 By default, Composer runs as root inside the container. This can lead to permission issues on your host filesystem. You can work around this by running the container with a different user:

 When combining the use of private repositories with running Composer as another user, you might run into non-existent user errors (thrown by ssh). To work around this, simply mount the host passwd and group files (read-only) into the container:
