Minimal devcontainer definitions aimed at working with vscode flatpak and podman-remote

Prerequisites

• Visual Studio Code flatpak needs the com.visualstudio.code.tool.podman extension.
• Set podman-remote as the Docker executable in Visual Studio Code. In the settings.json add:

  "dev.containers.dockerPath": "/app/tools/podman/bin/podman-remote"

• Allow vscode to access xdg-run/podman in filesystem permissions.
• The podman.socket service needs to be running at the user level.
  • Start it with:

    systemctl --user start podman.socket

  • Or make it persisten between reboots:

    systemctl --user enable --now podman.socket

• SELinux's enforcing policy may lead to errors accessing files in the container.
