搭建harbor時，docker login報錯 https on 8.8.8.8:53: no such host
網上也有類似錯誤，原因卻不同，分享一下，給同樣問題的人一個提示
我的域名是https://hub.fc.com，錯誤信息如下：
[root@harbor harbor]# docker login https://hub.fc.com
Username: admin
Password:
Error response from daemon: Get https://hub.fc.com/v2/: Get https://https//hub.fc.com/service/token?account=admin&client_id=docker&offline_token=true&service=harbor-registry: dial tcp: lookup https on 8.8.8.8:53: no such host
錯誤原因，此處多了https://
cd /usr/local/harbor
vi harbor.cfg
# 錯誤內容如下
hostname = https://hub.fc.com
圖片展示
問題處理 -----harbor目錄下操作
# 刪除 https//
hostname = hub.fc.com
# 停止容器並刪除全部鏡像，我這裏只有harbor相關容器鏡像，慎用
docker-compose down
# 重載生效
./prepare
# 開啓所有容器
docker-compose up -d
# 登錄成功
[root@harbor harbor]# docker login https://hub.fc.com
Username: admin
