machine-api get secrets metal3-ironic-password \
  -o jsonpath='{.data.username}' | base64 -d
ironic-user
[dci@provisionhost ~]$ oc -n openshift-machine-api get secrets metal3-ironic-password \
  -o jsonpath='{.data.password}' | base64 -d
bar

Then prepare a clouds.yaml with the following information, and replace the IP addresses and password accordingly

NOTE: Starting with OCP 4.7 metal3-boostrap service uses auth_type: http_basic, but in in older versions it uses auth_type: none so there's no need to set auth section with the credentials

clouds:
  metal3-bootstrap:
    auth_type: http_basic
    auth:
      username: bootstrap-user
      password: $BOOTSTRAP_PASSWORD
    baremetal_endpoint_override: http://IP-Provisioining-bootstrapVM-IP:6385
    baremetal_introspection_endpoint_override: http://IP-Provisioining-bootstrapVM-IP:5050
  metal3:
    auth_type: http_basic
    auth:
      username: ironic-user
      password: $IRONIC_PASSWORD
    baremetal_endpoint_override: http://IP-Provisioining-Master-IP:6385
    baremetal_introspection_endpoint_override: http://IP-Provisioining-Master-IP:5050

Back in the provisioning host, install podman and start a container, set OS_CLOUD with metal3 if you want to use the ironic services on the cluster, or metal3-bootstrap if you want to use the services on the bootstrap VM (if still running)

[dci@provisionhost ~]$ sudo dnf install -y podman
[dci@provisionhost ~]$ podman run -ti --rm \
  --entrypoint /bin/bash \
  -v /home/dci/clouds.yaml:/clouds.yaml:z \
  -e OS_CLOUD=metal3
  quay.io/metal3-io/ironic-client

Finally from the pod you started, you can run ironic baremetal commands

[root@8ce291ff4f4a /]# baremetal node list

OCP upgrades using dci-openshift-agent

Test OCP upgrades using the dci-openshift agent

The dci-openshift-agent supports testing cluster upgrades by executing an upgrade pipeline.

See below and an example of a pipeline job definition:

- name: openshift-vanilla-upgrade-4.10
  stage: ocp-upgrade
  prev_stages: [ocp-upgrade, ocp]
  ansible_playbook: /usr/share/dci-openshift-agent/dci-openshift-agent.yml
  ansible_cfg: /var/lib/dci/pipelines/ansible.cfg
  ansible_inventory: /var/lib/dci/inventories/inventory
  dci_credentials: /etc/dci-openshift-agent/dci_credentials.yml
  configuration: "@QUEUE"
  ansible_extravars:
    dci_config_dirs: [/var/lib/dci/dallas-config/dci-openshift-agent]
    dci_local_log_dir: /var/lib/dci-pipeline/upload-errors
    dci_tags: []
    dci_cache_dir: /var/lib/dci-pipeline
    dci_base_ip: "{{ ansible_default_ipv4.address }}"
    dci_baseurl: "http://{{ dci_base_ip }}"
    dci_main: upgrade
    cnf_test_suites: []
    performance_definition: /<path>/performance-profile.yml
    tuned_definition: /<path>/tuned-definition.yml
    # Operators to mirror
    opm_mirror_list:
      loki-operator:
      cluster-logging:
  topic: OCP-4.10
  components:
    - ocp
  outputs:
    kubeconfig: "kubeconfig"
  success_tag: ocp-upgrade-4.10-ok

Please note the following settings:

prev_stages: Indicates that this pipeline can only be executed after an OCP install or another OCP upgrade, as those will provide the kubeconfig used to interact with the cluster during the upgrade.
dci_main: Instructs the agent to execute only the tasks related to a cluster upgrade. Accepted values are install and upgrade.
opm_mirror_list: During the upgrade the operators already installed will be upgraded, those operators must be listed in this variable to perform the operators mirroring according to the target OCP version.

See: dci-pipeline documentation for more details about the configuration settings.

The agent supports 2 types of upgrades:

Upgrades to the next support .- release version according the OCP update graph.
Extended Update Support (EUS) upgrades, if the current cluster version is EUS supported version. See preparing EUS-EUS upgrade.

The upgrade process

Some of the relevant tasks executed during a cluster upgrade are listed below:

A DCI job is created to track the upgrade process.
The specific target version is calculated based on the OCP upgrade graph.
The target OCP release is mirrored to the same images / that was used for the cluster deployment. For EUS upgrades, the intermediate release images are also mirrored ¹.
The ISO, rootfs, and other artifacts are mirrored to the same webserver_url used for the initial cluster deployment ¹.
The Image Content Source Policies and OCP signature for the new version are applied ¹.
The "cluster version" is patched for the new target version based on the calculated target version.
The upgrade is executed and monitored for completion.
The Red Hat operators catalog for the new OCP version is pruned and mirrored according to the opm_mirror_list or dci_operators variables defined in the pipeline file ¹.
The current Red Hat operators catalog is replaced with the new one for the target OCP version.
Information about installed operators is collected based on the current subscriptions.
The operator upgrade is executed for operators not listed in the operator_skip_upgrade list.
An operator upgrade will be triggered if:
- There is a new CSV version available for the currently installed operator in the current channel.
- There is a new default channel available for the currently installed operator. That will usually imply the availability of a new CSV.
Operators' upgrade starts and is monitored until it reaches the target CSV.
Cluster resources, machine config pools, cluster operators, etc. are validated to declare a cluster as successfully upgraded.
The relevant logs and cluster information are uploaded to the "Files" section of the DCI-UI.

¹ Only in disconnected environments.

The EUS upgrade

OpenShift offers a way to facilitate the upgrade between two EUS versions. This allows upgrading between even versions, for example from ocp-4.8 to ocp-4.10. Detailed documentation is available in preparing EUS-EUS upgrade

To perform this type of upgrade with DCI, the following conditions must be met:

Activate the boolean upgrade_eus to true.
The cluster has to be installed in an EUS version.
The topic or target version must be an EUS release.

Transitioning between two OCP releases requires an intermediate version. It's possible to specify the intermediate version through version_inter, this ignores the upgrade path.

For example, to upgrade to a version where there's no path to it. Specify the intermediate version. version_inter:4.11.5 or to use candidate versions use version_inter:4.11.0-*.

Note the -*, this will help to include candidate versions in the search.

Upgrade notes:

The upgrade process is only supported when the installation was performed with the dci-openshift-agent.
For disconnected environments, it's required to mirror the same operators originally installed in the cluster in order to allow the upgrade to the version used for the upgrade.
Please see the ansible-variables section for more settings related to the upgrade process.

Custom Builds

This is a way to test with custom builds. The requirements are:

Pipeline

Must NOT contain ocp component
Must define:

  dci_custom_component: true
  dci_custom_component_file: /path/to/custom_component.json

Inventory
- Must define a pullsecret with access to the custom build image
```
  pullsecret_file: /path/to/custom_pullsecret.json
```

Example of a custom component file:

{
  "data": {
    "pull_url": "registry.<sub-domain>.ci.openshift.org/<build-id>/release@sha256:abcdef...",
    "version": "4.15.0-0.ci.test-<timestamp>-<id>"
  },
  "tags": [
    "sha256:abcdef...",
    "build:nightly"
  ],
  "id": "",
  "type": "ocp",
  "url": "https://registry.<sub-domain>.ci.openshift.org/<build-id>/release:latest"
}

Keep the DCI OCP Agent Updated

It is recommended to keep the Jumpbox server updated, enable dnf-automatic updates to make sure system is using latest dci-openshift-agent

Install dnf-automatic

# dnf install -y dnf-automatic

Modify the default configuration to enable automatic downloads and apply updates

# vi /etc/dnf/automatic.conf
...
download_updates = yes
apply_updates = yes
...

Enable the dnf-automatic.timer

# systemctl enable --now dnf-automatic.timer

Important: DNF automatic updates might fail because of a non-satisfied dependency of latest RHEL 8 with ansible 2.9, then it is recommended to add the following command in a cronjob to be executed daily basis.

# dnf upgrade --nobest --refresh --repo dci,epel -y

Getting involved

Refer to the development guide

Create your DCI account on distributed-ci.io

Every user needs to create his personal account by connecting to https://www.distributed-ci.io by using a Red Hat SSO account.

The account will be created in the DCI database at the first connection with the SSO account. For now, there is no reliable way to know your team automatically. Please contact the DCI team when this step has been reached, to be assigned in the correct organisation.
