Ashwanth	98d1307c7d	config: ensure storage config defaults apply to named stores (#9650) ... **What this PR does / why we need it**: Since named store config does not register any flags, storage configs defined under it do not get the defaults. For example [aws_storage_config](https://grafana.com/docs/loki/latest/configuration/#aws_storage_config) sets the default `storage_class` to `STANDARD`, but the same doesn't get applied by default when using named stores. This PR ensures that named storage configs are always assigned default values when they are unmarshalled by implementing `yaml.Unmarshaler` interface	3 years ago
Ashwanth	b3e038c7a8	config_wrapper: Add support for named stores (#7946) ... Signed-off-by: Ashwanth Goli <iamashwanth@gmail.com> **What this PR does / why we need it**: This PR adds support for named stores which allows users to define multiple object store configurations for a storage type. Named stores can be referred to from other sections of the config similar to how provider type is being used `i.e aws, gcs...`. Named store reference should be of the format: `<store_type>.<key_name>` Below is an example configuration with two named stores defined for aws `store-1, store-2`. Schema config is referring to one of them as `aws.store-1` ``` storage_config: aws: endpoint: s3://common-bucket region: us-east1 access_key_id: abc123 secret_access_key: def789 named_stores: aws: store-1: endpoint: s3://foo-bucket region: us-west1 access_key_id: 123abc secret_access_key: 789def store-2: endpoint: s3://bar-bucket region: us-west2 access_key_id: 456def secret_access_key: 789abc schema_config: configs: - from: "2020-07-31" index: period: 24h prefix: loki_prod_index_ object_store: aws.store-1 schema: v11 store: boltdb-shipper ``` **Which issue(s) this PR fixes**: Fixes #7276 **Special notes for your reviewer**: Configuration defined in common storage config has no effect on the named stores. Common storage config only overrides storageConfig if it's not explicitly set - same behavior as before. This should be a non-intrusive change.

Susana Ferreira	d086c237df	Add missing period_config root block to doc generator (#7981) ... **What this PR does / why we need it**: Update doc generator tool to validate if slice element is a root block. Add missing `period_config` root block to doc generator tool. **Special notes for your reviewer**: **Checklist** - [ ] Documentation updated	3 years ago
Susana Ferreira	f93b91bfb5	Add configuration documentation generation tool (#7916) ... **What this PR does / why we need it**: Add a tool to generate configuration flags documentation based on the flags properties defined on registration on the code. This tool is based on the [Mimir doc generation tool](https://github.com/grafana/mimir/tree/main/tools/doc-generator) and adapted according to Loki configuration specifications. Prior to this PR, the configuration flags documentation was dispersed across two sources: * [_index.md](5550cd65ec/docs/sources/configuration/_index.md) * configuration flags registration in the code This meant that there was no single source of truth. In this PR, the previous `_index.md` file is replaced with the new file generated by the tool. The next step includes adding a CI step that validates if the _index.md file was generated according to the flags settings. This will be done in a follow-up PR. **NOTE:** this is not a documentation update PR. Apart from some minor typo fixes, the documentation changes on the code, were copied from the `_index.md` file. **Which issue(s) this PR fixes**: Fixes https://github.com/grafana/loki-private/issues/83 **Special notes for your reviewer**: Files: * [docs/sources/configuration/index.template](5550cd65ec/docs/sources/configuration/index.template): template used to generate the final configuration file * [/docs/sources/configuration/_index.md](c32e5d0acb/docs/sources/configuration/_index.md): file generated by tool * `loki/pkg` directory files updated with up-to-date documentation from `_index.md` file * [tools/doc-generator](5550cd65ec/tools/doc-generator) directory with documentation generation tool. **Checklist** - [ ] Reviewed the `CONTRIBUTING.md` guide - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md`	3 years ago
