## installation of OpenStack via OPNFV Compass4nfv, on Ubuntu, virtual deployment
#################################################################################
# reference manual: https://docs.opnfv.org/en/latest/submodules/compass4nfv/docs/release/installation/index.html
# page for virtual deployment: https://docs.opnfv.org/en/latest/submodules/compass4nfv/docs/release/installation/vmdeploy.html

echo "*** begin AUTO install: OPNFV Compass4nfv"

# prepare install directory
export INSTALLDIR=/opt/opnfv-compass
mkdir -p $INSTALLDIR
cd $INSTALLDIR

# premptively install latest pip and clear $PATH cache
# with apt-get (see apt-get -h and man apt-get for details)
apt-get -y update
apt-get -y upgrade
apt-get -y install python-pip
pip install --upgrade pip
hash -r
apt-get -y install python3-openstackclient
apt-get -y autoremove

## note: apt is more recent than apt-get (apt was formally introduced with Ubuntu 16.04)
## APT: Advanced Packaging Tool; apt is more high-level, apt-get has more features;
# apt -y update # Refreshes repository index
# apt -y full-upgrade # Upgrades packages with auto-handling of dependencies
# apt -y install python-pip
# pip install --upgrade pip
# hash -r
# apt -y install python3-openstackclient
# apt -y autoremove


# 2 options: (option 1 is preferable)
# 1) remain in master branch, use build.sh (which builds a tar ball), then launch deploy.sh
# 2) download a tar ball and launch deploy.sh in a branch matching the tar ball release (e.g. fraser 6.2)


##############
# OPTION 1: build.sh + deploy.sh in master branch

# retrieve the repository of Compass4nfv code (this creates a compass4nfv subdir in the installation directory), current master branch

# edit in deploy.sh specific to OPTION 1
# set path to ISO file (tar ball), as built by build.sh previously
# absolute path to tar ball file URL (MUST be absolute path)

##############

# OPTION 2: tar ball + deploy.sh in matching releases/branches

# download tarball of a certain release/version
#echo "*** begin download Compass4nfv tar ball"
#wget http://artifacts.opnfv.org/compass4nfv/fraser/opnfv-6.2.tar.gz
