After the domestic Docker source was removed, pulling images in a local network without a proxy became impossible. To set up a CTFD platform that requires images from Docker Hub, a proxy needs to be configured. **Environment:** - An Ubuntu host in the local network needs to pull Docker images (not from the local machine). - Local machine IP: 192.168.10.237. **Setup Instructions:** 1. **Modify `daemon.json`:** - Open the file: `sudo vi /etc/docker/daemon.json`. - Add the following content to use the official image: ```json { "registry-mirrors": [ "https://hub.docker.com/" ] } ``` 2. **Create `proxy.conf`:** - Create the directory and file: ```bash mkdir -p /etc/systemd/system/docker.service.d cd /etc/systemd/system/docker.service.d touch proxy.conf sudo vi proxy.conf ``` - Add the following content: ```ini [Service] Environment="HTTP_PROXY=http://192.168.10.237:7890" Environment="HTTPS_PROXY=http://192.168.10.237:7890" ``` 3. **Restart Docker Service:** - Reload the configuration: ```bash systemctl daemon-reload ``` - Restart Docker: ```bash systemctl restart docker ``` 4. **Check Configuration:** - Verify if the configuration is effective: ```bash systemctl show --property=Environment docker ``` **Alternative Temporary Solutions:** - Use a different registry mirror: ```json { "registry-mirrors": [ "https://docker.1panel.dev" ] } ``` - Pull images using the alternative prefix: ```bash docker pull

After the domestic Docker source was removed, if you want to pull images in the local area network without a proxy, it really can't be done. The self-built CTFD platform needs to pull images from Docker Hub, so you need to set up a proxy.

Environment:

The Ubuntu host in the local area network needs to pull images with Docker, not the local machine
Local machine IP: 192.168.10.237

If it's the local machine pulling images with Docker, just enable the tun mode in Clash.

Clash proxy settings are as follows:

Modify the daemon.json file

sudo vi /etc/docker/daemon.json

Add the following content to use the official image

{
 "registry-mirrors": [
    "https://hub.docker.com/"]
}

Create a proxy.conf file

mkdir -p /etc/systemd/system/docker.service.d
cd /etc/systemd/system/docker.service.d
touch proxy.conf
sudo vi /etc/systemd/system/docker.service.d/proxy.conf

Add the following content:

[Service]
Environment="HTTP_PROXY=http://192.168.10.237:7890"
Environment="HTTPS_PROXY=http://192.168.10.237:7890"

Restart the Docker service

# Load the changed configuration
systemctl daemon-reload
# Restart the Docker service
systemctl restart docker

Check if the configuration takes effect

systemctl show --property=Environment docker

Before setting the proxy

After setting the proxy

other#

{  
  "registry-mirrors": [  
        "https://docker.1panel.dev"
    ]  
}

Or add this address as a prefix when pulling the image

docker pull docker.1panel.dev/yangchuansheng/derper:latest
