flatpak (1) - Linux Manuals

Flatpak can operate in system-wide or per-user mode. The system-wide data (runtimes, applications and configuration) is located in $prefix/var/lib/flatpak/, and the per-user data is in $HOME/.local/share/flatpak/. Below these locations, there is a local repository in the repo/ subdirectory and installed runtimes and applications are in the corresponding runtime/ and app/ subdirectories.

System-wide remotes can be statically preconfigured by dropping flatpakrepo files into /etc/flatpak/remotes.d/.

In addition to the system-wide installation in $prefix/var/lib/flatpak/, which is always considered the default one unless overridden, more system-wide installations can be defined via configuration files in /etc/flatpak/installations.d/, which must define at least the id of the installation and the absolute path to it. Other optional parameters like DisplayName, Priority or StorageType are also supported.

Flatpak uses OSTree to distribute and deploy data. The repositories it uses are OSTree repositories and can be manipulated with the ostree utility. Installed runtimes and applications are OSTree checkouts.

Basic commands for building flatpaks such as build-init, build and build-finish are included in the flatpak utility. For higher-level build support, see the separate flatpak-builder(1) tool.

ENVIRONMENT

Besides standard environment variables such as XDG_DATA_DIRS and XDG_DATA_HOME, flatpak is consulting some of its own.

FLATPAK_USER_DIR

The location of the per-user installation. If this is not set, $XDG_DATA_HOME/flatpak is used.

FLATPAK_SYSTEM_DIR

The location of the default system-wide installation. If this is not set, /var/lib/flatpak is used (unless overridden at build time by --localstatedir or --with-system-install-dir).

FLATPAK_SYSTEM_CACHE_DIR

The location where temporary child repositories will be created during pulls into the system-wide installation. If this is not set, a directory in /var/tmp/ is used. This is useful because it is more likely to be on the same filesystem as the system repository (thus increasing the chances for e.g. reflink copying), and we can avoid filling the user's home directory with temporary data.

FLATPAK_CONFIG_DIR

The location of flatpak site configuration. If this is not set, /etc/flatpak is used (unless overridden at build time by --sysconfdir).
