Release Instructions

1. Production agent image and automatic deployment to CIPROD cluster

Here are the high-level instructions to get the CIPROD:MAJOR.MINOR.PATCH image for the production release

  1. create feature branch from ci_dev and make the following updates

    Note: This required since Azure Dev Ops pipeline doesnt support --build-arg yet to automate this.

    • Ensure IMAGE_TAG updated with release candiate image tag in the DockerFile under kubernetes/linux and kubernetes/windows directory
    • Update the version file under build directory with build version and date
    • Update ama-logs.yaml for the image tag and dockerProviderVersion, and any other changes
    • Update the chart version and image tags in values.yaml under charts/azuremonitor-containers
    • Release notes
  2. Make PR to ci_dev branch and once the PR approved, merge the changes to ci_dev
  3. Latest bits of ci_dev automatically deployed to CIDEV cluster in build subscription so just validated E2E to make sure everthing works
  4. If everything validated in DEV, make merge PR from ci_dev and ci_prod and merge once this reviewed by dev team
  5. Once the PR to ci_prod approved, please go-ahead and merge, and wait for ci_prod build successfully completed
  6. Once the merged PR build successfully completed, update the value of AGENT_IMAGE_TAG_SUFFIX pipeline variable by editing the Release ci-prod-release

    Note - value format of AGENT_IMAGE_TAG_SUFFIX pipeline should be in MAJOR.MINOR.PATCH for our releases

  7. Create a release by selecting the targetted build version of the _docker-provider_Official-ci_prod release
  8. Validate all the scenarios against clusters in build subscription and scale clusters

2. Perf and scale testing

Deploy latest ama-logs yaml with release candidate agent image in to supported k8s versions and validate all the critical scenarios. In perticular, throughly validate the updates going as part of this release and also make sure no regressions. If this passes, deploy onto scale cluster and validate perf and scale aspects. Scale cluster in AME cloud and co-ordinate with agent team who has access to this cluster to deploy the release candiate onto this cluster.

3. Production Image to MCR CN for Azure China Cloud

Image automatically synched to MCR CN from Public cloud MCR.
