No Package Manager?

[shadowrylander]

     Hello!
     Sorry if this has already been answered somewhere, but for the life of me, I can't seem to find it.
     Whenever I try to call yum, in order to install, for example, docker, it returns a yum: command not found. How would I go about installing it, if possible? I installed anyfed itself using the prescribed:

apt update && apt install tar wget -y && export PATH=$PATH && wget https://raw.githubusercontent.com/nmilosev/anyfed/master/anyfed && bash anyfed

Then unset LD_PRELOAD, as I am rooted.
     Thank you kindly for your help on the matter!

dnf is Fedora package manager since Fedora 21. :)

Again, same problem: dnf: command not found. No idea why.
