通过JMX监控在Docker中运行的Spring Boot App

Question

I am using docker swarm & Traefic to manage and deploy my containers. Unfortunately, I didn't set it up and not sure details, all I do is just deploy my app there and everything taken care of. I am running Spring Boot Apps, each app could have multiple instances. Docker file is pretty simple, basically

ENTRYPOINT java -jar /app.jar

And we use Traefic to manage it as well.

I am trying to connect jconsole to different apps but not sure how to do it for remote app that runs in docker swarm remotely. Locally no issues.

I read on an internet about setting JMX setting when starting java app but all information about connecting to app running in docker locally or with static IP. I imagine I do not have static IP to add to my configuration, it always assigned dynamicly.

Any advise or where to start look would be gladly appreciated

To map multiple containers, you can use the container hostname. When you run a container like "docker run -ti ... --hostname test1 ..." or run a service "docker service create ... name= test1...".

So, you have to hitting via hostname.
