Simple static Composer repository generator.

Build Status codecov

Run from source

  • Install satis: composer create-project composer/satis:dev-master
  • Build a repository: php bin/satis build <configuration-file> <output-dir>

Read the more detailed instructions in the documentation.

Run as Docker container

Pull the image:

docker pull composer/satis

Run the image (with Composer cache from host):

docker run --rm --init -it \
  -u $(id -u):$(id -g) \
  -v $(pwd)/build:/build \
  -v "${COMPOSER_HOME:-$HOME/.composer}:/composer" \

If you want to run the image without implicitly running Satis, you have to override the entrypoint specified in the Dockerfile:

--entrypoint /bin/sh


If you choose to archive packages as part of your build, over time you can be left with useless files. With the purge command, you can delete these files.

php bin/satis purge <configuration-file> <output-dir>

Note: don't do this unless you are certain your projects no longer reference any of these archives in their composer.lock files.


Updating Satis is as simple as running git pull && composer install in the Satis directory.

If you are running Satis as a Docker container, simply pull the latest image.
