Flatpak is a technology for building and distributing applications that will work universally on all Linux distributons, it is similar Snap,

Setup / Installation

From: https://flatpak.org/setup/Alpine/

To install Flatpak you will need to enable the Community repository, See: Post Installation - Repositories

To install Flatpak run:

apk add flatpak

Next you need to add a repository, for this guide we will use the recommended repository, Flathub

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Now reboot to complete setup

Flatpak - available runtimes

These are all hosted on Flathub.org.

Fixing Audio Issues

If you have a minimal setup and don't have access to audio devices you will need to set the XDG_RUNTIME_DIR variable. Save the following script in /etc/profile.d/xdg_runtime_dir.sh and re-login to have it set up properly.

if test -z "${XDG_RUNTIME_DIR}"; then
  export XDG_RUNTIME_DIR=/tmp/$(id -u)
fi

When you launch a Flatpak you will need to start pulseaudio as well:

pulseaudio --start && flatpak run com.example.Example
