脚本宝典收集整理的这篇文章主要介绍了docker镜像实例，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、Nginx镜像
二、MySQL镜像
三、ssh镜像
四、Systemctl镜像
五、Tomcat镜像
一、Nginx镜像
mkdir /opt/nginx cd /opt/nginx/ cp /opt/nginx-1.12.0.tar.gz /opt/nginx From centos:7 MaiNTAINER SDY RUN yum -y update RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make RUN useradd -M -s /sbin/noLOGin nginx ADD nginx-1.12.0.tar.gz /usr/local/src WORKDIR /usr/local/src/nginx-1.12.0/ RUN ./configure --PRefix=/usr/local/nginx --user=nginx --group=nginx --wITh-http_stub_status_module RUN make && make install env PATH /usr/local/nginx/sbin:$PATH ExpOSE 80 EXPOSE 443 ADD nginx.service /lib/systemd/system/ RUN chmod 754 /lib/systemd/system/nginx.service RUN echo "daemon off;" >> /usr/local/nginx/conf/nginx.conf ADD rrun.sh /rrun.sh RUN chmod 755 /rrun.sh CMD ["/rrun.sh"] vim rrun.sh #!/bin/bash /usr/local/nginx/sbin/nginx //创建新镜像 docker build -t nginx:centos7 . docker run -d -P nginx:centos7 docker ps -a 5DF9e4383b96 nginx:centos "/rrun.sh" 15 seconds ago Up 15 seconds 0.0.0.0:32769->80/tcp, 0.0.0.0:32768->443/tcp silly_davinci http://192.168.91.5:32769
二、MySQL镜像
mkdir /opt/mysql cd /opt/mysql From centos:7 MAINTAINER SDY RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison @R_943_1512@ make RUN useradd -M -s /sbin/nologin mysql ADD mysql-boost-5.7.20.tar.gz /opt/mysql/ WORKDIR /opt/mysql/mysql-5.7.20 RUN cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DSYSCONFDIR=/etc -DSYSTEMD_PID_DIR=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ArchIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 -DMYSQL_DATADIR=/usr/local/mysql/data -DWITH_BOOST=boost -DWITH_SYSTEMD=1 && make -j2 && make install RUN rm -rf /etc/my.cnf ADD my.cnf /etc/my.cnf RUN chown -R mysql:mysql /usr/local/mysql/ RUN chown mysql:mysql /etc/my.cnf ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH WORKDIR /usr/local/mysql/bin/ RUN ./mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data RUN cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/ EXPOSE 3306 CMD ["/usr/sbin/init"] vim /etc/my.cnf [client] port = 3306 socket=/usr/local/mysql/mysql.sock [mysqld] user = mysql basedir=/usr/local/mysql datadir=/usr/local/mysql/data port = 3306 character-set-server=utf8 pid-file = /usr/local/mysql/mysqld.pid socket=/usr/local/mysql/mysql.sock bind-address = 0.0.0.0 skip-name-resolve max_connections=2048 default-storage-engine=INNODB max_Allowed_packet=16M server-id = 1 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES //创建新镜像 docker build -t mysql:centos7 . //启动容器，并进行初始化 docker run --name mysql1 -P --privileged -it -v /sys/fs/cgroup:/sys/fs/cgroup mysql:centos7 //进容器给权限 docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS names f9a4d8f6c65f mysql:centos "/usr/sbin/init" 17 seconds ago Up 16 seconds 0.0.0.0:49153->3306/tcp mysql1 //进入容器，授权远程连接 mysql docker exec -it f9a4d8f6c65f /bin/bash mysql -u root -p grant all privileges on *.* to 'root'@'%' identified by '411526'; grant all privileges on *.* to 'root'@'localhost' identified by '411526'; flush privileges; //在客户端连接mysql容器 mysql -h 192.168.91.5 -u root -P 49153 -p411526
三、ssh镜像
mkdir /opt/ssh cd /opt/ssh 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 <wl> #镜像的操作指令 RUN yum -y update RUN yum -y install openssh* net-tools lsof telnet passwd RUN echo '411526' | 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 && chmod 700 /root/.ssh EXPOSE 22 CMD ["/usr/sbin/sshd" , "-D"] //生成镜像 docker build -t ssh:centos7 . //启动容器并修改root密码 docker run -d -P ssh:centos7 docker ps -a ssh localhost -p 49155
四、systemctl镜像
mkdir /opt/systemctl cd /opt/systemctl vim Dockerfile FROM sshd:centos MAINTAINER this is systemctl image <wl> 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 &
五、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 SDY 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:centos7 . docker run -d --name tomcat01 -p 7321:8080 tomcat:centos7 http://192.168.91.5:7321
