K-디지털트레이닝(빅데이터) 63일차

오늘은 도커에 관해 배웠다.

nohup note.sh &

ps -ef - 프로세스 목록
ps -ef | grep jupyter

ssh 192.168.159.3
hostnamectl set-hostname second

vi /etc/hosts

192.168.159.3 first
192.168.159.4 second

이렇게 하면 ssh second 해도 접속 가능

scp 192.168.159.3:/etc/hosts /etc/hosts

도커 그룹을 bigdata에 추가

docker ps

docker run hello-world (이미지 땡겨와서 컨테이너에 넣는다)

docker search hello-world

docker images (이미지 목록)

docker container ls

docker ps -a

다 지우기
docker rm -f $(docker ps -aq)

다시 시작
docker pull nginx:lastest

허브에 올리기

docker login

dbgusals1!

docker push y7y1h13/second_docker
아이디/도커이름 이렇게 만들어야한다.

검색할 때 로그아웃하고 해야함
docker pull allomyrina/whaleisgood

docker rm $(docker ps -a -q)

docker run allomyrina/whaleisgood

second에 도커 깔아놓기

(first) docker tag y7y1h13/xxx (ip)/y7y1h13/xxx

(second)docker pull (ip):5000/y7y1h13/xxx
