Setting up host_vars for each IPFS Cluster node

Add one file for each ipfs-cluster host. The filename should match a domain name from your inventory, i.e. example.org.

Each file should contain the following variables, updated for your cluster:

ipfs_peer_id: "<ipfs_daemon_peer_id>"
ipfs_private_key: "<ipfs_daemon_private_key>"

ipfs_cluster_id: "<cluster_peer_id>"
ipfs_cluster_private_key: "<cluster_peer_private_key>"

ipfs_cluster_peer_addr: "/dns4/<hostname>/tcp/9096/ipfs/<ipfs_cluster_peer_id>"

To generate the ipfs_peer_id/ipfs_private_key and ipfs_cluster_id/ipfs_cluster_private_key key-pairs, use ipfs-key. They must be all different (no ID or Key can be shared between daemons).

To install ipfs-key, with Go installed, run:

$ go get github.com/whyrusleeping/ipfs-key

then generate a key-pair:

$ ipfs-key | base64 -w 0

# or on macos
$ ipfs-key | base64

Generating a 2048 bit RSA key...
Success!
ID for generated key: Qmat3Bk4SixhZdU5j5pf2uXcpUuTSxKHQu7whbWrdFwn5g
CAASqAkwggSkAgEAAoIBAQCUzxjdml2fORveg9PN98qqiENexLzoaSeNc6N7K8iVzneCU1aDZpM...

Where:

  • the value of ID for generated key: <PeerId> is your ipfs_peer_id or ipfs_cluster_id
  • the subsequent line is your ipfs_private_key or ipfs_cluster_private_key, encoded as base64

Copy those values into your host config file.

For ipfs_cluster_peer_addr you need to specify a valid multiaddr by taking the example below

"/dns4/<hostname>/tcp/9096/ipfs/<ipfs_cluster_peer_id>"

and replacing:

hostname: with the host from your invetory that this file is for, e.g example.org ipfs_cluster_peer_id: with the peer id for this cluster node, that you just created.

You can also define ipfs_cluster_peername to name your cluster peer for conviniency. Otherwise, the hostname will be used.
