Thanks @manohar-koukuntla for the PR.

We have something very similar (also forked from Mimir's public jsonnet lib) internally that we were using it for our zone aware ingesters setup(with some minor tweaks.)

@cstyan knows more about it. @cstyan can we help @manohar-koukuntla tweak the PR a little and merge it?

@kavirajk Thank you. I am using the same concept we are using in mimir. Since mimir does extra tweaks on top of standard cortex zone awareness, I am using default cortex setting for loki and tempo(grafana/tempo#1936).

LGTM for the most part, just a few comments on things that I know caused issues for us internally, and I also left one question.

We have some more jsonnet, mostly related to ease of use + migrating to zone aware ingesters that I can port/update after your PR.

+    container.withArgs($.util.mapToFlags(
+      $.ingester_args + zone_args
+    )) +
+    container.withEnvMixin([{ name: 'AVAILABILITY_ZONE', value: zone_name }]),


is this from mimir or did you add it yourself? if the latter, do you mind leaving a comment as to what the intended use is for the env var?

I am using the same concept we are using in mimir. Since mimir does extra tweaks on top of standard cortex zone awareness, I am using default cortex setting for loki and tempo(grafana/tempo#1936).

Sorry if I was unclear, I am asking about the environment variable itself. I don't see a reason why we're adding it.
