gcloud alpha compute project-info add-metadata - add or update project-wide metadata

gcloud alpha compute project-info add-metadata [--metadata=KEY=VALUE,[KEY=VALUE,…]] [--metadata-from-file=KEY=LOCAL_FILE_PATH,[…]] [GCLOUD_WIDE_FLAG …]

Only metadata keys that are provided are mutated. Existing metadata entries will remain unaffected.

If you are using this command to manage SSH keys for your project, please note the risks of manual SSH key management as well as the required format for SSH key metadata, available at https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys

--metadata=KEY=VALUE,[KEY=VALUE,…]

Metadata to be made available to the guest operating system running on the instances. Each metadata entry is a key/value pair separated by an equals sign. Each metadata key must be unique and have a max of 128 bytes in length. Each value must have a max of 256 KB in length. Multiple arguments can be passed to this flag, e.g., --metadata key-1=value-1,key-2=value-2,key-3=value-3. The combined total size for all metadata entries is 512 KB.

In images that have Compute Engine tools installed on them, such as the official images, the following metadata keys have special meanings:

startup-script

Specifies a script that will be executed by the instances once they start running. For convenience, --metadata-from-file can be used to pull the value from a file.

startup-script-url

Same as startup-script except that the script contents are pulled from a publicly-accessible location on the web. For startup scripts on Windows instances, the following metadata keys have special meanings: windows-startup-script-url, windows-startup-script-cmd, windows-startup-script-bat, windows-startup-script-ps1, sysprep-specialize-script-url, sysprep-specialize-script-cmd, sysprep-specialize-script-bat, and sysprep-specialize-script-ps1. For more information, see Running startup scripts. At least one of [--metadata] or [--metadata-from-file] is required.

--metadata-from-file=KEY=LOCAL_FILE_PATH,[…]

Same as --metadata except that the value for the entry will be read from a local file. This is useful for values that are too large such as startup-script contents. At least one of [--metadata] or [--metadata-from-file] is required.
