在 localhost 上安装 Ubuntu Kubernates 1.20 -> 文档导致错误 -> 等待 3 个 kube-system pod 启动

  • 772

我在 VirtualBox 上创建了全新的 Ubuntu 20.03，而不是使用文档开始安装。机器有 Quadro RTX 卡（可能会影响？）。

文档很混乱，因为有很多方法可以做——我检查了几乎所有方法，结果非常糟糕，因为它从未导致成功。你能帮忙安装吗，或者 Ubuntu Kubernetes 不能工作，这是浪费时间？

是否需要额外的日志？

导致此错误的无效文档：

  1. https://ubuntu.com/kubernetes/install#multi-node
  2. https://ubuntu.com/kubernetes/docs/install-manual
  3. https://ubuntu.com/kubernetes/docs/install-local

首先我尝试：

sudo snap install lxd

sudo lxd init
# all default apart:
# dir
# ipv6 none

sudo snap install juju --classic
juju bootstrap localhost

juju add-model k8s
juju deploy charmed-kubernetes

结果是 10 台机器而不是工作主机 :)

与文档中的其他排序相同，都一无所获。也许我做错了什么，也许 Ubuntu Kubernetes 不能在 localhost 上运行。

juju add-model k8s-production
juju deploy cs:bundle/charmed-kubernetes-596

即使是这种小型部署也不起作用（安装永远不会结束）。

juju add-model k8s-development
juju deploy cs:bundle/kubernetes-core-1200
juju

    我看起来这是解决方法：

    juju config kubernetes-worker kubelet-extra-config='{protectKernelDefaults: false}'
