Hadolint vs Spread: What are the differences?
Developers describe Hadolint as "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. On the other hand, Spread is detailed as "*CLI to deploy Docker to Kubernetes in one command *". Redspread is a command line tool that builds and deploys a Docker project to a Kubernetes cluster in one command.
Hadolint and Spread can be primarily classified as "Container" tools.
Hadolint and Spread are both open source tools. It seems that Hadolint with 2.28K GitHub stars and 99 forks on GitHub has more adoption than Spread with 1.86K GitHub stars and 84 GitHub forks.
