fix(loki): update config for Loki 3.x compatibility#448
Merged
Conversation
Loki config was written for 2.x and fails on 3.6.7 with: - max_transfer_retries: removed in 3.0 - enforce_metric_name: removed in 3.0 - max_look_back_period: removed in 3.0 Updated to Loki 3.x config: tsdb store, v13 schema, common block, compactor for retention. Volume path changed from /opt/loki to /loki (3.x runs as non-root UID 10001).
