error: You must be logged in to the server (the server has asked for the client to provide credentials)

Since this morning we get these errors when trying to use kubectl from this container:

$ echo $SERVICE_ACCOUNT_JSON > key-file.json
$ gcloud auth activate-service-account --key-file key-file.json --project application-europe
Activated service account credentials for: [deployment-from-gitlab@application-europe.iam.gserviceaccount.com]
$ gcloud container clusters get-credentials application-beta --zone europe-west1-d
Fetching cluster endpoint and auth data.
kubeconfig entry generated for application-beta.
$ kubectl replace -f application-webapp-frontend-deployment.yml
error: You must be logged in to the server (the server has asked for the client to provide credentials)

Could this be because of an update of this docker image?

A solution is to add:

gcloud config set container/use_client_certificate True

I'm no sure why this is needed now, but at least it works.
