How to remove "the gcp auth plugin is deprecated in v1.22+"

Problem

• Everytime we run the kubectl or helm commands, you’d get this warning:

➜  ~ kubectl get po
W0511 14:48:33.482892   92730 gcp.go:119] WARNING: the gcp auth plugin is deprecated in v1.22+, unavailable in v1.26+; use gcloud instead.

Solutions: 3 steps

See this

1. Install gke-gcloud-auth-plugin

gcloud components install gke-gcloud-auth-plugin

To verify if it’s installed properly.

➜  ~ gke-gcloud-auth-plugin --version
Kubernetes v1.26.2-alpha+038d2342e9672c4772e9ee48a3f1dd9438156eba

2. Add the environment varialbe in your shell. Add this block in .zshrc or .bashrc

export USE_GKE_GCLOUD_AUTH_PLUGIN=True

3. Update the configuration for the cluster

gcloud container clusters get-credentials CLUSTER_NAME

If you have dev, stage and prod environment, we’d have to run it in all environments

➜  ~ gcloud projects list
PROJECT_ID      NAME            PROJECT_NUMBER
mycom-dev        mycom-dev        268984123123
mycom-prod       mycom-prod       272871231238
mycom-stage      mycom-stage      921231231276

➜  ~ gcloud config set project mycom-dev
Updated property [core/project].

➜  ~ gcloud container clusters list
NAME                      LOCATION         MASTER_VERSION   MASTER_IP      MACHINE_TYPE    NODE_VERSION      NUM_NODES  STATUS

➜  ~ gcloud container clusters get-credentials mycom-dev-us-central1

Repeat this for stage and prod
