[英]Fabric v2.0 in kubernetes (minikube) - error Peer channel join - TLS issue because of pod's names
[英]Errors setting um WeaveNet in Kubernetes with “peer names collision”
我正在设置 Kubernetes-Cluser,但无法正确建立编织网络。
我有 3 个节点:rowlf(主)、rizzo 和 fozzie。 豆荚看起来不错:
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system pod/etcd-rowlf 1/1 Running 0 32m
kube-system pod/kube-apiserver-rowlf 1/1 Running 9 33m
kube-system pod/kube-controller-manager-rowlf 1/1 Running 0 32m
kube-system pod/kube-dns-686d6fb9c-kjdxt 3/3 Running 0 33m
kube-system pod/kube-proxy-6kpr9 1/1 Running 0 9m
kube-system pod/kube-proxy-f7nk5 1/1 Running 0 33m
kube-system pod/kube-proxy-nrbbl 1/1 Running 0 21m
kube-system pod/kube-scheduler-rowlf 1/1 Running 0 32m
kube-system pod/weave-net-4sj4n 2/2 Running 1 21m
kube-system pod/weave-net-kj6q7 2/2 Running 1 9m
kube-system pod/weave-net-nsp22 2/2 Running 0 30m
但是编织状态显示失败:
$ kubectl exec -n kube-system weave-net-nsp22 -c weave -- /home/weave/weave --local status
Version: 2.3.0 (up to date; next check at 2018/06/14 00:30:09)

首先,我不明白为什么连接被标记为失败。 在日志中,我发现了这两行:
INFO: 2018/06/13 17:22:59.170536 ->[172.16.20.12:54077] connection accepted

第二个被误解的事情是“对等名称冲突”错误。 这是正常的吗?
这是来自“rizzo”的日志

我问,因为我现在第四次从头开始重新安装所有东西,每次我在从 traefik 连接到另一台主机上的 pod 时遇到一些麻烦。 我责怪网络,因为这看起来不健康。 你能告诉我到目前为止设置是否正确。 错误是正常的还是我必须关心它们? 最后:我如何请求帮助以及我必须提供哪些信息才能让像您这样的人轻松帮助我摆脱这个令人沮丧的境地?
这是我的版本:

谢谢你。
++++ 更新 ++++ 我像这里提到的那样重置机器 ID: https : //github.com/weaveworks/weave/issues/2767但这会导致我的机器不断重启!
kernel:[ 2257.674153] Internal error: Oops: 80000007 [#1] SMP ARM
最后我在这里找到了解决方案: https : //github.com/weaveworks/weave/issues/3314我们必须禁用fastDP!
我遇到了同样的问题,禁用 fastDP 对我不起作用,但我发现原因是由于我从同一操作系统映像克隆它们,所有节点的/etc/machine-id
值都相同。
我从所有节点中删除了机器 ID,并使用以下命令生成了新的机器 ID:
sudo rm /etc/machine-id
sudo systemd-machine-id-setup
然后重置我的集群
'sudo systemd-machine-id-setup' 为我生成机器 ID 作为旧机器 ID。 我只是编辑机器 ID 并且它可以工作。
