Getting err="too many failed ingesters" when running on docker

[dorroddorrod]

When running loki on separate components mode ( ingester,querier,distibuter,table-manager)
Getting the following error :
loki-querier | level=error ts=2020-06-01T09:22:37.9300754Z caller=pool.go:161 msg="error removing stale clients" err="too many failed ingesters" loki-distributor | level=error ts=2020-06-01T09:22:38.2747819Z caller=pool.go:161 msg="error removing stale clients" err="too many failed ingesters"

Hey, let's see if I can help. The current bottleneck is due to the combination of the replication_factor: 3 config and running one replica of the ingester. It's basically saying "all data must be replicated 3 times", but only presents it one ingester to replicate the data to. You'll need to either scale back the replication factor or scale out the ingesters.

Thanks, it works !
