The healthz endpoint is deprecated (since Kubernetes v1.16), and you should use the more specific livez and readyz endpoints instead. The livez endpoint can be used with the --livez-grace-period flag to specify the startup duration. For a graceful shutdown you can specify the --shutdown-delay-duration flag with the /readyz endpoint. Machines that check the healthz/livez/readyz of the API server should rely on the HTTP status code. A status code 200 indicates the API server is healthy/live/ready, depending on the called endpoint.\n\nThese endpoints align with how Kubernetes HTTP probes function\n\nlivez: Use this to determine if the API server should be restarted. If /livez returns a failure status code (such as 500), the API server is likely in a non-recoverable state, such as a deadlock, and requires a restart. readyz: Use this to determine if the API server is ready to accept traffic. If /readyz returns a failure status code, it indicates the server is still initializing or temporarily unable to serve requests (for example, waiting for etcd to be available), and traffic should be routed away from it.\n\nThe more verbose options shown below are intended to be used by human operators to debug their cluster or understand the state of the API server.\n\nThe following examples will show how you can interact with the health API endpoints.\n\nFor all endpoints, you can use the verbose parameter to print out the checks and their status. This can be useful for a human operator to debug the current status of the API server, it is not intended to be consumed by a machine\n\nBounded code example (external data; do not execute automatically):\n```shell\ncurl -k https://localhost:6443/livez?verbose\n```\n\nor from a remote host with authentication\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get --raw='/readyz?verbose'\n```\n\nThe output will look like this\n\nThe Kubernetes API server also supports to exclude specific checks. The query parameters can also be combined like in this example\n\nBounded code example (external data; do not execute automatically):\n```shell\ncurl -k 'https://localhost:6443/readyz?verbose&exclude=etcd'\n```\n\nThe output show that the etcd check is excluded\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
