Quick Start - Helm Chart

If you want to give a quick try of the operator without the whole glory of OLM you can deploy our Operator using Helm.

• Start minikube:

minikube start --addons=ingress,dashboard

• Install the Helm Chart:

helm install myhelm helm/

• Create an instance of Trustify:

cat << EOF | kubectl apply -f -
apiVersion: "org.trustify/v1alpha1"
kind: "Trustify"
metadata:
  name: myapp
spec: { }
EOF

Local development

Minikube

• Start minikube:

minikube start --addons=ingress,dashboard
curl -sL https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.30.0/install.sh | bash -s v0.30.0

• Setup ServiceAccount + Role + RoleBinding:

kubectl apply -f scripts/rbac.yaml

• Start server in dev mode

mvn compile quarkus:dev

• Create an instance of the operator:

kubectl apply -f scripts/trustify.yaml

At this point the container images will be generated by the operator.

Test Operator

export IMG=quay.io/${USER}/trustify-operator:v0.0.0
export BUNDLE_IMG=quay.io/${USER}/trustify-operator-bundle:v0.0.0
export CATALOG_IMG=quay.io/${USER}/trustify-operator-catalog:v0.0.0

• Create operator:

make docker-build docker-push

• Create bundle:

make bundle-build bundle-push

• Create catalog:

make catalog-build catalog-push

Instantiate Catalog

• If you are using Minikube:

CATALOG_NAMESPACE=olm

• If you are using OCP:

CATALOG_NAMESPACE=openshift-marketplace

• Instantiate catalog:

cat <<EOF | kubectl apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: trustify-catalog-source
  namespace: $CATALOG_NAMESPACE
spec:
  sourceType: grpc
  image: $CATALOG_IMG
EOF

At this point you can see the Operator in the marketplace of OCP ready for you to test it.

Create subscription

• Create namespace:

kubectl create ns trustify

• Create group

cat <<EOF | kubectl apply -f -
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: operatorgroup
  namespace: trustify
spec:
  targetNamespaces:
    - trustify
EOF

• Create subscription:

cat <<EOF | kubectl apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: trustify-subscription
  namespace: trustify
spec:
  channel: alpha
  name: trustify-operator
  source: trustify-catalog-source
  sourceNamespace: ${CATALOG_NAMESPACE}
EOF

Instantiate Trustify

cat <<EOF | kubectl apply -n trustify -f -
apiVersion: "org.trustify/v1alpha1"
kind: "Trustify"
metadata:
  name: myapp
spec: { }
EOF
