Ansible
Dive Into Ansible LabThe Dive Into Ansible lab is equipped with an Ansible Control Host (ubuntu-c) and six virtual machines, ubuntu1 to ubuntu3 and centos1 to centos3. All instances can be accessed via a web terminal.
Use the button to launch a cloudshell instance, preconfigured with the lab. Upon being prompted, you do not need to 'trust' the image. A tutorial with interactive steps will appear on the right hand side.
The lab can also be used locally on Mac OS X, Windows and Linux using Docker. Please see https://github.com/spurin/diveintoansible-lab
