Build a simple lab using podman and systemd, ready for exercising with Ansible, inspired by @mrjackv ansible-nspawn

• systemd
• podman
• buildah
• python
• ssh-keygen, ssh
• ansible

First run the setup

./setup

This script will generate an ssh-key pair, setup the podlab network and then download a centos:stream9 image and perform the following steps on it:

• add podlab labels
• install userful packages (see Included Pakcages)
• add ansible user
• add ansible ssh key
• allow ansible to sudo without password
• add a student user
• allow root login

then start pods with the boot script, and you can set optionally the ansible gruop to which they will belong.

./boot [group]

You can also use the option -a to attach directly to the new container.

Finally you can run your playbooks like this:

ansible-playbook ./playbooks/example.yml

After you're done excercising, you can stop the lab with the command

./shutdown

You can also use the -c option to delete the image and the network. They will be created again next time tou run the setup script

1. playbooks: A direcotry where you can place you playbooks. podLAB comes with a playbook named example.yml. You can run it with the command ansible-playbook playbooks/example.yml
2. ansible.cfg: The configuration to tell ansible how to connect to podLAB containers
3. boot: Runs a podLAB container (see usage)
4. inventory: Inventory script for Ansible in Python, it will filter out any non-podLAB containers
5. LICENSE: podlab's MIT license
6. podssh: ssh script in podman's unshare net namespace environment, it allows to ssh to any container easily.
7. README.md: This file :)
8. setenv: podLABS configuration
9. setup: Configures the environment for podLAB's usage (see usage)
10. shutdown: Stops all podLAB's containers, and optionally clears images and networks (see usage)
11. ssh_config: The ssh configuration file that allows ansible and manual ssh connection to containers
