# Build and run this container with:
# 
# docker build --rm -t $USER/atomicrepo .
# docker run -d -p 8000:8000 --name atomicrepo $USER/atomicrepo
# docker exec -it atomicrepo bash 
# 
# Inside the container, mod tree file as described in Step Three of 
# https://github.com/jasonbrooks/byo-atomic/blob/master/README.md
# 
# Then, compose tree with:
#
# rpm-ostree compose tree  --proxy=http://127.0.0.1:8123  --repo=/srv/repo fedora-atomic/fedora-atomic-docker-host.json
#
# Or, for CentOS, with:
#
# rpm-ostree compose tree  --proxy=http://127.0.0.1:8123  --repo=/srv/repo sig-atomic-buildscripts/centos-atomic-host.json
# 
# When the compose is complete, your tree will be accessible at 
# http://$YOUR_IP:8000/repo
# 
# To configure an Atomic host to receive updates from your build machine, 
# run a pair of commands like the following to add a new "foo" repo definition 
# to your host, and then rebase to that tree:
#
# sudo ostree remote add foo http://$YOUR_IP:8000/repo --no-gpg-verify
#
# sudo rpm-ostree rebase foo:fedora-atomic/f23/x86_64/docker-host
