Chapter 5. Installing Ansible Automation Platform Operator from the OpenShift Container Platform CLI

Use these instructions to install the Ansible Automation Platform Operator on Red Hat OpenShift Container Platform from the OpenShift Container Platform command-line interface (CLI) using the oc command.

5.1. Prerequisites

  • Access to Red Hat OpenShift Container Platform using an account with operator installation permissions.
  • The OpenShift Container Platform CLI oc command is installed on your local system. Refer to Installing the OpenShift CLI in the Red Hat OpenShift Container Platform product documentation for further information.

  1. Create a project for the operator 

    oc new-project ansible-automation-platform
    Copy to Clipboard Toggle word wrap
  2. Create a file called sub.yaml.

  3. Add the following YAML code to the sub.yaml file. 

    ---
apiVersion: v1
kind: Namespace
metadata:
  labels:
    openshift.io/cluster-monitoring: "true"
  name: ansible-automation-platform
---
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: ansible-automation-platform-operator
  namespace: ansible-automation-platform
spec:
  targetNamespaces:
    - ansible-automation-platform
---
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: ansible-automation-platform
  namespace: ansible-automation-platform
spec:
  channel: 'stable-2.1'
  installPlanApproval: Automatic
  name: ansible-automation-platform-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace
---
apiVersion: automationcontroller.ansible.com/v1beta1
kind: AutomationController
metadata:
  name: example
  namespace: ansible-automation-platform
spec:
  replicas: 1
    Copy to Clipboard Toggle word wrap

    This file creates a Subscription object called ansible-automation-platform that subscribes the ansible-automation-platform namespace to the ansible-automation-platform-operator operator.

    It then creates an AutomationController object called example in the ansible-automation-platform namespace.

    To change the Automation controller name from example, edit the name field in the kind: AutomationController section of sub.yaml and replace <automation_controller_name> with the name you want to use: 

    apiVersion: automationcontroller.ansible.com/v1beta1
kind: AutomationController
metadata:
  name: <automation_controller_name>
  namespace: ansible-automation-platform
    Copy to Clipboard Toggle word wrap

  4. Run the oc apply command to create the objects specified in the sub.yaml file: 

    oc apply -f sub.yaml
    Copy to Clipboard Toggle word wrap

To verify that the namespace has been successfully subscribed to the ansible-automation-platform-operator operator, run the oc get subs command: 

$ oc get subs -n ansible-automation-platform
Copy to Clipboard Toggle word wrap

For further information about subscribing namespaces to operators, see Installing from OperatorHub using the CLI in the Red Hat OpenShift Container Platform Operators guide.

You can use the OpenShift Container Platform CLI to fetch the web address and the password of the Automation controller that you created.

To login to the Automation controller, you need the web address and the password.

5.3.1. Fetching the automation controller web address
Copia collegamento

A Red Hat OpenShift Container Platform route exposes a service at a host name, so that external clients can reach it by name. When you created the automation controller instance, a route was created for it. The route inherits the name that you assigned to the automation controller object in the YAML file.

Use the following command to fetch the routes: 

oc get routes -n <controller_namespace>
Copy to Clipboard Toggle word wrap

In the following example, the example automation controller is running in the ansible-automation-platform namespace. 

$ oc get routes -n ansible-automation-platform

NAME      HOST/PORT                                              PATH   SERVICES          PORT   TERMINATION     WILDCARD
example   example-ansible-automation-platform.apps-crc.testing          example-service   http   edge/Redirect   None
Copy to Clipboard Toggle word wrap

The address for the automation controller instance is example-ansible-automation-platform.apps-crc.testing.

5.3.2. Fetching the automation controller password
Copia collegamento

The YAML block for the automation controller instance in sub.yaml assigns values to the name and admin_user keys. Use these values in the following command to fetch the password for the automation controller instance. 

oc get secret/<controller_name>-<admin_user>-password -o yaml
Copy to Clipboard Toggle word wrap

The default value for admin_user is admin. Modify the command if you changed the admin username in sub.yaml.

The following example retrieves the password for an automation controller object called example: 

oc get secret/example-admin-password -o yaml
Copy to Clipboard Toggle word wrap

The password for the automation controller instance is listed in the metadata field in the output: 

$ oc get secret/example-admin-password -o yaml

apiVersion: v1
data:
  password: ODzLODzLODzLODzLODzLODzLODzLODzLODzLODzLODzL
kind: Secret
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: '{"apiVersion":"v1","kind":"Secret","metadata":{"labels":{"app.kubernetes.io/component":"automationcontroller","app.kubernetes.io/managed-by":"automationcontroller-operator","app.kubernetes.io/name":"example","app.kubernetes.io/operator-version":"","app.kubernetes.io/part-of":"example"},"name":"example-admin-password","namespace":"ansible-automation-platform"},"stringData":{"password":"88TG88TG88TG88TG88TG88TG88TG88TG"}}'
  creationTimestamp: "2021-11-03T00:02:24Z"
  labels:
    app.kubernetes.io/component: automationcontroller
    app.kubernetes.io/managed-by: automationcontroller-operator
    app.kubernetes.io/name: example
    app.kubernetes.io/operator-version: ""
    app.kubernetes.io/part-of: example
  name: example-admin-password
  namespace: ansible-automation-platform
  resourceVersion: "185185"
  uid: 39393939-5252-4242-b929-665f665f665f
Copy to Clipboard Toggle word wrap

For this example, the password is 88TG88TG88TG88TG88TG88TG88TG88TG.
