## Basic usage

1. Set up Docker Swarm and [`abra`]
2. Deploy [`coop-cloud/traefik`]
3. `abra app new drone --secrets` (optionally with `--pass` if you'd like
   to save secrets in `pass`)
4. `abra app config YOURAPPDOMAIN` - be sure to change `DOMAIN` to something that resolves to
   your Docker swarm box
5. `abra app deploy YOURAPPDOMAIN`
6. Open the configured domain in your browser to finish set-up

## Setup with Gitea

follow this guide: https://docs.drone.io/server/provider/gitea/

then you'll also need to setup drone-docker-runner (`abra app new drone-docker-runner`). More info at https://docs.drone.io/runner/docker/installation/linux/.


## Setting up a server for auto-deployment

For Drone to be able to deploy to a server, you need:

- A drone user on the server, added to the `docker` group
- An SSH key, added as a secret in Drone, and added to `/home/drone/.ssh/authorized_keys on the server`

1. Add a `drone` user on `example.zone`, the server which you’re hosting the site on.

	a. `sudo adduser drone`
	
	b. create an SSH key for the user using `ssh-keygen` , e.g. `sudo -u drone ssh-keygen`
	
	c. copy the contents of the public side of the new key to `/home/drone/.ssh/authorized_keys`
	
	d. run `chmod go-rwx /home/drone/.ssh`
	
	e. add `drone` to `AllowUsers` in `/etc/ssh/sshd_confand` restart SSH, `sudo service sshd restart`
	
2. Give the drone user access to the `docker` group; `sudo usermod -aG docker drone`

3. Generate a new SSH key and insert it as a Drone “orgsecret”

	a. Log into Drone as `admin`, then either:
	
	b. Add the “orgsecret” using the [Drone CLI](https://docs.drone.io/cli/install/):
	
		i. Go to the “account” page https://drone.autonomic.zone/account
		
		ii. Copy/paste the “Example CLI usage” into a terminal (you might want to add to `~/.bashrc` to make this easier  next time)
		
		iii. Run `drone orgsecret add [org you're adding the org secret to] [domain name] @drone_ssh_[example.zone]`
		
	c. Add the “orgsecret” using the Drone web interface:
	
		i. Find the repository page, or the page for another repository in the same organisation, in Drone
		
		ii. On the “Settings” tab, under “Organization” on the left, click “Secrets”, then create a new secret and paste in the private key value
