Same container but different behaviour on different host

Zeppelinux,
I actually posted this in another place and got a good response/makes sense.

Docker starting numerous Java processes on host OS and as root

Yes you’re misunderstanding what a container is. It’s not like a virtual machine. The host can see all processes while from the containers pov only the processes within it’s namespace are visible. Same goes for networking, file system etc. Think of them more like chroots on steroids. So tomcat isn’t running on the hosts jvm, it’s running on whatever jvm that came bundled in the docker image and is self contained. John
