buildbricks/serverless-operator

An aggregation of serverless services

Red Hat Serverless Operator

Provides a collection of API's to support deploying and serving of serverless applications and functions.

Operator Framework

This repository contains the metadata required by the Operator Lifecycle Manager

Create a CatalogSource

The catalog.sh script should yield a valid ConfigMap and CatalogSource comprised of the ClusterServiceVersions, CustomResourceDefinitions, and package manifest in the bundle beneath olm-catalog/. You should apply its output in the OLM namespace:

OLM_NS=$(kubectl get deploy --all-namespaces | grep olm-operator | awk '{print $1}')
./hack/catalog.sh | kubectl apply -n $OLM_NS -f -

Using OLM on Minikube

You can test the operator using minikube after installing OLM on it:

minikube start
kubectl apply -f https://github.com/operator-framework/operator-lifecycle-manager/releases/download/0.11.0/crds.yaml
kubectl apply -f https://github.com/operator-framework/operator-lifecycle-manager/releases/download/0.11.0/olm.yaml

Once all the pods in the olm namespace are running, install the operator like so:

./hack/catalog.sh | kubectl apply -n $OLM_NS -f -

Interacting with OLM is possible using kubectl but the OKD console is "friendlier". If you have docker installed, use this script to fire it up on http://localhost:9000.

Using kubectl

To install Knative Serving into the knative-serving namespace, simply subscribe to the operator by running this script:

OLM_NS=$(kubectl get og --all-namespaces | grep olm-operators | awk '{print $1}')
OPERATOR_NS=$(kubectl get og --all-namespaces | grep global-operators | awk '{print $1}')
cat <<-EOF | kubectl apply -f -
