OpenIM-Docker Deployment Issue: Network Overlap

When deploying OpenIM-Docker using docker-compose, you may encounter the following error:

✘ Network openim-docker_openim-server  Error                           0.0s 
failed to create network openim-docker_openim-server: Error response from daemon: Pool overlaps with other one on this address space

Or there might be issues connecting to the MySQL component.

Diagnosis:

This error occurs because a network gateway on your local machine conflicts with the network that Docker is trying to create.

1. Use the ifconfig command or the ip a command to view the networks being used on your host machine.

Solutions:

1. Removing Duplicate Networks

If there's a duplicate Docker network that's no longer in use:

1. List all Docker networks with:

   docker network ls

2. Identify any networks that are redundant or unused and remove them:

   docker network rm {NETWORK_ID}

3. Refresh the configuration files:

   make init
   # or
   ./scripts/init-config.sh

4. Restart the services:

   docker compose stop;
   docker compose rm;
   docker compose up -d;

2. Addressing System-Level Overlaps

If the problem stems from Docker system configurations (due to Docker updates, uninstallation issues, or overlapping network segments):

1. Set a new network segment using environment variables. For instance, 172.29.0.0/16:

   export DOCKER_BRIDGE_SUBNET=172.29.0.0/16

2. Refresh the configuration files:

   make init
   # or
   ./scripts/init-config.sh

3. Restart the services:

   docker compose up -d

Additional Information:

• Always ensure that your Docker configurations don't conflict with existing network setups.
• Regularly check and clean up redundant or unused Docker networks to maintain a streamlined system.
• When changing Docker network configurations, always document the changes and ensure team members are informed.

This FAQ offers an insight into addressing potential Docker network conflicts that can arise during deployments. Familiarity with Docker commands and understanding of networking basics is key in resolving such issues swiftly.
