Pay attention to container safety! Run a Python process as a normal user

Take rabbitmq as an example, let's see what user he uses to run! Is it root or an ordinary user, or an ordinary privileged user!

 root@taskgen_rabbitmq_host:/proc/1# ps -eo pid,user,group,euser,egroup,cmd
  PID USER     GROUP    EUSER    EGROUP   CMD
    1 rabbitmq rabbitmq rabbitmq rabbitmq /bin/sh /opt/rabbitmq/sbin/rabbitmq-server
   21 rabbitmq rabbitmq rabbitmq rabbitmq /usr/local/lib/erlang/erts-12.2/bin/beam.smp -W w -MBas ageffcbf -MHas ageffcbf -MBlmbcs 512 -MHlmbcs 512 -MMmcs 30 -P 1048576 -t 5000000 -stbt db -zdbbl 128000 -sbwt none -sbwtdcpu none -sbwtdio none -B i -- -root /usr/local/lib/erlang -progname erl -- -home /var/lib/rabb

 7458 root     root     root     root     ps -eo pid,user,group,euser,egroup,cmd

We can see that user is rabbitmq , is this rabbitmq privileged?

 root@taskgen_rabbitmq_host:/proc/1# awk -F: '$3==0 {print $1}' /etc/passwd
root

As you can see, there is only one privileged user, namely root , rabbitmq without privileges
