engine start

The Kurtosis engine starts automatically when you run any command that interacts with the engine, such as kurtosis enclave add, but there may be times where the engine has been stopped and you may need to start it again (e.g. starting the engine on a specific version). To do so, run:

kurtosis engine start

This command will do nothing if the Kurtosis engine is already running.

You may optionally pass in the following flags with this command:

  • --log-level: The level that the started engine should log at. Options include: panic, fatal, error, warning, info, debug, or trace. The engine logs at the info level by default.
  • --version: The version (Docker tag) of the Kurtosis engine that should be started. If not set, the engine will start up with the default version.
  • --enclave-pool-size: The size of the Kurtosis engine enclave pool. The enclave pool is a component of the Kurtosis engine that allows us to create and maintain 'n' number of idle enclaves for future use. This functionality allows to improve the performance for each new creation enclave request.
  • --github-auth-token: The auth token to use for authorizing GitHub operations. If set, this will override the currently logged in GitHub user from kurtosis github login, if one exists. Note, this token does not persist when restarting the engine.

CAUTION: The --enclave-pool-size flag is only available for Kubernetes.
