Getting this error while pushing my docker image to container registry

[Vinayak1]

unauthorized: You don't have the needed permissions to perform this operation, and you may have invalid credentials. To authenticate your request, follow the steps in: https://cloud.google.com/container-registry/docs/advanced-authentication

The link you provided for advanced authentication methods is deprecated. Here are some updated resources to help you authenticate with Google Container Registry:

1. Set up authentication for Docker:

This page provides instructions on configuring Docker to authenticate with Artifact Registry Docker repositories, which includes GCR. It covers both basic and advanced methods: https://cloud.google.com/artifact-registry/docs/docker/authentication

2. gcloud auth configure-docker:

This command allows you to configure Docker to use gcloud credentials for authentication with GCR. It's a simpler option compared to the Credential Helper: https://cloud.google.com/sdk/gcloud/reference/auth/configure-docker

3. Application Default Credentials (ADC):

If you're running on a Google Cloud environment like Cloud Build or Kubernetes Engine, ADC automatically authenticates you with GCR. You don't need additional configuration: https://cloud.google.com/sdk/gcloud/reference/auth/application-default/login

4. Troubleshooting:

If you're still encountering issues, check the following:

• Ensure your account has the required IAM roles for pushing images to the specific registry.
• Verify you're authenticated with the correct GCP account using gcloud auth login.
• Check the expiration of your credentials and refresh them if needed.
• Confirm you're using the correct project ID.
• Review the Docker push logs for specific error messages.
