How to Obtain Kubernetes Credentials for a GKE Cluster Using the Go SDK?

Retrieving Kubernetes Credentials from GKE Cluster Using Go SDK

Question:

Can the Google Cloud SDK's gcloud container clusters get-credentials command be replicated using the Go SDK?

Context:

After creating a GKE cluster via the Google Cloud SDK, the get-credentials command provides a kubeconfig file to establish connections to the cluster. However, this command is not directly available in the Go SDK.

Answer:

Limitations of Go SDK:

The GKE API currently does not offer an equivalent endpoint to directly retrieve a kubeconfig file. The logic for parsing cluster configuration and generating the kubeconfig is handled within the Python-based gcloud tooling.

Approaches:

• Manual Implementation: You can create your own Go function to parse the cluster configuration (obtained via the func (r *ProjectsZonesClustersService) Get() method) and construct the corresponding kubeconfig file.
• kubectl Integration: Consider utilizing the kubectl config set-credentials command within your Go program. This involves using the kubectl binary as an external process or importing the relevant libraries from the kubectl source code.

Conclusion:

While the Go SDK does not directly provide an exact equivalent of gcloud container clusters get-credentials, the suggested approaches allow you to obtain the kubeconfig for your GKE cluster programmatically using the Go language.
