Updates a cluster within an instance. Note that UpdateCluster does not support updating cluster_config.cluster_autoscaling_config. In order to update it, you must use PartialUpdateCluster.

Scopes

You will need authorization for at least one of the following scopes to make a valid call:

• https://www.googleapis.com/auth/bigtable.admin
• https://www.googleapis.com/auth/bigtable.admin.cluster
• https://www.googleapis.com/auth/bigtable.admin.instance
• https://www.googleapis.com/auth/cloud-bigtable.admin
• https://www.googleapis.com/auth/cloud-bigtable.admin.cluster
• https://www.googleapis.com/auth/cloud-platform

If unset, the scope for this method defaults to https://www.googleapis.com/auth/bigtable.admin. You can set the scope for this method like this: bigtableadmin2 --scope <scope> projects instances-clusters-update ...

Required Scalar Argument

• <name> (string)
  • The unique name of the cluster. Values are of the form projects/{project}/instances/{instance}/clusters/a-z*.

Required Request Value

The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure. In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.

For example, a structure like this:

Cluster:
  cluster-config:
    cluster-autoscaling-config:
      autoscaling-limits:
        max-serve-nodes: integer
        min-serve-nodes: integer
      autoscaling-targets:
        cpu-utilization-percent: integer
        storage-utilization-gib-per-node: integer
  default-storage-type: string
  encryption-config:
    kms-key-name: string
  location: string
  name: string
  serve-nodes: integer
  state: string

can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.

• -r .cluster-config.cluster-autoscaling-config.autoscaling-limits max-serve-nodes=95
  • Required. Maximum number of nodes to scale up to.

• min-serve-nodes=72

  • Required. Minimum number of nodes to scale down to.

• ..autoscaling-targets cpu-utilization-percent=40

  • The cpu utilization that the Autoscaler should be trying to achieve. This number is on a scale from 0 (no utilization) to 100 (total utilization), and is limited between 10 and 80, otherwise it will return INVALID_ARGUMENT error.

• storage-utilization-gib-per-node=1

  • The storage utilization that the Autoscaler should be trying to achieve. This number is limited between 2560 (2.5TiB) and 5120 (5TiB) for a SSD cluster and between 8192 (8TiB) and 16384 (16TiB) for an HDD cluster, otherwise it will return INVALID_ARGUMENT error. If this value is set to 0, it will be treated as if it were set to the default value: 2560 for SSD, 8192 for HDD.

• .... default-storage-type=accusam

  • Immutable. The type of storage used by this cluster to serve its parent instance's tables, unless explicitly overridden.

• encryption-config kms-key-name=takimata

  • Describes the Cloud KMS encryption key that will be used to protect the destination Bigtable cluster. The requirements for this key are: 1) The Cloud Bigtable service account associated with the project that contains this cluster must be granted the cloudkms.cryptoKeyEncrypterDecrypter role on the CMEK key. 2) Only regional keys can be used and the region of the CMEK key must match the region of the cluster. Values are of the form projects/{project}/locations/{location}/keyRings/{keyring}/cryptoKeys/{key}

• .. location=consetetur

  • Immutable. The location where this cluster's nodes and storage reside. For best performance, clients should be located as close as possible to this cluster. Currently only zones are supported, so values should be of the form projects/{project}/locations/{zone}.
• name=voluptua.
  • The unique name of the cluster. Values are of the form projects/{project}/instances/{instance}/clusters/a-z*.
• serve-nodes=29
  • The number of nodes in the cluster. If no value is set, Cloud Bigtable automatically allocates nodes based on your data footprint and optimized for 50% storage utilization.
• state=erat
  • Output only. The current state of the cluster.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

• The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
• The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
• You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
• You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

• -o out
  • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional General Properties

The following properties can configure any call, and are not specific to this method.

• -p $-xgafv=string

  • V1 error format.

• -p access-token=string

  • OAuth access token.

• -p alt=string

  • Data format for response.

• -p callback=string

  • JSONP

• -p fields=string

  • Selector specifying which fields to include in a partial response.

• -p key=string

  • API key. Your API key identifies your project and provides you with API access, quota, and reports. Required unless you provide an OAuth 2.0 token.

• -p oauth-token=string

  • OAuth 2.0 token for the current user.

• -p pretty-print=boolean

  • Returns response with indentations and line breaks.

• -p quota-user=string

  • Available to use for quota purposes for server-side applications. Can be any arbitrary string assigned to a user, but should not exceed 40 characters.

• -p upload-type=string

  • Legacy upload protocol for media (e.g. "media", "multipart").

• -p upload-protocol=string

  • Upload protocol for media (e.g. "raw", "multipart").
