Prerequisites:
- Install Docker for Windows
- Make sure you use Linux Containers for this example
- I used Visual Studio Code as development IDE
Build docker image
docker build -t balab2020/node-web-app .
balab2020/node-web-app is docker image name
Run Docker Image
docker run -p 49160:8080 -d balab2020/node-web-app
-d runs the container in detached mode -p flag redirects a public port to a private port inside the container
49160 is the system ip mapped with docker instance 8080 ip
List running images
docker ps
Sample Output:
| CONTAINER ID | IMAGE NAMES | COMMAND | CREATED | STATUS | PORTS |
|---|---|---|---|---|---|
| c249cfa8fd79 | balab2020/node-web-app | "npm start" | 35 seconds ago | Up 18 seconds | 0.0.0.0:49160->8080/ |
Connect to docker instance
docker exec -it CONTAINER_ID bash
Display logs of container
docker logs CONTAINER_ID
Check running instance service
curl -i localhost:49160
