LXC / Contained (out-of-date)
Description
A LXC container using nested virtualization responsible for running the majority of my services that run as docker containers.
Configuration
Resources
| Hostname | CPU | Memory |
|---|---|---|
| contained | 6 vCPU | 12GB |
Storage
| Mount Point | Source | Destination |
|---|---|---|
| mp0 | /storage/zpool10/downloads | /storage/downloads |
| mp1 | /storage/zpool10/downloads/incomplete | /storage/downloads/incomplete |
| mp2 | /storage/zpool10/media | /storage/media |
| mp3 | /storage/zpool10/services | /storage/services |
| mp4 | /storage/zpool10/services/plex | /storage/services/plex |
| mp5 | /storage/zpool10/services/piwigo | /storage/services/piwigo |
NOTE: mp4 and mp5 are exlpicitly listed because LXC doesn't support recursively mounting any nested mountpoints need to be specified.
Networking
Interfaces
| ID | Name | Bridge | IP Address | Description |
|---|---|---|---|---|
| net0 | eth0 | vmbr3 | 10.0.8.2/21 | DMZ |
| net1 | eth1 | vmbr2 | 192.168.0.2/24 | Private network for VPN |
Docker Networks
A brief overview of how I have my networking setup for Docker.
blackbox_containers
| Gateway | IP/Subnet | IP Range |
|---|---|---|
| 10.0.2.1 | 10.0.4.2/21 | 10.0.4.0/24 |
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_wireguarded
| Gateway | IP/Subnet | IP Range |
|---|---|---|
| 192.168.0.1 | 192.168.0.2/24 | 192.168.0.2/24 |
All containers which should be run through VM / Shield to anonymize their traffic need to be connected to this network. 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 or else public bound traffic will not be routed over this network.
**NOTE** All containers that want to mask the location of their traffic should be party of the a_wireguarded network.
a_host_macvlan (10.0.2.64/27)
| Gateway | IP/Subnet | IP Range |
|---|---|---|
| 10.0.2.1 | 10.0.4.64/27 | 10.0.4.64/27 |
This is a macvlan network that very few containers should need since its purpose is to expose containers to the LAN.
