procedure

1. gcloud settings

1. Install the gcloud command in your local environment
   • https://cloud.google.com/sdk/docs/quickstart-macos?hl=ja
2. Initial setting
   • gcloud init

2. Create a service account for Push / Pull of the image

When using your own user account, if the projects are linked in various ways, you are afraid of making a mistake in selecting the project ID, so create a dedicated service account.

1. Create a service account --Working on the console
2. Authority settings --The container image of "Container Registry" is managed by Cloud Storage, and the authority is just to grant the "Storage administrator" authority of Cloud Storage.
   • https://cloud.google.com/container-registry/docs/access-control#grant https://cloud.google.com/sdk/docs/authorizing?hl=ja#authorizing_with_a_service_account
3. Create a key for the service account and set up authentication locally
   • gcloud auth activate-service-account
   • https://cloud.google.com/sdk/docs/authorizing?hl=ja#authorizing_with_a_service_account

3. Docker authentication settings

Settings for using gcloud as a Docker authentication helper

1. Run gcloud auth configure-docker locally

4. Push Docker image

• If you have multiple accounts, switch accounts below. gcloud config set account [ACCOUNT]

1. Tag the local image with the registry name --Naming convention: [HOSTNAME] / [PROJECT-ID] / [IMAGE] -[HOSTNAME]: Select from the following. This will determine where to save the image. --gcr.io hosts the image in a data center in the United States, but its location is subject to change in the future. --us.gcr.io is a storage bucket that hosts the image in a data center in the United States, but is independent of the image hosted by gcr.io. --eu.gcr.io hosts the image in the European Union. --asia.gcr.io hosts the image in a data center in Asia. -[PROJECT-ID]: Project ID of the target Google Cloud project -[IMAGE]: Name of container image --Tagging command: docker tag [local image name or image ID] [registry name]: [tag (latest if not specified)]
2. Push --docker push [registry name]: [tag (latest if not specified)]

If you push a new one, a repository will be created on the Container Registry.
