[Docker] CentOS 7 Dockerfile

 

 

docker 에서 곧바로 centos 7 이미지를 가져오면

docker pull centos:7

내부에서 문제가 좀 많음

문제가 없는 centos 7 은 아래 Dockerfile 을 만들어서 직접 build 해서 만듦

 

FROM centos:7
ENV container docker
RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == \
systemd-tmpfiles-setup.service ] || rm -f $i; done); \
rm -f /lib/systemd/system/multi-user.target.wants/*;\
rm -f /etc/systemd/system/*.wants/*;\
rm -f /lib/systemd/system/local-fs.target.wants/*; \
rm -f /lib/systemd/system/sockets.target.wants/*udev*; \
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \
rm -f /lib/systemd/system/basic.target.wants/*;\
rm -f /lib/systemd/system/anaconda.target.wants/*;
VOLUME [ "/sys/fs/cgroup" ]
CMD ["/usr/sbin/init"]

 

< build 명령어 > $ docker build -t mycentos:7 .

 

< run 명령어 > $ docker run --name mycentos7 --privileged -d mycentos:7 init
