Rockstor and Minecraft Server

General
23

I’m getting out of my depth here, but maybe you can extract the health check information from the instance by running:

docker inspect a00ed924ec84
and look for (in your case, probably “unhealthy”):

{
  "Status": "healthy",
  "FailingStreak": 0,
  "Log": [

…

or, if you have jq installed,

docker inspect 497a3195b26c | jq '.[].State.Health'

When looking over the overall output (not using jq) it seems that the healthcheck involves checking whether the port works …

            "Healthcheck": {
            "Test": [
                "CMD-SHELL",
                "/usr/local/bin/mc-monitor status-bedrock --host localhost --port $SERVER_PORT"
            ],
            "StartPeriod": 60000000000

But, like I said, I’m reaching the end of my knowledge here :frowning:

That’s an interesting one. I tried your rock-on file as well and can confirm it works for me like it does for @Hooverdan. By the way, thanks @Hooverdan for the Healthcheck bit, I’ve learned something rather important thanks to you!

@ror, would you mind posting the entire docker inspect output? The error posted above might point towards some IPV6 difficulties, maybe… Sorry if I have missed it, but what Rockstor version are you using (as given by yum info rockstor)?

OK I’ll start with entire docker inspect output:
