ansible-role-generate-tls-certs/README.md

Generate TLS certificates

Generates self-signed CA, client and server certificates. Runs locally on control machine.

Notes:

• Will not overwrite any files in output cert dir
• Will not copy the files to the remote servers if the local files are unchanged

Requirements

• For server certificates, must specify Ansible inventory file; FQDN must also be set as hostname in inventory file

Role Variables

See defaults/main.yml

Dependencies

Install dependencies via

$ ansible-galaxy collection install community.crypto

Example Playbook

The provided example playbook.yml targets two hosts (take a look at the Vagrantfile).

All the cryptographic relevant operations are performed on the host machine and the resulting relevant files are copyed to the remote target machine.

If you want to tinker, you can use vagrant with the provided Vagrantfile. It assumes vagrant-libvirt is installed (along with libvirt, of course).

Run it like this:

$ vagrant up --provider=libvirt --provision
