ps:请提前搭建好nfs环境,nfs中的server为局域网ip
#kubectl create -f nginx-configmap.yaml
ps:
因为使用了NodePort类型,现在你可以在外部通过任意节点服务器ip+端口访问到nginx服务
你可以可以通过pod上的ip来访问到nginx服务

<?php

$host= getenv(‘MYSQL_SERVICE_SERVICE_HOST‘); // 获得环境变量,对应php-service;可以进入pod容器内使用env查看
$dbName=‘test‘;
$user=‘test‘;
$pass=‘1983512gx‘;
$dsn="$dbms:host=$host;dbname=$dbName";
try {
$dbh = new PDO($dsn, $user, $pass);
echo "连接成功<br/>";
$dbh = null;
} catch (PDOException $e) {
die ("Error!: " . $e->getMessage() . "<br/>");
}
Error!: could not find driver
这是因为用到了pdo,但php-fpm2镜像并没有这个扩展
kubectl exec -it php-deployment-3540934081-75sqv -- /usr/local/bin/docker-php-ext-install pdo_mysql
docker restart 4cf7949cfc30
ps:
实际操作中在容器内无法连同service,重启了节点的docker才可以.
在任意节点上或master上访问
#curl http://192.168.2.18:31746/b.php
应该输出连接成功
