Provision cluster​

You can provision new clusters using the admin interface.

note

  • This operation requires superuser privileges.

  • When provisioning a new cluster, you need to initialize cluster metadata. Cluster metadata can be initialized through the pulsar-admin CLI only. It cannot be performed via Pulsar admin APIs (REST API and Java admin API).

You can provision a new cluster using the create subcommand. Here's an example:

pulsar-admin clusters create cluster-1 \
    --url http://my-cluster.org.com:8080 \
    --broker-url pulsar://my-cluster.org.com:6650

Get cluster configuration​

You can fetch the configuration for an existing cluster at any time.

Use the get subcommand and specify the name of the cluster. Here's an example:

pulsar-admin clusters get cluster-1

Output:

{
    "serviceUrl": "http://my-cluster.org.com:8080/",
    "serviceUrlTls": null,
    "brokerServiceUrl": "pulsar://my-cluster.org.com:6650/",
    "brokerServiceUrlTls": null
    "peerClusterNames": null
}

Update cluster​

Update cluster configuration​

You can update the configuration for an existing cluster at any time.

Use the update subcommand and specify new configuration values using flags.

pulsar-admin clusters update cluster-1 \
    --url http://my-cluster.org.com:4081 \
    --broker-url pulsar://my-cluster.org.com:3350

Update peer-cluster data​

Peer clusters can be configured for a given cluster in a Pulsar instance.

Use the update-peer-clusters subcommand and specify the list of peer-cluster names.

pulsar-admin update-peer-clusters cluster-1 --peer-clusters cluster-2

List cluster​

You can fetch a list of all clusters in a Pulsar instance.

Use the list subcommand.

pulsar-admin clusters list

Output:

cluster-1
cluster-2

Delete cluster​

Clusters can be deleted from a Pulsar instance.

Use the delete subcommand and specify the name of the cluster.

pulsar-admin clusters delete cluster-1
