Drone CI

Definition

Drone is a container-native continuous integration and delivery platform where every pipeline step runs inside its own Docker container, configured through a simple YAML file.

Overview

Drone's core idea is that CI/CD pipelines should be built entirely out of containers: each step in a `.drone.yml` pipeline file specifies a container image to run, and Drone executes that step inside an isolated container with the repository checked out, rather than running commands directly on a shared build host. This containers-all-the-way-down model makes pipelines portable and reduces the 'works on my machine' problems that can come from build-agent configuration drift. Drone integrates with source control platforms like GitHub, GitLab, and Bitbucket to trigger pipelines on events such as pushes and pull requests, and it supports a plugin marketplace of prebuilt containerized steps (for tasks like publishing a Docker image, deploying to a cloud provider, or sending notifications) that can simply be referenced by image name in the pipeline YAML rather than installed as server plugins. Originally an independent open-source project, Drone was acquired by Harness, which continues to offer it both as a standalone open-source CI system and as part of its broader delivery platform, making it a common lightweight choice for teams that want Docker-native pipelines without the operational overhead of larger CI systems. It is often mentioned alongside Jenkins in this space. It is often mentioned alongside GitLab CI in this space.
