一、背景

由于公司的jenkins运行在k8s集群中，在jenkins打包时调用jenkins-slave 来工作，所以需先构建android-jenkins-slave镜像。

jenkins-slave 在打包过程中会用到gradle和sdk，那么就牵涉到gradle插件和sdk持久化。

Android打包对资源要求较高，也可以单独建立jenkins工作节点，将Android打包调度到物理机节点进行。

二、NFS存储

//安装NFS服务端[root@nfs-server ~]# yum install -y nfs-utils[root@nfs-server ~]# mkdir -p /data/android[root@nfs-server ~]# mkdir -p /data/gradle[root@nfs-server ~]# vi /etc/exports/data/android 192.168.10.0/24(rw,no_root_squash)/data/gradle 192.168.10.0/24(rw,no_root_squash)[root@nfs-server ~]# systemctl enable rpcbind.service[root@nfs-server ~]# systemctl enable nfs-server.service[root@nfs-server ~]# systemctl start rpcbind.service[root@nfs-server ~]# systemctl start nfs-server.service[root@nfs-server ~]# exportfs -r//可能存在NFS无法访问，需提高权限[root@nfs-server ~]# chmod -R 777 /data/android /data/gradle

三、android-jenkins-slave镜像的Dockerfile

[root@mayi-ops jenkins-slave-android]# vim DockerfileFROM centos:7LABEL maintainer dengyouchengCOPY jdk-8u261-linux-x64.rpm /optCOPY gradle-6.7.1-all.zip /optCOPY sdk-tools-linux-3859397.zip /opt COPY slave.jar /usr/share/jenkins/slave.jarCOPY jenkins-slave /usr/bin/jenkins-slave#initRUN yum -y install wget && mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak && wget -O /etc/yum.repos.d/CentOS-Base.repo && yum makecache && yum -y install epel-release && yum -y install gcc gcc-c++ jq net-tools git unzip && yum clean all && rm -rf /var/cache/yum/* && ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && mkdir -p /opt/android/sdk && mkdir -p /usr/share/jenkins && chmod +x /usr/bin/jenkins-slave#install javaRUN yum -y install /opt/jdk-8u261-linux-x64.rpmENV JAVA_HOME /usr/java/jdk1.8.0_261-amd64ENV JRE_HOME ${JAVA_HOME}/jreENV CLASSPATH .$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jarENV PATH $PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin#install sdk#./sdkmanager –list查看有哪些版本RUN unzip /opt/sdk-tools-linux-3859397.zip -d /opt/android/sdk && mkdir /root/.android/ && touch /root/.android/repositories.cfg && cd /opt/android/sdk/tools/bin && ./sdkmanager –listENV ANDROID_HOME /root/.androidENV PATH $PATH:$ANDROID_HOME:$ANDROID_HOME/emulator:$ANDROID_HOME/platform-toolsENV ANDROID_ROOT /opt/android/sdk ENV PATH $PATH:$ANDROID_ROOT/tools:$ANDROID_ROOT/tools/bin# sdkmanagerSDK指定目录,可以持久化存储# yes | ./sdkmanager –licenses && # yes | ./sdkmanager “build-tools;33.0.0” “platforms;android-33” “build-tools;30.0.2” “platforms;android-30” “platform-tools” –sdk_root=/root/.android#install gradleRUN cd /opt/ && unzip gradle-6.7.1-all.zip && mv gradle-6.7.1 gradleENV PATH $PATH:/opt/gradle/binWORKDIR /optENTRYPOINT [“jenkins-slave”]

三、pipeline 脚本(测试脚本)
