Mission control for Docker

gattai is a client for Docker with the orchestration workflow in mind. It is based on docker/cli so its commands are fully compatible with docker. Basically, gattai can be a drop-in replacement for docker client.

In addition, gattai includes libmachine for machine provisioning, codes from swarm for built-in discovery management. It's planned to include libcompose for service composition in future releases.

You can setup a Docker cluster with gattai in just 4 steps.

• $ gattai init will initialize a Gattai repository to store workflow-related files.
• Open and edit provision.yml as follows:

---
machines:
  ocean:
    driver: digitalocean
    instances: 2
    options:
      digitalocean-access-token: $DIGITALOCEAN_ACCESS_TOKEN
      digitalocean-region: sgp1
      engine-install-url: "https://experimental.docker.com"

  master:
    from: ocean

• $ gattai provision will read provision.yml and prepare 3 machines, ocean-1, ocean-2 and master, for you.
• $ gattai cluster -m master ocean will form a Docker cluster using swarm. The master machine will be your swarm manager and set active.

After the cluster command, you can now use gattai docker commands to place containers on your cluster.
