Docker Infrastructure

Build Status Master

This project provides infrastructure as code to install three docker environments (dev, qa, prod) on bare metal hardware. Each environment is running a virtual machine with docker-compose running inside. All this is installed on bare metal using Debian preseed, ansible, and docker-compose.

Install

To install the stack on a hardware host perform the following steps:

  1. Download a Debian 9 install medium and start it (not in UEFI-Mode to avoid an eror message)
  2. Go to Advanced options
  3. Focus Automated install and press TAB key to edit the boot options
  4. Add to the line that contains the parameters auto=true priority=critical the parameter preseed/url=https://raw.githubusercontent.com/bob5ec/docker-infrastructure/prod/deploy/hardware.preseed
  5. Hit Enter to start the installation

During partitioning you might get asked if you want to force UEFI boot. It is save to say yes.

Development

If you want to try the development version use change step 4 of the installation to

  1. preseed/url=https://raw.githubusercontent.com/bob5ec/docker-infrastructure/dev/deploy/hardware.preseed

We use test-kitchen to run tests that work within docker to test the setup before actual deployment. Sadly creating VMs requires a physical installation to test on.

Release instruction

To release a new version go to deploy/hardware.preseed and deploy/deploy-ansible.sh search for TODO and set the branch to prod
