# User can run the script as 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/shipyard.sh get actions
#

# 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.

# Commands requiring files as input utilize the pwd mounted into the container
# as the /target directory, e.g.:
#
# $ ./tools/shipyard.sh create configdocs design --filename=/target/afile.yaml

# Get the path of the directory where the script is located
# Source Base Docker Command

# this doesn't actually get exported to environment
# unless the script is sourced
