base.yaml
template/base.yaml 定义 namespace、控制面权限、运行时超时、镜像默认值、挂载文件根目录、数据源模式和导入目录。
启动大禹系统前请检查其中与部署环境相关的值。
下面概述运行时相关字段；镜像坐标以当前检出的 template/base.yaml 为准。

current-tag 表示当前检出代码构建的镜像集合。构建镜像和配置 default-image-meta 时应使用同一个值。
最需要按部署调整的是 namespace、default-image-meta、default-file-mount-prefix 与 datasource。
除非同一集群中的另一个大禹系统 namespace 有意使用不同名称，否则请保留默认 RBAC 名称。运行时 worker 不需要 Kubernetes 凭据。
Redis AOF 保存在云端节点的 default-file-mount-prefix/runtime-state/<namespace>/redis 下，应确保该路径可写且持久。
模型与数据源文件见部署挂载文件。
