javascript - CrashLoopBackOff 运行循环：Docker 和 GraphQl 警告不健康连接被拒绝

问题描述

我是 docker 新手，我遇到了这个错误我正在使用 AMZ 平台和 mongoDB 和 graphql 和 Docker 一切工作正常，因为我没有编写所有代码，而且我一直在运行和 CrashLoopBackOff :(我不知道为什么！这就是我得到的：

enter code here
NAME                       READY   STATUS             RESTARTS   AGE
graphql-xxxxxxxxxx-xxxxx   0/1     CrashLoopBackOff   8          12m
graphql-xxxxxxxxxx-xxxxx   0/1     CrashLoopBackOff   7          11m

'kubectl describe pod graphql-xxxxxxxxxx-xxxxx' 的输出：

Warning  Unhealthy  11m (x9 over 12m)      kubelet, pool-g1r6uxpbs-a1jl  Liveness probe failed: Get https://10.244.0.5:4000/healthz: dial tcp 10.244.0.5:4000: connect: connection refused
 Warning  BackOff    3m22s (x24 over 9m3s)  kubelet, pool-g1r6uxpbs-a1jl  Back-off restarting failed container

是的，我仔细检查了我的白名单并添加了我当前的 IP。'kubectl describe logs graphql-xxxxxxxxxx-xxxxxx' 的输出：

{"message":"Starting server with args []...","level":"info"}
{"message":"External IP 167.172.52.238","level":"info"}

请如果有人可以给我一个机会来调试更多这个错误，或者我不知道......

解决方案

该错误getaddrinfo EAI_AGAIN表明您的 docker 环境无法访问互联网。因此，对外部 API 的调用失败。

一个简单的解决方法是创建文件/etc/docker/daemon.json

并插入：

{
    "dns": ["10.0.0.2", "8.8.8.8"]
}

其中 10.0.0.2 是您的机器请求记录的第一个 DNS 服务器，而 8.8.8.8 是备用 DNS 服务器，在这种情况下是 google。
