Detailed Feature Information
Which builder is relevant to this request? kubectl
Is your feature request related to a problem? Please describe. My Cloud Build Private Pool requires direct access to GKE private cluster's control plane using its private IP for CD pipeline configuration. (VPN Tunneling has been enabled already according to the guide https://cloud.google.com/architecture/accessing-private-gke-clusters-with-cloud-build-private-pools. However, current kubectl build does not provide any way to add '--internal-ip' flag when cluster credential is fetched.
Describe the solution you'd like Example: Add an environment variable which indicates the setting of '--internal-ip' flag. If I set that env variable is true, then '--internal-ip' flag is added during fetching cluster credentials as below.
gcloud container clusters get-credentials --internal-ip --zone "$CLOUDSDK_COMPUTE_ZONE" "$CLOUDSDK_CONTAINER_CLUSTER"
Describe alternatives you've considered
Additional context In kubectl.bash, following lines may be modified.
if [ -n "$region" ]; then echoerr "Running: gcloud container clusters get-credentials --project="$project" --region="$region" "$cluster"" gcloud container clusters get-credentials --project="$project" --region="$region" "$cluster" || exit else echoerr "Running: gcloud container clusters get-credentials --project="$project" --zone="$zone" "$cluster"" gcloud container clusters get-credentials --project="$project" --zone="$zone" "$cluster" || exit fi
