Dockerfile Linter

What is the Dockerfile Linter?

The Dockerfile Linter analyzes Dockerfiles and detects common mistakes, unsafe patterns, missing flags, inefficient layers, and best‑practice violations. It checks for issues such as the use of ':latest', incorrect apt‑get usage, missing flags, unnecessary COPY operations, and unsafe curl commands. This makes it ideal for container developers, DevOps engineers, CI/CD pipelines, and anyone who wants to optimize Docker images. The entire linting process runs client‑side, ensuring full privacy and fast performance. A simple and effective way to validate Dockerfiles before building or deploying containers.
