Set nginx.ingress.kubernetes.io/service-upstream true by default
Per discussions, the default in charts will set:
nginx.ingress.kubernetes.io/service-upstream: "true"
and administrators will have the option to override it if needed for their deployment installation.
This is a break out from !1633 (comment 441190442)
Mitchell Nielsen @mnielsen We can specify this here, but it might be worth providing as a default annotation in our standard chart that can be overridden if needed.
Robert Marshall @rmarshall I agree that we should break this out to a standard annotation in our charts.
@WarheadsSE or @twk3 - do you see any objections to that from your perspective as a maintainer?
DJ Mountney @twk3 Let's move it into chart default, but still make it configurable, so users can turn off the annotation if it happens to conflict with their existing config
