Deploying demo aap instance

• Login to cluster
• Create kubernetes namespace
• Subscribe to aap operator
• Create aap custom resource

This guide will outline the steps to follow to deploy a demo ansible automation platform instance to an existing kubernetes cluster. For our purposes that cluster will be an existing ROSA cluster running in AWS ap-southeast-1.

Login to cluster

As mentioned above we have an existing OpenShift cluster to use for this demo, we will need to login to the cli to automate the remainder of the jira setup.

oc login --kubeconfig ~/.kube/rosa --token=<token> --server=<server>

Create kubernetes namespace

Our first step is to create a kubernetes namespace for our aap deployment.

kubectl --kubeconfig ~/.kube/rosa create namespace aap

Subscribe to aap operator

Once we have a namespace we can create a Subscription custom resource to install the latest version of the Ansible Automation Platform operator.

cat << EOF | kubectl --kubeconfig ~/.kube/rosa apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: ansible-automation-platform-operator
  namespace: aap
spec:
  channel: stable-2.3
  installPlanApproval: Automatic
  name: ansible-automation-platform-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace
  startingCSV: aap-operator.v2.3.0-0.1677639985
EOF

Create aap custom resource

Once the operator is installed we can create an AutomationController custom resource as outlined below:

cat << EOF | kubectl --kubeconfig ~/.kube/rosa apply -f -
apiVersion: automationcontroller.ansible.com/v1beta1
kind: AutomationController
metadata:
  name: aap-demo
  namespace: aap
spec:
  create_preload_data: false
  route_tls_termination_mechanism: Edge
  garbage_collect_secrets: false
  ingress_type: Route
  loadbalancer_port: 80
  image_pull_policy: IfNotPresent
  projects_storage_size: 8Gi
  task_privileged: false
  projects_storage_access_mode: ReadWriteMany
  projects_persistence: false
  replicas: 1
  admin_user: admin
  loadbalancer_protocol: http
  nodeport_port: 30080
EOF

We can obtain the route to access the instance with the command below:

echo https://$(oc --kubeconfig ~/.kube/rosa --namespace aap get route | grep apps.com | awk '{print $2}')
