Docker Notes

TLDR

When you've a dockerfile, you must build and run it to make use of it.

• Dockerfile will make sure we build a container, to setup a OS for our application. This is also where we can setup network to our other containers

• Docker-composer can automate our docker build and boot up our containers. This makes it easy, if we are dependent on other containers and if there are multiple.

Docker

Show all running containers

docker ps

Stop specified container

docker stop $id

Start specified container

docker run $id

Start container with open ports and interactive mode

docker run -it -p 3000:3000 CONTAINER_ID

Start container with volumes (reference to our own current folder)

docker run -it -p 3000:3000 CONTAINER_ID

Start container with volumes - preserve node_modules - active watcher for changes

docker run -it -p 3000:3000 -v /app/node_modules -v /c/Users/username/frontend:/app -e CHOKIDAR_USEPOLLING=true CONTAINER_ID

Start container without enviroment variable (can be added to package.json if react)

docker run -it -p 3000:3000 -v /app/node_modules -v C:\Users\Jacob\GithubProjects\reactContainer\frontend:/app twizzx/reactdevelopment

Ssh to running container (depends on OS)

docker exec -it 2d7bc51163a2 /bin/sh
