Basically what I'm trying to do is to create a simple multi-node env with varnish+nginx+mariadb+memcached. By now I've managed to launch the environment and attach git project to it. The problem is that we work with php and symfony2, which requires composer to be executed at least once in order to properly deploy the application.
Outside of jelastic we use Jenkins + Ant (but we don't scale horizontally in automatic on the projects where this setup is used, so it's not a problem to add node manually).
So the question is: How can I run composer or ant with build.xml on each deploy?
I see that Java environments have a build server option, is there something like this for php environments?
