第 18 章 Preparing and uploading custom GCE images to Google Cloud

Procedure

1. Use a text editor to create a gcp-config.toml configuration file with the following content:

   provider = "gcp"
   [settings]
   bucket = "<gcp_bucket>"
   region = "<gcp_storage_region>"
   object = "<object_key>"
   credentials = "<gcp_credentials>"

   • <gcp_bucket> points to an existing bucket. It is used to store the intermediate storage object of the image which is being uploaded.
   • <gcp_storage_region> is both a regular Google storage region and a dual or multi-region.
   • <object_key> is the name of an intermediate storage object. It must not exist before the upload, and it is deleted when the upload process is done. If the object name does not end with .tar.gz, the extension is automatically added to the object name.

   • <gcp_credentials> is a Base64-encoded scheme of the credentials JSON file downloaded from Google Cloud. The credentials determine which project the Google Cloud uploads the image to.

     注意

     Specifying <gcp_credentials> in the gcp-config.toml file is optional if you use a different mechanism to authenticate with Google Cloud. For other authentication methods, see Authenticating with Google Cloud.

2. Retrieve the <gcp_credentials> from the JSON file downloaded from Google Cloud.

   $ sudo base64 -w 0 cee-gcp-nasa-476a1fa485b7.json

3. Create a compose with an additional image name and cloud provider profile:

   $ sudo image-builder build gce --blueprint <blueprint_name> <image_key> gcp-config.toml

   The image build, upload, and cloud registration processes can take up to ten minutes to complete.
