# --- General ----------------------------------------------------------------
host_timezone: "Europe/Brussels"

# --- ZFS --------------------------------------------------------------------
# The pool can be backed three ways:
#   file   - a loopback disk image (NO spare disk needed). Real ZFS features,
#            backed by a file on the OS disk. Ideal for a cheap test VM.
#   single - one whole spare disk/partition.
#   mirror - two disks/partitions (redundant); use for production.
# Disk modes are DESTRUCTIVE to every listed device and refuse a non-empty
# device unless zfs_pool_force: true. File mode wipes nothing.
zfs_pool_name: tank
zfs_pool_mode: file            # file | single | mirror

# file mode:
zfs_pool_file_path: /var/lib/heleos/tank.img
zfs_pool_file_size: "30G"      # sparse; grows as data is written

# single / mirror modes (prefer stable /dev/disk/by-id/... paths in production):
zfs_pool_disks:
  - /dev/sdb

zfs_pool_force: false
zfs_compression: lz4          # lz4 (fast) or zstd (denser)

# Datasets created under the pool. Web roots and per-site/customer datasets are
# created later by the provisioning CLI (Phase 4); here we create the fixed
# platform datasets + the customers parent. See docs/03-naming-conventions.md.
zfs_child_datasets:

# --- Docker -----------------------------------------------------------------
# APT codename for Docker's repo. Defaults to the VM's release. Docker only
# publishes repos for LTS + recent codenames — on a non-LTS Ubuntu (e.g.
# oracular/plucky) set this to the nearest LTS, e.g. "noble".
docker_apt_codename: "noble"
# Native ZFS storage driver keeps image layers as ZFS datasets under the pool
# (data-root sits on tank/platform/docker). Switch to overlay2 only if you have
# a specific reason.

docker_data_root: /var/lib/docker
# Address pool for the many per-site bridge networks (avoids subnet exhaustion).

# --- Firewall (nftables + Docker egress) ------------------------------------
ssh_port: 22
firewall_allowed_tcp_ports: [80, 443]   # SSH is added automatically via ssh_port
# Outbound SMTP from containers is blocked (spam prevention from hacked sites).
smtp_blocked_ports: [25, 465, 587]
smtp_relay_host: ""                      # optional: allow SMTP only to this host

# --- SSH hardening ----------------------------------------------------------
# ⚠️  If ssh_disable_password_auth is true you MUST provide admin_authorized_keys
#     for admin_user, or you will lock yourself out. The playbook asserts this.
admin_user: "{{ ansible_user }}"
admin_authorized_keys: []                # list of public key strings
ssh_disable_password_auth: false         # flip to true once key login is verified
