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.

OPTIONS

The following options are understood:

-h, --help

Show help options and exit.

-v, --verbose

Print debug information during command processing.

--version

Print version information and exit.

-r, --runtime

Use the non-devel runtime that is specified in the application metadata instead of the devel runtime.

--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, pulseaudio, system-bus, session-bus. 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, pulseaudio, system-bus, session-bus. 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. This option can be used multiple times.

The devel feature allows the application to access certain syscalls such as ptrace(), and perf_event_open().

The multiarch feature allows the application to execute programs compiled for an ABI other than the one supported natively by the system. For example, for the x86_64 architecture, 32-bit x86 binaries will be allowed as well.

--disallow=FEATURE

Disallow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch. 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.

--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.

--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.
