📝 Walkthrough

Walkthrough

Keeper now mounts an EmptyDir volume for logs. The SeaweedFS S3 gateway now mounts writable temporary storage at /tmp. Tests verify both pod configurations.

Changes

Runtime storage configuration

Layer / File(s)	Summary
Keeper log volume internal/controller/infra/managed/clickhouse/altinity/keeper/values.go, internal/controller/infra/managed/clickhouse/altinity/keeper/spec.go, internal/controller/infra/managed/clickhouse/altinity/keeper/spec_test.go	Keeper defines log volume constants, adds an EmptyDir volume and mount, and verifies the generated pod specification.
SeaweedFS temporary volume internal/controller/infra/managed/objectstore/seaweedfs/spec.go, internal/controller/infra/managed/objectstore/seaweedfs/spec_test.go	SeaweedFS S3 receives the writable temporary volume and /tmp mount. Tests verify the configuration.
