NAME

       ostree.repo-config - OSTree repository configuration

DESCRIPTION

       The config file in an OSTree repository is a "keyfile" in the XDG Desktop Entry
       Specification[1] format. It has several global flags, as well as zero or more remote
       entries which describe how to access remote repositories.

       See ostree.repo(5) for more information about OSTree repositories.

[CORE] SECTION OPTIONS

       Repository-global options. The following entries are defined:

       mode
           One of bare, bare-user or archive-z2 (note that archive is used everywhere else.)

       repo_version
           Currently, this must be set to 1.

       auto-update-summary
           Boolean value controlling whether or not to automatically update the summary file
           after any ref is added, removed, or updated. Other modifications which may render a
           summary file stale (like static deltas, or collection IDs) do not currently trigger an
           auto-update.

       commit-update-summary
           This option is deprecated. Use auto-update-summary instead, for which this option is
           now an alias.

       fsync
           Boolean value controlling whether or not to ensure files are on stable storage when
           performing operations such as commits, pulls, and checkouts. Defaults to true.

           If you disable fsync, OSTree will no longer be robust against kernel crashes or power
           loss.

           You might choose to disable this for local development repositories, under the
           assumption they can be recreated from source. Similarly, you could disable for a
           mirror where you could re-pull.

           For the system repository, you might choose to disable fsync if you have
           uninterruptable power supplies and a well tested kernel.

       min-free-space-percent
           Integer percentage value (0-99) that specifies a minimum percentage of total space (in
           blocks) in the underlying filesystem to keep free. The default value is 3, which is
           enforced when neither this option nor min-free-space-size are set.

           If min-free-space-size is set to a non-zero value, min-free-space-percent is ignored.

       min-free-space-size
           Value (in power-of-2 MB, GB or TB) that specifies a minimum space in the underlying
           filesystem to keep free. Examples of acceptable values: 500MB (524 288 000 bytes), 1GB
           (1 073 741 824 bytes), 1TB (1 099 511 627 776 bytes).

           If this option is set to a non-zero value, and min-free-space-percent is also set,
           this option takes priority.

       add-remotes-config-dir
           Boolean value controlling whether new remotes will be added in the remotes
           configuration directory. Defaults to true for system ostree repositories. When this is
           false, remotes will be added in the repository's config file.

           This only applies to repositories that use a remotes configuration directory such as
           system ostree repositories, which use /etc/ostree/remotes.d. Non-system repositories
           do not use a remotes configuration directory unless one is specified when the
           repository is opened.

       payload-link-threshold
           An integer value that specifies a minimum file size for creating a payload link. By
           default it is disabled.

       collection-id
           A reverse DNS domain name under your control, which enables peer to peer distribution
           of refs in this repository. See the --collection-id section in ostree-init(1)

[REMOTE NAME"] SECTION OPTIONS"

       Describes a remote repository location.

       url
           Must be present; declares URL for accessing metadata and content for remote. See also
           contenturl. The supported schemes are documented below.

       contenturl
           Declares URL for accessing content (filez, static delta parts). When specified, url is
           used just for metadata: summary, static delta "superblocks".

       branches
           A list of strings. Represents the default configured branches to fetch from the remote
           when no specific branches are requested during a pull operation.

       proxy
           A string value, if given should be a URL for a HTTP proxy to use for access to this
           repository.

       gpg-verify
           A boolean value, defaults to true. Controls whether or not OSTree will require commits
           to be signed by a known GPG key. For more information, see the ostree(1) manual under
           GPG.

       gpg-verify-summary
           A boolean value, defaults to false. Controls whether or not OSTree will check if the
           summary is signed by a known GPG key. For more information, see the ostree(1) manual
           under GPG.

       tls-permissive
           A boolean value, defaults to false. By default, server TLS certificates will be
           checked against the system certificate store. If this variable is set, any certificate
           will be accepted.

       tls-client-cert-path
           Path to file for client-side certificate, to present when making requests to this
           repository.

       tls-client-key-path
           Path to file containing client-side certificate key, to present when making requests
           to this repository.

       tls-ca-path
           Path to file containing trusted anchors instead of the system CA database.

       http2
           A boolean value, defaults to true. By default, libostree will use HTTP2; setting this
           to false will disable it. May be useful to work around broken servers.

       unconfigured-state
           If set, pulls from this remote will fail with the configured text. This is intended
           for OS vendors which have a subscription process to access content.

/ETC/OSTREE/REMOTES.D

       In addition to the /ostree/repo/config file, remotes may also be specified in
       /etc/ostree/remotes.d. The remote configuration file must end in .conf; files whose name
       does not end in .conf will be ignored.

REPOSITORY URL/CONTENTURL

       Originally, OSTree had just a url option for remotes. Since then, the contenturl option
       was introduced. Both of these support file, http, and https schemes.

       Additionally, both of these can be prefixed with the string mirrorlist=, which instructs
       the client that the target url is a "mirrorlist" format, which is a plain text file of
       newline-separated URLs. Earlier URLs will be given precedence.

       Note that currently, the tls-ca-path and tls-client-cert-path options apply to every HTTP
       request, even when contenturl and/or mirrorlist are in use. This may change in the future
       to only apply to metadata (i.e.  url, not contenturl) fetches.

PER-REMOTE GPG KEYRINGS AND VERIFICATION

       OSTree supports a per-remote GPG keyring, as well as a gpgkeypath option. For more
       information see ostree(1). in the section GPG verification.

PER-REMOTE HTTP COOKIES

       Some content providers may want to control access to remote repositories via HTTP cookies.
       The ostree remote add-cookie and ostree remote delete-cookie commands will update a
       per-remote lookaside cookie jar, named $remotename.cookies.txt.
