I think it should have that flag. If you run a container what does cat
/proc/self/attr/current show?

------------------------

# docker run hello-world

.........

# cat /proc/self/attr/current
unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023#  

----------------------------

Should have been more clear

docker run fedora cat /proc/self/attr/current

What does this command show?

Of course I would prefer

podman run fedora cat /proc/self/attr/current

I didn't know this command...so many new stuff to learn !

------------------

 % man podman
No manual entry for podman

--------------------

:-(   snif

Thats weird. 

rpm -q podman
podman-0.5.4-1.git1f2e2a2.fc28.x86_64

Their should be man pages. You doing this on atomic host?

YES.

Atomic host excludes man pages.
You can read lots of docs on podman at
https://github.com/projectatomic/libpod/

Man pages are here
https://github.com/projectatomic/libpod/blob/master/commands.md

You never showed me the output of the docker command.

docker run fedora cat /proc/self/attr/current

BTW Podman is new container runtime for running pods and containers, modeled after the Docker CLI, but does not use a container daemon to do it's thing.
