Clusters

The clusters endpoint allows you to retrieve information about clusters as well as provision new ones and delete existing clusters.

Prior to using any of these endpoints, take a look at the Getting Started section within the API reference to understand how to create your long lived API key and retrieve a short lived key to be able to execute operations against the API.

Listing clusters

Generic listing

The /clusters endpoint itself will list from the Personal team.

Status code: 200 OK

Team-specific listing

To retrieve the list of clusters that exist for a specific team, you should hit the standard clusters endpoint followed by the team ID as a query parameter:

GET /clusters?team_id={team_id}

This will provide all clusters that exist within that team.

Status code: 200 OK

Retrieving cluster details

Details about a specific cluster can be retrieved using the GET /clusters/{cluster_id} endpoint.

The resulting response will be the details as defined in the Cluster Object, with the following additional fields:

  • state - the current state of the cluster, eg. ‘creating’, ‘ready’
  • oldest_backup - the time of oldest backup available

Also included is the instance details about the cluster. This field is an array of all details for the primary and related read replica instances.

Cluster Instance object

Attribute Type Description
id string Unique identifier for the cluster
name string the name of the cluster
type string the type of the instance (‘primary’ or ‘read_replica’)
url string the connection url for the instance
provider_id string the provider hosting the instance
region_id string the region the provider is hosting the instance

Provisioning a cluster

Clusters can be provisioned against the API:

POST /clusters

There are a number of required and a few optional fields when creating your cluster:

  • Name - text [required]
  • Team - Unique team identifier [required]
  • Plan - Unique plan identifier [required]
  • Storage - Integer in MB [required]
  • Provider - Unique provider identifier [required]
  • Region - Unique region identifier [required]
  • Version - Integer Postgres major version [required]
  • HA - Boolean to specify HA on or off (optional, default: false)

Refer to the Providers section for details on retrieving the unique identifiers for plans, providers, and regions.

An example request to create a cluster:

$ curl -X POST https://api.crunchybridge.com/clusters \
  -d '{
    "name": "staging",
    "team_id": "eaevtjiudzeq7bsqbbpiscund4",
    "plan_id": "hobby-2",
    "storage": 100,
    "provider_id": "aws",
    "region_id": "us-east-1",
    "major_version": 13
  }' -H "Authorization: Bearer lf6b76vzhzc2hhudyacj4aqlgy"

Status codes:

  • 201 Created. A new cluster is provisioned.
  • 400 Bad Request. The request contains an invalid value, for example a decimal value for major_version.
  • 409 Conflict. The request specifies a non-unique name (i.e. a cluster that already exists).

Forking a cluster

Clusters can be forked at point in time against the API. Required fields are the same for provisioning a new cluster with the addition of one optional field:

  • Target Time - the target point in time, in RFC3339 format [optional, default: now()]

The target time should be a time between the oldest_backup and now(). The oldest backup time can be obtained from the cluster details listing API endpoint. Note: If not oldest backup is listed, then a backup currently doesn’t not exist for the cluster. This is common shortly after a cluster is first created.

POST /clusters/{cluster_id}/forks

An example POST to fork a cluster:

$ curl -X POST https://api.crunchybridge.com/clusters \
  -d '{
    "name": "staging-fork",
    "team_id": "eaevtjiudzeq7bsqbbpiscund4",
    "plan_id": "hobby-2",
    "storage": 100,
    "provider_id": "aws",
    "region_id": "us-east-1",
    "major_version": 13,
    "target_time": "2009-11-10T23:00:00Z"
  }' -H "Authorization: Bearer lf6b76vzhzc2hhudyacj4aqlgy"

Status codes:

  • 201 Created. A new fork is provisioned.
  • 400 Bad Request. The request contains an invalid value, or a backup currently does not exist.

Deleting a cluster

DELETE /clusters/{cluster_id}

curl -X DELETE https://api.crunchybridge.com/clusters/rvf73a77ozfsvcttryebfrnlem -H "Authorization: Bearer lf6b76vzhzc2hhudyacj4aqlgy"

Status codes:

Managing cluster firewall rules

The API allows you to create, update, delete, and retrieve a list of firewall rules.

Currently, you can create, update, or delete one firewall rule per call.

Retrieving firewall rules

Pass in the cluster ID as a path parameter to the following endpoint:

GET /clusters/{cluster_id}/firewall

Status code: 200 OK

{
  "firewall_rules": [
    {
      "id": "rwhpndhwrfdetco3wypdyuw4vm",
      "rule": "0.0.0.0/0"
    }
  ]
}

curl -X PUT https://api.crunchybridge.com/clusters/rvf73a77ozfsvcttryebfrnlem/firewall/6ulthse7k5gm7kxz4cqwojagki \
  -d '{"rule":"172.27.153.74/24"}' -H "Authorization: Bearer lf6b76vzhzc2hhudyacj4aqlgy"

Status codes:

  • 204 No Content. The specified firewall rule is updated.
  • 400 Bad Request. The request body contains invalid values (e.g. invalid IP address).
