docker find container by pid of inside process

Question

I have docker containers. Inside them launched a process. From the host machine the command top outputs pid of all processes launched in within containers.

How can I find a container in which the process with this PID is running?

Thank you.

Answer 1

Thank you @Alex Past and @Stanislav for the help. But I did not get full answers for me. I combined them.
In summary I has got next.

First

pstree -sg <PID>

where PID is the process's PID from the command top

In output I am getting parent PID for the systemd parent process. This PID is docker container's PID.

After I execute

docker ps -q | xargs docker inspect --format '{{.State.Pid}}, {{.Name}}' | grep "^%PID%"

where %PID% is this parent PID.

In result I have docker's CONTAINER ID.

That's what I wanted
