IPFS Cluster CTL

IPFS Cluster Dec 15, 2019

The ipfs-cluster-ctl command line application is a  user-friendly REST API client for IPFS Cluster. It allows to perform all  the operations supported by a Cluster peer:

Usage

Usage information can be obtained by running:

$ ipfs-cluster-ctl --help

You can also obtain command-specific help with ipfs-cluster-ctl help [cmd]. The (--host) can be used to talk to any remote cluster peer (localhost is used by default). In summary, it works as follows:

$ ipfs-cluster-ctl id                                                       # show cluster peer and ipfs daemon information
$ ipfs-cluster-ctl peers ls                                                 # list cluster peers
$ ipfs-cluster-ctl peers rm <peerid>                                        # remove a cluster peer
$ ipfs-cluster-ctl add myfile.txt http://domain.com/file.txt                # adds content to the cluster
$ ipfs-cluster-ctl pin add Qma4Lid2T1F68E3Xa3CpE6vVJDLwxXLD8RfiB9g1Tmqp58   # pins a CID in the cluster
$ ipfs-cluster-ctl pin rm Qma4Lid2T1F68E3Xa3CpE6vVJDLwxXLD8RfiB9g1Tmqp58    # unpins a CID from the clustre
$ ipfs-cluster-ctl pin ls [CID]                                             # list tracked CIDs (shared state)
$ ipfs-cluster-ctl status [CID]                                             # list current status of tracked CIDs (local state)
$ ipfs-cluster-ctl sync Qma4Lid2T1F68E3Xa3CpE6vVJDLwxXLD8RfiB9g1Tmqp58      # re-sync seen status against status reported by the IPFS daemon
$ ipfs-cluster-ctl recover Qma4Lid2T1F68E3Xa3CpE6vVJDLwxXLD8RfiB9g1Tmqp58   # attempt to re-pin/unpin CIDs in error state

Authentication

The IPFS Cluster API can be configured with Basic Authentication support.

ipfs-cluster-ctl --basic-auth <username:password> will use the given credentials to perform the request.

Note that unless --force-http is passed, using basic-auth is only supported on HTTPS requests or using the libp2p API endpoint (which uses an encrypted channel).

Using the libp2p API endpoint

Since 0.3.5, IPFS Cluster provides a libp2p endpoint for  the HTTP API which provides channel security without the need to  configure SSL certificates, by either re-using the peer’s libp2p host or  by setting up a new one with the given parameters in the API  configuration.

In order to have ipfs-cluster-ctl use a libp2p endpoint, provide the --host flag as follows:

ipfs-cluster-ctl --host /ip4/<ip>/ipfs/<peerID> ...

or

ipfs-cluster-ctl --host /dnsaddr/mydomain.com ... (setting a _dnsaddr TXT dnsaddr=peer_multiaddress field in your dns).

If the libp2p peer you’re contacting is using a cluster secret (a private networks key), you will also need to provide --secret <32 byte-hex-encoded key> to the command.

We recommend that you alias the ipfs-cluster-ctl command in your shell to something shorter and with the right global options.

Exit codes

ipfs-cluster-ctl will exit with:

  • 0: the request/operation succeeded. The output contains the response data.
  • 1: argument error, network error or any other error  which prevented the application to perform a request and obtain a  response from the IPFS Cluster API. In such case, the output contains  the contents of the error and the HTTP code 0.
  • 2: IPFS Cluster peer error. The request was performed  correctly but the response is an error (HTTP status 4xx or 5xx). In such  case, the output contains the contents of the error and the HTTP code  associated to it.

Debugging

ipfs-cluster-ctl takes a --debug flag which allows to inspect request paths and raw response bodies.
