+title: Portainer stack management on vds-kzntsv — canonical pattern

+# Portainer stack management on vds-kzntsv
+
+**Canonical rule:** all docker-compose stacks на VDS управляются через Portainer (`https://portainer.vds.kzntsv.site`). Ad-hoc `docker compose up -d` через ssh — **anti-pattern**, ломает гомогенность ops surface (не видно в UI, нет audit, нет one-click revert).
+
+2026-05-22 retro-migrated 12 ранее ad-hoc стеков (board-viewer, ntfy, registry, verdaccio, gitea, owncloud, postgres, mongo, mariadb, redis, minio-imgproxy, mssql) в Portainer-managed. Skipped `traefik` + `portainer` (management plane — recreate ломает access).
+
+## Portainer API auth
+
+Portainer API token из `vds-kzntsv/full-env` `PORTAINER_API_KEY` ранее давал 401 (см. owncloud-vds-deploy follow-up; требует regen через UI). Workaround — JWT через admin password:
+
+```bash
+JWT=$(curl -ksS -X POST https://portainer.vds.kzntsv.site/api/auth \
+  -H "Content-Type: application/json" \
+  -d '{"username":"vitya","password":"Pryakhin9-VDS-2026"}' | jq -r .jwt)
+```
+
+Pass-store: `pass show vds-kzntsv/full-env` (full env file со всеми creds).
+
+## Migration script (ad-hoc → Portainer-managed)
+
+```bash
+#!/bin/bash
+# /tmp/portainer-migrate.sh — runs on VDS
+set -e
+STACK="$1"          # e.g. "mssql"
+DIR="$2"            # e.g. "/opt/stacks/databases/mssql"
+PORTAINER_URL="https://portainer.vds.kzntsv.site"
+
+JWT=$(curl -ksS -X POST "$PORTAINER_URL/api/auth" -H "Content-Type: application/json" \
+  -d '{"username":"vitya","password":"<from vds-kzntsv/full-env>"}' | jq -r .jwt)
+
+# Transform compose: strip env_file directives (Portainer передаёт env через API array),
+# absolutize ./ paths (Portainer-managed working_dir = /data/compose/<id>/, не stack dir)
+COMPOSE=$(sudo cat "$DIR/docker-compose.yml" | sed \
+  -e '/^\s*env_file:/d' \
+  -e '/^\s*-\s*\.env\s*$/d' \
+  -e "s|\\./|$DIR/|g")
+
+# Parse .env into array
+ENV_ARRAY="[]"
+if sudo test -f "$DIR/.env"; then
+  ENV_ARRAY=$(sudo cat "$DIR/.env" | grep -vE '^\s*(#|$)' | jq -Rs '
+    split("\n") | map(select(length>0) | split("=") | {name: .[0], value: (.[1:] | join("="))})')
+fi
+
+PAYLOAD=$(jq -n --arg name "$STACK" --arg compose "$COMPOSE" --argjson env "$ENV_ARRAY" \
+  '{name:$name, stackFileContent:$compose, env:$env, fromAppTemplate:false}')
+
+# Cleanup existing Portainer stack with same name (idempotency)
+EXISTING_ID=$(curl -ksS -H "Authorization: Bearer $JWT" "$PORTAINER_URL/api/stacks" | \
+  jq -r ".[] | select(.Name==\"$STACK\") | .Id" | head -1)
+[ -n "$EXISTING_ID" ] && curl -ksS -X DELETE "$PORTAINER_URL/api/stacks/$EXISTING_ID?endpointId=1" -H "Authorization: Bearer $JWT" >/dev/null
+
+# Down ad-hoc compose
+sudo docker ps -aq --filter "label=com.docker.compose.project=$STACK" | grep -q . && \
+  (cd "$DIR" && sudo docker compose down 2>&1 | tail -2)
+
+# Create via Portainer
+curl -ksS -X POST "$PORTAINER_URL/api/stacks/create/standalone/string?endpointId=1" \
+  -H "Authorization: Bearer $JWT" -H "Content-Type: application/json" --data "$PAYLOAD"
+```
+
+## Gotchas
+
+1. **`env_file: .env` ломает Portainer string-mode** — Portainer не материализует `.env` файл в `/data/compose/<id>/`. Compose pull fails: `env file /data/compose/<id>/.env not found`. Fix: `sed '/^\s*env_file:/d'` + передавать env через API `env` array.
+2. **Sibling files (`nginx.conf`, certs, scripts) не uploadятся** — string-mode не подхватывает sibling files. `./nginx.conf:/etc/nginx/conf.d/default.conf` Portainer resolves в `/data/compose/<id>/nginx.conf` где файла нет → container mount fails. Fix: абсолютизировать bind через sed `s|\./|$DIR/|g`. Файлы остаются на disk в `/opt/stacks/<stack>/`, Portainer лишь управляет lifecycle.
+3. **registry auth для image pull** — VDS docker должен быть `docker login registry.kzntsv.site` до `docker compose pull`. Иначе `pull access denied`. Login persistent в `/root/.docker/config.json` после первого раза.
+4. **Container recreate downtime** — Portainer up-d убивает существующий контейнер, создаёт новый. Для prod stacks (mssql, owncloud, gitea) ~30-60s простой. Connections retry прозрачно если клиент resilient (IIS reconnects).
+5. **Traefik labels propagate автоматически** — Portainer-managed контейнеры получают те же `traefik.*` labels из compose, traefik docker provider их видит через socket event. Никаких отдельных шагов не нужно.
+6. **`com.docker.compose.project.working_dir`** меняется с `/opt/stacks/<name>` (ad-hoc) на `/data/compose/<id>` (Portainer-managed). Сохранённые `/opt/stacks/<name>/.env` остаются на disk — лишь для backup/reference, не используются compose runtime.
+7. **Volumes preserved across migration** — named volumes (`docker compose down` без `-v`) и binds (`/opt/stacks/<name>/data`) сохраняются. Data layer не теряется при ad-hoc→Portainer переезде.
+8. **Management plane skip** — `traefik` и `portainer` сами через себя нельзя безопасно recreate (теряется access). Оставлены ad-hoc; их docker-compose.yml в `/opt/stacks/{traefik,portainer}/`. Future: bootstrap script для cold-start ставит их first перед всем остальным.

+```
+
+Все 8 IIS prod hosts (emspb / snolla / on.snolla / pilorama98 / labtools.{ru,pro} / tandemmebel / kupimknigi) → 200 через VDS MSSQL после migration.
