Configuring a Proxy for Logging In to the Ascend Hub

root@ubuntu:~# docker login -u xxx -p xxx ascendhub.huawei.com
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get http://ascendhub.huawei.com/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

The possible cause is that the proxy is not configured. To configure the proxy, perform the following steps:

1. Run the following commands to create proxy configuration file proxy.conf for Docker:

   mkdir -p /etc/systemd/system/docker.service.d
   vim /etc/systemd/system/docker.service.d/proxy.conf

2. Add the following information to the proxy.conf file, set the proxy address as required, save the file, and exit.

   [Service]
   Environment="HTTP_PROXY=http://xxxx.xxx.xxxx.xxxx"
   Environment="HTTPS_PROXY=http://xxxx.xxx.xxxx.xxxx"

3. Run the following command to open the daemon.json file and configure insecure-registries for Docker:

   vim /etc/docker/daemon.json

   • If the insecure-registries field exists in the file, add the following content to the field:

     ascendhub.huawei.com

     Example:

     {
        
          "insecure-registries": ["xxxxxxxxxxxxxxxx",
                                  "ascendhub.huawei.com"],
     
     }

   • If the file does not contain the insecure-registries field, add this field.

     Example:

     {
     
        "exec-opts": ["native.cgroupdriver=systemd"], # Assume that this line is the last line of the original /etc/docker/daemon.json file. After adding the insecure-registries field, you need to add a comma (,) after the square bracket (]) in this line.
     
        "insecure-registries": ["ascendhub.huawei.com"]
     
     }

4. Restart the Docker service.

   systemctl daemon-reload;
   systemctl restart docker;
