gitlab ci docker tutorial


GitLab CI/CD in conjunction with GitLab Runner can use Docker Engine to test and build any application. In this tutorial, we are going to the docker socket way.
Use the runner in shell mode Use the runner in privileged mode (gitlab runner user in docker group) Use docker mode and give access to the docker socket.

Docker is an open-source project that allows you to use predefined images to run applications in independent “containers” that are run within a single Linux instance. GitLab and the Runners communicate through an API, so the only requirement is that the Runner’s machine has network access to the GitLab server. Through integrations with many popular version control services, you can use it to build, test, and deliver software automatically whenever your code is updated. If you want to use Docker-in-Docker mode, you always have to use privileged = true in your Docker containers..

In this tutorial we will Setup a Server with gitlab-runner and Docker on Ubuntu and then Setup a Basic Pipeline to utilise your Gitlab Runner. The above command will register a new Runner to use the special docker:19.03.11 image, which is provided by Docker.Notice that it’s using the privileged mode to start the build and service containers. GitLab Community Edition is a self-hosted software suite that provides Git repository hosting, project tracking, CI/CD services, and a Docker image registry, among other features. Drone is a continuous integration and delivery platform written in Go.

Access to your gitlab runner instance and setup the runner with the following command:
In this tutorial we will use GitLab’s continuous integration service to build Docker images from an example Node.js app. Building and Deploying Docker Containers Using GitLab CI Pipelines Learn how to set up a GitLab CI pipeline to automate the building and deployment of Docker containers, saving you time and effort. Using Docker images. GitLab offers a continuous integration service. In Gitlab, you have Shared Runners and you have the ability to run your Own Runners, which is used to run your jobs and send the results back to GitLab. How To Set Up Continuous Integration Pipelines with Drone on Ubuntu 16.04. by The goal of this tutorial is to give a high-level introduction of GitLab CI/CD that helps people get started in 30 minutes without having to read all of GitLab‘s documentation.

For each commit or push to trigger your CI pipeline, you must: ... a Docker container or even a cluster of containers.
