flatpak Developer Alexander Larsson alexl@redhat.com flatpak build 1 flatpak-build Build in a directory flatpak build OPTION DIRECTORY COMMAND ARG Runs a build command in a directory. DIRECTORY must have been initialized with flatpak build-init. The sdk that is specified in the metadata file in the directory is mounted at /usr and the files and var subdirectories are mounted at /app and /var, respectively. They are writable, and their contents are preserved between build commands, to allow accumulating build artifacts there. 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. -r --runtime Use the non-devel runtime that is specified in the application metadata instead of the devel runtime. -p --die-with-parent Kill the build process and all children when the launching process dies. --bind-mount=DEST=SOURCE Add a custom bind mount in the build namespace. Can be specified multiple times. --build-dir=PATH Start the build in this directory (default is in the current directory). --share=SUBSYSTEM Share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times. --unshare=SUBSYSTEM Don't share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times. --socket=SOCKET Expose a well-known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be used multiple times. --nosocket=SOCKET Don't expose a well-known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be used multiple times. --device=DEVICE Expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, input, usb, kvm, shm, all. This option can be used multiple times. --nodevice=DEVICE Don't expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, input, usb, kvm, shm, all. This option can be used multiple times. --allow=FEATURE Allow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times. See flatpak-build-finish1 for the meaning of the various features. --disallow=FEATURE Disallow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times. --filesystem=FILESYSTEM[:ro|:create] Allow the application access to a subset of the filesystem. This overrides to the Context section from the application metadata. FILESYSTEM can be one of: home, host, host-os, host-etc, host-root, xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, xdg-run, xdg-config, xdg-cache, xdg-data, an absolute path, or a homedir-relative path like ~/dir or paths relative to the xdg dirs, like xdg-download/subdir. The optional :ro suffix indicates that the location will be read-only. The optional :create suffix indicates that the location will be read-write and created if it doesn't exist. This option can be used multiple times. See the "[Context] filesystems" list in flatpak-metadata5 for details of the meanings of these filesystems. Before flatpak 1.17.0, access to host was granted by default. --nofilesystem=FILESYSTEM Remove access to the specified subset of the filesystem from the application. This overrides to the Context section from the application metadata. FILESYSTEM can be one of: home, host, host-os, host-etc, host-root xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, an absolute path, or a homedir-relative path like ~/dir. This option can be used multiple times. --with-appdir Expose and configure access to the per-app storage directory in $HOME/.var/app. This is not normally useful when building, but helps when testing built apps. --add-policy=SUBSYSTEM.KEY=VALUE Add generic policy option. For example, "--add-policy=subsystem.key=v1 --add-policy=subsystem.key=v2" would map to this metadata: [Policy subsystem] key=v1;v2; This option can be used multiple times. --remove-policy=SUBSYSTEM.KEY=VALUE Remove generic policy option. This option can be used multiple times. --env=VAR=VALUE Set an environment variable in the application. This overrides to the Context section from the application metadata. This option can be used multiple times. --unset-env=VAR Unset an environment variable in the application. This overrides the unset-environment entry in the [Context] group of the metadata, and the [Environment] group. This option can be used multiple times. --env-fd=FD Read environment variables from the file descriptor FD, and set them as if via --env. This can be used to avoid environment variables and their values becoming visible to other users. Each environment variable is in the form VAR=VALUE followed by a zero byte. This is the same format used by env -0 and /proc/*/environ. --own-name=NAME Allow the application to own the well-known name NAME on the session bus. This overrides to the Context section from the application metadata. This option can be used multiple times. --talk-name=NAME Allow the application to talk to the well-known name NAME on the session bus. This overrides to the Context section from the application metadata. This option can be used multiple times. --system-own-name=NAME Allow the application to own the well-known name NAME on the system bus. This overrides to the Context section from the application metadata. This option can be used multiple times. --system-talk-name=NAME Allow the application to talk to the well-known name NAME on the system bus. This overrides to the Context section from the application metadata. This option can be used multiple times. --persist=FILENAME If the application doesn't have access to the real homedir, make the (homedir-relative) path FILENAME a bind mount to the corresponding path in the per-application directory, allowing that location to be used for persistent data. This overrides to the Context section from the application metadata. This option can be used multiple times. --sdk-dir=DIR Normally if there is a usr directory in the build dir, this is used for the runtime files (this can be created by --writable-sdk or --type=runtime arguments to build-init). If you specify --sdk-dir, this directory will be used instead. Use this if you passed --sdk-dir to build-init. --readonly Mount the normally writable destination directories read-only. This can be useful if you want to run something in the sandbox but guarantee that it doesn't affect the build results. For example tests. --metadata=FILE Use the specified filename as metadata in the exported app instead of the default file (called metadata). This is useful if you build multiple things from a single build tree (such as both a platform and a sdk). --log-session-bus Log session bus traffic. This can be useful to see what access you need to allow in your D-Bus policy. --log-system-bus Log system bus traffic. This can be useful to see what access you need to allow in your D-Bus policy. $ flatpak build /build/my-app rpmbuild my-app.src.rpm flatpak1, flatpak-build-init1, flatpak-build-finish1, flatpak-build-export1
