Container images for CI

During the development of my websites, programs and scripts, I frequently use multiple tools that provide syntax/linting checking or automatic code testing. To be able to use these in an automatic CI/CD environment I have made some simple container images for most of them, with sometimes even a custom wrapper script to simplify it.

Some reusable stable images are listed below:

• Yamllint (YAML)
• Jsonlint (JSON)
• ESLint (Javascript/Typescript)
• Flake8 (Python)
• Pylint (Python)
• Pytest (Python)
• Shellcheck (CSS/SCSS)
• Stylelint (Bash)
• PSScriptAnalyzer (Powershell)

Yamllint (YAML)

Yamllint is a syntax checker for YAML configuration files.

Configuration

I personally use .yamllint.yaml but some other formats are also supported.

Usage

docker run --rm -v /local/path:/code hdcore/docker-yamllint:1 yamllint

Image source

Jsonlint (JSON)

@prantlf/jsonlint is a syntax checker for JSON files. This image is based on a fork of the orginal Jsonlint but with much more options and possibilities.

Configuration

I personally use .jsonlintrc.yaml but some other formats are also supported.

Usage

docker run --rm -v /local/path:/code hdcore/docker-jsonlint:1 jsonlint.sh

ESLint (Javascript)

ESLint is a static analyzer for javascript code.

Configuration

I personally use .eslintrc.cjs but some other formats are also supported.

Usage

docker run --rm -v /local/path:/code hdcore/docker-eslint:8 eslint.sh .

Flake8 & Pytest (Python)

Flake8 is a static code style checker for python code.

Pytest is a testing framework for python code.

Configuration

I personally use .flake8 as the configuration file for Flake8 and no file for Pytest

Usage

docker run --rm -v /local/path:/code hdcore/docker-flake8:7 flake8
docker run --rm -v /local/path:/code hdcore/docker-flake8:7 pytest \<subfolder\>

Pylint (Python)

Pylint is a static code style checker for python code.

Configuration

I personally use .pylintrc as the configuration file.

Usage

docker run --rm -v /local/path:/code hdcore/docker-pylint:3 pylint

• https://gitlab.com/hdcore-docker/docker-pylint

PSScriptAnalyzer (Powershell)

PSScriptAnalyzer is a static code style checker for python code.

Configuration

I personally use PSScriptAnalyzerSettings.psd1 as the configuration file.

Usage

docker run --rm -v /local/path:/code hdcore/docker-psscriptanalyzer:1 Invoke-ScriptAnalyzer.sh -Path <directory> -Recurse

Stylelint (CSS/SCSS)

Stylelint is a static code style checker for stylesheet files.

Configuration

I personally use stylelint.config.mjs as the configuration file.

Usage

docker run --rm -v /local/path:/code hdcore/docker-stylelint:16 stylelint.sh [<extra-shellcheck-arguments>]

• https://gitlab.com/hdcore-docker/docker-shellcheck

Shellcheck (Bash)

PSScriptAnalyzer is a static code style checker for python code.

Configuration

This has to be done inline the files

Usage

docker run --rm -v /local/path:/code hdcore/docker-shellcheck:stable shellcheck-dir.sh <directory> [<extra-shellcheck-arguments>]
