Vagrantfile for RHEL 8

Vagrantfile to spin up a RHEL 8 VM and register with RHN via subscription-manager. It will install the environment for running ansible playbooks to build the red hat ansible workshop on AWS.

Ansible Workshop build out on AWS

ansible-playbook 1_provision.yml

NOTE: If 1_provision.yml playbook has errors you will need to start over after running

ansible-playbook 3_unregister.yml -e NOSSH=true

ansible-playbook 2_load.yml

NOTE: Playbook 2_load.yml will hang twice while doing the subscription manager tasks. After each time it hangs just run the playbook again.

To test workshop

copy the test-workshop.yml file onto the admin server and run

ansible nodes -m shell -a 'rpm -qa | grep docker'
ansible nodes -m shell -a 'rpm -qa | grep podman'
ansible nodes -m shell -a 'docker images redhatgov/alpine' -b 
ansible nodes -m shell -a 'docker images redhatgov/fedora' -b
ansible nodes -m shell -a 'podman images redhatgov/alpine' -b 
ansible nodes -m shell -a 'podman images redhatgov/fedora' -b

To remove the workshop environment from AWS

ansible-playbook 3_unregister.yml

NOTE: If any errors while unregistering run again with environment variable

ansible-playbook 3_unregister.yml -e NOSSH=true

Notes

Using the current latest versions of Vagrant and VirtualBox on MacOS, the version of VirtualBox Guest Additions is newer than the version packaged in roboxes/rhel8. Vagrant will try and update this before the VM has been registered with RHN so all calls to yum install fail. For this reason config.vbguest.auto_update = false is configured.
