Runner is installed on: Executor is: Container is running: Windows docker-windows Windows Windows docker Linux Linux docker Linux

The Docker executor supports the following configurations.įor known issues and additional requirements of Windows configurations, see Use Windows containers.

Post-job: Create cache, upload artifacts to GitLab.

Job: Runs your build in the Docker image you configure for the runner.

Prepare: Creates and starts the services.

The Docker executor divides the job into several steps: The special Docker image, see the GitLab Runner repository. The Docker executor uses a special Docker image based on Alpine Linux thatĬontains the tools to run the prepare, pre-job, and post-job steps.

The configurations you define in config.toml.

To connect to Docker Engine, the executor uses: To run each job in a separate and isolated container.

Use the same image to test commands locally without the requirement of running a job in the CI server.

Maintain the same build environment for each job.

GitLab Runner uses the Docker executor to run jobs on Docker images.
