title: "Digital Rebar" | ||
description: "In this guide we will create an Kubernetes cluster with 1 worker node, and 2 controlplane nodes using an existing digital rebar deployment." | ||
--- | ||
|
||
## Prerequisites | ||
|
||
- 3 nodes (please see [hardware requirements](../../guides/getting-started#system-requirements)) | ||
- Loadbalancer | ||
- Digital Rebar Server | ||
- Talosctl access (see [talosctl setup](../../guides/getting-started/talosctl)) | ||
|
||
## Creating a Cluster | ||
|
||
In this guide we will create an Kubernetes cluster with 1 worker node, and 2 controlplane nodes. | ||
We assume an existing digital rebar deployment, and some familiarity with iPXE. | ||
|
||
We leave it up to the user to decide if they would like to use static networking, or DHCP. | ||
The setup and configuration of DHCP will not be covered. | ||
|
||
### Create the Machine Configuration Files | ||
|
||
#### Generating Base Configurations | ||
|
||
Using the DNS name of the load balancer, generate the base configuration files for the Talos machines: | ||
|
||
```bash | ||
$ talosctl gen config talos-k8s-metal-tutorial https://<load balancer IP or DNS>:<port> | ||
created controlplane.yaml | ||
created worker.yaml | ||
created talosconfig | ||
``` | ||
|
||
> The loadbalancer is used to distribute the load across multiple controlplane nodes. | ||
> This isn't covered in detail, because we asume some loadbalancing knowledge before hand. | ||
> If you think this should be added to the docs, please [create a issue](https://github.com/talos-systems/talos/issues). | ||
At this point, you can modify the generated configs to your liking. | ||
Optionally, you can specify `--config-patch` with RFC6902 jsonpatch which will be applied during the config generation. | ||
|
||
#### Validate the Configuration Files | ||
|
||
```bash | ||
$ talosctl validate --config controlplane.yaml --mode metal | ||
controlplane.yaml is valid for metal mode | ||
$ talosctl validate --config worker.yaml --mode metal | ||
worker.yaml is valid for metal mode | ||
``` | ||
|
||
#### Publishing the Machine Configuration Files | ||
|
||
Digital Rebar has a build-in fileserver, which means we can use this feature to expose the talos configuration files. | ||
We will place `controlplane.yaml`, and `worker.yaml` into Digital Rebar file server by using the `drpcli` tools. | ||
|
||
Copy the generated files from the step above into your Digital Rebar installation. | ||
|
||
```bash | ||
drpcli file upload <file>.yaml as <file>.yaml | ||
``` | ||
|
||
Replacing `<file>` with controlplane or worker. | ||
|
||
### Download the boot files | ||
|
||
Download a recent version of `boot.tar.gz` from [github.](https://github.com/talos-systems/talos/releases/) | ||
|
||
Upload to DRB: | ||
|
||
```bash | ||
$ drpcli isos upload boot.tar.gz as talos.tar.gz | ||
{ | ||
"Path": "talos.tar.gz", | ||
"Size": 96470072 | ||
} | ||
``` | ||
|
||
We have some Digital Rebar [example files](https://github.com/talos-systems/talos/tree/master/hack/test/digitalrebar/) in the Git repo you can use to provision Digital Rebar with drpcli. | ||
|
||
To apply these configs you need to create them, and then apply them as follow: | ||
|
||
```bash | ||
$ drpcli bootenvs create talos | ||
{ | ||
"Available": true, | ||
"BootParams": "", | ||
"Bundle": "", | ||
"Description": "", | ||
"Documentation": "", | ||
"Endpoint": "", | ||
"Errors": [], | ||
"Initrds": [], | ||
"Kernel": "", | ||
"Meta": {}, | ||
"Name": "talos", | ||
"OS": { | ||
"Codename": "", | ||
"Family": "", | ||
"IsoFile": "", | ||
"IsoSha256": "", | ||
"IsoUrl": "", | ||
"Name": "", | ||
"SupportedArchitectures": {}, | ||
"Version": "" | ||
}, | ||
"OnlyUnknown": false, | ||
"OptionalParams": [], | ||
"ReadOnly": false, | ||
"RequiredParams": [], | ||
"Templates": [], | ||
"Validated": true | ||
} | ||
``` | ||
|
||
```bash | ||
drpcli bootenvs update talos - < bootenv.yaml | ||
``` | ||
|
||
> You need to do this for all files in the example directory. | ||
> If you don't have access to the `drpcli` tools you can also use the webinterface. | ||
It's important to have a corresponding SHA256 hash matching the boot.tar.gz | ||
|
||
#### Bootenv BootParams | ||
|
||
We're using some of Digital Rebar build in templating to make sure the machine gets the correct role assigned. | ||
|
||
`talos.platform=metal talos.config={{ .ProvisionerURL }}/files/{{.Param \"talos/role\"}}.yaml"` | ||
|
||
This is why we also include a `params.yaml` in the example directory to make sure the role is set to one of the following: | ||
|
||
- controlplane | ||
- worker | ||
|
||
The `{{.Param \"talos/role\"}}` then gets populated with one of the above roles. | ||
|
||
### Boot the Machines | ||
|
||
In the UI of Digital Rebar you need to select the machines you want te provision. | ||
Once selected, you need to assign to following: | ||
|
||
- Profile | ||
- Workflow | ||
|
||
This will provision the Stage and Bootenv with the talos values. | ||
Once this is done, you can boot the machine. | ||
|
||
To understand the boot process, we have a higher level overview located at [metal overview](../overview). | ||
|
||
### Bootstrap Etcd | ||
|
||
To configure `talosctl` we will need the first control plane node's IP: | ||
|
||
Set the `endpoints` and `nodes`: | ||
|
||
```bash | ||
talosctl --talosconfig talosconfig config endpoint <control plane 1 IP> | ||
talosctl --talosconfig talosconfig config node <control plane 1 IP> | ||
``` | ||
|
||
Bootstrap `etcd`: | ||
|
||
```bash | ||
talosctl --talosconfig talosconfig bootstrap | ||
``` | ||
|
||
### Retrieve the `kubeconfig` | ||
|
||
At this point we can retrieve the admin `kubeconfig` by running: | ||
|
||
```bash | ||
talosctl --talosconfig talosconfig kubeconfig . | ||
``` |

title: "Equinix Metal" | ||
description: "Creating Talos cluster using Enquinix Metal." | ||
--- | ||
|
||
## Prerequisites | ||
|
||
This guide assumes the user has a working API token, the Equinix Metal CLI installed, and some familiarity with the CLI. | ||
|
||
## Network Booting | ||
|
||
To install Talos to a server a working TFTP and iPXE server are needed. | ||
How this is done varies and is left as an exercise for the user. | ||
In general this requires a Talos kernel vmlinuz and initramfs. | ||
These assets can be downloaded from a given [release](https://github.com/talos-systems/talos/releases). | ||
|
||
## Special Considerations | ||
|
||
### PXE Boot Kernel Parameters | ||
|
||
The following is a list of kernel parameters required by Talos: | ||
|
||
- `talos.platform`: set this to `packet` | ||
- `init_on_alloc=1`: required by KSPP | ||
- `slab_nomerge`: required by KSPP | ||
- `pti=on`: required by KSPP | ||
|
||
### User Data | ||
|
||
<!-- textlint-disable one-sentence-per-line --> | ||
|
||
To configure a Talos you can use the metadata service provide by Equinix Metal. | ||
It is required to add a shebang to the top of the configuration file. | ||
The shebang is arbitrary in the case of Talos, and the convention we use is `#!talos`. | ||
|
||
<!-- textlint-enable one-sentence-per-line --> | ||
|
||
## Creating a Cluster via the Equinix Metal CLI | ||
|
||
### Control Plane Endpoint | ||
|
||
The strategy used for an HA cluster varies and is left as an exercise for the user. | ||
Some of the known ways are: | ||
|
||
- DNS | ||
- Load Balancer | ||
- BPG | ||
|
||
### Create the Machine Configuration Files | ||
|
||
#### Generating Base Configurations | ||
|
||
Using the DNS name of the loadbalancer created earlier, generate the base configuration files for the Talos machines: | ||
|
||
```bash | ||
$ talosctl gen config talos-k8s-aws-tutorial https://<load balancer IP or DNS>:<port> | ||
created controlplane.yaml | ||
created worker.yaml | ||
created talosconfig | ||
``` | ||
|
||
Now add the required shebang (e.g. `#!talos`) at the top of `controlplane.yaml`, and `worker.yaml` | ||
At this point, you can modify the generated configs to your liking. | ||
Optionally, you can specify `--config-patch` with RFC6902 jsonpatch which will be applied during the config generation. | ||
|
||
#### Validate the Configuration Files | ||
|
||
```bash | ||
talosctl validate --config controlplane.yaml --mode metal | ||
talosctl validate --config worker.yaml --mode metal | ||
``` | ||
|
||
> Note: Validation of the install disk could potentially fail as the validation | ||
> is performed on you local machine and the specified disk may not exist. | ||
#### Create the Control Plane Nodes | ||
|
||
```bash | ||
packet device create \ | ||
--project-id $PROJECT_ID \ | ||
--facility $FACILITY \ | ||
--ipxe-script-url $PXE_SERVER \ | ||
--operating-system "custom_ipxe" \ | ||
--plan $PLAN\ | ||
--hostname $HOSTNAME\ | ||
--userdata-file controlplane.yaml | ||
``` | ||
|
||
> Note: The above should be invoked at least twice in order for `etcd` to form quorum. | ||
#### Create the Worker Nodes | ||
|
||
```bash | ||
packet device create \ | ||
--project-id $PROJECT_ID \ | ||
--facility $FACILITY \ | ||
--ipxe-script-url $PXE_SERVER \ | ||
--operating-system "custom_ipxe" \ | ||
--plan $PLAN\ | ||
--hostname $HOSTNAME\ | ||
--userdata-file worker.yaml | ||
``` | ||
|
||
### Bootstrap Etcd | ||
|
||
Set the `endpoints` and `nodes`: | ||
|
||
```bash | ||
talosctl --talosconfig talosconfig config endpoint <control plane 1 IP> | ||
talosctl --talosconfig talosconfig config node <control plane 1 IP> | ||
``` | ||
|
||
Bootstrap `etcd`: | ||
|
||
```bash | ||
talosctl --talosconfig talosconfig bootstrap | ||
``` | ||
|
||
### Retrieve the `kubeconfig` | ||
|
||
At this point we can retrieve the admin `kubeconfig` by running: | ||
|
||
```bash | ||
talosctl --talosconfig talosconfig kubeconfig . | ||
``` |
