this can do it nicely.

+Subject: [PATCH] kubeconfig: don't store absolute path to gcloud binary
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The `gcloud beta container clusters get-credentials $cluster \
+--region $region --project $project`
+command can be used to write kubectl config files.
+
+In that file, normally the absolute path to the `gcloud` binary is
+stored.
+
+This is a bad idea in NixOS. We might eventually garbage-collect that
+specific gcloud binary - and in general, would expect a nix-shell
+provided gcloud to be used.
+
+In its current state, token renewal would just start to break with the
+following error message:
+
+Unable to connect to the server: error executing access token command "/nix/store/…/gcloud config config-helper --format=json": err=fork/exec /nix/store/…/gcloud: no such file or directory output= stderr=
+
+Avoid this by storing just `gcloud` inside `cmd-path`, which causes
+kubectl to lookup the gcloud command from $PATH, which is more likely to
+keep working.
