启动顺序与初始化容器
我们可以使用初始化容器(Init Container)来控制启动顺序。 ● Pod中的初始化容器在应用容器之前启动。 ● 初始化容器未执行完成应用容器不会启动。 ● 多个初始化容器按顺序执行前一个执行完成才会执行下一个。

Ingress入口 ingress作用
功能类似一个Nginx服务器。
URL路由规则配置实现负载均衡、流量分割、流量限制https配置基于名字的虚拟托管
创建Ingress资源需要先部署Ingress控制器如ingress-nginx。 不同控制器用法和配置是不一样的。 k3s自带一个基于Traefik的ingress控制器因此我们可以直接创建ingress资源无需再安装ingress控制器。 注意ingress只能公开http和https类型的服务到互联网。公开其他类型的服务需要NodePort或LoadBalancer类型的Service。 ingress部署

ingress路径类型
Ingress 中的每个路径必须设置路径类型(Path Type),当前支持的路径类型有三种 Exact精确匹配 URL 路径。区分大小写。 PrefixURL 路径前缀匹配。区分大小写。并且对路径中的元素逐个完成。 (说明/foo/bar 匹配 /foo/bar/baz, 但不匹配 /foo/barbaz。) ImplementationSpecific对于这种路径类型匹配方法取决于 IngressClass定义的处理逻辑。
