docker command

docker ps filter

docker ps -f "name=minio*"

docker reset

git reset --hard

docker-compose fast

export DOCKER_BUILDKIT=1 # or configure in daemon.json
export COMPOSE_DOCKER_CLI_BUILD=1
COMPOSE_DOCKER_CLI_BUILD=1 docker-compose build

dockerhub login

docker login --username=yknam
docker tag node365(local) yknam/node365:latest(remote)
docker push yknam/node365:latest


docker run -d -P -v $HOME/mysite:/usr/s
hare/nginx/html --name mysite nginx
docker port mysite

docker-compose up,build,no-build

docker-compose build 		: 이미지만 생성
docker-compose up 		   : 컨테이너실행 (이미지 없으면 생성)
docker-compose up --build --no-deps: 기존 이미지사용않고 새로 이미지생성 후 컨테이너실행
docker-compose up --build    : 강제로 이미지생성 후 컨테이너실행
docker-compose up --no-build : 이미지생성없이 컨테이너실행

모든 컨테이너 삭제

docker rm -f $(docker ps -aq)

directory size

du -hs <dir>

네트워크 생성

docker network create --driver=bridge javahome
doekcer network ls

네트워크로 묶기

docker run -itd --name=alpine1 --network=javahome alpine
docker run -itd --name=alpine2 --network=javahome alpine
docker network inspect javahome
docker attach alpine1
->ping <container ip>
->ping alpine2 (컨테이너명으로도 핑됨)

도커 ENTRYPOINT vs CMD

[CMD]
FROM ubuntu:16.04
CMD echo 'welcome to docker'
CMD echo 'welcome to python'
->docker build -t app .
docker run -it <containerid> -->마지막것만 실행됨

[ENTRYPOINT]
FROM ubuntu:16.04
ENTRYPOINT["echo", "hi docker"]
