Dockerfile 镜像实战（构建 SSH、Systemctl、Tomcat、Mysql 镜像）

发布时间：2022-07-02 发布网站：脚本宝典

脚本宝典收集整理的这篇文章主要介绍了Dockerfile 镜像实战（构建 SSH、Systemctl、Tomcat、Mysql 镜像），脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。

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 <abc>
#镜像的操作指令
RUN yum -y update
RUN yum -y install oPEnssh* net-tools lsof telnet passwd
RUN echo 'abc123' | 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 '/^sessions+requireds+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 root.root /root &amp;& chmod 700 /root/.ssh
ExpOSE 22
CMD ["/usr/sbin/sshd" , "-D"]
 
 
//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 49153

二、构建 Systemctl 镜像

mkdir /opt/systemctl
cd /opt/systemctl
 
vim Dockerfile
 
From sshd:centos
MAINTAINER this is systemctl image <ABC>
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 -it -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 -d -P --privileged sshd:centos /usr/sbin/init &

三、构建 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 <XXX>
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 tomcat1 -p 1111:8080 tomcat:centos
  
http://20.0.0.6:1111

四、构建 MySQL 镜像

mkdir /opt/mySQLd
cd /opt/mysqld
 
vim Dockerfile
 
FROM centos:7
MAINTAINER this is mysql image <ly>
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison @R_996_1512@ make
