The product described by this documentation, Anthos Clusters on AWS (previous generation), is now in maintenance mode. All new installs must use the current generation product, Anthos clusters on AWS.

Anthos-gke aws clusters

Stay organized with collections Save and categorize content based on your preferences.

The commands in anthos-gke aws clusters operate on Anthos clusters on AWS (GKE on AWS) user clusters. You authenticate to your user clusters with the get-credentials command. You can also gather additional information for debugging with the diagnose command.

Get-credentials

The get-credentials command updates a kubeconfig file with credentials and endpoint information for a Anthos clusters on AWS user cluster. By default, credentials are appended to ~/.kube/config. If you set the KUBECONFIG environment variable to another file path, anthos-gke appends credentials to that file.

anthos-gke aws clusters get-credentials NAME [--workspace DIRECTORY]

Positional arguments

NAME
Name of the cluster that anthos-gke generates credentials for. The name should match the metadata.name field of the AWSCluster resource.

Optional flags

--workspace [DIRECTORY]
An optional argument for the directory containing the anthos-gke.yaml file. Defaults to the current directory.

Examples

To get credentials for a cluster called cluster-0 defined in the current working directory, run the following command:

anthos-gke aws clusters get-credentials cluster-0

Diagnose

The diagnose snapshot command generates a support bundle to help Google Cloud support debug issues with your user clusters. The support bundle is a tar file which includes configuration, cluster events, and logs. Send this file to your technical support manager.

anthos-gke aws clusters diagnose snapshot CLUSTER_NAME
           --ssh-key-path PATH
           [--bastion-ip IP]
           [--bastion-ssh-key-path PATH]
           [--cluster-ssh-key-path PATH]
           [--dry-run]
           [--mgmt-service-ssh-key-path PATH]
           [--nodepool-ssh-key-path PATH]
           [--output PATH]
           [--quiet]
           [--snapshot-config PATH]
           [--workspace DIRECTORY]

Positional arguments

CLUSTER_NAME
Name of the cluster to generate a support bundle for. This value should match the metadata.name field of your AWSCluster.

Flags

--ssh-key-path PATH
A required argument which gives the path to an SSH key file. If you created a key with anthos-gke management init, this value is ~/.ssh/anthos-gke.

Optional flags

[--bastion-ip IP]
An override for the bastion host IP address in the current workspace.
[--bastion-ssh-key-path PATH]
A specific SSH key file for the bastion host. Defaults to --ssh-key-path.
[--cluster-ssh-key-path PATH]
A specific SSH key file for the workload cluster control plane machines. Defaults to --ssh-key-path.
[--dry-run]
An option to display the snapshot configuration file without generating a support bundle.
[--mgmt-service-ssh-key-path PATH]
A specific SSH key file for the management service. Defaults to --ssh-key-path.
[--nodepool-ssh-key-path PATH]
A specific SSH key file for node pool machines. Defaults to --ssh-key-path.
[--output PATH]
A file path for the support bundle tarball.
[--quiet]
An option to eliminate messages printed to the console.
[--snapshot-config PATH]
The path to a YAML snapshot configuration file (optional).
[--workspace DIR]
Workspace directory which should contain the anthos-gke.yaml configuration file. Defaults to the current directory.

Examples

To generate a support bundle for a workload cluster named cluster-0, run the following command:

anthos-gke aws clusters diagnose snapshot cluster-0 \
             --ssh-key-path ~/.ssh/anthos-gke \
             --workspace ~/example/workspace

To view the default snapshot configuration, run the following command:

anthos-gke aws clusters diagnose snapshot cluster-0 \
             --ssh-key-path ~/.ssh/anthos-gke \
             --dry-run

To specify a custom snapshot configuration file (including your own bash and kubectl commands), run the following command:

anthos-gke aws clusters diagnose snapshot cluster-0 \
             --ssh-key-path ~/.ssh/anthos-gke
             --snapshot-config ~/my-snapshot-config.yaml
