[Bug]: pulling private gcr.io (Google Cloud Artifacts Registry) Docker image fails

[djaax]

Error Message and Logs

I'm unable to deploy a docker image from a private Google Cloud Artifacts Registry.

Through the Coolify UI, I opened a Terminal session on localhost and installed all the gcloud stuff successfully. Here, I can simply pull my docker image, e.g. docker pull gcr.io/my-project/app:latest, no problem.

However, when I create a new Resource, select Docker Image and set the Docker Image to the same gcr.io/my-project/app:latest and click Deploy on the Configuration page, I get the following error in my Deployment Logs:

error getting credentials - err: exec: "docker-credential-gcloud": executable file not found in $PATH, out:''

In the localhost terminal, which docker-credential-gcloud returns a valid path that is in my $PATH.

It appears that my setup through the localhost terminal is not applied to wherever the docker pull is executed.

Steps to Reproduce

Prerequisites: Clean Coolify instance, a private Docker container in the Google Artifacts Registry, and a GCP service account with Artiacts Registry Admin permissions (as key.json).

1. Install gcloud through Coolify Terminal
2. Authenticate this Service Account on your Coolify machine through the Coolify Terminal: Save key.json locally and authenticate with gcloud auth activate-service-account --key-file key.json
3. Configure Docker using gcloud auth configure-docker gcr.io
4. Test this first: In the Terminal, pull image manually docker pull gcr.io/my-project/app:latest – this should succeed
5. In Coolify, create a new Resource > select Docker Image > set Docker Image to your repo gcr.io/my-project/app:latest – this fails
