Docker commands

Images

Build docker image

docker build -t test-image-name .

Run image in interactive mode

docker run -it -p 7777:7777 test-image-name

Or run image in silent(daemon) mode

docker run -d -p 7777:7777 test-image-name

List all images

docker image ls

Remove all images at once

docker rmi $(docker images -q)

Containers

List all active containers

docker ps

List all active and dead containers

docker ps -a

Stop all running containers

docker stop $(docker ps -a -q)

Delete all stopped containers:

docker rm $(docker ps -a -q)

Other

Install help utils

apt-get install iputils-ping nmap

Jump into container shell

docker exec -it CONTAINER_ID /bin/sh

why you copied # copy configs to /app folder if you not npm install after? Usually we copy configs and then run npm install and then we copy code. In that order we can use docker cached layer for npm install command. In dockerfile above you will npm install every time when your code changed..

@Edr2 you're right... it should rather be

COPY package*.json .
npm install

🙏

Nice project
