> 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.

package sharding
// dag.go defines functions for constructing and parsing ipld-cbor nodes
// of the clusterDAG used to track sharded DAGs in ipfs-cluster
// Most logic goes into handling the edge cases in which clusterDAG
// 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.

// The API exposes the routes in two ways: the first is through a regular

# `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).

/*
These functions are used to write an IPFS Cluster connectivity graph to a
graphviz-style dot file. Input an api.ConnectGraphSerial object, makeDot
does some preprocessing and then passes all 3 link maps to a
cluster-dotWriter which handles iterating over the link maps and writing
dot file node and edge statements to make a dot-file graph. Nodes are
labeled with the go-libp2p-peer shortened peer id. IPFS nodes are rendered
with turquoise boundaries, Cluster nodes with orange. Currently preprocessing
consists of moving IPFS swarm peers not connected to any cluster peer to
the IPFSLinks map in the event that the function was invoked with the
allIpfs flag. This allows all IPFS peers connected to the cluster to be
rendered as nodes in the final graph.

# `ipfs-cluster-follow`
> A tool to run IPFS Cluster follower peers
`ipfs-cluster-follow` allows to setup and run IPFS Cluster follower peers.
Follower peers can join collaborative clusters to track content in the
cluster. Follower peers do not have permissions to modify the cluster pinset
or access endpoints from other follower peers.
`ipfs-cluster-follow` allows to run several peers at the same time (each
joining a different cluster) and it is intended to be a very easy to use
application with a minimal feature set. In order to run a fully-featured peer
(follower or not), use `ipfs-cluster-service`.
### Usage
The `ipfs-cluster-follow` command is always followed by the cluster name
that we wish to work with. Full usage information can be obtained by running:
```
$ ipfs-cluster-follow --help
$ ipfs-cluster-follow --help
$ ipfs-cluster-follow <clusterName> --help
$ ipfs-cluster-follow <clusterName> info --help
$ ipfs-cluster-follow <clusterName> init --help
$ ipfs-cluster-follow <clusterName> run --help
$ ipfs-cluster-follow <clusterName> list --help
```
For more information, please check the [Documentation](https://ipfscluster.io/documentation), in particular the [`ipfs-cluster-follow` section](https://ipfscluster.io/documentation/ipfs-cluster-follow).

%s helps running IPFS Cluster follower peers.
Follower peers subscribe to a Cluster controlled by a set of "trusted
peers". They collaborate in pinning items as dictated by the trusted peers and
do not have the power to make Cluster-wide modifications to the pinset.
Follower peers cannot access information nor trigger actions in other peers.
%s can be used to follow different clusters by launching it
with different options. Each Cluster has an identity, a configuration
and a datastore associated to it, which are kept under
"~/%s/<cluster_name>".
For feedback, bug reports or any additional information, visit
https://github.com/ipfs-cluster/ipfs-cluster.
EXAMPLES:
List configured follower peers:
$ %s
Display information for a follower peer:
$ %s <clusterName> info
Initialize a follower peer:
$ %s <clusterName> init <example.url>
Launch a follower peer (will stay running):
$ %s <clusterName> run
List items in the pinset for a given cluster:
$ %s <clusterName> list
Getting help and usage info:
$ %s --help
$ %s <clusterName> --help
$ %s <clusterName> info --help
$ %s <clusterName> init --help
$ %s <clusterName> run --help
$ %s <clusterName> list --help

%s runs an IPFS Cluster peer.
A peer participates in the cluster consensus, follows a distributed log
of pinning and unpinning requests and manages pinning operations to a
configured IPFS daemon.
This peer also provides an API for cluster management, an IPFS Proxy API which
forwards requests to IPFS and a number of components for internal communication
using LibP2P. This is a simplified view of the components:
+------------------+
| ipfs-cluster-ctl |
+---------+--------+
|
| HTTP(s)
ipfs-cluster-service | HTTP
+----------+--------+--v--+----------------------+ +-------------+
| RPC | Peer 1 | API | IPFS Connector/Proxy +------> IPFS daemon |
+----^-----+--------+-----+----------------------+ +-------------+
| libp2p
|
+----v-----+--------+-----+----------------------+ +-------------+
| RPC | Peer 2 | API | IPFS Connector/Proxy +------> IPFS daemon |
+----^-----+--------+-----+----------------------+ +-------------+
|
|
+----v-----+--------+-----+----------------------+ +-------------+
| RPC | Peer 3 | API | IPFS Connector/Proxy +------> IPFS daemon |
+----------+--------+-----+----------------------+ +-------------+
%s needs valid configuration and identity files to run.
These are independent from IPFS. The identity includes its own
libp2p key-pair. They can be initialized with "init" and their
default locations are ~/%s/%s
and ~/%s/%s.
For feedback, bug reports or any additional information, visit
https://github.com/ipfs-cluster/ipfs-cluster.
EXAMPLES:
Initial configuration:
$ ipfs-cluster-service init
Launch a cluster:
$ ipfs-cluster-service daemon
Launch a peer and join existing cluster:
$ ipfs-cluster-service daemon --bootstrap /ip4/192.168.1.2/tcp/9096/p2p/QmPSoSaPXpyunaBwHs1rZBKYSqRV4bLRk32VGYLuvdrypL
Customize logs using --loglevel flag. To customize component-level
logging pass a comma-separated list of component-identifer:log-level
pair or without identifier for overall loglevel. Valid loglevels
are critical, error, warning, notice, info and debug.

URL during the launch of the daemon. If not, a default standard configuration
file will be created.
In the latter case, a cluster secret will be generated as required
by %s. Alternatively, this secret can be manually
provided with --custom-secret (in which case it will be prompted), or
by setting the CLUSTER_SECRET environment variable.
The --consensus flag allows to select an alternative consensus components for
in the newly-generated configuration.
Note that the --force flag allows to overwrite an existing
configuration with default values. To generate a new identity, please
remove the %s file first and clean any Raft state.
By default, an empty peerstore file will be created too. Initial contents can
be provided with the --peers flag. Depending on the chosen consensus, the
"trusted_peers" list in the "crdt" configuration section and the
"init_peerset" list in the "raft" configuration section will be prefilled to
the peer IDs in the given multiaddresses.
