Networking

Interfaces

Docker Networks

A brief overview of how I have my networking setup for Docker.

blackbox_containers

Type Gateway IP/Subnet IP Range
bridge - - -

Traefik binds to the host ports on LXC / Contained for HTTP(S) traffic that has been forwarded from firewall and proxies it to the appropriate container using this bridge network.

  • Containers that are part of this network can directly access other containers in this network using their hostnames and/or container names.
  • Using hostnames to network containers provides an IP agnostic way to communicate while reducing overhead of SSL.
  • Containers in this network are not publically accessible, access is controlled with Traefik acting as a gatekeeper.

**NOTE** All publically accessible containers should be part of the blackbox_containers network.

a_transport

Type Gateway IP/Subnet IP Range
macvlan 10.0.9.1 10.0.9.2/24 10.0.9.128/25

All containers which need anonimity should be connected to this network so their traffic is automatically routed through a VPN. It is prefixed with a_ because networks are added to containers alphabetically and this must be added first to be assigned as the default gateway.

**NOTE** All containers that want to mask the location of their traffic should be part of the a_transport network.
