OLM Integration Package Manifests Quickstart

This guide assumes you have followed the introduction and Setup section of the bundle quickstart, and have added the packagemanifests target to your Makefile as described here.

Important: this guide assumes your project was scaffolded with operator-sdk init --project-version=3. These features are unavailable to projects of version 2 or less; this information can be found by inspecting your PROJECT file’s version value.

Creating package manifests

We will now create a package manifests format by running make packagemanifests in the root of the memcached-operator project:

$ make packagemanifests
/home/user/go/bin/controller-gen "crd:trivialVersions=true" rbac:roleName=manager-role webhook paths="./..." output:crd:artifacts:config=config/crd/bases
operator-sdk generate kustomize manifests -q
kustomize build config/manifests | operator-sdk generate packagemanifests -q --version 0.0.1

A versioned manifests directory packagemanifests/0.0.1 containing a CSV and all CRDs in config/crds and a package manifest YAML file packagemanifests/<project-name>.package.yaml have been created in the Operator project.

Deploying an Operator with OLM

At this point in development we’ve generated all files necessary to build a memcached-operator registry. Now we’re ready to test the Operator with OLM.

Testing package manifests

operator-sdk run packagemanifests will create an Operator registry from manifests and metadata in the memcached-operator project, and inform OLM that memcached-operator v0.0.1 is ready to be deployed. This process effectively replicates production deployment in a constrained manner to make sure OLM can deploy our Operator successfully before attempting real production deployment.

run packagemanifests performs some optionally configurable setup under the hood, but for most use cases the following invocation is all we need:

$ operator-sdk run packagemanifests --version 0.0.1

memcacheds.cache.example.com    default      CustomResourceDefinition    Installed
memcached-operator.v0.0.1       default      ClusterServiceVersion       Installed

As long as both the ClusterServiceVersion and all CustomResourceDefinition's return an Installed status, the memcached-operator has been deployed successfully.

Now that we’re done testing the memcached-operator, we should probably clean up the Operator’s resources. operator-sdk cleanup will do this for you:

$ operator-sdk cleanup memcached-operator
INFO[0000] subscription "memcached-operator-v0-0-1-sub" deleted
