Why Cargo requires docker-credentials-gcloud?

[djivko]

Trying to do
gefyra up

fails with error:
[CRITICAL] There was an error running Gefyra: docker-credential-gcloud not installed or not available in PATH

I am trying to understand why it's needed?

P.S. Probably it's good to document that requirement.

Hi @djivko
Thank you for bringing this up.

I am a bit surprised about this error message, too. From a code perspective docker-credential-gcloud is actually not a dependency.

A dedicated Cargo Docker image is built each time you run gefyra up (compiling the VPN secrets). That's why a docker build operation is performed under the hood.
I wonder if you are able to build other Docker images on your machine? Is the gcloud CLI installed to your system?

[Schille]

🤔 It's not needed, and I cannot find the component which by far could cause this requirement.
I checked the Docker images, there is none pulled from the Google Container Registry (i.e. gcr.io) in Gefyra client.
I am going to check the Docker API package to find out more.

Do you find a "credHelpers": key in your ~/.docker/config.json ? What is your operating system?

[djivko]

My OS is macOS Monterey.
Indeed I have a "credsHelpers" pointing to gcloud
"credHelpers":{"asia.gcr.io":"gcloud","eu.gcr.io":"gcloud","gcr.io":"gcloud","marketplace.gcr.io":"gcloud","staging-k8s.gcr.io":"gcloud","us.gcr.io":"gcloud"},

I am not sure though whether it was added after I installed gcloud CLI.

I would be interested if it works if you remove those "credHelpers" (for gcloud).

[djivko]

Confirmed that this was the issue.

I uninstalled gcloud cli, then removed "credHelpers" from config and gefyra up was successful.
Then I added back the "credHelper" and got the same error.

As usual it was issue with client env. Thanks for being so responsive and helpful.
