Docker中使用Dockerfile生成ssh服務

02-03

（1）第一步：

本機上使用「ssh-keygen -t rsa」,將「/root/.ssh/id_rsa.key「裡面的內容複製到authorized_keys中，並拷貝至當前目錄下。

（2）第二步：

書寫Dockerfile：

FROM ubuntu:14.04nnMAINTAINER from sonnynn#RUN echo "deb http://mirrors.163.com/ubuntu/ wily main restricted universe multiverse" > /etc/apt/sources.listn#RUN echo "deb http://mirrors.163.com/ubuntu/ wily-security main restricted universe multiverse" > /etc/apt/sources.listn#RUN echo "deb http://mirrors.163.com/ubuntu/ wily-updates main restricted universe multiverse" > /etc/apt/sources.listn#RUN echo "deb http://mirrors.163.com/ubuntu/ wily-proposed main restricted universe multiverse" > /etc/apt/sources.listn#RUN echo "deb http://mirrors.163.com/ubuntu/ wily-backports main restricted universe multiverse" > /etc/apt/sources.listn#RUN echo "deb-src http://mirrors.163.com/ubuntu/ wily main restricted universe multiverse" > /etc/apt/sources.listn#RUN echo "deb-src http://mirrors.163.com/ubuntu/ wily-security main restricted universe multiverse" > /etc/apt/sources.listn#RUN echo "deb-src http://mirrors.163.com/ubuntu/ wily-updates main restricted universe multiverse" > /etc/apt/sources.listn#RUN echo "deb-src http://mirrors.163.com/ubuntu/ wily-proposed main restricted universe multiverse" > /etc/apt/sources.listn#RUN echo "deb-src http://mirrors.163.com/ubuntu/ wily-backports main restricted universe multiverse" > /etc/apt/sources.listnnRUN apt-get updatennRUN apt-get install -y openssh-servernnRUN mkdir -p /var/run/sshdnnRUN mkdir -p /root/.sshnnRUN sed -ri s/session required pam_loginuid.so/#session required pam_loginuid.so/g /etc/pam.d/sshdnnADD authorized_keys /root/.ssh/authorized_keysn#ADD id_rsa /root/.ssh/id_rsan#ADD id_rsa.pub /root/.ssh/id_rsa.pubnADD known_hosts /root/.ssh/known_hostsnnADD run.sh /run.shnRUN chmod 755 /run.shnnEXPOSE 22nCMD ["/run.sh"]n

上面的指令，不多說了！

run.sh代碼內容：

#!/bin/bashnn/usr/sbin/sshd -Dn

使用docker build -t sshd:dockerfile . 指令執行後生成docker鏡像。

在後台啟動docker鏡像，」docker run -d -p 10022:22 sshd:dockerfile「，如果正常啟動時，則可以看到

現在測試一下：

使用：」ssh 127.0.0.1 -p 10022「,如果出現下列，則啟動成功：
