Question

我的目标是使集群在树莓派4b上运行。目前，我正在尝试/测试/在流浪汉中玩kubernetes。我的项目在这里： https://github.com/kentahikaru/vagranttraining/tree/master/kubernetes_testing

我能够初始化master并将节点连接到集群。

但是我在部署boinc客户端时遇到了麻烦，我想要这样。我正在使用的部署在这里： https://github.com/kentahikaru/vagranttraining/blob/master/kubernetes_testing/Testing/boinc/boinc_client_deploy.yaml 它在github上的上传方式，正在运行。我可以部署它，它将切换到“运行”状态。但是，当我取消注释“ command”和“ args”（因为我希望它自动连接到我的帐户）时，它将崩溃并且我不知道为什么：

vagrant@master:~$ kubectl get pods -o wide
NAME                           READY   STATUS             RESTARTS   AGE   IP            NODE    NOMINATED NODE   READINESS GATES
boincclient-69cdf887dc-7phr2   0/1     CrashLoopBackOff   1          12s   10.244.2.69   node2   <none>           <none>

从docker登录节点（/ var / log / containers）：

{"log":"can't connect to local host\n","stream":"stderr","time":"2020-11-11T22:27:35.708789661Z"}
{"log":"can't connect to local host\n","stream":"stderr","time":"2020-11-11T22:27:35.711018367Z"}
{"log":"can't connect to local host\n","stream":"stderr","time":"2020-11-11T22:27:35.714129251Z"}
{"log":"can't connect to local host\n","stream":"stderr","time":"2020-11-11T22:27:35.714160084Z"}

我也无法弄清楚“ kubectl日志”为什么不起作用：

感谢您的帮助。

所以解决方案是从dockerfile调用入口点命令。

在Kubernetes集群中运行Boinc客户端
