Description Kevin Fenzi 2018-07-23 03:35:40 UTC
Hope this is the right place for this, if not please move to podman or selinux-policy or whatever. 

In enforcing mode a rawhide install isn't able to run bash in a container: 

~ sudo podman run --rm=true -it --user root --dns=10.88.0.1 registry.fedoraproject.org/fedora:rawhide
~ 

avcs:

Happy to gather more info or test fixes.

Could you make sure container-selinux installed correctly?

yum reinstall container-selinux

Comment 2 Kevin Fenzi 2018-07-23 16:28:07 UTC
Oops, sorry. I forgot to mention that this is on a ostree boot. So I cannot re-install here (and due to bug 1607223, rpm-ostree overlay doesn't work). 

I do see verify shows a few things, but only timestamps: 

# rpm -V container-selinux
.......T.  d /usr/share/doc/container-selinux/README.md
.......T.    /usr/share/selinux/devel/include/services/container.if                                                   
.......T.    /usr/share/selinux/packages/container.pp.bz2

I can boot a normal install and see how it does there in a bit here.

Comment 3 Kevin Fenzi 2018-07-23 20:07:01 UTC
ok, in a normal boot it works. 

So, it's something particular to the ostree install it seems.
