> Pinset orchestration for IPFS
<p align="center">
<img src="https://ipfscluster.io/cluster/png/IPFS_Cluster_color_no_text.png" alt="logo" width="300" height="300" />
</p>
[IPFS Cluster](https://ipfscluster.io) provides data orchestration across a swarm of IPFS daemons by allocating, replicating and tracking a global pinset distributed among multiple peers.
There are 3 different applications:
* A cluster peer application: `ipfs-cluster-service`, to be run along with `go-ipfs` as a sidecar.
* A client CLI application: `ipfs-cluster-ctl`, which allows easily interacting with the peer's HTTP API.
* An additional "follower" peer application: `ipfs-cluster-follow`, focused on simplifying the process of configuring and running follower peers.

// metadata for a single shard cannot fit within a single shard node. We
// make the following simplifying assumption: a single shard will not track
// more than 35,808,256 links (~2^25). This is the limit at which the current
// shard node format would need 2 levels of indirect nodes to reference
// all of the links. Note that this limit is only reached at shard sizes 7
// times the size of the current default and then only when files are all
// 1 byte in size. In the future we may generalize the shard dag to multiple
// indirect nodes to accommodate much bigger shard sizes. Also note that the
// move to using the identity hash function in cids of very small data
// will improve link density in shard nodes and further reduce the need for
// multiple levels of indirection.

# `ipfs-cluster-ctl`
> IPFS cluster management tool
`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).
For more information, please check the [Documentation](https://ipfscluster.io/documentation), in particular the [`ipfs-cluster-ctl` section](https://ipfscluster.io/documentation/ipfs-cluster-ctl).
