Short Term notes for running the OpenCrowbar in Docker

This is the TL;DR version; the full version is here.

  1. Place the OS install ISOs for OSes you want to deploy on to slaves in $HOME/.cache/opencrowbar/tftpboot/isos. We currently support:
  2. CentOS-6.5-x86_64-bin-DVD1.iso
  3. RHEL6.4-20130130.0-Server-x86_64-DVD1.iso
  4. ubuntu-12.04.4-server-amd64.iso
  5. Prep Environment
  6. Install Docker (do once)
  7. sudo chmod 666 /var/run/docker.sock (to run docker without sudo)
  8. sudo usermod -a -G docker <your-user> (to permanently run Docker without sudo)
  9. To build Sledgehammer:
  10. tools/build_sledgehammer.sh
  11. To run in development mode:
  12. tools/docker-admin centos ./development.sh
  13. To run in production mode:
  14. tools/docker-admin centos ./production.sh admin.cluster.fqdn The first time you run this, it will take awhile as caches a few critical files and extracts the ISOs.
  15. tools/kvm-slave (to launch a KVM-based compute node)

Once Crowbar is bootstrapped (or if anything goes wrong), you will get a shell running inside the container. Exiting the shell will kill Docker.
