Description
A LXC container using nested virtualization responsible for running the majority of my services that run as docker containers.

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.
