drawio 画图工具部署

1、环境介绍
kubernetes版本：v1.23.4
rancher版本：v2.6.3
rancher和kubernetes环境部署参考：
https://blog.csdn.net/zyj81092211/article/details/123068347
drawio版本：v17.4.2
tomcat版本：https://hub.docker.com/_/tomcat

2、软件war包下载
https://github.com/jgraph/drawio

下载不下来可以这里下载

3、将war包上传到NFS服务器

mount -t nfs vdfs01.wtown.com:/Kubernetes/drawio /mnt/

4、部署tomcat 容器
（1）、创建tools命名空间

（2）创建drawio工作负载


容器卷挂载路径/usr/local/tomcat/webapps

5、创建ingress

6、配置代理访问
代理创建参考
