Configures kubectl so that you can connect to an Amazon EKS cluster.
This command constructs a configuration with prepopulated server and certificate authority data values for a specified cluster.
You can specify an IAM role ARN with the –role-arn option to use for authentication when you issue kubectl commands.
Otherwise, the IAM entity in your default AWS CLI or SDK credential chain is used.
You can view your default AWS CLI or SDK identity by running the
aws sts get-caller-identity command.
The resulting kubeconfig is created as a new file or merged with an existing kubeconfig file using the following logic:
You can use the –dry-run option to print the resulting configuration to stdout instead of writing it to the specified location.
update-kubeconfig --name <value> [--kubeconfig <value>] [--role-arn <value>] [--dry-run] [--verbose] [--alias <value>] [--user-alias <value>] [--debug] [--endpoint-url <value>] [--no-verify-ssl] [--no-paginate] [--output <value>] [--query <value>] [--profile <value>] [--region <value>] [--version <value>] [--color <value>] [--no-sign-request] [--ca-bundle <value>] [--cli-read-timeout <value>] [--cli-connect-timeout <value>] [--cli-binary-format <value>] [--no-cli-pager] [--cli-auto-prompt] [--no-cli-auto-prompt]
The name of the cluster for which to create a kubeconfig entry. This cluster must exist in your account and in the specified or configured default Region for your AWS CLI installation.
Optionally specify a kubeconfig file to append with your configuration. By default, the configuration is written to the first file path in the KUBECONFIG environment variable (if it is set) or the default kubeconfig path (.kube/config) in your home directory.
To assume a role for cluster authentication, specify an IAM role ARN with this option. For example, if you created a cluster while assuming an IAM role, then you must also assume that role to connect to the cluster the first time.
Print the merged kubeconfig to stdout instead of writing it to the specified file.
Print more detailed output when writing to the kubeconfig file, including the appended entries.
Alias for the cluster context name. Defaults to match cluster ARN.
Alias for the generated user name. Defaults to match cluster ARN.
Turn on debug logging.
Override command’s default URL with the given URL.
By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.
Disable automatic pagination.
The formatting style for command output.
A JMESPath query to use in filtering the response data.
Use a specific profile from your credential file.
The region to use. Overrides config/env settings.
Display the version of this tool.
Turn on/off color output.
Do not sign requests. Credentials will not be loaded if this argument is provided.
The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.
The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.
The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.
The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob
fileb:// will always be treated as binary and use the file contents directly regardless of the
cli-binary-format setting. When using
file:// the file contents will need to properly formatted for the configured
Disable cli pager for output.
Automatically prompt for CLI input parameters.
Disable automatically prompt for CLI input parameters.
To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.
Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
To update a kubeconfig for your cluster
This example command updates the default kubeconfig file to use your cluster as the current context.
aws eks update-kubeconfig --name example
Added new context arn:aws:eks:us-west-2:012345678910:cluster/example to /Users/ericn/.kube/config
