LXC - Can't access package manager from linux container

Question

I have LXD installed on a fedora 27 machine. I configured it a while ago, and it has worked fine long enough that I forgot how I set everything up. I just tried to create a new container and it creates successfully, but I can't get it to access the package manager. I vaguely remember this being a problem when I created my other containers back when I installed everything, but I can't remember how I fixed it. As of now, my other old containers work fine, and have access to the package manager, and everything works fine. But when I create a new container, it acts as though the package manager doesn't exist.

How do I install the package manager to a new Linux Container using LXD?

Thanks,

Ok, I'm an idiot, the Fedora image defaults to using the DNF package manager. So, either use that, or use it to install yum:

[root@neon ~]# lxc launch images:fedora/27 myThing
Creating myThing
Starting myThing
[root@neon ~]# lxc exec myThing bash
[root@myThing ~]# dnf update

Nothing to do.
Complete!
[root@myThing ~]# dnf install yum
