Action: healthAction,
Usage: "get the status of the CA",
UsageText: `**step ca health**
[**--ca-url**=<URI>] [**--root**=<file>]`,
Description: `**step ca health** makes an API request to the /health
endpoint of the Step CA to check if it is running. If the CA is healthy, the
response will be 'ok'.
## EXAMPLES
Using the required flags:
'''
$ step ca health --ca-url https://ca.smallstep.com:8080 --root path/to/root_ca.crt
ok
'''
With the required flags preconfigured:
**--ca-url** is set using environment variables (as STEP_CA_URL) or the default
configuration file in <$STEPPATH/config/defaults.json>.
**--root** is set using environment variables (as STEP_ROOT), the default
configuration file in <$STEPPATH/config/defaults.json> or the default root
certificate located in <$STEPPATH/certs/root_ca.crt>
'''
$ step ca health
ok
'''`,
