Cluster

Clusters are a core primitive that represent a hosted Crunchy Bridge Postgres database along with all associated resources required to operate it, including the cloud server that it runs on.

Clusters are named such because the internal replica needed to maintain a cluster with high availability is considered to be part of same cluster as its primary, thereby making it a "cluster" of multiple servers. Public-facing replicas and forks on the other hand, are represented in the API as separate clusters with their own uniquely addressable IDs.

See also upgrading clusters to change a cluster's disk size, high availability configuration, or Postgres major version.

Part of the API reference collection

This page is part of the Crunchy Bridge API reference, and primarily meant to act as an exhaustive guide for technical integrations which are already in progress. To understand the basics of using the API, see API concepts and getting started.

The `Cluster` API resource

A database cluster.

Content type: application/json

Name	Nullable	Type	Description
`id`		`string` in EID format	The unique ID of the cluster.
`cluster_group`		`object` of type `ClusterGroupobject`	The cluster group that the cluster belongs to, if any.
`cpu`		`integer`	The number of CPU units on the cluster's instance.
`created_at`		`string` of date/time formatted as RFC 3339	Time at which the cluster was originally created.
`disk_usage`		`object` of type `ClusterDiskUsageobject`	Contains information on the cluster's current disk usage. This data is collected about once a day, and isn't guaranteed to be perfectly fresh. For a new cluster, it may also not have been collected yet at all, in which case this field will be `null`.
`environment`	✔	enum `string`	The type of environment which the cluster belongs to. This is largely for informational purposes, but may affect the cluster's display and interaction from Bridge tools. For example, a value of `production` will show a special banner to indicate the higher risk environment. Enum `production`.
`host`		`string`	The hostname of the cluster.
`is_ha`		`boolean`	Whether the cluster is high availability, meaning that it has a secondary it can fail over to quickly in case the primary becomes unavailable.
`is_protected`		`boolean`	Whether the cluster is protected. Protected clusters can't be destroyed until their protected flag is removed (which can be done via the "update cluster" endpoint).
`is_suspended`		`boolean`	Indicates whether the cluster is currently in a suspended state, meaning that while its disk is available, it doesn't currently have a running virtual machine.
`keychain_id`	✔	`string` in EID format	The ID of the keychain used by the cluster for encrypting its data.
`maintenance_window_start`	✔	`integer`	The hour of day which a maintenance window can possibly start. This should be an integer from `0` to `23` representing the hour of day which maintenance is allowed to start, with `0` representing midnight UTC. Maintenance windows are typically three hours long starting from this hour. A `null` value means that no explicit maintenance window has been set and that maintenance is allowed to occur at any time.
`major_version`		`integer`	The cluster's major Postgres version. For example, `14`.
`memory`		`number`	The total amount of memory available on the cluster's instance in GB (gigabytes). This is normally a whole integer, but may be fractional for the case of smaller hobby instances that have less than a gigabyte of memory.
`name`		`string`	A human-readable name for the cluster.
`network_id`	✔	`string` in EID format	The ID of the network where the cluster is located.
`parent_id`	✔	`string` in EID format	The ID of the primary or parent cluster for a replica cluster. Always `null` for primaries and forks.
`plan_id`		`string`	The ID of the cluster's plan. Determines instance, CPU, and memory.
`postgres_version_id`		`string` in EID format	The ID of the cluster's major Postgres version.
`provider_id`	✔	enum `string`	The cloud provider where the cluster is located. Enum `aws`, `azure`, or `gcp`.
`region_id`		`string`	The provider region where the cluster is located.
`replicas`		`array` of `array`	Replicas for the cluster.
`reset_stats_weekly`		`boolean`	Whether `pg_stat_statements` is automatically reset on the cluster on a weekly basis.
`storage`		`integer`	The amount of storage available to the cluster in GB (gigabytes).
`tailscale_active`		`boolean`	Indicates whether tailscale is active for the cluster.
`team_id`		`string` in EID format	The ID of the team that the cluster belongs to.
`updated_at`		`string` of date/time formatted as RFC 3339	Time at which the cluster was last updated.
`cluster_id`	✔	`string` in EID format	In the case of a replica, the ID of the primary cluster. Always `null` for primaries and forks. Deprecated Prefer use of `parent_id`.

Create cluster fork

Create a fork of an existing database cluster.

Note that target_time must be between the cluster's oldest backup (see oldest_backup_at under cluster status) and the current time. Clusters can't be forked until an initial backup has been captured for them. This will occur shortly after they're created, but a brand new cluster may not be available for forking right away.

POST /clusters/{cluster_id}/forks

Request

Path parameters

cluster_id: The ID of the cluster to fork.

Request body schema

Content type: application/json

Name	Required	Type	Description
`name`	✔	`string`	A human-readable name for the fork.
`is_ha`		`boolean`	Whether the fork should be high availability, meaning that it has a secondary it can fail over to quickly in case the primary becomes unavailable.
`keychain_id`		`string` in EID format	The ID of the keychain that should be used by the fork for encrypting its data.
`network_id`		`string` in EID format	The ID of the network where the new fork should be created. If not specified, the cluster is created in a new network.
`plan_id`		`string`	The ID of the plan with which to create the fork. Determines instance, CPU, and memory. If not specified, defaults to the target cluster's plan.
`provider_id`		enum `string`	The cloud provider in which to create the fork. If not specified, defaults to the target cluster's provider. If specified, then `plan_id` and `region_id` must also be specified. Enum `aws`, `azure`, or `gcp`.

Connect to a Tailscale network

Connects a cluster to a Tailscale network (tailnet) similarly to having run tailscale up.

The request takes a Tailscale auth key to authorize the request, which can be generated from Tailscale's keys page if you are a network admin. Auth keys are only persisted in Bridge only as long as needed to be handed off to target Postgres servers, and are encrypted during that period. Even so, given their sensitivity, we still recommend generating a short-lived one to minimize the risk of accidental exposure.

We also encourage you to provision an auth key with an ACL tag like crunchy that an admin has preconfigured with desired access permissions. By doing so, the cluster's permissions will be limited to those specified by the tag immediately on joining your tailnet.

See the Tailscale docs on tailnets for more information.
