docker pull manifest unknown blob errors

问题：docker pull manifest unknown blob errors

原因：公司网络是代理模式，所以我的 docker 服务配置成proxy模式：

 1 [root@localhost ~]# cat /usr/lib/systemd/system/docker.service
 2 [Unit]
 3 Description=Docker Application Container Engine
 4 Documentation=https://docs.docker.com
 5 After=network.target firewalld.service
 6 
 7 [Service]
 8 Type=notify
 9 Environment="http_proxy=http://192.168.59.241:8888/" "https_proxy=https://192.168.59.241:8888/"
10 ExecStart=/usr/bin/dockerd --insecure-registry 172.19.15.95:4000
11 ExecReload=/bin/kill -s HUP $MAINPID
12 LimitNOFILE=infinity
13 LimitNPROC=infinity
14 LimitCORE=infinity
15 TimeoutStartSec=0
16 Delegate=yes
17 KillMode=process
18 
19 [Install]
20 WantedBy=multi-user.target

把配置文件中的 代理去掉：

Environment="http_proxy=http://192.168.59.241:8888/" "https_proxy=https://192.168.59.241:8888/"
