openrestry中的hello world

news2024/11/19 10:38:50

概述

此篇将在 k8s 运行起一个 openrestry
环境：k8s：1.27.9 ，openrestry(docker镜像版本)： 1.25.x ，k8s 与 ingress 请参考我的其它文章
离线镜像包请参考：openrestry-1.25.x离线镜像安装包

实践

部署openrestry

[root@hadoop02 ~]# cd openregisty/
[root@hadoop02 openregisty]# ls
ingress-all.yaml  openregisty-dp-svc.yaml  openregisty-dp.yaml
[root@hadoop02 openregisty]# kubectl create -f  openregisty-dp.yaml
persistentvolumeclaim/openresty-nfs created
deployment.apps/openresty created
[root@hadoop02 openregisty]# kubectl create  -f openregisty-dp-svc.yaml
service/openresty-svc created
[root@hadoop02 openregisty]# kubectl create -f ingress-all.yaml
Error from server (AlreadyExists): error when creating "ingress-all.yaml": ingresses.networking.k8s.io "ingress-nacos" already exists
[root@hadoop02 openregisty]# kubectl create -f ingress-all.yaml
ingress.networking.k8s.io/ingress-all created
