 ```
+
+#### Option 2: Use local tar.gz file
+
+To use a locally built tar.gz file:
+
+1. Build Ops Manager (if it fails look into [this wiki](https://wiki.corp.mongodb.com/spaces/MMS/pages/314679084/Ops+Manager+Development+-+Working+with+Build+Systems))
+
+    ```bash
+    cd ${MMS_HOME}
+    bazel build --cpu=amd64 --build_env=tarball //server:package
+    ```
+
+2. Copy your local tarball to the docker directory:
+
+    ```bash
+    cp ${MMS_HOME}/bazel-bin/server/package.tar.gz docker/mongodb-enterprise-ops-manager/
+    ```
+
+3. Build using the local tarball:
+    ```bash
+    VERSION="local-build"
+    docker buildx build --load --progress plain --platform linux/amd64 . -f docker/mongodb-enterprise-ops-manager/Dockerfile -t "mongodb-enterprise-ops-manager:${VERSION}" \
+      --build-arg version="${VERSION}" \
+      --build-arg use_local_tarball=true
+    ```
