Container Service for Kubernetes:DescribeClusterUserKubeconfig

Last Updated:Feb 29, 2024

Kubeconfig files store identity and authentication information that is used by clients to access Container Service for Kubernetes (ACK) clusters. To use a kubectl client to manage an ACK cluster, you need to use the corresponding kubeconfig file to connect to the ACK cluster. We recommend that you keep kubeconfig files confidential and revoke kubeconfig files that are not in use. This helps prevent data leaks caused by the disclosure of kubeconfig files.

Operation description

**

****The default validity period of a kubeconfig file is 3 years. Two months before a kubeconfig file expires, you can renew it in the Container Service for Kubernetes (ACK) console or by calling API operations. After a kubeconfig file is renewed, the secret is valid for 3 years. The previous kubeconfig secret remains valid until expiration. We recommend that you renew your kubeconfig file at the earliest opportunity.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
