json - Kubernetes:拉取镜像失败。服务器向 HTTPS 客户端提供 HTTP 响应

Question

我正在尝试使用 Kubernetes与 Docker .我的图像与 Docker 一起运行。我有一个主节点和两个工作节点。我还创建了一个这样的本地注册表 $ docker run -d -p 5000:5000 --restart=always --name registry registry:2并将我的形象插入其中。到目前为止一切正常。

我加了 { "insecure-registries":["xxx.xxx.xxx.xxx:5000"] }到 daemon.json文件位于 /etc/docker .而且我还改变了docker-file的内容在 /etc/default/至 DOCKER_OPTS="--config-file=/etc/docker/daemon.json" .我在所有节点上进行了更改，然后我重新启动了 docker 守护进程。

我可以使用以下命令从每个节点提取我的图像:
sudo docker pull xxx.xxx.xxx.xxx:5000/helloworldimage
我尝试使用以下命令从主节点创建我的容器:
sudo kubectl run test --image xxx.xxx.xxx.xxx:5000/helloworldimage
比我收到以下错误:

Answer 1

Kubernetes: Failed to pull image. Server gave HTTP response to HTTPS client.

{ "insecure-registries":["xxx.xxx.xxx.xxx:5000"] }

到 daemon.json文件位于 /etc/docker .
我通过在 上配置它解决了这个问题所有 kubernetes 节点 .
