Why not simply watch a YouTube tutorial? Because they often leave out how to automatically get from Dockerfile to the finished container image in the registry. Participants of our Docker training learn how to deal with containers and, above all, which tools make their work easier. By the end of the course, they will be able to create pipelines with GitLab, Jenkins, and other tools to build container images using Docker or alternatives like Buildah and kaniko. Participants build the necessary infrastructure in the course as container services.
