OKD CoreOS Build Pipeline

All the necessary yaml files to deploy a generic tekton pipeline to build a CoreOS image using coreos-assembler.

NB This is a WIP

Description

The list of tasks are :

• cosa-init
• cosa-build
• cosa-buildextend
• cosa-test
• cosa-upload-images
• rpm-artifacts-copy

The pipeline uses kvm-device-plugin, which is now part of KubeVirt.

Installation

Clone the repository:

git clone https://github.com/okd-project/okd-coreos-pipeline.git

• For local (Kind or other) clusters, execute the following commands:

  # assume you logged into your local cluster
  
  # install tekton if you haven't already
  kubectl apply -f https://storage.googleapis.com/tekton-releases/operator/latest/release.yaml
  
  # the local overlay includes a device-plugin-kvm daemonset
  kubectl apply -k overlays/local
  
  # check that all resources have deployed
  kubectl get all -n okd-coreos-pipeline

  Once all pods are in the RUNNING status create a secret that will allow you to push to the selected registry (pipelineRun parameter target-repository), as in the example below:

  Sample secret file:

  apiVersion: v1
  kind: Secret
  metadata:
    name: my-secret
  data:
    .dockerconfigjson: ewo...p9
  type: kubernetes.io/dockerconfigjson

  Use this command to create the secret:

  kubectl apply -f ./my-secret.yaml -n okd-coreos-pipeline

• OKD team members may do the following for deploying to the OperateFirst by executing the following commands:

  # assume you logged into your kubernetes cluster on OperateFirst
  kubectl apply -k overlays/operate-first
  
  # check that all resources have deployed
  kubectl get all -n okd-team

Usage

Execute the following to start a pipelinerun locally:

kubectl create \
    -n okd-coreos-pipeline \
    -f overlays/local/pipelineruns/okd-coreos-build-4.12-pipelinerun.yaml

# see the logs
tkn pipelinerun logs -f \
    -n okd-coreos-pipeline \
    okd-coreos-build-4.12-pipelinerun-fooba

On OperateFirst, run:

kubectl create \
    -n okd-team \
    -f overlays/operate-first/pipelineruns/okd-coreos-all-4.12-pipelinerun.yaml

# see the logs
tkn pipelinerun logs -f \
    -n okd-team \
    okd-coreos-all-4.12-pipelinerun-fooba

TODO

• Build and test images for more platforms
• Control the previous build, so that we build when needed
