Package Install - Universal Docker mod

Using this mod you can install any OS or Python packages during startup by providing them through the environment variables INSTALL_PACKAGES and INSTALL_PIP_PACKAGES. These are then passed into the installation commands as such: apt-get install -y --no-install-recommends ... in Ubuntu and apk add --no-cache ... in Alpine based images for OS packages and pip install ... for python packages.

To enable, in docker container arguments, set an environment variable DOCKER_MODS=linuxserver/mods:universal-package-install and env vars INSTALL_PACKAGES and/or INSTALL_PIP_PACKAGES

If adding multiple mods, enter them in an array separated by |, such as DOCKER_MODS=linuxserver/mods:universal-package-install|linuxserver/mods:universal-stdout-logs.

Similarly, for installing multiple packages separate them by |. E.g., to install rsync, git and nginx OS packages and apprise python package, add the following lines to your docker compose service:

- DOCKER_MODS=linuxserver/mods:universal-package-install
- INSTALL_PACKAGES=rsync|git|nginx
- INSTALL_PIP_PACKAGES=apprise

Notes:

• Package names entered should match the names in the relevant distro repo: https://pkgs.alpinelinux.org/packages or https://packages.ubuntu.com/
• Setting the env var INSTALL_PIP_PACKAGES will result in automatic install of the python3-dev and python3-pip OS packages, updating of pip to the latest version and installation of the latest setuptools and wheel packages to set up the necessary environment.
• Any other OS dependency such as make or git, which may be needed by the pip install process, should be manually added to INSTALL_PACKAGES.
• The OS packages defined will be installed first, followed by the pip packages.
• Pip will also use the relevant linuxserver wheel repo as an additional index to pull prebuilt wheels for common packages (ie. https://wheel-index.linuxserver.io/ubuntu/ and https://wheel-index.linuxserver.io/alpine-3.16/).
