-# Deploy StreamPark on Docker
 
-### 1. docker-compose up
+### 1. Confirm release version
+When releasing the new version, the release manager will verify the image tag and push the image to the image repository,
+The latest image tag will be written to [docker-compose.yaml](./docker-compose.yaml),users also can independently verify whether the version of the StreamPark image in the [docker-compose.yaml](./docker-compose.yaml) file is correct (If the current branch has not been released, the image tag is the last release image tag):
+
+```yaml
+version: '3.8'
+services:
+    streampark-console:
+        image: apache/streampark:2.1.4
