After having multiple people report issues with retrieving
SSL certificates, we've finally discovered the culprit to be
Ansible 2.5.1 (default and latest version on Ubuntu 18.04 LTS).
As silly as it is, certain distributions ("LTS" even) are 13 bugfix
versions of Ansible behind.
From now on, we try to auto-detect buggy Ansible versions and tell the
user. We also provide some tips for how to upgrade Ansible or
run it from inside a Docker container.
My testing shows that Ansible 2.4.0 and 2.4.6 are OK.
All other intermediate 2.4.x versions haven't been tested, but we
trust they're OK too.
From the 2.5.x releases, only 2.5.0 and 2.5.1 seem to be affected.
Ansible 2.5.2 corrects the problem with `include_tasks` + `with_items`.

Running this playbook
This playbook is meant to be run using Ansible.
Supported Ansible versions
Generally, Ansible 2.4 or later is required.
If you're on Ansible 2.5.x, then at least Ansible 2.5.2 is required.
Checking your Ansible version
In most cases, you won't need to worry about the Ansible version. The playbook will try to detect it and tell you if you're on an unsupported version.
To manually check which verison of Ansible you're on, run: ansible --version.
If you're on an old version of Ansible, you should upgrade to a newer version.
Upgrading Ansible
Depending on your distribution, you may be able to upgrade Ansible in a few different ways:
-
by using an additional repository (PPA, etc.), which provides newer Ansible versions
-
by removing the Ansible package (
yum remove ansibleorapt-get remove ansible) and installing via pip (pip install ansible).
If using the pip method, do note that the ansible-playbook binary may not be on the $PATH (https://linuxconfig.org/linux-path-environment-variable), but in some more special location like /usr/local/bin/ansible-playbook. You may need to invoke it using the full path.
Note: Both of the above methods are a bad way to run system software such as Ansible. If you find yourself needing to resort to such hacks, please consider reporting a bug to your distribution and/or switching to a sane distribution, which provides up-to-date software.
Using Ansible via Docker
Alternatively, you can run Ansible itself from a Docker container on your computer.
Here's a sample command to get you started (run this from the playbook's directory):
docker run -it --rm \
-w /work \
-v `pwd`:/work \
-v $HOME/.ssh/id_rsa:/root/.ssh/id_rsa:ro \
--entrypoint=/bin/sh \
qmxme/ansible
The above command tries to mount an SSH key ($HOME/.ssh/id_rsa) into the container (at /root/.ssh/id_rsa).
If your SSH key is at a different path (not in $HOME/.ssh/id_rsa), adjust that part.
If you don't use SSH keys for authentication, simply remove that whole line (-v $HOME/.ssh/id_rsa:/root/.ssh/id_rsa:ro).
Once you execute the above command, you'll be dropped into a /work directory inside a Docker container.
The /work directory contains the playbook's code.
You can execute ansible-playbook commands as per normal now.
