I have created 2 containers mongo express and mongo db containers using below commands

docker run -dit -p 27017:27017 -e MONGO_ROOT_USERNAME=admin -e MONGO_INTDB_ROOT_PASSWORD=password -e PWD=/ -v mongodb-data:/data/db --name mongodb_1 --net my_bridge mongo

docker run -dit -p 8081:8081 -e ME_CONFIG_MONGODB_ADMINUSERNAME=admin -e ME_CONFIG_MONGODB_ADMINPASSWORD=password --net my_bridge --name mongo_express_1 -e ME_CONFIG_MONGODB_SERVER=mongodb_1 -e ME_CONFIG_BASICAUTH_USERNAME=admin -e ME_CONFIG_BASICAUTH_PASSWORD=admin123456 mongo-express

But I am not able to open application you can see , please suggest what could be the issue

Use 3 backticks before and after code/config to make it more readable and preserve spacing.

When running a container on the same host with docker run -p <port> …, you would usually access it from the host OS with localhost:<port>.

That is what I have tried but I can see not reachable error

I added the windows tags, are you using Docker Desktop or WSL?
