利用minikube部署k8s集群

1. 部署k8s集群

minikube start

k8s集群部署lnmp

1. 将如下内容存储为lnmp.yaml文件

include fastcgi_params;

}

}

}

2. 执行应用部署

kubectl apply -f lnmp.yaml

3. 验证应用是否正常运行

kubectl get pods -n lnmp
kubectl get svc nginx-php-fpm -n lnmp

4. 测试服务是否正常

#进入Pod
kubectl exec -it $(kubectl get pod -l app=nginx-php-fpm -n lnmp -o jsonpath='{.items[0].metadata.name}') -n lnmp -c nginx -- /bin/bash

#创建info.php文件做测试
echo "<?php phpinfo(); ?>" > /usr/share/nginx/html/info.php

5. 访问服务，验证是否成功
