# stack-ssh-deploy

Deploy swarm stacks against a SSH based remote docker daemon context.

This is meant to be used as a [Drone plugin](http://plugins.drone.io/).

## Settings

### Required (no default)

- **deploy_key**: SSH private key part for ssh public key authentication
- **stack**: Name of the stack to be deployed

### Required (If Private Repo)

- **image**: Name and Tag of image since private image's are not pulled automatically by docker stack deploy

### Optional (with defaults)

- **compose** (default: `compose.yml`): compose file to use for deploying
- **host** (default: `swarm.autonomic.zone`): Host to deploy to (don't include `ssh://`)
- **port** (default: `222`): SSH port to connect to
- **user** (default: `drone`): System user to connect via SSH with
- **networks** (default:): Try and auto-create these networks first
- **rm**: (default: `false`): Remove the stack before deploying it
- **reg_user**: Registry user if publishing from a private repository
- **reg_pass**: Registry password if publishing from a private repository
- **reg_url**: Registry URL

### Dangerous options, unwise outside CI

- **generate_secrets** (default: `false`): randomly set all `secrets:` found in the
  compose file -- you won't be able to retrieve them afterwards, so you almost
  certainly don't want this for real deployments.
- **purge** (default: `false`): runs aggresive cleaning up measure to wipe
  deployment afterwards

## Example

```yaml
---
kind: pipeline
name: deploy to swarm
steps:
  - name: stack deploy
    image: decentral1se/stack-ssh-deploy:latest
    settings:
      stack: mystack
      deploy_key:
        from_secret: drone_deploy_key
      networks:
        - proxy
        - mail
      environment:
        DOMAIN: test.example.com
```

## Publishing

The version can be bumped in the [.drone.yml](./.drone.yml) file. We're sticking with `latest` as we iterate on the code right now.

If you push a commit to master, the [Drone config](./.drone.yml) will publish to [Docker Hub](https://hub.docker.com/r/decentral1se/stack-ssh-deploy).
