# Base build for nh3-albok (VM 110 on nh3-pve-2, 10.100.50.44): the dedicated albok-service host.
#   scripts/elway infra-ops@10.100.50.44 --playbook playbooks/nh3-albok-host.yaml
# Order: playbooks/nh3-albok-vm.yaml (on nh3-pve-2) → bootstrap-infra-ops-user.yaml run AS vh → this
# → albok-service-host.yaml (ids + /srv/albok) → stacks/albok-service/README.md deploy steps.
#
# Built to docs/pfi/fleet-conventions.md: `vh` 1000 (cloud-init), `infra-ops` 850, `docker` gid 851
# created BEFORE docker-ce so the package adopts it, /opt/docker root:docker 2775.
#
# ⚠ This host exists to keep root-over-docker away from the albok store. So, unlike the general docker
#   hosts, it gets NO portainer/dockge/agent containers, NO socket mounts, and dockerd does NOT listen on
#   tcp/2375 (Homepage cannot discover it; the Homepage entry for albok is static in services.yaml).
#   Do not add any of those here. A host-level read of containers is `ssh` + `docker ps`.
