How to use

Testing http probes

Use URL parameters to customize the response to requests sent on any path of this server.

• delaySeconds: The number of seconds to wait before returning, defaults to 0.

• status: The HTTP status code to return, default to 200.

• failures: The number of failures (500 responses) to return before returning the status above, default to 0.

• /healthcheck?delaySeconds=10&status=500: will return a 500 status code with a delay of 10 seconds

• /?failures=5: will return a 5 500 responses followed by 1 200 response

Testing TCP probes

Use environment variables to customize the time before the server listens on the port.

• SERVER_DELAY_SECONDS (defaults to 0): The number of seconds to wait before listening on the port.
• SERVER_PORT (defaults to PORT, or to 8080 if not present): The port to listen on.
