當docker拉扯圖像時出現x509錯誤

Question

我創建了一個新的VM並安裝了docker.But但無法拉出任何圖像。 我的VM是Centos7。

就像這樣：

docker pull hello-world 

這是我的錯誤報告，

Error while pulling image: Get https://index.docker.io/v1/repositories/library/hello-world/images: x509: certificate is valid for 192.168.0.81, not index.docker.io 

我不知道什麼是「192.168.0.81」，是和每一個拉命令得到了相同的報告。

請幫助我，謝謝。

如果你使用代理服務器，請確保您配置搬運工人用這個代理工作。 https://docs.docker.com/engine/admin/systemd/#httphttps-proxy
