支持ssh+nginx+進程自啓的dockerfile
--------Dockerfile 1 -------------------------------------------------------------------------------------------
在同一目錄下編寫Dokerfile文件，以及提前copy authorized_keys 文件，支持ssh驗證，yum源如果下載不了自己配置源
vim Dockerfile
FROM centos:latest
MAINTAINER xiaoxue [email protected]
run rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
RUN yum install -y nginx openssh-server sudo net-tools
RUN ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
RUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
RUN ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key
RUN ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key
ADD authorized_keys /root/.ssh/authorized_keys
#同一目錄下提前放置authorized_keys文件
RUN echo -e "#!/bin/sh \n/usr/sbin/sshd \n /usr/sbin/nginx -g 'daemon off;' " > /a.sh
#在配置entrypoint時候，最後一個進程要後臺運行，也就是守護進程關閉，如果sshd在最後加-D
run chmod +x /a.sh
EXPOSE 80 22
#CMD ["/usr/sbin/nginx","-g","daemon off;"]
ENTRYPOINT ["/a.sh"]然後你就執行下面兩行
docker build -t nginx:1.1 .
docker run --name container1 -dit -p8080:80 -p2222:22 nginx:1.1
docker restart container1
試試容器重啓是不是nginx開啓，ssh可以連接了，ok。。。
如果你想支持systemctl，參考這個。
