Building Hydrogen AppImage in Docker

Installation instructions based upon those found here.

AppImage packaging instructions here

Build the image

podman build -t hydrogen-builder .

Build Hydrogen

podman run --privileged -v "$(pwd)/out:/out" hydrogen-build:latest

After the build has complete, the AppImage file will be found in /out

Testing the image

Running the image in an interactive session allows for easier debugging of the build process.

podman run --privileged -it hydrogen-build:latest bash

Running the build script at the root of the container filesystem initiates the build.

./build.sh

You may attach to an exited container by using podman start.

podman start --interactive --attach <containerid>

Rebuild the AppImage using linuxdeploy.

cd hydrogen/build
/linuxdeploy-x86_64.AppImage --appdir AppDir -e Hydrogen --output appimage
