Dockerfile构建镜像实战（SSH、systemctl、nginx、tomcat、mysql镜像）
一、构建SSH镜像
mkdir /opt/sshd
cd /opt/sshd
vim Dockerfile
#第一行必须指明基于的基础镜像
FROM centos:7
#作者信息
MAINTAINER this is ssh image <wdc>
#镜像的操作指令
RUN yum -y update
RUN yum -y install openssh* net-tools lsof telnet passwd
RUN echo 'abc1234' | passwd --stdin root
RUN sed -i 's/UsePAM yes/UsePAM no/g' /etc/ssh/sshd_config #不使用PAM认证
RUN sed -ri '/^session\\s+required\\s+pam_loginuid.so/ s/^/#/' /etc/pam.d/sshd #取消pam限制
RUN ssh-keygen -t rsa -A #生成密钥认证文件
RUN mkdir -p /root/.ssh && chown roiot.root /root && chmod 700 /root/.ssh
EXPOSE 22
CMD ["/usr/sbin/sshd"，"-D"] #/usr/sbin/sshd -D用于前台启动sshd服务
//生成镜像
docker build -t sshd:centos .
//启动容器并修改root密码
docker run -d -p sshd:centos
docker ps -a
ssh localhost -p 49155
二、生成Systemctl镜像
mkdir /opt/systemctl
cd /opt/systemctl
vim Dockerfile
FROM sshd:centos
MAINTAINER this is systemctl image <wdc>
ENV container docker
#除了systemd-tmpfiles-setup.service,删除其它所有文件
RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == systemd-tmpfiles-setup.service ] || rm -f $i;done); \\
rm -f /lib/systemd/system/multi-user.target.wants/*; \\
rm -f /etc/systemd/system/*.wants/*; \\
rm -f /lib/systemd/system/local-fs.target.wants/*; \\
rm -f /lib/systemd/system/sockets.target. wants/*udev*; \\
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \\
rm -f /lib/systemd/system/basic.target.wants/*;\\
rm -f /lib/systemd/system/anaconda.target.wants/*;
VOLUME [ "/sys/fs/cgroup" ]
#CMD ["/usr/sbin/init"]
//生成镜像
docker build -t systemd:centos
//启动容器，并挂载宿主机目录挂载到容器中，和进行初始化
docker run --privileged -d -P -v /sys/fs/cgroup:/sys/fs/cgroup:ro systemd:centos /sbin/init
#--privileged:使container内的root拥有真正的root权限。否则，container内的root只是外部的一个普通用户权限。
docker ps -a
//进入容器
docker exec -it a0d624d2bfa9 bash
systemctl status sshd
方法二：
docker run --privileged -it -P -v /sys/fs/cgroup:/sys/fs/cgroup:ro systemd:centos /sbin/init &
三、nginx镜像
mkdir /opt/nginx
cd /opt/nginx/
cp /opt/nginx-1.12.0.tar.gz /opt/nginx
vim Dockerfile
#基于基础镜像
FROM centos:7
#用户信息
MAINTAINER this is nginx image <wdc>
#添加环境包
RUN yum -y update
RUN yum -y install pcre-devel zlib-devel gcc gcc-C++ make
RUN useradd -M -s /sbin/ nologin nginx
#上传nginx软件压缩包，并解压
ADD nginx-1.12.0.tar.gz /opt/
#指定工作目录
WORKDIR /opt/nginx-1.12.0
RUN ./ configure \\
--prefix=/usr/local/nginx \\
--user=nginx \\
--group=nginx \\
--with-http_stub_status_module && make && make install
ENV PATH /usr/local/nginx/sbin:$PATH
#指定http和https端口
EXPOSE 80
EXPOSE 443
RUN echo "daemon off;" >> /usr/local/nginx/conf/nginx.conf #关闭nginx 在后台运行
#添加宿主机中run.sh到容器中
ADD run.sh /run.sh
RUN chmod 755 /run.sh
CMD ["/run.sh"]
vim run.sh
#!/bin/bash
/usr/local/nginx/sbin/nginx
docker ps -a

四、tomcat 镜像
mkdir /opt/tomcat
cd /opt/tomcat
cp /opt/jdk-8u91-linux-x64.tar.gz /opt/tomcat
cp /opt/apache-tomcat-8.5.16.tar.gz /opt/tomcat
vim Dockerfile
FROM centos:7
MAINTAINER this is tomcat image <wdc>
ADD jdk-8u91-linux-x64.tar.gz /usr/local/
WORKDIR /usr/local/
RUN mv jdk1.8.0_91 /usr/local/java
ENV JAVA_HOME /usr/local/java
ENV JRE_HOME $JAVA_HOME/jre
ENV CLASSPATH .:$JAVA_HOME/lib:$JRE_HOME/lib
ENV PATH $JAVA_HOME/bin:$PATH
ADD apache-tomcat-8.5.16.tar.gz /usr/local/
WORKDIR /usr/local/
RUN mv apache-tomcat-8.5.16 /usr/local/tomcat
EXPOSE 8080
#CMD ["/usr/local/ tomcat/bin/catalina.sh","run"]
ENTRYPOINT ["/usr/local/tomcat/bin/catalina.sh","run"]
//创建新镜像
docker build -t tomcat:centos .
docker run -d --name tomcat01 -p 1216:8080 tomcat:centos
