There are two primary ways to incorporate Docker into your CI/CD workflow:
Run your CI/CD jobs in Docker containers.
You can create CI/CD jobs to do things like test, build, or publish an application. These jobs can run in Docker containers.
For example, you can tell GitLab CI/CD to use a Node image that’s hosted on Docker Hub or in the GitLab Container Registry. Your job then runs in a container that’s based on the image. The container has all the Node dependencies you need to build your app.
Use Docker or kaniko to build Docker images.
You can create CI/CD jobs to build Docker images and publish them to a container registry.
