Drone CI as Docker Stack (in Swarm mode)

Example setup of Drone CI in a Docker Stack using Swarm mode.

Usage

Simplest usage is by running the deploy.sh script after configuring the agent and server settings:

git clone https://github.com/gesellix/drone-stack
cd drone-stack
vi .server-env
vi .agent-env
./deploy.sh

The script prepares a Docker volume for the Drone server's database and initializes your Docker engine in Swarm mode. Via docker stack deploy the complete stack with server and agents will be deployed to your Docker engine.

The Drone CLI is also available as Docker image and can be used like this:

docker run --rm -it -e DRONE_SERVER=http://example.com:8000 -e DRONE_TOKEN=foo.bar.baz drone/cli info

Security notice about credentials/tokens

Beware that your secrets are saved in .agent-env and .server-env. After drone/#2223 being implemented, both files (or parts of them) should be converted to Docker secrets.

GitHub integration

For the GitHub integration you'll need to create an OAuth App at https://github.com/settings/developers. The Homepage URL should point to your Drone server (e.g. http://example.com:8000), the Authorization callback URL should append /authorize (e.g. http://example.com:8000/authorize).

Due to the initial OAuth flow, the Drone CI server needs to be publicly available at example.com:8000.
