Fleet vs Hadolint: What are the differences?
Fleet: Container management and deployment for your cluster. Fleet is a low-level cluster engine that feels like a distributed init system. With fleet, you can treat your CoreOS cluster as if it shared a single init system; Hadolint: A Static Analysis Tool for Dockerfiles in Haskell. A smarter Dockerfile linter that helps you build best practice Docker images. The linter is parsing the Dockerfile into an AST and performs rules on top of the AST. It is standing on the shoulders of Shellcheck to lint the Bash code inside RUN instructions.
Fleet and Hadolint belong to "Container Tools" category of the tech stack.
Fleet and Hadolint are both open source tools. It seems that Fleet with 2.45K GitHub stars and 309 forks on GitHub has more adoption than Hadolint with 2.28K GitHub stars and 99 GitHub forks.
