Problem

Docker stacks fail to start with error about missing external networks. The backup_net network (and all other networks) are declared as external: true but never created, causing a chicken-and-egg problem.

Root Cause

Both network/compose.yml and backup/compose.yml declare networks as:

networks:
backup_net:
external: true
name: backup_net

This requires the network to exist before the stack starts, but nothing creates it.

Solution

Changed network declarations from external to bridge driver:

networks:
backup_net:
driver: bridge
name: backup_net

Docker Compose will now automatically create the network when the stack starts.

Affected Networks

ai_net, auth_net, backup_net, cloud_net, coms_net, finance_net, home_auto_net, homepage_net, passman_net, tak_net, vc_net
traefik_backend (already had driver: bridge)

Deployment

cd /opt/data/infra
sudo nixos-rebuild switch --flake .#lazyworkhorse

Verification

docker network ls | grep backup_net
docker ps | grep restic
journalctl -u backup_stack -n 20

- Changed all networks from external: true to driver: bridge
- Fixes chicken-and-egg problem where networks must exist before stacks can start
- backup_net, ai_net, auth_net, cloud_net, coms_net, finance_net, home_auto_net, homepage_net, passman_net, tak_net, vc_net now created automatically
