# User can run the script like how they would execute the Shipyard CLI.
# For instance, to run the 'shipyard get actions' command, user can execute
# the following command after setting up the required environment variables:
#
# $ ./tools/run_shipyard.sh get actions
#

# NOTE: User can retrieve the IP of the ingress_controller_ip by executing
# the following command:
#
# ingress_controller_ip=`sudo kubectl get pods -n ucp -o wide | grep -v ingress-error-pages | grep -m 1 ingress | awk '{print $6}'`
#

# NOTE: User should update /etc/hosts with the IP of the ingress
# controller if DNS resolution of the Keystone and Shipyard URLs
# is not available. User can execute the following command to update
# the /etc/hosts file:
#
# cat << EOF | sudo tee -a /etc/hosts
#
# $ingress_controller_ip keystone.ucp
# $ingress_controller_ip shipyard-api.ucp.svc.cluster.local
# EOF
#

# NOTE: User will need to set up the necessary environment variables
# before executing this script. For instance, user can set up the
# environment with the following default values:
#
# export SHIPYARD_IMAGE='quay.io/attcomdev/shipyard:latest'
# export OS_AUTH_URL="http://keystone.ucp:80/v3"
# export OS_IDENTITY_API_VERSION=3
# export OS_USERNAME="shipyard"
# export OS_USER_DOMAIN_NAME="default"
# export OS_PASSWORD="password"
# export OS_PROJECT_DOMAIN_NAME="default"
# export OS_PROJECT_NAME="service"
#
# Define OpenStack Environment Variables

OS_IDENTITY_API_VERSION=`env | grep OS_IDENTITY_API_VERSION`
OS_USERNAME=`env | grep OS_USERNAME`
OS_USER_DOMAIN_NAME=`env | grep OS_USER_DOMAIN_NAME`
OS_PASSWORD=`env | grep OS_PASSWORD`
OS_PROJECT_DOMAIN_NAME=`env | grep OS_PROJECT_DOMAIN_NAME`
OS_PROJECT_NAME=`env | grep OS_PROJECT_NAME`

# Define shipyard image variable
# NOTE: We only want the location of the image. Hence we will need
# to stip off 'SHIPYARD_IMAGE=' from SHIPYARD_IMAGE_ENV_VARIABLE
SHIPYARD_IMAGE_ENV_VARIABLE=`env | grep SHIPYARD_IMAGE`
SHIPYARD_IMAGE="${SHIPYARD_IMAGE_ENV_VARIABLE#*=}"

# Define Base Docker Command
# NOTE: We will mount the current directory so that any directories
# would be relative to that
# NOTE: We will map the host directory to '/home/shipyard/host' on
# the Shipyard docker container
