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
