The image builder is based on the following technologies:
- Ansible, for recipe declaration
- Ansible Galaxy, for third party resources
- Vagrant, for local testing
- Docker, for CI testing
All recipes are written to work on Red Hat Enterprise Linux, also know as CentOs.
All interactions are done with the make command. You can just run make or make help to list all the available commands.
You can test if you have the correct tools installed by running make are-requirements-ok.
To test all the playbooks, simply run make test. To test a specific one, run make test-playbook PLAYBOOK=< playbook-name >.
Local builds uses Vagrant to run. The playbook is copied & modified on the fly to match the local environment, so no remote host will be used.
You can test more than one playbook at a time, it'll launch a new VM for each playbook without any conflict - other than network ports.
When writing a new playbook / role, you can test it locally by running the following command: make debug-run PLAYBOOK=< playbook-name >.
It'll spin up a vagrant VM & run ansible on it.
Once the build is finished, you can shh on it by running this command: make debug-run-ssh PLAYBOOK=< playbook-name >.
You must delete unused VM manually by running make debug-run-destroy PLAYBOOK=< playbook-name >.
Run make run PLAYBOOK=< playbook-name > and ensure inventory/inventory.ini is properly set.
