腾讯轻量云是不能用 k8s,还是我手法的问题？

我发现 ipconfig 轻量云出的是内外 IP

        inet 10.0.16.14  netmask 255.255.252.0  broadcast 10.0.19.255

然后发了工单得到回复

各位彦祖救救我！！

这是不是说轻量云不能玩 k8s 了？？

那 k3s 能玩吗？？？？？

[Judoon]

没看明白，这个 eip 直通什么关系，报错不是 registry.k8s.io 镜像仓库连不上吗？

[zzjcool]

failed to get sandbox image \"registry.k8s.io/pause:3.6\">
你的是不是没有配置镜像加速，及其在国内

[beyondstars]

您好，经分析日志，初步判断：

1. kubelet 拉镜像时需要访问 registry.k8s.io
2. 无法访问 registry.k8s.io
3. 镜像拉取识别，Pod 起不来
4. 导致 kubernetes cluster 起不来

建议：解决如何访问镜像源的问题。

[jakes]

K3s 可以起，我搭的就是 k3s

[johnzr]

1. 你这是源访问不了，换个国内的镜像源。

2. K3S 可以玩，而且它提供了国内的安装方式，可以省个换源的事了。

@Judoon

@beyondstars

感谢确实是访问问题更换源度过了第一关


@jakes
@johnzr

我试了 k3s 一句命令就搞定了真方便，不过还是学习阶段用 k8s 走天龙八部试试
