尝试运行基本 ubuntu 图像时出现关键错误

Question

我正在尝试运行基本图像，如 Docker 教程中所述：-

docker --version
Docker version 1.9.0, build 76d6bc9

docker run -t -i ubuntu:14.04 /bin/bash

但它正在报告：

Error while pulling image: Get https://index.docker.io/v1/repositories/library/ubuntu/images: x509: certificate is valid for FG3K6C3A15800002, not index.docker.io

我在公司防火墙后面，所以适当地设置了 http_proxy 和 https_proxy env 变量。服务器本身是 Ubuntu 14.04 LTS。

我已经阅读了各种关于时钟设置等的帖子，但这些看起来还不错。

有人有什么想法吗？

即使您声明已设置代理变量，请确保在您的 /etc/default/docker:

中尝试此完整代理变量集

export "HTTP_PROXY=http://<user>:<password>@<proxy.company.com>:<port>"
export "HTTPS_PROXY=http://<user>:<password>@<proxy.company.com>:<port>"
export "http_proxy=http://<user>:<password>@<proxy.company.com>:<port>"
export "https_proxy=http://<user>:<password>@<proxy.company.com>:<port>"
export "NO_PROXY=.company.com,.sock,localhost,127.0.0.1,::1"
export "no_proxy=.company.com,.sock,localhost,127.0.0.1,::1"

如果这不能解决问题，请将 docker 升级到最新的 1.10.1。

注意：docker machine issue 531 提到 docker-machine provision 作为解决方法。

更新2021 on issue 531

I had the same exact issue just now and apparently it was fixed by resetting docker to factory settings and enabling the Kubernetes cluster again.

EDIT: I managed to reproduce the fix on a second machine. The exact steps in my case were:

start Docker Desktop

update to 3.2.1 -> immediately after this another updated was available to 3.2.2

update to 3.2.2

enable Kubernetes cluster -> wait until the error appears

right click on Docker in the System Tray -> choose Troubleshoot

click Reset to factory defaults -> wait until the reset is finished

right click on Docker in the System Tray -> choose Quit Docker Desktop

open Docker Desktop again

select only Enable Kubernetes
