Kubernetes Cluster-based Packaging Solution

Single package build task

Design logic

• Deploy the Kubernetes cluster in the x86-64 and AArch64 architectures.
• Configure the cluster as Jenkins slave.
• Jenkins master runs in the Kubernetes cluster in the x86-64 architecture.

Pipeline job

Only one instance is running for the same task.

trigger

• GitCode triggering
• The gating task is executed at the same time. The CPU architecture is not limited. If the task fails, the task is stopped and a comment is added to the PR.
• Parameters are successfully transferred to the downstream job.
  • Project name (repo)
  • Branch (branch)
  • Id of the Pull Request (prid)
  • Initiator (committer)

multiarch

• The x86_64 and AArch64 architectures are supported.
• Triggered after the trigger task is successful.
• Run the osc_build_k8s.py on GitCode for building.

comment

• Collect the gating and build results.
• Call the API [Submit a comment on the pull request] to send the result to GitCode.
• The CPU architecture is not limited.

Creating a Jenkins/obs image

Mechanism

• The docker service is deployed in the Kubernetes cluster. The internal service address provided for external systems is tcp://docker.jenkins:2376.
• Install the docker plugin on Jenkins and connect it to the docker service in the Kubernetes cluster.
• Configure the image creation pipeline task obs-image in Jenkins.
• Triggering mode: After the tag is added to the code repository ci_check, the task is manually triggered. The build with parameterrs plugin must be installed on Jenkins.

Pipeline task obs-image

The Kubernetes agent that runs the task must have the docker client.

Task: _trigger

• (Optional) Check the Dockerfile.
• Set parameters.
  • name [jenkins/obs]
  • version [obtained from the tag]

Task: build-image-aarch64 & build-image-x86-64

• Select Build/Publish Docker Image in the build process.
• Configure the Registry Credentials for pushing images.

Task: manifest

Multi-arch support
