Google Cloud Container Registry Docker Push

Github action to push a docker image to Google Cloud's Container Registry.

Other registries are supported, if you override defaults.

Prerequisites

Set up the following resources manually in the Cloud Console or use a tool like Terraform.

• Enable Artifact Registry service and create a Docker image registry
• Create Service Account with permissions to read and write to the image registry

Before this action runs, you are responsible for building the image and tagging it with all the tags you need. Example tags may look like:

• gcr.io/my-project-name-123456/image-name
• gcr.io/my-project-name-123456/image-name:latest
• gcr.io/my-project-name-123456/image-name:1
• gcr.io/my-project-name-123456/image-name:1.0
• gcr.io/my-project-name-123456/image-name:1.0.1

All tags will be pushed.
