View Container Networks

To see what network(s) your container is connected to:

docker inspect container_name -f "{{json .NetworkSettings.Networks }}"

Disconnect from Network

To disconnect your container from a network:

docker network disconnect test-net container_name

Connect to New Network

To connect your container to another network:

docker network connect test-net-2 container_name

Additional Network Commands

# List all networks
docker network ls

# Create a new network
docker network create test-net-2

# Inspect network details
docker network inspect test-net-2

# Remove a network
docker network rm test-net

Best Practices

• Always verify network connections before disconnecting
• Use meaningful network names
• Document network configurations
• Monitor container connectivity
• Use custom networks instead of default bridge

Common Use Cases

• Migrating containers between networks
• Isolating container groups
• Setting up multi-tier applications
• Testing network configurations
• Troubleshooting connectivity issues
