ansible is a simple configuration management, deployment, task-execution, and multinode orchestration framework. It uses SSH for the communication between the involved systems, no server or client daemons are needed, and no additional software beside Python on client boxes is required.
Installation of ansible
ansible is available in testing. The latest package is broken, sorry.
Create a SSH key
Generate a SSH key for the managed node. It's recommended to use a key which is protected with a password.
There are only minimal requirements for the clients. For every system you want to manage, you need to have the client's SSH key in the
authorized_keys file of the management system and Python.
Install the Python package.
Transfer the SSH key
There are two ways to do it. From a default Alpine installation you can use ssh and cat to do it.
If you are planning to use additional features of SSH.
ssh-copy-id, which is provided by the
openssh-client package, can help you with the key setup.
Add all your remote systems to
/etc/ansible/hosts. For details, please refer to Hosts and Groups in the ansible documentation.
Another test is check all variables.
When writing playbooks for Alpine Linux there are some issues:
- There is basic support for APK by Ansible. But the following will always work
- Same with the OpenRC, the Init System
- If you are going to re-use playbooks from other Linux distribution, please keep in mind that Alpine Linux uses different paths for the binaries.
