Google Cloud Platform - Unable to push Docker Image

Welcome to the first post in 2020!

I hope you had a good start and you are ready for some new content on the blog.

In this blog post I will show you what to do in case you can’t push Docker image to Google Cloud Platform Container Registry.

As I am progressing through Acloud Guru Course Google Kubernetes Engine (GKE): Beginner to Pro I found some strange issue.

At the beginning of the course I’ve created a Google Cloud Container Registry by executing following command docker tag myapp gcr.io/cka-fwc/myapp followed by docker push myapp gcr.io/cka-fwc/myapp. It worked like a charm.

After that I deleted my project and I created new one with the same name of the project. ID of course was different but wasn’t that important back then.

Issue

I fired up GCP console and I tried to push docker image to container registry.

I had errors such as:

docker push myapp gcr.io/cka-fwc/myapp
The push refers to repository [gcr.io/cka-fwc/myapp]

Solution

I couldn’t figure out what the issue might be. After a while I’ve tried the following commands:

docker tag myapp gcr.io/cka-fwc-267314/myapp

docker push myapp gcr.io/cka-fwc-267314/myapp

It worked like a charm!

The push refers to repository [gcr.io/cka-fwc-267314/myapp]

So instead of using GCP project name I used it’s ID and it worked. I hope you will find this useful.
