* Add restart for weave service unit
* Reuse docker_bin_dir everythere
* Limit systemd managed docker containers by CPU/RAM. Do not configure native
  systemd limits due to the lack of consensus in the kernel community
  requires out-of-tree kernel patches.

@@ -20,5 +20,12 @@ For a large scaled deployments, consider the following configuration changes:
``dns_cpu_requests``, ``dns_memory_limit``, ``dns_memory_requests``.
Please note that limits must always be greater than or equal to requests.
* Tune CPU/memory limits and requests. Those are located in roles' defaults
and named like ``foo_memory_limit``, ``foo_memory_requests`` and
``foo_cpu_limit``, ``foo_cpu_requests``. Note that 'Mi' memory units for K8s
will be submitted as 'M', if applied for ``docker run``, and cpu K8s units will
end up with the 'm' skipped for docker as well. This is required as docker does not
understand k8s units well.
For example, when deploying 200 nodes, you may want to run ansible with
``--forks=50``, ``--timeout=600`` and define the ``retry_stagger: 60``.
