# centos-release-openstack-newton package resides in the extras repo.
# All subsequent actual packages come from the CentOS Cloud SIG repo:
# http://mirror.centos.org/centos/7/cloud/x86_64/

# epel-release is needed to install supervisor.
# Traditionally a docker container runs a single process when it is launched.
# When you want to run more than one process in a container, you can use an
# external process management tool such as the supervisor (supervisord.org)

# Install PACO servers and S3 middleware.
# Install supervisor
# Install gluster-swift dependencies. To be removed when RPMs become available.
# Clean downloaded packages and index
