You may want to put some effort (not that much) into managing your credentials with Ansible Vault[0] and you can try your playbooks e.g. on a Vagrant Machine[1] before applying them to a real host.

Any tutorial will do for the beginning but you should always notice what version of Ansible you are using (vs. the one used in the tutorial) as features change and also there have been some changes to the syntax to improve readability of your playbooks.

Uses ansible + docker to setup and run a home server. Its feature-set is close to that of a typical FreeNAS setup in a home environment.
