Network

Docker networks are used for communication between containers. Through the network management page, you can create, view, and delete networks.

Network List

Go to Container > Network tab to view the network list.

The list displays the following information:

• Name: Network name
• Driver: Network driver type
• Scope: Network scope
• Subnet: Network subnet address
• Gateway: Network gateway address
• Created Time: Creation time
• Actions: Delete

Default Networks

Docker automatically creates the following networks after installation:

Network Name	Driver	Description
bridge	bridge	Default network, containers access external network through NAT
host	host	Container directly uses host network, no network isolation
none	null	No network, container is completely isolated

AcePanel also creates the acepanel-network network for containers deployed by panel compose templates. Please do not delete it.

Create Network

1. Click the Create Network button
2. Enter network name
3. Select network driver
4. Configure subnet and gateway (optional)
5. Click Create

Network Drivers

• bridge: Bridge network, the most commonly used network type. Containers connect through a virtual bridge and can communicate with each other.
• host: Host network, container directly uses the host's network stack, best performance but no isolation.
• overlay: Overlay network, used for cross-host container communication (Swarm mode).
• macvlan: MAC VLAN network, assigns independent MAC addresses to containers.

Network Usage

Specify Network When Creating Container

When creating a container, select the network to use in the Network option.

Communication Between Containers

Containers in the same network can access each other by container name.

For example, in the acepanel-network network:

• Container A is named web
• Container B is named db
• Container A can access Container B's database through db:3306

Delete Network

Select a network and click the Delete button to delete the network.

Note

• Default networks (bridge, host, none) and acepanel-network cannot be deleted
• If there are containers in the network, you need to delete or disconnect the containers before deleting the network

Clean Networks

Click Clean Networks to delete all unused custom networks.
