ipfs-cluster-ctl

ipfs-cluster-ctl is the client application to manage the cluster nodes and perform actions. ipfs-cluster-ctl uses the HTTP API provided by the nodes and it is completely separate from the cluster service.

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 requests with --https or using the libp2p API endpoint.

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.

Exit codes

ipfs-cluster-ctl will exit with:

Debugging

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