- DESCRIPTION
- Update cluster settings for an existing container cluster.
- EXAMPLES
-
To enable autoscaling for an existing cluster, run:
gcloud container clusters update sample-cluster --enable-autoscaling - POSITIONAL ARGUMENTS
-
NAME- The name of the cluster to update.
- REQUIRED FLAGS
-
-
Exactly one of these must be specified:
--autoprovisioning-cgroup-mode=AUTOPROVISIONING_CGROUP_MODE-
Sets the cgroup mode for auto-provisioned nodes.
Updating this flag triggers an update using surge upgrades of all existing auto-provisioned nodes to apply the new value of cgroup mode.
For an Autopilot cluster, the specified cgroup mode will be set on all existing and new nodes in the cluster. For a Standard cluster, the specified cgroup mode will be set on all existing and new auto-provisioned node pools in the cluster.
If not set, GKE uses cgroupv2 for new nodes when the cluster was created running 1.26 or later, and cgroupv1 for clusters created running 1.25 or earlier. To check your initial cluster version, run
gcloud container clusters describe [NAME] --format="value(initialClusterVersion)"For clusters created running version 1.26 or later, you can't set the cgroup mode to v1.
To learn more, see: https://cloud.google.com/kubernetes-engine/docs/how-to/migrate-cgroupv2.
AUTOPROVISIONING_CGROUP_MODEmust be one of:default,v1,v2. --autoprovisioning-enable-insecure-kubelet-readonly-port-
Enables the Kubelet's insecure read only port for Autoprovisioned Node Pools.
If not set, the value from nodePoolDefaults.nodeConfigDefaults will be used.
To disable the readonly port
--no-autoprovisioning-enable-insecure-kubelet-readonly-port. -
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 container clusters update example-cluster --autoprovisioning-network-tags=tag1,tag2New 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.
-
For an Autopilot cluster, the specified comma-separated resource manager tags
that has the GCP_FIREWALL purpose replace the existing tags on all nodes in the
cluster.
For a Standard cluster, the specified comma-separated resource manager tags that has the GCE_FIREWALL purpose are applied to all nodes in the new newly created auto-provisioned node pools. Existing auto-provisioned node pools retain the tags that they had before the update. To update tags on an existing auto-provisioned node pool, use the node pool level flag '--resource-manager-tags'.
Examples:
gcloud container clusters update example-cluster --autoprovisioning-resource-manager-tags=tagKeys/1234=tagValues/2345gcloud container clusters update example-cluster --autoprovisioning-resource-manager-tags=my-project/key1=value1gcloud container clusters update example-cluster --autoprovisioning-resource-manager-tags=12345/key1=value1,23456/key2=value2gcloud container clusters update example-cluster --autoprovisioning-resource-manager-tags=All nodes in an Autopilot cluster or all newly created auto-provisioned nodes in a Standard cluster, including nodes that are resized or re-created, will have the specified tags on the corresponding Instance object in the Compute Engine API. You can reference these tags in network firewall policy rules. For instructions, see https://cloud.google.com/firewall/docs/use-tags-for-firewalls.
--autoscaling-profile=AUTOSCALING_PROFILE- Set autoscaling behaviour, choices are 'optimize-utilization' and 'balanced'. Default is 'balanced'.
--clear-fleet-project- Remove the cluster from current fleet host project. Example: $ gcloud container clusters update --clear-fleet-project
--complete-credential-rotation-
Complete the IP and credential rotation for this cluster. For example:
gcloud container clusters update example-cluster --complete-credential-rotationThis 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 container clusters update example-cluster --complete-ip-rotationThis 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.
--containerd-config-from-file=PATH_TO_FILE-
Path of the YAML file that contains containerd configuration entries like
configuring access to private image registries.
For detailed information on the configuration usage, please refer to https://cloud.google.com/kubernetes-engine/docs/how-to/customize-containerd-configuration.
Note: Updating the containerd configuration of an existing cluster or node pool requires recreation of the existing nodes, which might cause disruptions in running workloads.
Use a full or relative path to a local file containing the value of containerd_config.
--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.
--[no-]enable-cilium-clusterwide-network-policy-
Enable Cilium Clusterwide Network Policies on the cluster. Use
--enable-cilium-clusterwide-network-policyto enable and--no-enable-cilium-clusterwide-network-policyto disable. --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-fleet-
Set cluster project as the fleet host project. This will register the cluster to
the same project. To register the cluster to a fleet in a different project,
please use
--fleet-project=FLEET_HOST_PROJECT. Example: $ gcloud container clusters update --enable-fleet --enable-fqdn-network-policy- Enable FQDN Network Policies on the cluster. FQDN Network Policies are disabled by default.
--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-insecure-kubelet-readonly-port-
Enables the Kubelet's insecure read only port.
To disable the readonly port on a cluster or node-pool set the flag to
--no-enable-insecure-kubelet-readonly-port. --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-kubernetes-unstable-apis=API,[API,…]- Enable Kubernetes beta API features on this cluster. Beta APIs are not expected to be production ready and should be avoided in production-grade environments.
--enable-l4-ilb-subsetting- Enable Subsetting for L4 ILB services created on this cluster.
-
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-multi-networking- Enables multi-networking on the cluster. Multi-networking is disabled by default.
--enable-network-policy- Enable network policy enforcement for this cluster. If you are enabling network policy on an existing cluster the network policy addon must first be enabled on the master by using --update-addons=NetworkPolicy=ENABLED flag.
--enable-private-nodes-
Standard cluster: Enable private nodes as a default behavior for all newly
created node pools, if
--enable-private-nodesis not provided at node pool creation time.Modifications to this flag do not affect `--enable-private-nodes` state of the existing node pools.
Autopilot cluster: Force new and existing workloads, without explicit
cloud.google.com/private-node=truenode selector, to run on nodes with no public IP address.Modifications to this flag trigger a re-schedule operation on all existng workloads to run on different node VMs.
--[no-]enable-ray-cluster-logging-
Enable automatic log processing sidecar for Ray clusters. Use
--enable-ray-cluster-loggingto enable and--no-enable-ray-cluster-loggingto disable. --[no-]enable-ray-cluster-monitoring-
Enable automatic metrics collection for Ray clusters. Use
--enable-ray-cluster-monitoringto enable and--no-enable-ray-cluster-monitoringto disable. --enable-secret-manager-
Enables the Secret Manager CSI driver provider component. See https://secrets-store-csi-driver.sigs.k8s.io/introduction
https://github.com/GoogleCloudPlatform/secrets-store-csi-driver-provider-gcp
To disable in an existing cluster, explicitly set flag to --no-enable-secret-manager
--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-kubernetesflag is deprecated and will be removed in an upcoming release. Please use--loggingand--monitoringinstead. For more information, please read: https://cloud.google.com/kubernetes-engine/docs/concepts/about-logs and https://cloud.google.com/kubernetes-engine/docs/how-to/configure-metrics. -
