Ashwanth	a118e994d8	Remove shared_store and shared_store_key_prefix from shipper and compactor (#10840) ... **What this PR does / why we need it**: #### Removes `shared_store` and `shared_store_key_prefix` from index shipper and compactor configs and their corresponding CLI flags. - `-tsdb.shipper.shared-store` - `-boltdb.shipper.shared-store` - `-tsdb.shipper.shared-store.key-prefix` - `-boltdb.shipper.shared-store.key-prefix` - `-boltdb.shipper.compactor.shared-store` - `-boltdb.shipper.compactor.shared-store.key-prefix` `shared_store` has been a confusing option allowing users to easily misconfigure Loki. Going forward `object_store` setting in the [period_config](https://grafana.com/docs/loki/latest/configure/#period_config) (which already configured the store for chunks) will be used to configure store for the index. And the newly added `path_prefix` option under the `index` key in `period_config` will configure the path under which index tables are stored. This change enforces chunks and index files for a given period reside together in the same storage bucket. More details in the upgrade guide. --- `-compactor.delete-request-store` has to be **explicitly configured** going forward. Without setting this, loki wouldn't know which object store to use for storing delete requests. Path prefix for storing deletes is decided by `-compactor.delete-request-store.key-prefix` which defaults to `index/`. **Checklist** - [X] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [X] Documentation added - [X] Tests updated - [x] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [X] Changes that require user attention or interaction to upgrade are documented in `docs/sources/setup/upgrade/_index.md` - [ ] For Helm chart changes bump the Helm chart version in `production/helm/loki/Chart.yaml` and update `production/helm/loki/CHANGELOG.md` and `production/helm/loki/README.md`.

Kaviraj Kanagaraj	a550b767d3	config: Remove already deprecated `store.max-look-back-period`. (#11038) ... This is already been deprecated longback. Decided to remove in next versions of Loki Signed-off-by: Kaviraj <kavirajkanagaraj@gmail.com>	2 years ago
Salva Corts	cb39952309	Deprecated/Deleted Config Checker tool (#10977) ... **What this PR does / why we need it**: This PR adds a new _deprecated/deleted config checker_ tool to allow users upgrading from previous Loki versions to check their Loki config and runtime config for deprecated and deleted options, as well as providing them with alternatives and reasons why those configs were deprecated/deleted. Mimir provides a [tool][1] that allows users to migrate their old configs to new ones. Having that is our future goal but the new tool in this PR is a good middle ground for the short-mid term. We also update the checklist in the PR template to ask contributors to update the tool source of truth if the contributor is deprecating or deleting a config. Here's an example for how to use the tool: ```bash go run tools/deprecated-config-checker/main.go \ -config.file tools/deprecated-config-checker/test-fixtures/config.yaml \ -runtime-config.file tools/deprecated-config-checker/test-fixtures/runtime-config.yaml ``` And this is an example output:  ### Notes I think I've gone through all the deprecated and deleted configs. I cannot find the config pointed by the deprecated `ruler.storage`. It states ``` ruler: ... # Deprecated: Use -ruler-storage. CLI flags and their respective YAML config # options instead. storage: ... ``` I couldn't find that `-ruler-storage` cli flag nor the YAML definition.
