Currently I have 3 linode servers:
1: Cache server (Ubuntu, varnish)
2: App server (Ubuntu, nginx, rabbitmq-server, python, php5-fpm, memcached)
3: DB server (Ubuntu, postgresql + pg_bouncer)
On my app-server I have multiple sites (topdomains). Each site is inside a virtualenviroment created with virtualenvwrapper. Some sites are big with a lot of traffic, and some site are small with little traffic.
A typical site consist of python (django), celery (beat, flower) and gunicorn.
My current development pattern now is working inside a staging environment on the app-server and committing changes to git. Then change environment to the production environment and doing a git pull
, and a ./manage.py migrate
and restarting the process doing sudo supervisorctl restart sitename:
, but this takes time! There must be a simpler method!
Therefore it seems like docker could help simplify everything, but I can't decide the best approach for how I could manage all my sites and containers inside each site.
I have looked at http://panamax.io and https://github.com/progrium/dokku, but not sure if one of them fit my needs.
Ideally I would run a development version of each site on my local machine (emulating cache-server, app-server and db-server), do code changes there and test them. When I would see the changes worked, I would execute a command that would do all the heavy lifting and send the changes to the linode servers (I would think mostly the app-server), do all the migration and restarting the project on the server.
Could anyone point me in the right direction as how to achieve this?
