Installing OLM

OLM deployment resources are templated so that they can be easily configured for different deployment environments.

Installation Options

Manual installation

Installing the CRDs first gives them a chance to register before installing the rest, which requires the CRDs exist.

kubectl create -f deploy/upstream/quickstart/crds.yaml
kubectl create -f deploy/upstream/quickstart/olm.yaml

Install a Release

Check out the latest releases on github for release-specific install instructions.

OpenShift

IMPORTANT: OLM is installed by default in OpenShift 4.0 and above.

Install with operator-sdk olm install

OLM can be installed with the operator-sdk command operator-sdk olm install more information is available in the operator-sdk documentation.

Customizing OLM installation

Deployments of OLM can be stamped out with different configurations by writing a values.yaml file and running commands to generate resources.

Here's an example values.yaml

# sets the apiversion to use for rbac-resources. Change to `authorization.openshift.io` for openshift
rbacApiVersion: rbac.authorization.k8s.io
# namespace is the namespace the operators will _run_
namespace: olm
# watchedNamespaces is a comma-separated list of namespaces the operators will _watch_ for OLM resources.
# Omit to enable OLM in all namespaces
watchedNamespaces: olm
# catalog_namespace is the namespace where the catalog operator will look for global catalogs.
# entries in global catalogs can be resolved in any watched namespace
catalog_namespace: olm
# operator_namespace is the namespace where the operator runs
operator_namespace: operators

# OLM operator run configuration
olm:
  # OLM operator doesn't do any leader election (yet), set to 1
  replicaCount: 1
  # The image to run. If not building a local image, use sha256 image references
  image:
    ref: quay.io/operator-framework/olm:local
    pullPolicy: IfNotPresent
  service:
    # port for readiness/liveness probes
    internalPort: 8080

# catalog operator run configuration
catalog:
  # Catalog operator doesn't do any leader election (yet), set to 1
  replicaCount: 1
  # The image to run. If not building a local image, use sha256 image references
  image:
    ref: quay.io/operator-framework/olm:local
    pullPolicy: IfNotPresent
  service:
    # port for readiness/liveness probes
    internalPort: 8080

To configure a release of OLM for installation in a cluster:

  1. Create a my-values.yaml like the example above with the desired configuration or choose an existing one from this repository. The latest production values can be found in deploy/upstream/values.yaml.

  2. Generate deployment files from the templates and the my-values.yaml using package_release.sh

    # first arg must be a semver-compatible version string
# second arg is the output directory
# third arg is the values.yaml file
./scripts/package_release.sh 1.0.0-myolm ./my-olm-deployment my-values.yaml

  3. Deploy to kubernetes: kubectl apply -f ./my-olm-deployment/templates/

The above steps are automated for official releases with make ver=0.3.0 release, which will output new versions of manifests in deploy/tectonic-alm-operator/manifests/$(ver).

Overriding the Global Catalog Namespace

It is possible to override the Global Catalog Namespace by setting the GLOBAL_CATALOG_NAMESPACE environment variable in the catalog operator deployment.

Subscribe to a Package and Channel

Cloud Services can be installed from the catalog by subscribing to a channel in the corresponding package.

If using one of the local run options, this will subscribe to etcd, vault, and prometheus operators. Subscribing to a service that doesn't exist yet will install the operator and related CRDs in the namespace.

apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: etcd
  namespace: olm
spec:
  channel: singlenamespace-alpha
  name: etcd
  source: operatorhubio-catalog
  sourceNamespace: olm
---
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: prometheus
  namespace: olm
spec:
  channel: alpha
  name: prometheus
  source: operatorhubio-catalog
  sourceNamespace: olm

Uninstall

OLM can be uninstalled with the operator-sdk olm uninstall command. More information is available in the operator-sdk documentation
