Machine API operator

machine-api-operator

Operator for rendering, deploying and updating cluster-api components:

• Aggregated API server
• Controller manager
• Machine controller (AWS actuator)

The cluster-api is leveraged by OpenShift for running machines under the machine-api control.

Manual deployment (for Kubernetes cluster)

In order to deploy the machine-api-operator from scratch, one needs to:

1. create tectonic-system namespace

2. create CRD definition and AppVersion manifest:

   apiVersion: tco.coreos.com/v1
   kind: AppVersion
   metadata:
     name: machine-api
     namespace: tectonic-system
     labels:
       managed-by-channel-operator: "true"
   spec:
     desiredVersion:
     paused: false
   status:
     currentVersion:
     paused: false
   upgradereq:  1
   upgradecomp: 0

3. Build:

   make build

   and run the machine-api-operator binary:

   ./bin/machine-api-operator --kubeconfig ${HOME}/.kube/config  --config pkg/render/machine-api-operator-config.yaml --manifest-dir manifests

CI & tests

Tests are located in machine-api-operator repository and executed with make test in prow CI system. A link to failing tests is published as a comment in PR by @openshift-ci-robot. Current test status for all OpenShift components can be found in https://deck-ci.svc.ci.openshift.org.

CI configuration is stored in openshift/release repository and is split into 3 files:

• cluster/ci/config/prow/plugins.yaml - says which prow plugins are available and where job config is stored
• ci-operator/config/openshift/machine-api-operator/master.json - configuration for machine-api-operator component repository
• ci-operator/jobs/openshift/machine-api-operator/openshift-machine-api-operator-presubmits.yaml - prow jobs configuration for presubmits
• ci-operator/jobs/openshift/machine-api-operator/openshift-machine-api-operator-postsubmits.yaml - prow jobs configuration for postsubmits

More information about those files can be found in ci-operator onboarding file

Initial configuration for machine-api-operator CI pipeline can be found in PR #1095.
