+## demo with mongo and mongo-express
+
+### 1 architecture diagram
+
+![architecture](architecture.png)
+
+### 2 with docker command
+
+1. create bridge network for container communication
+
+```shell
+docker network create mongo-network
+```
+
+![network-created](network-created.png)
+
+2. ls current network created
+
+```shell
+docker network ls
+```
+![network-ls](network-ls.png)
+
+3. run mongo over mongo-network
+
+```shell
+docker run -d \
+-p 27017:27017 \
+-e MONGO_INITDB_ROOT_USERNAME=admin \
+-e MONGO_INITDB_ROOT_PASSWORD=supersecret \
+--network mongo-network \
+--name mongodb \
+mongo
+```
+

+
+![mongo-container](mongo-container.png)
+
+4. run mongo-express over mongo-network
+
+```shell
+docker run -d \
+-p 8081:8081 \
+-e ME_CONFIG_MONGODB_ADMINUSERNAME=admin \
+-e ME_CONFIG_MONGODB_ADMINPASSWORD=supersecret \
+-e ME_CONFIG_MONGODB_SERVER=mongodb \
+--network mongo-network \
+--name mongo-express \
+mongo-express
+```
+

+
+### 3 with docker-compose 
+
+1. create docker-compose.yml
+
+```yaml
+networks:
+  mongo-network:
+    driver: bridge
+    name: mongo-network
+services:
+  mongodb:
+    image: mongo:latest
+    container_name: mongodb
+    environment:
+      MONGO_INITDB_ROOT_USERNAME: admin
+      MONGO_INITDB_ROOT_PASSWORD: supersecret
+    networks:
+      - mongo-network
+    ports:
+      - 27017:27017
+    healthcheck:
+      test: echo 'db.runCommand("ping").ok' | mongosh mongodb://admin:supersecret@localhost:27017/ --quiet
+      interval: 5s
+      timeout: 10s
+      retries: 3
+  mongo-express:
+    image: mongo-express:latest
+    container_name: mongo-express
+    environment:
+      ME_CONFIG_MONGODB_ADMINUSERNAME: admin
+      ME_CONFIG_MONGODB_ADMINPASSWORD: supersecret
+      ME_CONFIG_MONGODB_SERVER: mongodb
+    depends_on:
+      mongodb:
+        condition: service_healthy
+    networks:
+      - mongo-network
+    ports:
+      - 8081:8081 
+```
+
+2. use docker compose command to start
+```shell
+docker compose up -d
+```
