Chapter 8. Migrating Red Hat Ansible Automation Platform to Ansible Automation Platform Operator

Procedure

1. Locate the old secret key in the inventory file you used to deploy Ansible Automation Platform in your previous installation.

2. Create a yaml file for your secret key:

   apiVersion: v1
   kind: Secret
   metadata:
     name: <resourcename>-secret-key
     namespace: <target-namespace>
   stringData:
     secret_key: <old-secret-key>
   type: Opaque

3. Apply the secret key yaml to the cluster:

   oc apply -f <secret-key.yml>

Procedure

1. Create a yaml file for your postgresql configuration secret:

   apiVersion: v1
   kind: Secret
   metadata:
     name: <resourcename>-old-postgres-configuration
     namespace: <target namespace>
   stringData:
     host: "<external ip or url resolvable by the cluster>"
     port: "<external port, this usually defaults to 5432>"
     database: "<desired database name>"
     username: "<username to connect as>"
     password: "<password to connect with>"
   type: Opaque

2. Apply the postgresql configuration yaml to the cluster:

Procedure

1. Create a yaml file to verify the connection between your new deployment and your old deployment database:

   apiVersion: v1
   kind: Pod
   metadata:
       name: dbchecker
   spec:
     containers:
       - name: dbchecker
         image: registry.redhat.io/rhel8/postgresql-13:latest
         command: ["sleep"]
         args: ["600"]

2. Apply the connection checker yaml file to your new project deployment:

   oc project ansible-automation-platform
   oc apply -f connection_checker.yaml

3. Verify that the connection checker pod is running:

   oc get pods

4. Connect to a pod shell:

   oc rsh dbchecker

5. After the shell session opens in the pod, verify that the new project can connect to your old project cluster:

   pg_isready -h <old-host-address> -p <old-port-number> -U awx

   Example

   <old-host-address>:<old-port-number> - accepting connections
