Pei Tong ba9fa99f6c blueprint cluster-installation
Add install tool

The tool aims to make the deploying of stackube as easy as possible.
User could set up a whole Stackube cluster automatically by using it.
It uses docker images provided by OpenStack Kolla Project to run a
containerized OpenStack, and uses kubeadm to deploy kubenetes, then
bootstrap the Stackube cluster.

# Distro Functions

# these variables directly! The "is_*" functions defined below this
# bundle up compatible platforms under larger umbrellas that we have
# determinted are compatible enough (e.g. is_ubuntu covers Ubuntu &
# Debian, is_fedora covers RPM-based distros). Higher-level functions
# such as "install_package" further abstract things in better ways.

# We can't make a good choice here. Setting a sensible DISTRO
# is part of the problem, but not the major issue -- we really

# The bigger problem is categorising the system into one of
# our two big categories as Ubuntu/Debian-ish or
# Fedora/CentOS-ish.
#
# The setting of os_PACKAGE above is only set to "deb" based
# on a hard-coded list of vendor names ... thus we will
# default to thinking unknown distros are RPM based
# (ie. is_ubuntu does not match). But the platform will then
# also not match in is_fedora, because that also has a list of
# names.
#
# So, if you are reading this, getting your distro supported
# is really about making sure it matches correctly in these
# functions. Then you can choose a sensible way to construct
# DISTRO based on your distros release approach.
