Previous solution only worked until I reboot my machine. Sigh.
But I’ve found another trick in my linux.
I did force the daemon to run through a proxy before connecting the the docker servers, as the registry-1.docker.io was giving me timeout error and I could not even ping it anymore.
Following this instructions 87 I could fix my problem. And that’s all I did:
1. Create a new directory:
$ sudo mkdir -p /etc/systemd/system/docker.service.d
2. Get a free http proxy from this list 195.
3. Create the file below and paste the http proxy server
# File: /etc/systemd/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=208.123.76.34:8080"
Environment="NO_PROXY=localhost,127.0.0.1"
4. Reload systemd manager configurations:
sudo systemd daemon-reload
5. Restart the Docker’s daemon service:
sudo systemd restart docker
6. Check if it’s working:
docker pull alpine
Now it is working here, but the download speed is slow as it is not connected directly to the server. I googled a lot and I’ve no clue how to fix this another way.
.Edit: Don’t use a proxy to log in as the connection goes through someone’s pc, they will receive your credentials. Today I removed the http proxy to login, and sometimes the connection is stablished, sometimes it isn’t. My network is slow since the past week. Perhaps that’s the reason?
之前的解决方案只能在重新启动计算机之前起作用。叹。
但是我在我的电脑中找到了另外一个窍门linux。
我确实强迫守护程序在连接Docker服务器之前通过代理运行，因为这registry-1.docker.io给了我超时错误，我什至无法对其进行ping操作。
按照此说明87， 我可以解决我的问题。这就是我所做的一切：
1.创建一个新目录：
$ sudo mkdir -p /etc/systemd/system/docker.service.d
2.从此列表195 获得免费的http代理。
3.在下面创建文件并粘贴http代理服务器
# File: /etc/systemd/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=208.123.76.34:8080"
Environment="NO_PROXY=localhost,127.0.0.1"
4.重新加载systemd Manager配置：
sudo systemd daemon-reload
5.重新启动Docker的守护程序服务：
sudo systemd restart docker
6.检查它是否正常工作：
docker pull alpine
现在它可以在这里工作，但是下载速度很慢，因为它没有直接连接到服务器。我在Google上搜索了很多，但不知道如何以其他方式解决这个问题。
。Edit:当连接通过某人的PC时，请勿使用代理进行登录，否则他们会收到您的凭据。今天，我删除了HTTP代理进行登录，有时建立了连接，有时没有建立连接。自上周以来，我的网络运行缓慢。也许那是原因吗？
