flatpak-build-export - Create a repository from a build
flatpak build-export [OPTION...] LOCATION DIRECTORY
Creates or updates a repository with an application build.
LOCATION is the location of the repository. DIRECTORY must be a finalized
build directory. If BRANCH is not specified, it is assumed to be
If LOCATION exists, it is assumed to be an OSTree repository,
otherwise a new OSTree repository is created at this location. The
repository can be inspected with the ostree tool.
The contents of DIRECTORY are committed on the branch with name
app/APPNAME/ARCH/BRANCH, where ARCH is the architecture of the runtime that
the application is using. A commit filter is used to enforce that only the
contents of the files/ and export/ subdirectories and the metadata file are
included in the commit, anything else is ignored.
When exporting a flatpak to be published to the internet,
--collection-id=COLLECTION-ID should be specified as a globally
unique reverse DNS value to identify the collection of flatpaks this will be
added to. Setting a globally unique collection ID allows the apps in the
repository to be shared over peer to peer systems without needing further
The build-update-repo command should be used to update repository
metadata whenever application builds are added to a repository.
The following options are understood:
Show help options and exit.
One line subject for the commit message.
Full description for the commit message.
Set as the collection ID of the repository. Setting a
globally unique collection ID allows the apps in the repository to be shared
over peer to peer systems without needing further configuration. If exporting
to an existing repository, the collection ID must match the existing
configured collection ID for that repository.
Mark the commit to be included in the named subset. This
will cause the commit to be put in the named subset summary (in addition to
the main one), allowing users to see only this subset instead of the whole
Specify the architecture component of the branch to
export. Only host compatible architectures can be specified; see flatpak
--supported-arches for valid values.
Exclude files matching PATTERN from the commit. This
option can be used multiple times.
Don't exclude files matching PATTERN from the commit,
even if they match the --exclude patterns. This option can be used
Use the specified filename as metadata in the exported
app instead of the default file (called metadata). This is useful if you want
to commit multiple things from a single build tree, typically used in
combination with --files and --exclude.
Use the files in the specified subdirectory as the file
contents, rather than the regular files directory.
Use the specified ISO 8601 formatted date or NOW, for the
current time, in the commit metadata and, if --update-appstream is
used, the appstream data.
Mark the build as end-of-life. REASON is a message that
may be shown to users installing this build.
Mark the build as end-of-life. Unlike
--end-of-life, this one takes an ID that supersedes the current one. By
the user's request, the application data may be preserved for the new
Don't fsync when writing to the repository. This can
result in data loss in exceptional situations, but can improve performance
when working with temporary or test repositories.
Update the appstream branch after the build.
Don't update the summary file after the new commit is
added. This means the repository will not be useful for serving over http
until build-update-repo has been run. This is useful is you want to do
multiple repo operations before finally updating the summary.
Sign the commit with this GPG key. This option can be
used multiple times.
GPG Homedir to use when looking for keyrings
Export a runtime instead of an app (this uses the usr
subdir as files).
Print debug information during command processing.
Print OSTree debug information during command
