摘要

确保主机环回接口允许通信。

例如，如果iptables限制此流量，则以下规则可解决此问题： iptables -A INPUT -s 127.0.0.1 -d 127.0.0.1 -j ACCEPT

容器插件安装使用环回接口上的随机端口。如果无法通信，则安装失败。就我而言，iptables不允许通信。例如，这里的tcpdump输出显示两次尝试失败：

Watching the local interface with tcpdump -i lo`

添加快速规则以允许环回地址上的流量起作用：

iptables -A INPUT -s 127.0.0.1 -d 127.0.0.1 -j ACCEPT

这是在iptables中添加规则并再次尝试插件安装后的tcpdump：

Answer 2

您可以选择使用浏览器手动下载它，然后从下载路径安装它。例如

$ cf install-plugin path/to/ibm-plugin-file

这是IBM插件存储库links的链接。 Haven没试过，让我知道它是否有效:)）

为Cloud Foundry安装IBM容器插件（cf ic）会挂起然后失败
