About Repos

The Stacki frontend acts as the yum/zypper/ubuntu repository for all packages you might want on a system.

For instance, the /etc/yum.repos.d/stacki.repo for a set of boxes/pallets on this stacki frontend:

# stack list pallet
NAME              VERSION              RELEASE ARCH   OS     BOXES
os                7.4_20171128         redhat7 x86_64 redhat

epel              20180104             redhat7 x86_64 redhat default kaiser

looks like this:

The stacki.repo file gets replicated to the backends and is the repository for any RPMS you may wish to have. Adding additional repositories (like epel or extras) should be done by following the Adding Software Pallets guide. This allows easy versioning, updates, etc, without having to have every machine open to the world.

You'll note, that carts are also part of this repository, so packages can be aded in carts and be part of the repository of all the things.

To sync a repository to backends, if you add a new cart for example, then:

stack sync host repo a:backend

and the packages you've added will now be available via yum/zypper/apt-get.
