OPTIONS¶
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. 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. 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,
  kvm, 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, kvm, 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. This option can be used multiple times.
See flatpak-build-finish(1) 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. 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, 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.
--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, 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.
--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
  directoryname 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.
