With the help of the following playbooks let's understand how the process of Leapp Upgrade from Oracle Linux 7 to Oracle Linux 8 as documented in https://docs.oracle.com/en/operating-systems/oracle-linux/8/leapp/leapp-AboutLeapp.html#about-leapp can be automated:
- leapp_prepare.yml: Enables leapp repositories, install the leapp related pacakges, performs a yum update and prepares the system for the leapp updgrade.
- leapp_preupgrade.yml: Run the leapp Preupgrade phase, displays the inhibitors and the answer file.
- leapp_upgrade.yml: Performs the upgrade and reboots the machine.
- post_upgrade.yml: Checks the system and removes any residual Oracle Linux 7 packages.
| Variable | Required | Description |
|---|---|---|
| proxy | Yes | Values: True or False. Specifies if a proxy needs to be used. |
| my_https_proxy | Optional | If proxy is set to true, this variable takes the input of proxy. |
| leapp_switch | Yes | Values : --oraclelinux or --oci |
- Ensure the credentials, Inventories and Projects are created.
- Create a template for each of the four playbooks mentioned above. To simplify the process further, Create a Workflow template in the order leapp_prepare --> leapp_preupgrade --> leapp_upgrade --> leapp_posyupgrade.
- Add the extra variables as required to each template. Example : {"leapp_swicth":"--oraclelinux"}
- Ensure Inventory file is created/updated pointing to the target hosts.
- Execute each of the playbooks with commands similar to below:
#ansible-playbook leapp_prepare.yml -e '{"proxy":"yes","my_https_proxy":"http://proxy:proxyport"}'
#ansible-playbook leapp_preupgrade.yml -e '{"leapp_switch":"--oraclelinux","my_https_proxy":"http://proxy:proxyport"}'
#ansible-playbook leapp_upgrade.yml -e '{"leapp_switch":"--oraclelinux"}'
