docker使用笔记V -- FTP 与 SSH 支持
给容器赋予FTP和ssh登录在调试和使用阶段都是很不错的功能！下面看老高怎么实现的。
(基于ubuntu:xenial)
FTP
参考README.Configuration-File 和 Documentation for version 1.0.42
FROM ubuntu:xenial
RUN sed -i "s/archive\.ubuntu\.com/mirrors\.ustc\.edu\.cn/g" /etc/apt/sources.list
RUN apt-get update \
&& apt-get install -y wget build-essential \
&& rm -rf /var/lib/apt/lists/*
RUN wget https://download.pureftpd.org/pub/pure-ftpd/releases/pure-ftpd-1.0.42.tar.gz
RUN tar -xzf pure-ftpd-1.0.42.tar.gz
RUN cd /pure-ftpd-1.0.42; ./configure --with-everything --with-privsep --without-capabilities
RUN cd /pure-ftpd-1.0.42; make; make install
# 虚拟用户
RUN (echo 'laogao'; echo 'laogao') | pure-pw useradd www -u root -d /home/www
pure-pw mkdb
# 系统用户
RUN echo root:laogao |chpasswd
CMD ["/usr/local/sbin/pure-ftpd -p 40000:40009 -A -b -B -C 20 -D -E -H -j -4 -lpuredb:/etc/pureftpd.pdb"]
测试命令：
ftp 127.0.0.1
root
laogao
SSH
FROM ubuntu:xenial
RUN sed -i "s/archive\.ubuntu\.com/mirrors\.ustc\.edu\.cn/g" /etc/apt/sources.list
RUN apt-get update \
&& apt-get install -y openssh-server \
&& rm -rf /var/lib/apt/lists/*
#ssh
RUN mkdir /var/run/sshd
RUN echo 'root:screencast' | chpasswd
RUN sed -i 's/PermitRootLogin without-password/PermitRootLogin yes/' /etc/ssh/sshd_config
RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd
RUN sed -i 's/Port 22/Port 22222/' /etc/ssh/sshd_config
ENV NOTVISIBLE "in users profile"
RUN echo "export VISIBLE=now" >> /etc/profile
EXPOSE 22222
CMD ["/usr/sbin/sshd", "-D"]
测试命令
ssh [email protected] -p 22222
screencast
小贴士
你的服务器可能需要运行着防火墙，下面的命令可以帮你开启端口：
firewall-cmd --permanent --add-service=ssh
firewall-cmd --permanent --add-port=20-21/tcp
firewall-cmd --permanent --add-port=20000-20009/tcp
firewall-cmd --reload
