caas-agamaha: 最外层负载，负载前端hcenter和后端caas-haproxy
caas-hcenter：前端程序，处理用户请求
caas-haproxy：后端haproxy，负载后端caas-muddle，NFS，OpenShift和caas-omp
caas-muddle：后端java程序，主要提供用户容器相关操作接口
caas-omp：后端java程序，主要提供用户相关管理的接口
caas-redis： 数据缓存
MySQL：数据持久化存储
除MySQL外，其他组件均为容器部署，容器环境变量信息如下

服务无法正常访问
排查步骤
- 检查客户端网络连接是否正常
- 域名解析是否正确
- 检查caas-agamaha：环境变量是否正确，caas-agamaha是否能跟caas-hcenter和caas-haproxy正常通信
- 检查caas-hcenter是否启动正常，环境变量是否正确，能否跟caas-haproxy正常通信
- 检查caas-haproxy是否启动正常，环境变量是否正确，能否跟caas-muddle，NFS，OpenShift和caas-omp服务器正常通信
- 检查caas-muddle是否启动正常，环境变量是否正确，查看日志中是否有报错
- 检查caas-omp是否启动正常，环境变量是否正确，查看日志中是否正常
- 检查caas-redis是否启动正常
- 检查mysql是否正常提供服务
用已创建命名空间的用户登录仍然提示输入命名空间 排查步骤
- 检查caas-haproxy中关于caas-muddle的环境变量是否设置正确
- 检查caas-muddle是否能正常提供服务
