# basically this is needed because the oncall backend containers have been configured to communicate w/ grafana via
# http://localhost:3000 (GRAFANA_API_URL). This URL is used in two scenarios:
# 1. oncall backend -> grafana API communication (happens within docker)
# 2. accessing templated URLs generated by the oncall backend - meant to be accessed via a browser on your host machine
# The alternative is to set GRAFANA_API_URL to http://grafana:3000. However, this would only work in scenario #1
# as http://grafana:3000 would not be resolvable on the host machine (without modifying /etc/hosts)
#
# by adding this extra_host entry to the oncall backend containers any calls to localhost will get routed to the docker
# gateway, onto the host machine, where localhost:3000 points to grafana
