# Operations - Local Deployment
# ------------------------------------------------------------------------------

# NOTE:
# The environment used for "make debug" or "make run" by default should
# have a Kong Gateway deployed into the kong-system namespace, but these
# defaults can be changed using the arguments below.
#
# One easy way to create a testing/debugging environment that works with
# these defaults is to use the Kong Kubernetes Testing Framework (KTF):
#
# $ ktf envs create --addon metallb --addon kong --kong-disable-controller --kong-admin-service-loadbalancer
#
# KTF can be installed by following the instructions at:
# https://github.com/kong/kubernetes-testing-framework
#
# Alternatively one can use Kong's helm chart to deploy it on the cluster, using
# for example the following set of flags:
#   helm upgrade --create-namespace --install --namespace kong-system kong kong/kong \
#       --set ingressController.enabled=false \
#       --set admin.enabled=true \
#       --set admin.type=LoadBalancer \
#       --set admin.http.enabled=true \
#       --set admin.tls.enabled=false
