# DO NOT EDIT THE SCRIPT
# Instead, update the j2 template, and regenerate it for dev with `make render-docs`.

# TODO (@NickLarsenNZ): Use bitnami/postgres chart, and add version var to the above list
# See similar changes in: https://github.com/stackabletech/hive-operator/pull/489/commits/8189f196f018c009370ae9b07a3f9609ee2e8681

# This script contains all the code snippets from the guide, as well as some assert tests
# to test if the instructions in the guide work. The user *could* use it, but it is intended
# for testing only.
# The script will install the operators, create a superset instance and briefly open a port
# forward and connect to the superset instance to make sure it is up and running.
# No running processes are left behind (i.e. the port-forwarding is closed at the end)
