Stop container

docker stop id → Stop docker container by container id
docker stop name → Stop docker container by container name

Start container

docker start id → Start docker container by container id
docker start name → Start docker container by container name
docker start -i name → Start docker and see logs

Logs container

docker logs id → Logs docker container by container id
docker logs name → Logs docker container by container name

Remove container

docker rm id → Remove docker container by container id
docker rm name → Remove docker container by container id

-f

docker rm -f id → Force stop and remove docker container by container id
docker rm -f name → Force stop and remove docker container by container id

Copy container file or folder to other folder

docker cp node_container:/app/app.js ./copy/ → Copy the file app.js to a local folder copy

Get informations docker container

docker top container → See informations about container
docker inspect container → See id, createdData, image, etc
docker stats → See how many memory, cpu and some informations about every containers

Images

Dockerfile

FROM → Base image
WORKDIR → Application directory
EXPOSE → Application port
COPY → Files that need to be copied

Example:

FROM node

WORKDIR /app

COPY package*.json .

RUN npm install

COPY . .

EXPOSE 3000

CMD ["node", "app.js"]

docker build . → Build Dockerfile "docker build (root of Dockerfile)"
docker run -d -p 3000:3000 --name my_node id → Run Dockerfile
docker run -d -p 3000:3000 --name my_node name → Run Dockerfile
docker run -d -p 3000:3000 --name my_node --rm name → Run Dockerfile and when stop it is removed

See images

docker image ls → See images
docker images → See images

Dowloading image

docker pull python → Dowload python

Name for image

docker tag id name:tag → Change name and tag image
docker build -t name:tag . → Build with name and tag

Remove image

docker rmi name → Remove image by name
docker rmi id → Remove image by id
docker systmem prune → Remove all containers, images and networks that are't being used

Docker commands

docker login → Login to docker
docker logout → Logout docker

-docker build -t 17102003/first_image_node . → Get image to docker hub
