flatpak Developer Alexander Larsson alexl@redhat.com flatpak 1 flatpak Build, install and run applications and runtimes flatpak OPTION COMMAND flatpak is a tool for managing applications and the runtimes they use. In the flatpak model, applications can be built and distributed independently from the host system they are used on, and they are isolated from the host system ('sandboxed') to some degree, at runtime. 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 config fragments 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. The following options are understood: -h --help Show help options and exit. -v --verbose Print debug information during command processing. --ostree-verbose Print OSTree debug information during command processing. --version Print version information and exit. --default-arch Print the default arch and exit. --supported-arches Print the supported arches in priority order and exit. --gl-drivers Print the list of active gl drivers and exit. Commands for managing installed applications and runtimes: flatpak-install1 Install an application or a runtime from a remote or bundle. flatpak-update1 Update an installed application or runtime. flatpak-uninstall1 Uninstall an installed application or runtime. flatpak-list1 List installed applications and/or runtimes. flatpak-info1 Show information for an installed application or runtime. Commands for running applications: flatpak-run1 Run an application. flatpak-override1 Override permissions for an application. flatpak-make-current1 Specify the default version to run. flatpak-enter1 Enter the namespace of a running application. Commands for managing file access: flatpak-document-export1 Grant an application access to a specific file. flatpak-document-unexport1 Revoke access to a specific file. flatpak-document-info1 Show information about a specific file. flatpak-document-list1 List exported files. Commands for managing remote repositories: flatpak-remotes1 List all configured remote repositories. flatpak-remote-add1 Add a new remote repository. flatpak-remote-modify1 Modify properties of a configured remote repository. flatpak-remote-delete1 Delete a configured remote repository. flatpak-remote-ls1 List contents of a configured remote repository. Commands for building applications: flatpak-build-init1 Initialize a build directory. flatpak-build1 Run a build command in a build directory. flatpak-build-finish1 Finalizes a build directory for export. flatpak-build-export1 Export a build directory to a repository. flatpak-build-bundle1 Create a bundle file from a build directory. flatpak-build-import-bundle1 Import a file bundle into a local repository. flatpak-build-sign1 Sign an application or runtime after its been exported. flatpak-build-update-repo1 Update the summary file in a repository. flatpak-build-commit-from1 Create a new commit based on an existing ref. 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_CONFIG_DIR The location of flatpak site configuration. If this is not set, /etc/flatpak is used (unless overridden at build time by --sysconfdir). ostree1, ostree.repo5, flatpak-remote5,
