I have constructed a HA web cluster in LXD with each major service run within its own container. I.e, 2 x Nginx servers in a container each, 2 x MySQL etc.

I would like to add a management container that I can ssh to, issue commands, for example, service nginx restart and have the command redirected to the appropriate container, the Nginx servers in this case.

The closest thing I have found is OpenShift but given that I don't want to create a full blown PaaS I would prefer to find something more lightweight.

Is what I want to achieve possible?

    You need something that can handle orchestration. Ansible is great for this task, and can also take care of configuration management and deployment for you as well if desired. – EEAA Dec 04 '15 at 16:30
  • As far as I can tell, Ansible's cheapest package is $5000/year. This is something that will probably never scale past 10 virtual nodes and 2 physical servers so would ideally like a much less expensive solution. – minus8 Dec 04 '15 at 17:06

    No, no. That's their "Ansible Tower" hosted service. Their core configuration management/orchestration software is very much free: https://github.com/ansible/ansible – EEAA Dec 04 '15 at 17:07
