 ## Add replicas
 
-When adding replicas for `gitserver`, `indexed-search`, `searcher`, or `symbols`, you must update the corresponding environment variable on each of the frontend services in your docker-compose.override.yaml file, `SRC_GIT_SERVERS`, `INDEXED_SEARCH_SERVERS`, `SEARCHER_URL`, and `SYMBOLS_URL` to the number of replicas for each respective service. Sourcegraph will then automatically infer the endpoints for each replica.

+# Running Sourcegraph Without Kubernetes Service Discovery
+
+<Callout type="warning">Not settting these environment variables might prevent pods from starting when running without service discovery.</Callout>
+
+If you are deploying Sourcegraph in an environment **without Kubernetes service discovery** (for example, using Docker Compose or single-container Docker), you must manually configure the frontend service to know about the other service replicas. This is typically required when you are not using RBAC, or when running outside Kubernetes entirely.

+## Required Environment Variables
+
+- INDEXED_SEARCH_INDEXER
+- INDEXED_SEARCH_SERVERS
+- SEARCHER_URL
+- SRC_GIT_SERVERS
+- SYMBOLS_URL
+
+For detailed instructions on how to set these environment variables in a Docker Compose deployment, see the [Docker Compose configuration guide](/admin/deploy/docker-compose/configuration#set-environment-variables).
