How do I correctly move a git submodule?

How can we automate Ubuntu virtual machines for release engineering? (+ Azure cloud, Git, WordPress, Nginx)

• We'd like some ideas on how to automatically configure Ubuntu virtual machines as staging servers for our application, test out the staging code, and then script deployments to the production server (rather than a person installing everything on the staging server via ssh, copying files over, hand-editing configurations, etc.) We can move to AWS if need be but we're okay on Azure for now --- we basically get an Ubuntu VM with SSH access on Azure, so it shouldn't be too different from others ways of configuring linux-based servers. What we want a script to do is basically: Go "in" to the fresh virtual machine via SSH Setup nginx, MariaDB, php, other apt-get installs Deploy a copy of our wordpress code from a Git repository Import a sample staging database into MariaDB with wordpress config info and other information Use the cloudflare API to setup a DNS hostname for the server (optional, can do this manually if needed) Let the person testing the new code poke around Then if it works fine we want to automate pushing the new code in Git to our production server without manually editing wordpress config files and so forth. But that's a bit separate from the question of setting up the staging environment through a script The tools I've come across so far are these Chef Puppet Vagrant Salt Stack Ansible Juju Before diving right into them I was wondering if someone has a 10,000ft view of what is applicable to our needs.

  I've also come across this problem. If you don't need hardware accelerated 3D graphics( or OpenCL, CUDA, etc.) then Vagrant is probably best.
