dflemstr/drone-dind repository overview

⁠Drone base image for Docker-in-Docker

This repository builds a Docker image to be used with Drone CI⁠ that starts an isolated Docker daemon for your builds. This enables the building of Docker-based projects in Drone.

⁠Usage

Given a repository containing a Dockerfile, put the following in your Drone configuration file .drone.yml:

image: dflemstr/drone-dind
script:
  - docker build -t me/myservice .
  - docker push me/myservice:latest

Add this repository to your Drone instance, making sure that you use privileged containers (since Docker-in-Docker requires that). You can now successfully build Docker-based projects on top of Drone.

⁠How it works

The image contains two scripts, start-docker and stop-docker, that will start and stop the inner Docker daemon, respectively. There is also a file called docker-helper.sh that gets sourced by Drone on every build, that makes sure that start-docker is ran before, and stop-docker is ran after the build.
