1、centos镜像的二次封装
docker build -t csphere/centos:7.1 .
docker build -t csphere/centos:7.1 .
FROM centos:centos7.1.1503
MAINTAINER Carson,C.J.Zeong
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

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

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

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

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jenkins
2.138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 ...
