 You will also need a MongoDB instance to use this sample. If you have Docker installed, you can use the following:
 
 ```
-docker build -t liberty_mongo mongo
-docker run --name liberty_mongo -d -p 27017:27017 liberty_mongo
+docker run -d --name liberty_mongo -p 27017:27017 -e MONGO_INITDB_ROOT_USERNAME=sampleUser -e MONGO_INITDB_ROOT_PASSWORD=openliberty mongo:7.0.7
 ```
