Hadolint vs kaniko: 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, kaniko is detailed as "Build container images in Kubernetes". A tool to build container images from a Dockerfile, inside a container or Kubernetes cluster kaniko doesn't depend on a Docker daemon and executes each command within a Dockerfile completely in userspace. This enables building container images in environments that can't easily or securely run a Docker daemon, such as a standard Kubernetes cluster..
Hadolint and kaniko can be categorized as "Container" tools.
Hadolint and kaniko are both open source tools. It seems that kaniko with 3.96K GitHub stars and 311 forks on GitHub has more adoption than Hadolint with 2.28K GitHub stars and 99 GitHub forks.
