How to set readiness and liveness port ?

[lnthai2002]

Hello,
I am using operator 1.2.1 and recently we have an issue that the broker took a while to startup thus kubernetes killed it. I saw failed readiness event when i describe the artemis broker pod. I am looking for answer to the following questions:

1. I added readiness and liveness config but I don't know which value to set tcpSocket.
2. Which endpoint (URL) can I use to check broker readiness?

Another strange behavior I observed is that if the broker is running correctly with the default config then I change the readiness config to a bad port (for example using the port that used for address binding) then I should get the failed readiness event immediately; however, I didn't get failed readiness for such case.

You can find examples for readiness and liveness probes in the doc, see https://github.com/artemiscloud/activemq-artemis-operator/blob/main/docs/help/operator.md#liveness-readiness-and-startup-probes

Another strange behavior I observed is that if the broker is running correctly with the default config then I change the readiness config to a bad port (for example using the port that used for address binding) then I should get the failed readiness event immediately; however, I didn't get failed readiness for such case.

Can you share your CR?

Thanks,
I saw the example but I don't understand why it used port 8181. There is nothing listen on port 8181, i dont see any kubernetes service open for that port.
Also, the example do not show how to check for readiness/liveness using http request to the broker, is there an endpoint similar to springboot actuator /actuator/health that i can use to check if the broker is ready/live?

Here is my CR:

@lnthai2002 sorry for the late reply, I missed the notification. I confirm that broker port 8181 is a typo the correct value is 8161 that is the port of the embedded web server. I have just fixed it artemiscloud@f407dbc
