10 Docker tips to make the open source container platform work for you

With the Docker platform, developers and more can easily build and deploy containerized apps. Here are 10 tips for working with Docker.

Docker remains the center of the container ecosystems, an open source utility that automates the deployment and management of programs inside containers.

"The widespread adoption of containers has changed the orthodoxy of IT—administrators do not need to run multiple virtual machines to create a barrier between applications or users, nor are programmers beholden to languages such as Java, which have their own strategy for process isolation and lifecycle management," wrote TechRepublic contributing writer James Sanders. Docker leads the way in this change, allowing for easier system administration, Sanders added.

Here are 10 TechRepublic articles with Docker tips that will help enterprise users be more productive.
