package ipfscluster

import "github.com/ipfs/ipfs-cluster"

Package ipfscluster implements a wrapper for the IPFS deamon which allows to orchestrate pinning operations among several IPFS nodes.

IPFS Cluster uses a go-libp2p-raft to keep a shared state between the different cluster peers. It also uses LibP2P to enable communication between its different components, which perform different tasks like managing the underlying IPFS daemons, or providing APIs for external control.

}

API is a component which offers an API for Cluster. This is a base component.

type Cluster Uses

type Cluster struct {
    // contains filtered or unexported fields
}

Cluster is the main IPFS cluster component. It provides the go-API for it and orchestrates the components that make up the system.

func NewCluster Uses

func NewCluster(
    host host.Host,
    cfg *Config,
    consensus Consensus,
    api API,
    ipfs IPFSConnector,
    st state.State,
    tracker PinTracker,
    monitor PeerMonitor,
    allocator PinAllocator,
    informer Informer,
) (*Cluster, error)

NewCluster builds a new IPFS Cluster peer. It initializes a LibP2P host, creates and RPC Server and client and sets up all components.

The new cluster peer may still be performing initialization tasks when this call returns (consensus may still be bootstrapping). Use Cluster.Ready() if you need to wait until the peer is fully up.

func (*Cluster) AddFile Uses

func (c *Cluster) AddFile(reader *multipart.Reader, params *api.AddParams) (cid.Cid, error)

AddFile adds a file to the ipfs daemons of the cluster. The ipfs importer pipeline is used to DAGify the file. Depending on input parameters this DAG can be added locally to the calling cluster peer's ipfs repo, or sharded across the entire cluster.

func (*Cluster) ConnectGraph Uses

func (*Cluster) ID Uses

func (c *Cluster) ID() api.ID

ID returns information about the Cluster peer

func (*Cluster) Join Uses

func (c *Cluster) Join(addr ma.Multiaddr) error

Join adds this peer to an existing cluster by bootstrapping to a given multiaddress. It works by calling PeerAdd on the destination cluster and making sure that the new peer is ready to discover and contact the rest.

func (*Cluster) PeerAdd Uses

func (c *Cluster) PeerAdd(pid peer.ID) (api.ID, error)

PeerAdd adds a new peer to this Cluster.

For it to work well, the new peer should be discoverable (part of our peerstore or connected to one of the existing peers) and reachable. Since PeerAdd allows to add peers which are not running, or reachable, it is recommended to call Join() from the new peer instead.

The new peer ID will be passed to the consensus component to be added to the peerset.

func (*Cluster) PeerRemove Uses

func (c *Cluster) PeerRemove(pid peer.ID) error

PeerRemove removes a peer from this Cluster.

The peer will be removed from the consensus peerset. This may first trigger repinnings for all content if not disabled.

func (*Cluster) Peers Uses

func (c *Cluster) Peers() []api.ID

Peers returns the IDs of the members of this Cluster.

func (*Cluster) Pin Uses

func (c *Cluster) Pin(pin api.Pin) error

Pin makes the cluster Pin a Cid. This implies adding the Cid to the IPFS Cluster peers shared-state. Depending on the cluster pinning strategy, the PinTracker may then request the IPFS daemon to pin the Cid.

Pin returns an error if the operation could not be persisted to the global state. Pin does not reflect the success or failure of underlying IPFS daemon pinning operations.

If the argument's allocations are non-empty then these peers are pinned with priority over other peers in the cluster. If the max repl factor is less than the size of the specified peerset then peers are chosen from this set in allocation order. If the min repl factor is greater than the size of this set then the remaining peers are allocated in order from the rest of the cluster. Priority allocations are best effort. If any priority peers are unavailable then Pin will simply allocate from the rest of the cluster.

func (*Cluster) PinGet Uses

func (c *Cluster) PinGet(h cid.Cid) (api.Pin, error)

PinGet returns information for a single Cid managed by Cluster. The information is obtained from the current global state. The returned api.Pin provides information about the allocations assigned for the requested Cid, but does not indicate if the item is successfully pinned. For that, use Status(). PinGet returns an error if the given Cid is not part of the global state.

func (*Cluster) Pins Uses

func (c *Cluster) Pins() []api.Pin

Pins returns the list of Cids managed by Cluster and which are part of the current global state. This is the source of truth as to which pins are managed and their allocation, but does not indicate if the item is successfully pinned. For that, use StatusAll().

    Secret []byte

    // Leave Cluster on shutdown. Politely informs other peers
    // of the departure and removes itself from the consensus
    // peer set. The Cluster size will be reduced by one.
    LeaveOnShutdown bool

    // Listen parameters for the Cluster libp2p Host. Used by
    // the RPC and Consensus components.
    ListenAddr ma.Multiaddr

    // Time between syncs of the consensus state to the
    // tracker state. Normally states are synced anyway, but this helps
    // when new nodes are joining the cluster. Reduce for faster
    // consistency, increase with larger states.
    StateSyncInterval time.Duration

    // Number of seconds between syncs of the local state and
    // the state of the ipfs daemon. This ensures that cluster
    // provides the right status for tracked items (for example
    // to detect that a pin has been removed. Reduce for faster
    // consistency, increase when the number of pinned items is very
    // large.
    IPFSSyncInterval time.Duration

    // ReplicationFactorMax indicates the target number of nodes
    // that should pin content. For exampe, a replication_factor of
    // 3 will have cluster allocate each pinned hash to 3 peers if
    // possible.
    // See also ReplicationFactorMin. A ReplicationFactorMax of -1
    // will allocate to every available node.
    ReplicationFactorMax int

    // ReplicationFactorMin indicates the minimum number of healthy
    // nodes pinning content. If the number of nodes available to pin
    // is less than this threshold, an error will be returned.
    // In the case of peer health issues, content pinned will be
    // re-allocated if the threshold is crossed.
    // For exampe, a ReplicationFactorMin of 2 will allocate at least
    // two peer to hold content, and return an error if this is not
    // possible.
    ReplicationFactorMin int

    // MonitorPingInterval is the frequency with which a cluster peer pings
    // the monitoring component. The ping metric has a TTL set to the double
    // of this value.
    MonitorPingInterval time.Duration

    // PeerWatchInterval is the frequency that we use to watch for changes
    // in the consensus peerset and save new peers to the configuration
    // file. This also affects how soon we realize that we have
    // been removed from a cluster.
    PeerWatchInterval time.Duration

    // If true, DisableRepinning, ensures that no repinning happens
    // when a node goes down.
    // This is useful when doing certain types of maintainance, or simply
    // when not wanting to rely on the monitoring system which needs a revamp.
    DisableRepinning bool

    // Peerstore file specifies the file on which we persist the
    // libp2p host peerstore addresses. This file is regularly saved.
    PeerstoreFile string

    WaitForSync() error
    // Clean removes all consensus data
    Clean() error
    // Peers returns the peerset participating in the Consensus
    Peers() ([]peer.ID, error)

type PeerMonitor Uses

type PeerMonitor interface {
    Component
    // LogMetric stores a metric. It can be used to manually inject
    // a metric to a monitor.

    // a problem (i.e. metrics not arriving as expected). Alerts can be used
    // to trigger self-healing measures or re-pinnings of content.
    Alerts() <-chan api.Alert
}

PeerMonitor is a component in charge of publishing a peer's metrics and reading metrics from other peers in the cluster. The PinAllocator will use the metrics provided by the monitor as candidates for Pin allocations.

The PeerMonitor component also provides an Alert channel which is signaled when a metric is no longer received and the monitor identifies it as a problem.

    AddPeer(p peer.ID)
    RmPeer(p peer.ID)
}

Peered represents a component which needs to be aware of the peers in the Cluster and of any changes to the peer set.

type PinAllocator Uses

type PinAllocator interface {
    Component

    // least). The "current" map contains valid metrics for peers
    // which are currently pinning the content. The candidates map
    // contains the metrics for all peers which are eligible for pinning
    // the content.
    Allocate(c cid.Cid, current, candidates, priority map[peer.ID]api.Metric) ([]peer.ID, error)
}

PinAllocator decides where to pin certain content. In order to make such decision, it receives the pin arguments, the peers which are currently allocated to the content and metrics available for all peers which could allocate the content.

type PinTracker interface {
    Component
    // Track tells the tracker that a Cid is now under its supervision
    // The tracker may decide to perform an IPFS pin.

    // may perform an IPFS unpin operation.
    Untrack(cid.Cid) error
    // StatusAll returns the list of pins with their local status.
    StatusAll() []api.PinInfo
    // Status returns the local status of a given Cid.
    Status(cid.Cid) api.PinInfo
    // SyncAll makes sure that all tracked Cids reflect the real IPFS status.
    // It returns the list of pins which were updated by the call.
    SyncAll() ([]api.PinInfo, error)
    // Sync makes sure that the Cid status reflect the real IPFS status.
    // It returns the local status of the Cid.
    Sync(cid.Cid) (api.PinInfo, error)
    // RecoverAll calls Recover() for all pins tracked.
    RecoverAll() ([]api.PinInfo, error)
    // Recover retriggers a Pin/Unpin operation in a Cids with error status.
    Recover(cid.Cid) (api.PinInfo, error)
}

PinTracker represents a component which tracks the status of the pins in this cluster and ensures they are in sync with the IPFS daemon. This component should be thread safe.

type RPCAPI Uses
