How to change the Default Docker Subnet

 

If the Docker Engine default bridge network is conflicting with your internal network hosts access, you can change the default Docker subnet by following these steps:

1. First, you need to delete the containers 
   

   sudo docker rm -f $(docker ps -a -q)

   sudo systemctl stop docker

2. Next, change the subnet IP inside "/etc/docker/daemon.json", by using this command:
   

   sudo vim /etc/docker/daemon.json

3. Type in the Netmask IP. With the following structure. Please keep in mind that the IP used here is an example:
   

   {
    "default-address-pools":
    [
    {"base":"10.10.0.0/16","size":24}
    ]
   }

4. Restart the Docker Daemon by using this command:
   

   sudo service docker restart
