NAME

git-annex-p2phttp - HTTP server for the git-annex API

SYNOPSIS

git-annex p2phttp

DESCRIPTION

This is a HTTP server for the git-annex API. It is the git-annex equivilant of git-http-backend(1), for serving a repository over HTTP with write access for authenticated users.

This does not serve the git repository over HTTP, only the git-annex API.

Typically a remote will have remote.name.url set to a http url as usual, and remote.name.annexUrl set to an annex+http url such as "annex+http://example.com/git-annex/". The annex+http url is served by this server, and uses port 9417 by default.

Note that, when remote.name.url and remote.name.annexUrl contain the same hostname, they are assumed by git-annex to support the same users and passwords. So, git-annex will use the password for the remote.name.url to log into the remote.name.annexUrl.

As well as serving the git-annex HTTP API, this server provides a convenient way to download the content of any key, by using the path "/git-annex/$uuid/$key". For example:

$ curl http://example.com:9417/git-annex/f11773f0-11e1-45b2-9805-06db16768efe/key/SHA256E-s6--5891b5b522d5df086d0ff0b110fbd9d21bb4fc7163af34d08286a2e846f6be03

OPTIONS

  • --jobs=N -JN

    This or annex.jobs must be set to configure the number of worker threads that serve connections to the webserver.

    Since the webserver itself also uses one of these threads, this needs to be set to 2 or more.

    A good choice is often one worker per CPU core: --jobs=cpus

  • --proxyconnections=N

    When this command is run in a repository that is configured to act as a proxy for some of its remotes, this is the maximum number of idle connections to keep open to proxied remotes.

    The default is 1.

  • --clusterjobs=N

    When this command is run in a repository that is a gateway for a cluster, this is the number of concurrent jobs to use to access nodes of the cluster, per connection to the webserver.

    The default is 1.

    A good choice for this will be a balance between the number of nodes in the cluster and the value of --jobs.

    For example, if the cluster has 4 nodes, and --jobs=4, using --clusterjobs=4 will make all nodes in the cluster be accessed concurrently, which is often optimal. But around 20 cores can be needed when the webserver is busy.

  • --port=N

    Port to listen on. The default is port 9417, which is the default port used for an annex+http or annex+https url.

    It is not recommended to run this command as root in order to use a low port like port 80. It will not drop permissions when run as root.

  • --bind=address

    What address to bind to. The default is to bind to all addresses.

  • --certfile=filename

    TLS certificate file to use. Combining this with --privatekeyfile makes the server use HTTPS.

  • --privatekeyfile=filename

    TLS private key file to use. Combining this with --certfile makes the server use HTTPS.

  • --chainfile=filename

    TLS chain file to use. This option can be repeated any number of times.

  • --authenv

    Allows users to be authenticated with a username and password. For security, this only allows authentication when the user connects over HTTPS.

    To configure the passwords, set environment variables like GIT_ANNEX_P2PHTTP_PASSWORD_alice=foo123

    The permissions of users can also be configured by setting environment variables like GIT_ANNEX_P2PHTTP_PERMISSIONS_alice=readonly. The value can be either "readonly" or "appendonly". When this is not set, the default is to give the user full read+write+remove access.

  • --authenv-http

    Like --authenv, but allows authentication when the user connects over HTTP. This is not secure, since HTTP basic authentication is not encrypted.

  • --unauth-readonly

    Allows unauthenticated users to read the repository, but not make modifications to it.

    This can be combined with --authenv or --authenv-http to allow anonymous readonly access, and authenticated write access.

  • --unauth-appendonly

    Allows unauthenticated users to read the repository, and store data in it, but not remove data from it.

    This can be combined with --authenv or --authenv-http to allow anonymous appendonly access, and authenticated remove access.

  • --unauth-nolocking

    By default, when --unauth-readonly or --unauth-appendonly is used, unauthenticated users are allowed to lock content in the repository. This option prevents that.

    Locking content prevents it from being dropped from the repository so it may be that an unauthenticated user abuses that, and this option can be used in such a situation.

    Note that enabling this option will prevent unauthenticated users from dropping content from their other remotes in some cases.

  • --wideopen

    Gives unauthenticated users full read+write+remove access to the repository.

    Please think carefully before enabling this option.
