"""
Defines a healthcheck configuration for a container or service.
Args:
test (:py:class:`list` or str): Test to perform to determine
container health. Possible values:
- Empty list: Inherit healthcheck from parent image
- ``["NONE"]``: Disable healthcheck
- ``["CMD", args...]``: exec arguments directly.
- ``["CMD-SHELL", command]``: Run command in the system's
default shell.
If a string is provided, it will be used as a ``CMD-SHELL``
command.
interval (int): The time to wait between checks in nanoseconds. It
should be 0 or at least 1000000 (1 ms).
timeout (int): The time to wait before considering the check to
have hung. It should be 0 or at least 1000000 (1 ms).
retries (int): The number of consecutive failures needed to
consider a container as unhealthy.
start_period (int): Start period for the container to
initialize before starting health-retries countdown in
nanoseconds. It should be 0 or at least 1000000 (1 ms).
