DCLint

https://github.com/zavoloklom/docker-compose-linter

A command-line tool for validating and enforcing best practices in Docker Compose files.

Vortex does not install DCLint. Please follow the instructions to install it on your system.

DCLint is selected by default during installation. Deselecting it in the Development tools question removes the .dclintrc configuration file and the continuous integration step from every supported provider.

Usage​

dclint docker-compose.yml

Ignoring​

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

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

To ignore only specific rules:

version: '3.8'
services:
  # dclint disable-next-line no-version-field
  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.
