Options

This is not a comprehensive list of options, but rather a list of features that I think are worth highlighting.

Authentication Environment Variables

gcp-nuke supports the following environment variables for authentication:

Variable Description
GOOGLE_APPLICATION_CREDENTIALS Path to a service account JSON key file
GOOGLE_APPLICATION_CREDENTIALS_JSON Service account JSON key as a string (takes precedence)

The GOOGLE_APPLICATION_CREDENTIALS_JSON variable is useful for CI/CD pipelines and containerized environments where you want to pass credentials directly without creating a file on disk.

Example: 

export GOOGLE_APPLICATION_CREDENTIALS_JSON='{"type":"service_account","project_id":"...","private_key":"..."}'
gcp-nuke run --config config.yaml --project-id playground-12345

Wait on Dependencies

--wait-on-dependencies will wait for dependent resources to be deleted before deleting resources that depend on them. This is useful when resources have dependencies on each other (e.g., a VPC network cannot be deleted until all subnets are deleted first).

Skip Prompts

--no-prompt will skip the prompt to verify you want to run the command. This is useful if you are running in a CI/CD environment. --prompt-delay will set the delay before the command runs. This is useful if you want to give yourself time to cancel the command.

Logging

  • --log-level will set the log level. This is useful if you want to see more or less information in the logs.
  • --log-caller will log the caller (aka line number and file). This is useful if you are debugging.
  • --log-disable-color will disable log coloring. This is useful if you are running in an environment that does not support color.
  • --log-full-timestamp will force log output to always show full timestamp. This is useful if you want to see the full timestamp in the logs.
