Docker Image for vimeo/psalm

This repository contains everything to build a simple Docker image to run Psalm. The image will also include a few Psalm plugins.

The image is built for the amd64 and arm64 platforms. A GitHub Actions workflow is used to build the image weekly, so the PHP version used should be up-to-date and new Psalm versions should show up automatically.

Running the Published Image

The resulting image is published at https://ghcr.io/webfactory/psalm.

To use it: docker run -it --rm --init -v $(pwd):/app ghcr.io/webfactory/psalm, possibly followed by psalm arguments and options.

If you want to use psalm-plugin to list, enable or otherwise deal with plugins, use:

docker run -it --rm --init -v $(pwd):/app --entrypoint=psalm-plugin ghcr.io/webfactory/psalm, possibly followed by psalm-plugin arguments and options.

Using a Cache for Psalm

If you want to use Psalm's caching feature to speed up analysis, mount a directory or Docker volume at /cache.

For example, run docker run -it --rm --init -v $(pwd):/app -v $HOME/.cache:/cache ghcr.io/webfactory/psalm ...

Building the Image yourself

Review and/or tweak the Dockerfile as necessary.

Then, run docker build -t psalm ..

To use your own image, use psalm instead of ghcr.io/webfactory/psalm in the commands from the previous section.
