`docker-credential-gcloud` not in system PATH

docker, gcloud, google-cloud-platform, google-container-registry, google-kubernetes-engine

Solution

Notice: All `docker-credential-gcr` below can be replaced with `docker-credential-gcloud`. I think it is just different versions of gcloud, I might be wrong.

I used Homebrew Cask to install gcloud too. I installed `docker-credential-gcr` with

$ gcloud components install docker-credential-gcr

And then like you said, `which docker-credential-gcr` doesn't gave you anything.

So I ran `which gcloud` to find there is a symlink to gcloud in `/usr/local/bin`. This symlink is created by Homebrew when you installed gcloud at first place. Now `docker-credential-gcr` wasn't installed by Homebrew but by gcloud itself, so there isn't a symlink.

I called `readlink /usr/local/bin/gcloud` and found out gcloud is installed in `/usr/local/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/bin/`.

Then:

$ ls /usr/local/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/bin

There you should see `docker-credential-gcr` listed there.

I simply linked it to `/usr/local/bin`:

$ ln -s \
    /usr/local/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/bin/docker-credential-gcr \
    /usr/local/bin/

Then run:

$ docker-credential-gcr configure-docker

It should succeed.

Problem

After the latest updates to gcloud and docker I'm unable to access images on my google container repository. Locally when I run: `gcloud auth configure-docker` as per the instructions after updating gcloud, I get the following message: ``` WARNING: `docker-credential-gcloud` not in system PATH. gcloud's Docker credential helper can be configured but it will not work until this is corrected. gcloud credential helpers already registered correctly. ``` Running `which docker-credential-gcloud` returns `docker-credential-gcloud not found`. I have no other gcloud-related path issues and for the life of me can't figure out how to install/add docker-credential-gcloud to path. Here's what I have installed (shown via `gcloud version`): ``` Google Cloud SDK 197.0.0 beta 2017.09.15 bq 2.0.31 container-builder-local core 2018.04.06 docker-credential-gcr gsutil 4.30 ``` I also have Docker CE Version 18.03.0-ce-mac60 (23751). Here's my $PATH:`/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin` I also ran `source /usr/local/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/path.zsh.inc` on original gcloud install.
