Docker makes setting up development environments and deploying applications easier than ever. However, many of its best features are under-utilized or misunderstood. Features such as multi-stage Dockerfiles, persistent storage volumes, and multi-container application capabilities are mistakenly passed over when the goal is to - “just get something running!” This Docker course addresses these issues and more.
