它使用 privateIP 和 publicIP 创建 sql 实例。那挺好的。但是当我尝试连接到 mysql 时，它会这样说，
来自 gcloud 的命令：
./cloud_sql_proxy -credential_file=mysql-service-account.json -instances=sample:example-mysql-private-fd7795e5=tcp:3306 -ip_address_types=PRIVATE &
mysql -u default -p -h 127.0.0.1 --port=3306 default
问题- 为什么它连接到端口 3307？如何解决这个问题。
couldn't connect to "sample:example-mysql-private-fd7795e5": dial tcp 10.127.0.4:3307: connect: connection timed out.
私有 VPC 网络是否必须进行任何更改才能连接它？
但是没有 Private IP ，它确实可以连接并且可以工作，因为它通过 PublicIP 进行，但是为什么私有 IP 仍然无法连接？
有效的命令：
./cloud_sql_proxy -credential_file=mysql-service-account.json -instances=sample:example-mysql-private-fd7795e5=tcp:3306 &
mysql -u default -p -h 127.0.0.1 --port=3306 default
这是我来自 main.tf 的 VPC 配置：

}

instance_name = var.name_override == null ? format("%s-%s", var.name_prefix, random_id.name.hex) : var.name_override
private_network_name = "private-network-${random_id.name.hex}"

}
请帮忙。
