esh-pfi-infrastructure/playbooks/deploy-task-board.yaml

# Deploy task-board (https://gitea.phasefinal.com/vh/task-board) to a
# Docker host following the PFI /opt/docker/ convention (ana-docker by
# default, but the playbook works against any host with Docker +
# traefik-net in place).
#
# Idempotent: rerunning is safe. Creates-gates + conditional when:
# checks skip work that's already done; `docker compose up -d` is itself
# idempotent (no restart unless compose content or env changed).
#
# Usage:
#   scripts/elway ana-docker --playbook playbooks/deploy-task-board.yaml
#   scripts/elway ana-docker --playbook playbooks/deploy-task-board.yaml --var ref=v0.1.0
#
# Prereqs on the target host:
#   - Docker + docker compose plugin
#   - `traefik-net` docker network (external)
#   - Target user (lkraven) has git SSH access to gitea.phasefinal.com
#     — either SSH key authorized in gitea, or the repo is HTTPS-reachable
#     if you swap `repo_url` below.
#   - Target user is in the `docker` group.
