# Staging: build backend/frontend images, push to Gitea Container Registry, deploy on self-hosted runner.
#
# Triggers: push to master/main, or manual workflow_dispatch.
# Production (nudentic.ir / git tags): .gitea/workflows/prod-tag-deploy.yml — this file is Windows staging only.
#
# Repository Variables (Settings → Actions → Variables):
#   REGISTRY_HOST        Docker registry host:port (no http/https).
#                        Windows Docker Desktop → host.docker.internal:3000
#                        Do NOT use gitea.wixur.ir unless Windows nginx for that
#                        host has client_max_body_size 0 — Docker layer PUTs 413 otherwise.
#   REGISTRY_OWNER       Gitea user or org that owns the packages
#   PUBLIC_BASE_URL      URL users open in the browser, e.g. http://wixur.ir  (no trailing slash, no :8088)
#   NEXT_PUBLIC_SENTRY_DSN  GlitchTip frontend project DSN (https://…@errors.wixur.ir/…)
#   DEPLOY_SECRETS_DIR   absolute path on runner, e.g. C:/dyolink/secrets
#
# Optional:
#   STAGING_HTTP_PORT    public HTTP port (default 80) — Windows portproxy listens here → 18088
#   STAGING_LOCAL_PORT   Docker bind on 127.0.0.1 (default 18088) — must not equal the public port if portproxy owns it
#   CLONE_HOST           git clone host when runner = Gitea host → 127.0.0.1:3000
#   NODE_IMAGE_SOURCE    extra base-image ref(s), comma-separated, tried before built-in mirrors
#                        e.g. docker.arvancloud.ir/library/node:20-alpine
#
# Same Windows PC runs Gitea + runner + deploy:
#   CLONE_HOST           → 127.0.0.1:3000  (git runs on Windows host)
#   REGISTRY_HOST        → host.docker.internal:3000  (docker commands run inside Docker Desktop VM)
#   Gitea app.ini ROOT_URL → http://host.docker.internal:3000/  (Docker registry auth; browsers use http://wixur.ir:3000)
#   PUBLIC_BASE_URL      → http://wixur.ir  (staging app; Gitea stays on :3000)
#
# Add host.docker.internal:3000 (and wixur.ir:3000 if you pull by public hostname) to Docker Desktop insecure-registries.
#
# Repository Secrets (Settings → Actions → Secrets):
#   REGISTRY_USERNAME    Gitea username for docker login
#   REGISTRY_PASSWORD    Gitea access token (packages:read/write) or account password
#
# Docker on runner: insecure-registries e.g. ["host.docker.internal:3000","wixur.ir:3000"]
#
# Runner: self-hosted with Docker + git. Default shell is powershell (Windows act_runner).
# Windows PowerShell 5.1 does not fail a step when docker/git return non-zero — always check $LASTEXITCODE.
