Setting up the DC/OS Vagrant development environment

Unfortunately there is no suitable setup with just Mesos, so we're going to have to roll out the official DC/OS development environment which is based on Vagrant and VirtualBox. Do not try this with less than 32GB of RAM.

DC/OS Vagrant quick start

  1. Install Vagrant and VirtualBox.
  2. Install vagrant-hostmanager plugin.
$ vagrant plugin install vagrant-hostmanager
  1. Clone, configure, deploy. This will take a while.
$ git clone https://github.com/dcos/dcos-vagrant
$ cd dcos-vagrant
$ cp <path/to/o²control/hacking>/VagrantConfig.yaml .
$ vagrant up

See the DC/OS Vagrant README for more information.

Setting up O² software

This bit really depends on what we want to run. As a minimum, the executor and occ plugin must be installed on the DC/OS cluster, and the easiest way to do this is from aliBuild-generated RPMs alisw-Control including alisw-Control-OCCPlugin.

fpctl can help with this. Install it as instructed with fpctl setup, then copy into the fpctl configuration directory the inventory file for DC/OS Vagrant.

$ cp <path/to/o²control/hacking>/inventory ~/.config/fpctl/

Then we run fpctl to install O² software and configuration. This will also set some Mesos agent attributes which can be useful for matching an O² role to the correct machine. Ansible will spit out some errors, which are generally safe to ignore in this case.

$ fpctl deploy -e "ignore_errors=yes"

If fpctl prompts for it, the password for the vagrant user on the DC/OS VMs is vagrant.

Continue with running O² Control.
