in our org we use 3 AZ for mimir and we would like to be able do that with Tempo
Describe the solution you'd like
Ability to specify an AZ in cli flag like -ingester.availability-zone

use ENV var (but as we use helm chart its not possible)
Additional context

@zalegrala @joe-elliott, i've seen we parse the Cli flags here
and we use default flags in ring.lifecyclerConfig which already has this cli flag defined here
does this mean i just need to export this flag in Tempo cli ? or is there anything else needed ?

[joe-elliott]

That is correct. If you'd like to expose that config option you simply need to add a line in RegisterFlagsAndApplyDefaults
