Question

我使用单独配置创建了一个2组织，每个组织具有2个对等方和1个订购者，以后将更改为筏配置。

kubernetes集群由3个无用的VM组成，具有1个主节点和2个节点工作节点。它们使用法兰绒链接。

我一直在关注此post。直到对等渠道创建部分为止，一切都做得很好。

在链接的帖子中，有些人遇到同样的问题。有些人通过使用IP而不是域名来解决它。我试图放入ip，但是没有用。我该怎么做才能解决此问题？

您可以采取以下措施来对其进行修复：

检查是否满足所有Prerequisites
检查网络的加密材料或生成新的加密材料：cryptogen generate --config=crypto-config.yaml --output=
检查防火墙配置。您可能需要通过以下方式允许适当的端口：firewall-cmd --add-port=xxxx/tcp --permanent
检查您的iptables服务。您可能需要停止它。

请让我知道以上方法是否有帮助。
