Ubuntu 22.04 Kubernetes 设置-无法拉取镜像

我正在尝试在我的实验室环境中安装 Kubernetes 测试。我使用为 curl、apt 和 wget 配置的代理，但 forcepoint 使用了一个特殊证书。所有 ssl 连接都将通过 forcepoint 证书传递。我已经将此 forcepoint 证书安装到根 ca。

我尝试按照说明安装 kubernetes https://phoenixnap.com/kb/install-kubernetes-on-ubuntu

我在第 10 步就卡住了。

  1. 最后，通过键入以下内容初始化集群sudo kubeadm init --control-plane-endpoint=master-node --upload-certs

这里我遇到了 ImagePull 的连接问题。

为了更详细地说明这一点，我尝试在其余图像之前拉取图像，但sudo kubeadm pull image收到以下错误消息：

如果我尝试访问https://dl.k8s.io/release/stable-1.txt通过 wget 一切正常。

您知道问题可能出在哪里吗？

答案1

您可能缺少 kubeadm 的代理设置，我会尝试在 bash 中设置代理：

export HTTP_PROXY=http://proxy.example.com:port
export HTTPS_PROXY=http://proxy.example.com:port
export NO_PROXY=localhost,127.0.0.1,.example.com

您可能需要重新启动 containerd 服务

 systemctl restart containerd.service
