# We will need to pass the name of the site/collection as well as the
# path of the directory where the YAMLs are stored when we execute the
# script. It is mandatory to do so and the script will exit with exception
# if these parameters are missing. For instance, we can execute the script
# in the following manner:
#
# $ ./deckhand_load_yaml.sh site1 '/home/ubuntu/site1'
#
if [[ -z "$1" ]]; then
    echo -e "Please specify site/collection name!"
    exit 1

if [[ -z "$2" ]]; then
    echo -e "Please specify the directory where the YAMLs are stored!"
    exit 1
fi

# NOTE: If user is executing the script from outside the cluster, e.g. from
# a remote jump server, then he/she will need to ensure that the DNS server
# is able to resolve the FQDN of the Shipyard and Keystone public URL (both
# will be pointing to the IP of the Ingress Controller). If the DNS resolution
# is not available, the user will need to ensure that the /etc/hosts file is
# properly updated before running the script.

# collection, e.g. "site1" into Deckhand (as a bucket in a revision)
# Note that the name of the collection differs from site to site and is

# Note that we will also make use of the '--replace' option so that the
