Run super-linter outside GitHub Actions

If you want to run super-linter outside GitHub Actions, you need a container runtime engine to run the super-linter container image.

Run super-linter Locally

You can run the container locally with the following configuration options to run your code:

docker run \
  -e LOG_LEVEL=DEBUG \
  -e RUN_LOCAL=true \
  -v /path/to/local/codebase:/tmp/lint \
  --rm \
  ghcr.io/super-linter/super-linter:latest

This example uses the latest container image version. If you're trying to reproduce an issue, or running super-linter as part of your CI pipeline, we recommend that you refer to a specific version instead.

Notes:

• To run against a single file you can use: docker run -e RUN_LOCAL=true -e USE_FIND_ALGORITHM=true -v /path/to/local/codebase/file:/tmp/lint/file ghcr.io/super-linter/super-linter
• You need to pass the RUN_LOCAL option to bypass some of the GitHub Actions checks, as well as the mapping of your local codebase to /tmp/lint.
• If you want to override the /tmp/lint folder, you can set the DEFAULT_WORKSPACE environment variable to point to the folder you'd prefer to scan.
• You can add as many configuration options as needed. Configuration options are documented in the readme.

GitLab

To run Super-linter in your GitLab CI/CD pipeline, You can use the following snippet:

super-linter:
  # More info at https://github.com/super-linter/super-linter
  stage: Super-linter
  # Use a specific Super-linter version instead of latest for more reproducible builds
  image: super-linter/super-linter:latest
  script: ["true"]
  variables:
    RUN_LOCAL: "true"
    DEFAULT_WORKSPACE: $CI_PROJECT_DIR

Note that this is a high-level example that you should customize for your needs.

Run on Codespaces and Visual Studio Code

This repository provides a DevContainer for remote development.

Share Environment variables between environments

To avoid duplication if you run super-linter both locally and in other environements, such as CI, you can define configuration options once, and load them accordingly:

1. Create a configuration file for super-linter super-linter.env. For example:

   VALIDATE_ALL_CODEBASE=true
   

2. Load the super-linter configuration file when running outside GitHub Actions:

   docker run --rm \
       -e RUN_LOCAL=true \
       --env-file ".github/super-linter.env" \
       -v "$(pwd)":/tmp/lint \
       ghcr.io/super-linter/super-linter:latest
   

3. Load the super-linter configuration file when running in GitHub Actions by adding the following step to the GitHub Actions workflow that runs super-linter, after checking out your repository and before running super-linter:

   - name: Load super-linter configuration
     # Use grep inverse matching to exclude eventual comments in the .env file
     # because the GitHub Actions command to set environment variables doesn't
     # support comments.
     # Ref: https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/workflow-commands-for-github-actions#setting-an-environment-variable
     run: grep -v '^#' .github/super-linter.env >> "$GITHUB_ENV"
   

Build the container image and run the test suite locally

To run the build and test process locally, in the top-level super-linter directory, do the following:

1. Create a fine-grained GitHub personal access token. The token only needs to have public/read-only access.

2. Store the generated personal access token in a file in the top-level directory (This file is ignored by Git).

   echo "github_pat_XXXXXX_XXXXXX" > .github-personal-access-token
   

3. Run the build process:

   . ./scripts/build-metadata.sh && make
   

To avoid invalidating the build cache because of changing values of build arguments, you can set build arguments to arbitrary values before running make, instead of sourcing scripts/build-metadata.sh:

BUILD_DATE=2023-12-12T09:32:05Z \
BUILD_REVISION=83c16f63caa9d432df4519efb4c58a56e2190bd6 \
BUILD_VERSION=83c16f63caa9d432df4519efb4c58a56e2190bd6 \
make

Run the test suite against an arbitrary super-linter container image

You can run the test suite against an arbitrary super-linter container image.

Here is an example that runs the test suite against the v5.4.3 container image version.

CONTAINER_IMAGE_ID="ghcr.io/super-linter/super-linter:v5.4.3" \
BUILD_DATE="2023-10-17T17:00:53Z" \
BUILD_REVISION=b0d1acee1f8050d1684a28ddbf8315f81d084fe9 \
BUILD_VERSION=b0d1acee1f8050d1684a28ddbf8315f81d084fe9 \
make docker-pull test

Initialize the BUILD_DATE, BUILD_REVISION, and BUILD_VERSION variables with the values for that specific container image version. You can get these values from the build log for that version.

Get the list of available build targets

To get the list of the available Make targets, run the following command:

make help

Automatically fix formatting and linting issues

To automatically fix linting and formatting issues when supported, run the following command:

make fix-codebase
