Setting up a new Docker swarm box

Create and provision a new VPS with Docker installed.

The easiest way of doing this is using actions/newhetzner.yml in our infrastructure repository.

Make sure you have infrastructure cloned and set up according to the instructions, then run ansible-playbook actions/newhetzner.yml and answer the questions.

  1. Add the server to your ~/.ssh/config file (you'll at least need to specify Port 222).
  2. Add the suggested entry to inventories/inventory
  3. Create a new servers/<client>/<server>.yml file, based on servers/neuronic/swarm.yml (including the swarm.single-node role)
  4. Run ansible-playbook servers/<client>/<server>.yml to install Docker

The easiest way forwards from here is to install abra and use it to set up remote context and initialise the swarm:

  1. curl -fsSL https://install.abra.autonomic.zone | bash
  2. abra context create swarm.client.tld yourusername 222
  3. abra context init swarm.client.tld
  4. abra context use swarm.client.tld
