This is a image for generating ignition manifests & kubeconfig

  1. Dockerfile (depricated) - dockerfile for building the assisted-ignition-generator image with openshift-installer platform none
  2. Dockerfile.baremetal - dockerfile for building the assisted-ignition-generator image with openshift-installer platform baremetal
  3. installer_dir/install-config.yaml - example of install-config.yaml for none platform
  4. installer_dir/install-config.yaml.baremetal - example of install-config.yaml for baremetal platform.
  5. openshift-install - executable that produces ignition files. It is copied from installer repository before issuing docker build command. Should be build in accordance with the platform we are running on a) none platform - should be build with command <TAGS="none" hack/build.sh> b) baremetal platform - should be build with command <TAGS="baremetal" hack/build.sh>. Prior to that the following files in the installer souce code should be changed: - hack/build.sh - CGO_ENABLED flag should be enable in case of baremetal platform also: <if (echo "${TAGS}" | grep -q 'libvirt|baremetal')> - pkg/types/baremetal/validation/libvirt.go - build tag should be changed from baremetal to libvirt ( to avoid validations via libvirt)

Building:

  1. currently we use our own openshift-install executable. We save it into the containener using Dockerfile.installer-image and pushing it to a repository ( make sure ot make it public. Currently we use quay.io/yshnaidm/openshift-installer. In case we recompile openshift-install, we need to update this image: docker build -f Dockerfile.installer-image -t . Example: docker build -f Dockerfile.installer-image -t quay.io/yshnaidm/openshift-installer:latest .
  2. we are using the image built in step 1 to get the needed openshift-install. Once we start using openshift-install from the release, we can update Dockerfile.baremetal accordingly docker build -f Dockerfile.baremetal . -t quay.io/ocpmetal/assisted-ignition-generator:stable

Testing:

Testing can be done in 2 stages:

  1. test generation of the ignition files , locally on your laptop. a) copy install-config.yaml.baremetal to installer-config.yaml in installer_dir. b) run assisted-ignition-generator image that you previously created.

    docker run -v $(pwd)/installer_dir:/data/installer_dir -it assisted-ignition-generator:ad6939c67c115cef7877ab7d06d72f2d06cebe0

    if no error is printed, then the ignition files are generated in the nstaller_dir

  2. test specific manipulations on generated ignition. Currently only BMH annotations generations is checked. This stage must be run only after first stage a) change permissions of the file generated in the first stage. from installer_dir run: sudo chmod -R 777 auth bootstrap.ign master.ign metadata.json worker.ign .openshift_install.log .openshift_install_state.json b) run: skipper run python3 test_bmh_annotations.py

Usage:

                                                       [--s3_bucket S3_BUCKET]
