我目前正在尝试使用HypriotOS版本0.6.1在Raspberry Pi 2上运行docker容器.不幸的是,在我的家庭网络中,我无法从GitHub克隆.

每次都会像时钟一样发生此错误.我将系统连接到新网络,并且工作正常,这表明我的家庭网络有问题.
我怀疑这与使用DNSMasq的路由器本地DNS设置有关,但我并不乐观.以下是我在路由器上的DNSMasq选项:
路由器DNSMasq设置
主机/etc/resolv.conf
@H_404_6@nameserver 127.0.1.1 search home.lan
容器/etc/resolv.conf
@H_404_6@domain home.lan search home.lan nameserver 192.168.11.1
有趣的是,今晚我决定尝试使用–net = host标志运行我的容器,想知道它是否与docker的网桥以及我的网络设置有关.这显然也可以完美地工作!

我曾尝试在路由器上禁用DNSMasq,但这似乎无济于事,所以我想知道是否有人对尝试使Docker的本机桥接模式起作用的想法?
该解决方案由@aaronlehmann在GitHub Issue #1090上发现.此问题(可能仍在)影响AWS实例,但似乎也影响了某些住宅连接.
有两个可能的修复:
>打开conntrack的“自由”标志:echo 1> / proc / sys / net / ipv4 / netfilter / ip_conntrack_tcp_be_liberal.这会导致conntrack / NAT将TCP窗口之外的数据包视为正在跟踪的流的一部分,而不是将其标记为无效并由主机处理.
>添加一条规则以丢弃无效的数据包,而不是允许它们触发RST:iptables -I INPUT -m conntrack –ctstate INVALID -j DROP
对我来说,ip_conntrack_tcp_be_liberal在重启后将永远不会保持其设置.每次我想使用docker时,都需要手动运行上述命令,因此对我来说最好的解决方案是保存
iptables -I INPUT -m conntrack –ctstate无效-j DROP
进入我的iptables.
然后所有问题都消失了!
