1、centos镜像的二次封装
docker build -t csphere/centos:7.1 .
FROM centos:centos7.1.1503 MAINTAINER Carson,C.J.Zeong <zcy@nicescale.com> ENV TZ "Asia/Shanghai" ENV TERM xterm ADD aliyun-mirror.repo /etc/yum.repos.d/CentOS-Base.repo ADD aliyun-epel.repo /etc/yum.repos.d/epel.repo RUN yum install -y curl wget tar bzip2 unzip vim-enhanced passwd sudo yum-utils hostname net-tools rsync man && \ yum install -y gcc gcc-c++ git make automake cmake patch logrotate python-devel libpng-devel libjpeg-devel && \ yum install -y --enablerepo=epel pwgen python-pip && \ yum clean all RUN pip install supervisor ADD supervisord.conf /etc/supervisord.conf RUN mkdir -p /etc/supervisor.conf.d && \ mkdir -p /var/log/supervisor EXPOSE 22 ENTRYPOINT ["/usr/bin/supervisord", "-n", "-c", "/etc/supervisord.conf"]
注意：这步很重要否则会导致后续的很多镜像构建出问题(每个镜像都有相互依赖)，建议不要“创新”否则会话更多的时间去修复“创新”
2、jdk1.8镜像
docker build -t csphere/jdk:1.8 .
docker run -d -p 18083:8083 --name jdk1.8 csphere/jdk:1.8
FROM csphere/centos:7.1 MAINTAINER 623196924@qq.com USER root ADD jdk1.8 /usr/local/jdk1.8 #安装jdk ENV JAVA_HOME /usr/local/jdk1.8 ENV JRE_HOME /usr/local/jdk1.8/jre ENV PATH $PATH:$JAVA_HOME/bin:$JRE_HOME/bin ENV CLASSPATH .:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
3、maven镜像
docker build -t csphere/maven:3.3.9 .
docker run -d -p 18081:8081 --name maven3.3.9 csphere/maven:3.3.9
FROM csphere/jdk:1.8 MAINTAINER lzhcode ENV MAVEN_VERSION 3.3.9 ENV MAVEN_HOME /usr/local/maven # Install maven # ADD http://mirror.cc.columbia.edu/pub/software/apache/maven/maven-3/${MAVEN_VERSION}/binaries/apache-maven-${MAVEN_VERSION}-bin.tar.gz /usr/local/ USER root RUN mkdir -p /usr/local/ COPY apache-maven-${MAVEN_VERSION}-bin.tar.gz /usr/local/apache-maven-${MAVEN_VERSION}-bin.tar.gz RUN cd /usr/local && \ tar -xvf apache-maven-${MAVEN_VERSION}-bin.tar.gz -C /usr/local && \ mv apache-maven-${MAVEN_VERSION} maven && \ rm -rf apache-maven-${MAVEN_VERSION}-bin.tar.gz RUN ln -s /usr/local/maven/bin/mvn /usr/bin/mvn && \ chmod 777 /usr/bin/mvn COPY settings.xml /usr/local/maven/conf/settings.xml ADD hello /hello RUN cd /hello && \ mvn clean install -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true
4、tomcat镜像
docker build -t csphere/tomcat:7.0 .
docker run -d -p 18082:8082 --name tomcat7.0 csphere/tomcat:7.0
FROM csphere/jdk:1.8 MAINTAINER lzhcode ENV TOMCAT_MAJOR_VERSION 7 ENV TOMCAT_MINOR_VERSION 7.0.68 ENV CATALINA_HOME /usr/local/tomcat7.0 ENV APP_DIR ${CATALINA_HOME}/webapps/ # Install tomcat # RUN wget -q https://archive.apache.org/dist/tomcat/tomcat-${TOMCAT_MAJOR_VERSION}/v${TOMCAT_MINOR_VERSION}/bin/apache-tomcat-${TOMCAT_MINOR_VERSION}.tar.gz RUN mkdir -p /usr/local/ COPY apache-tomcat-*.tar.gz /usr/local/apache-tomcat-${TOMCAT_MINOR_VERSION}.tar.gz RUN cd /usr/local && \ tar zxf apache-tomcat-${TOMCAT_MINOR_VERSION}.tar.gz && \ mv apache-tomcat-${TOMCAT_MINOR_VERSION} tomcat7.0 && \ rm -rf apache-tomcat-${TOMCAT_MINOR_VERSION}.tar.gz RUN cd ~/ ADD scripts /scripts RUN chmod -R 777 /scripts EXPOSE 8080 8443 ENTRYPOINT ["/scripts/run"] ONBUILD ADD . ${APP_DIR}
5、jenkins镜像
docker build -t csphere/jenkins:2.138 .
docker run -d -p 18080:8080 --name jenkins -v /usr/bin/docker:/usr/bin/docker -v /etc/sysconfig/docker:/etc/sysconfig/docker -v /run/docker.sock:/run/docker.sock -v /usr/local/docker-training/maven:/root csphere/jenkins:2.138
# # MAINTAINER Carson,C.J.Zeong <zcy@nicescale.com> # DOCKER-VERSION 1.6.2 # # Dockerizing Jenkins: Dockerfile for building Jenkins images # FROM csphere/jdk:1.8 MAINTAINER Carson,C.J.Zeong <zcy@nicescale.com> ENV JENKINS_HOME /var/jenkins_home ENV JENKINS_VERSION 2.138 ENV JENKINS_UC https://updates.jenkins-ci.org ENV COPY_REFERENCE_FILE_LOG /var/log/copy_reference_file.log RUN mkdir -p /usr/share/jenkins/ref/init.groovy.d && \ mkdir -p $JENKINS_HOME COPY init.groovy /usr/share/jenkins/ref/init.groovy.d/tcp-slave-agent-port.groovy COPY jenkins.war /usr/share/jenkins/jenkins.war RUN chown -R root "$JENKINS_HOME" /usr/share/jenkins/ref && \ touch $COPY_REFERENCE_FILE_LOG && chown -R root $COPY_REFERENCE_FILE_LOG VOLUME /var/jenkins_home EXPOSE 8080 50000 COPY jenkins.sh /usr/local/bin/jenkins.sh RUN chmod +x /usr/local/bin/jenkins.sh ENTRYPOINT ["/usr/local/bin/jenkins.sh"]
5.1手动构建 jenkins镜像
出现的问题：
1.You don't have either docker-client or docker-client-latest installed. Please install either one and retry.
docker默认要在docker用户下才能运行，刚开始使用了jenkins用户结果无法运行docker命令
2.切到root用户后仍然提示上面的语句，原来是没有安装docker-client 执行进入容器执行
yum clean all && yum swap fakesystemd systemd
yum install docker-client
应该是centos的版本比较旧的原因，提交centos7.1镜像前先执行这两句
3.最新的jenkins2.138下好像没有docker client命令行工具（知道原因的同学欢迎指正），因此我们只需要传递DOCKER_HOST环境变量 或者映射docker.sock文件给jenkins容器，就可以让jenkins容器里面拥有docker的操作能力，进而将两者结合起来。
4.Rpmdb checksum is invalid: dCDPT(pkg checksums): sudo.x86_64 0:1.8.6p3-29.el6_9 - u
rpm数据库损坏需要重建。因此需要在 “yum install …” 前使用“rpm –rebuilddb” 重建数据库。比如：
RUN rpm --rebuilddb && yum install -y sudo ...
