Hadolint

A smarter Dockerfile linter that helps you build best practice container images.

Vortex does not install Hadolint. Please follow the [ instructions(https://github.com/hadolint/hadolint#install) to install it on your system.

Usage

hadolint .docker/*.dockerfile

To ignore all Hadolint rules within a file, place in the file header:

# hadolint global ignore=DL3003,DL3006,SC1035
FROM ubuntu

To ignore only the current and the next line:

FROM ubuntu

# hadolint ignore=DL3003,SC1035
RUN cd /tmp && echo "hello!"

This tool runs in CI by default and fails the build if there are any violations.

Set VORTEX_CI_HADOLINT_IGNORE_FAILURE environment variable to 1 to ignore failures. The tool will still run and report violations, if any.
