observability-operator

The Observability Operator is a Kubernetes operator which enables the management of Monitoring/Alerting stacks through Kubernetes CRDs. Eventually it might also cover Logging and Tracing.

The project relies heavily on the controller-runtime library.

Trying out the Operator

Observability Operator requires Operator Lifecycle Manager (OLM) to be running in cluster. The easiest way is to use OpenShift where OLM is preinstalled.

OpenShift

Add the Observability Operator Catalog as shown below.

kubectl apply -f hack/olm/catalog-src.yaml

This adds a new Catalog to the list of catalogs. Now, you should be able to use OLM Web interface to install/uninstall Observability Operator like any other operator.

If you prefer CLI, applying the subscription as shown below will install the operator.

kubectl create -f ./hack/olm/subscription.yaml

Uninstall

It is easier to use the web console to remove the installed operator. Instructions below removes all traces of what was setup in the previous step including removing the catalog.

oc delete -n operators csv \
    -l operators.coreos.com/observability-operator.operators=

oc delete -n openshift-operators  \
    installplan,subscriptions \
    -l operators.coreos.com/observability-operator.operators=

oc delete -f hack/olm

oc delete crds "$(oc api-resources --api-group=monitoring.rhobs -o name)"

Kubernetes

As mentioned above, Observability Operator requires Operator Lifecycle Manager (OLM) to be running in cluster, so installing OLM is the first step to getting the Observability Operator running on k8s.

operator-sdk olm install
kubectl create -f ./hack/olm/k8s/catalog-src.yaml
kubectl create -f ./hack/olm/k8s/subscription.yaml

NOTE: To install operator-sdk, you can make use of make tools which installs operator-sdk (along with other tools needed for development) to tmp/bin

For more information, about running Observability Operator (ObO) on Kind, please refer to the Developer Docs.

Uninstalling

kubectl delete -n operators csv \
    -l operators.coreos.com/observability-operator.operators=

kubectl delete -n operators  \
    installplan,subscriptions \
    -l operators.coreos.com/observability-operator.operators=

kubectl delete -f hack/olm/k8s

kubectl delete crds "$(kubectl api-resources --api-group=monitoring.rhobs -o name)"
