2. docker file 만들기
# mkdir docker
# cd docker
# mkdir git-ssh
# cd git-ssh
# vi Dockerfile
FROM ubuntu:14.04
RUN apt-get -y update
RUN apt-get -y install openssh-server
RUN apt-get -y install git
# Setting openssh
RUN mkdir /var/run/sshd
RUN sed -i "s/#PasswordAuthentication yes/PasswordAuthentication no/" /etc/ssh/sshd_config
# Adding git user
RUN adduser --system git
RUN mkdir -p /home/git/.ssh
# Clearing and setting authorized ssh keys
RUN echo '' > /home/git/.ssh/authorized_keys
RUN echo 'ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDTFEBrNfpSIvgz7mZ+I96/UqKFCxcouoiDDS9/XPNB1Tn7LykgvHHaR5mrPOQIJ/xTFhSVWpwsmEvTLdv3QJYLB5P+UfrjY5fUmiYgGpKKr5ym2Yua2wykHgQYdT4+lLhyq3BKbnG9vgc/FQlaCWntLckJfAYnHIGYWl1yooMAOka0/pOeJ+hPF0TxLQtrjoVJWiaHLVnB8qgPiCgvSyKROvW6cs1AhY9abasUWrQ5eNsLLMY1rDWccantMjVlcUdDZuPzI4g+/MtfE3IAs7JxtmwMvCMFRMuzWTtZkZSVyqpEGDeLnPGgMNTYUwaxQhlJLtcYnNTqdyZr8ZCcz3zP stephen@Stephenui-MacBook-Pro.local' >> /home/git/.ssh/authorized_keys
# Updating shell to bash
RUN sed -i s#/home/git:/bin/false#/home/git:/bin/bash# /etc/passwd
EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]
# docker build -t git-ssh-img .
# docker run --name git-ssh -d -p 1234:22 git-ssh-img
3. docker container bash로 접속
# docker run -i -t --rm --net='host' ubuntu:14.04 bash
3. docker container 접속
# docker exec -it <containerIdOrName> bash
4. docker 모든 컨테이너 보기
# docker ps -a
5. 모든 컨테이너 삭제
# docker ps -a | awk '{print $1}' | grep -v CONTAINER | xargs sudo docker rm
6. docker 모든 <none> 이미지 삭제
# docker images | grep "<none>" | awk '{print $3}' | xargs sudo docker rmi
7. 이미지 조회 및 실행
$ sudo docker search ubuntu
$ sudo docker run --name myssh -d -p 4444:22 rastasheep/ubuntu-sshd
8. stack 사용자 docker 그룹 권한 추가
$ sudo usermod -aG docker stack
$ sudo service docker restart
$ 재로그인
9. docker 이미지 가져오기
$ docker pull ubuntu:lates
10. docker bash쉘로 실행 및 빠져나오기기
$ docker run -i -t --name hello ubuntu /bin/bash
root@bb97e5f57596:/#
Ctrl + p, Ctrl + q => 멈추지 않고 빠져나오기
$ docker attach hello => 다시 접속하기 (enter를 한번 쳐야 함)
11. nginx 설치하기
# mkdir data
# vi Dockerfile
FROM ubuntu:14.04.3
RUN apt-get update
RUN apt-get install -y nginx
RUN echo "\ndaemon off;" >> /etc/nginx/nginx.conf
RUN chown -R www-data:www-data /var/lib/nginx
VOLUME ["/data", "/etc/nginx/site-enabled", "/var/log/nginx"]
WORKDIR /etc/nginx
CMD ["nginx"]
EXPOSE 80
EXPOSE 443
# docker build -t nginx:0.1 .
# docker run --name hello-nginx -d -p 2080:80 -v /root/data:/data nginx:0.1
11. 파일 꺼내서 보기
# docker cp hello-nginx:/etc/nginx/nginx.conf ./
12. 컨테이러를 이미지로 생성
# docker commit -a "aaa <aaa@aaa.com>" -m "Initial commit" hello-nginx nginx:0.2
13. 이미지와 컨테이너 변경사항 보기
# docker diff 컨테이너ID
# docker history 이미지ID
14. 컨테이너 내부 보기
# docker inspect hello-nginx
15. docker 컨테이너의 pid 알아내기
$ docker inspect -f '{{.State.Pid}}' containerID
16. Docker 끼리 point to point 통신하기 (도커마다 네임스페이스를 만들어서 VETH 로 연결)
