docker容器_自定义上传jenkins镜像(Dockerfile实现)

1.创建jenkins目录，并上传相应的包

mkdir  /jenkins/  

 2.创建一个Dockerfile文件

FROM daocloud.io/library/centos:7

#把当前目录下的jenkins.war包传到内部容器的/ 下
ADD ./jenkins.war /

#把当前目录下的jdk传到内部容器的/opt/,并解压
ADD ./jdk-11.0.19_linux-x64_bin.tar.gz /opt

RUN curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
RUN yum clean all
RUN yum repolist
RUN yum -y install fontconfig

#配置java环境
ENV JAVA_HOME=/opt/jdk-11.0.19
ENV PATH=${JAVA_HOME}/bin:${PATH}

#启动jenkins命令
CMD [ "java","-jar","/jenkins.war" ]

3.构建jenkins镜像

docker build -t jenkins:1.0 .

4. 构建jenkins镜像过程

5.查看镜像

#-e 指定环境， -v 映射本地目录到容器里，-p 映射本地端口到容器 
docker run -it  -e JENKINS_HOME=/opt/.jenkins -v ./plugins:/opt/.jenkins/plugins -p 8080:8080 jenkins:1.0

7.查看正在运行的容器
