Setting

1 Configuration

  • Supports viewing the Docker running status and performing operations such as restarting the service
  • The default configuration file path is: /etc/docker/daemon.json

  • Image Acceleration: If application installation fails or image pulling times out, you can configure image accelerators to optimize the process
    • Acceleration address to configure: 
      https://docker.1panel.live

After configuring the above acceleration address, if pulling application images still fails, further discussion is available on the forum

  • Private Registry: Self-built private image registries such as Harbor, Nexus, docker-registry, etc.
  • iptables: This setting disables Docker's automatic configuration of iptables rules, which may cause containers to fail to communicate with external networks
  • live-restore: Whether to stop all containers when the Docker service is stopped
  • cgroup-driver: The default Cgroup Driver used is cgroupfs

2 Using IPv6

  • Ensure your device is assigned an IPv6 address. Check the current device's IPv6 with the command ip addr show. If the output for the physical network card contains a line with inet6 and scope global, the network card supports IPv6: 
    eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:16:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    inet 172.31.168.107/20 brd 172.31.175.255 scope global dynamic eth0
        valid_lft 314955046sec preferred_lft 314955046sec
    inet6 2xxx:xxxx:xxxxx:xxxx:xxxx:xxxx:xxxx:xxxx/64 scope global dynamic 
        valid_lft 113120sec preferred_lft 69920sec
    inet6 fe80::xxxx:xxxx:xxxx:xxxx/64 scope link 
        valid_lft forever preferred_lft forever
  • Enable IPv6 in the panel settings, where fixed-cidr-v6 is the subnet of the IPv6 network segment obtained in the previous step (configures the default network, with a maximum prefix length of /80)

  • Check if it takes effect through [Networks] - [Details]. If effective, the value of EnableIPv6 is true, and IPAM.Config[1].Subnet is the fixed-cidr-v6 configured in the previous step

  • Create an IPv6 network

  • Create containers using the IPv6 network you created
