如果更改项目名称，Google Container Registry 会面临哪些风险？

Question

I have a CI/CD pipeline configured where Google Cloud Build automatically builds containers from code pushed to a GitHub repo if tagged with a specific tag. The containers are automatically deposited into Google Container Registry. Each container in the registry is tagged with a tag in the form us.gcr.io/project_name/container_name:tag_name

My question is if I change the project name, how will this affect the containers currently sitting in Google Container Registry that I have already tagged with the current project name? Do I need to change the tag on each container with the intended project name before updating the project name itself? Is this handled automatically by GCP?

Answer 1

Registries in Container Registry are named by the host and project ID . To work with images (for example push, pull, delete) identify the image using the following format:

[HOSTNAME]/[PROJECT-ID]/[IMAGE]:[TAG]

Or [HOSTNAME]/[PROJECT-ID]/[IMAGE]@[IMAGE_DIGEST]

Even if you change your PROJECT NAME, PROJECT ID can't be changed, because Project ID: a unique identifier for your project, composed of the project name and a randomly assigned number . So your images keep with the same registries in Container Registry. us.gcr.io/project_id/container_name:tag_name
