Ignoring

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

# dclint disable
version: '3.8'
services:
  app:
    image: ubuntu

Ignoring fail in continuous integration pipeline

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

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