(BETA) Update cluster settings for an existing container cluster.
To enable autoscaling for an existing cluster, run:
$ gcloud beta container clusters update sample-cluster \ --enable-autoscaling
- NAME
The name of the cluster to update.
- Exactly one of these must be specified:
- --autoprovisioning-network-tags=[TAGS,...]
Replaces the user specified Compute Engine tags on all nodes in all the existing auto-provisioned node pools in the Standard cluster or the Autopilot with the given tags (comma separated).
Examples:
$ gcloud beta container clusters update example-cluster \ --autoprovisioning-network-tags=tag1,tag2
New nodes in auto-provisioned node pools, including ones created by resize or recreate, will have these tags on the Compute Engine API instance object and these tags can be used in firewall rules. See https://cloud.google.com/sdk/gcloud/reference/compute/firewall-rules/create for examples.
- --autoscaling-profile=AUTOSCALING_PROFILE
Set autoscaling behaviour, choices are 'optimize-utilization' and 'balanced'. Default is 'balanced'.
- --complete-credential-rotation
Complete the IP and credential rotation for this cluster. For example:
$ gcloud beta container clusters update example-cluster \ --complete-credential-rotation
This causes the cluster to stop serving its old IP, return to a single IP, and invalidate old credentials. See documentation for more details: https://cloud.google.com/kubernetes-engine/docs/how-to/credential-rotation.
- --complete-ip-rotation
Complete the IP rotation for this cluster. For example:
$ gcloud beta container clusters update example-cluster \ --complete-ip-rotation
This causes the cluster to stop serving its old IP, and return to a single IP state. See documentation for more details: https://cloud.google.com/kubernetes-engine/docs/how-to/ip-rotation.
- --database-encryption-key=DATABASE_ENCRYPTION_KEY
Enable Database Encryption.
Enable database encryption that will be used to encrypt Kubernetes Secrets at the application layer. The key provided should be the resource ID in the format of projects/[KEY_PROJECT_ID]/locations/[LOCATION]/keyRings/[RING_NAME]/cryptoKeys/[KEY_NAME]. For more information, see https://cloud.google.com/kubernetes-engine/docs/how-to/encrypting-secrets.
- --disable-database-encryption
Disable database encryption.
Disable Database Encryption which encrypt Kubernetes Secrets at the application layer. For more information, see https://cloud.google.com/kubernetes-engine/docs/how-to/encrypting-secrets.
- --disable-default-snat
Disable default source NAT rules applied in cluster nodes.
By default, cluster nodes perform source network address translation (SNAT) for packets sent from Pod IP address sources to destination IP addresses that are not in the non-masquerade CIDRs list. For more details about SNAT and IP masquerading, see: https://cloud.google.com/kubernetes-engine/docs/how-to/ip-masquerade-agent#how_ipmasq_works SNAT changes the packet's source IP address to the node's internal IP address.
When this flag is set, GKE does not perform SNAT for packets sent to any destination. You must set this flag if the cluster uses privately reused public IPs.
The --disable-default-snat flag is only applicable to private GKE clusters, which are inherently VPC-native. Thus, --disable-default-snat requires that the cluster was created with both --enable-ip-alias and --enable-private-nodes.
- --disable-workload-identity
Disable Workload Identity on the cluster.
For more information on Workload Identity, see
https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity
- --enable-autoscaling
Enables autoscaling for a node pool.
Enables autoscaling in the node pool specified by --node-pool or the default node pool if --node-pool is not provided. If not already, --max-nodes or --total-max-nodes must also be set.
- --enable-cost-allocation
Enable the cost management feature.
When enabled, you can get informational GKE cost breakdowns by cluster, namespace and label in your billing data exported to BigQuery https://cloud.google.com/billing/docs/how-to/export-data-bigquery.
Use --no-enable-cost-allocation to disable this feature.
- --enable-gke-oidc
(DEPRECATED) Enable GKE OIDC authentication on the cluster.
When enabled, users would be able to authenticate to Kubernetes cluster after properly setting OIDC config.
GKE OIDC is by default disabled when creating a new cluster. To disable GKE OIDC in an existing cluster, explicitly set flag --no-enable-gke-oidc.
GKE OIDC is being replaced by Identity Service across Anthos and GKE. Thus, flag --enable-gke-oidc is also deprecated. Please use --enable-identity-service to enable the Identity Service component
- --enable-google-cloud-access
When you enable Google Cloud Access, any public IP addresses owned by Google Cloud can reach the public control plane endpoint of your cluster.
- --enable-identity-service
Enable Identity Service component on the cluster.
When enabled, users can authenticate to Kubernetes cluster with external identity providers.
Identity Service is by default disabled when creating a new cluster. To disable Identity Service in an existing cluster, explicitly set flag --no-enable-identity-service.
- --enable-image-streaming
Specifies whether to enable image streaming on cluster.
- --enable-intra-node-visibility
Enable Intra-node visibility for this cluster.
Enabling intra-node visibility makes your intra-node pod-to-pod traffic visible to the networking fabric. With this feature, you can use VPC flow logging or other VPC features for intra-node traffic.
Enabling it on an existing cluster causes the cluster master and the cluster nodes to restart, which might cause a disruption.
- --enable-l4-ilb-subsetting
Enable Subsetting for L4 ILB services created on this cluster.
- --enable-legacy-authorization
Enables the legacy ABAC authentication for the cluster. User rights are granted through the use of policies which combine attributes together. For a detailed look at these properties and related formats, see https://kubernetes.io/docs/admin/authorization/abac/. To use RBAC permissions instead, create or update your cluster with the option --no-enable-legacy-authorization.
- --enable-logging-monitoring-system-only
(DEPRECATED) Enable Cloud Operations system-only monitoring and logging.
The --enable-logging-monitoring-system-only flag is deprecated and will be removed in an upcoming release. Please use --logging and --monitoring instead. For more information, please read: https://cloud.google.com/stackdriver/docs/solutions/gke/installing.
- --enable-master-authorized-networks
Allow only specified set of CIDR blocks (specified by the --master-authorized-networks flag) to connect to Kubernetes master through HTTPS. Besides these blocks, the following have access as well:
1) The private network the cluster connects to if `--enable-private-nodes` is specified. 2) Google Compute Engine Public IPs if `--enable-private-nodes` is not specified.
Use --no-enable-master-authorized-networks to disable. When disabled, public internet (0.0.0.0/0) is allowed to connect to Kubernetes master through HTTPS.
- --enable-master-global-access
Use with private clusters to allow access to the master's private endpoint from any Google Cloud region or on-premises environment regardless of the private cluster's region.
- --enable-network-policy

- --enable-pod-security-policy
Enables the pod security policy admission controller for the cluster. The pod security policy admission controller adds fine-grained pod create and update authorization controls through the PodSecurityPolicy API objects. For more information, see https://cloud.google.com/kubernetes-engine/docs/how-to/pod-security-policies.
- --enable-private-endpoint
Enables cluster's control plane to be accessible using private IP address only.
- --enable-service-externalips
Enables use of services with externalIPs field.
- --enable-shielded-nodes
Enable Shielded Nodes for this cluster. Enabling Shielded Nodes will enable a more secure Node credential bootstrapping implementation. Starting with version 1.18, clusters will have Shielded GKE nodes by default.
- --enable-stackdriver-kubernetes
(DEPRECATED) Enable Cloud Operations for GKE.
The --enable-stackdriver-kubernetes flag is deprecated and will be removed in an upcoming release. Please use --logging and --monitoring instead. For more information, please read: https://cloud.google.com/stackdriver/docs/solutions/gke/installing.
