rfe-ansible-edge-mgmt
Ansible automation to provision an RHEL for Edge Environments.
Prerequisites
Download dependencies
Execute the following commands to download the required dependencies
$ ansible-galaxy role install -r collections/requirements.yaml
Populate Inventory
Add the Image Builder instance(s) into the hosts file.
Subscription Information
The content within this repository leverages Red Hat RPM's. The automation to manage subscribing the machines and repositories makes use of the rhsm role within the infra-ansible repository.
It is recommended to add the necessary values to a separate file and inject it in as an extra parameter using -e @<filename> when executing the playbook. An example can be found below:
---
rhsm_username: "<password>"
rhsm_password: "<username>"
You can choose to skip Ansible from managing subscription information by passing -e rhsm_manage=false. Be sure that the machine is subscribed to ansible-2.9-for-rhel-8-x86_64-rpms along with the default RHEL8 repositories.
Provision
Execute the following command in order to provision the machine:
ansible-playbook -i inventory/ playbooks/image_builder.yaml
Once provisioning is complete, a HTTPD container that exposes the RFE image and kickstart file on port 8000.
Edge Nodes
Since the above automation exposes the kickstart file and the edge image, boot the RHEL edge instance and add the kickstart arguments as follows:
inst.ks=http://<image_builder_node>:8000/kickstart.ks
Edge Automation
The key attribute of this architecture is that edge instances configure themselves by executing Ansible automation. This automation lives on a in the ansible-edge branch of this repository. A timer systemd service is configured to execute the automation on a regular basis.
