We're pleased to introduce a new Red Hat Access Labs application called Linter for Dockerfile.
The Docker project provides the means of packaging applications in lightweight containers and has quickly become one of the premier projects for containerization. Docker containers offer several advantages over traditional virtual machines such as smaller disk space, less memory, and and increased performance.
The Linter for Dockerfile lab application allows you to check basic dockerfile syntax and also allows you to check that a dockerfile follows best practices according to a selected profile. You can create dockerfiles with the application's editor and validate syntax or you can load existing dockerfiles from URLs or your local disk. The application will validate the syntax of your dockerfile and ensure that it is consistent with good practices.
