 # NetBox SLM contributing guidelines
 ## What do I need to know to help?
 If you are looking to help to with a code contribution our project uses, you can find inspiration in the [issue list](https://github.com/ICTU/netbox_slm/issues/).
 Additionally, review the [README](./README.md) document and [NetBox Plugin Development](https://docs.netbox.dev/en/stable/plugins/development/) docs.
 ## How do I make a contribution?
 Never made an open source contribution before? Wondering how contributions work in the in our project? Here's a quick rundown!
 1. Find an issue that you are interested in addressing or a feature that you would like to add.
 2. Fork the repository associated with the issue to your local GitHub organization. This means that you will have a copy of the repository under **your-GitHub-username/repository-name**.
 3. Clone the repository to your local machine using `git clone https://github.com/github-username/repository-name.git`.
 4. Create a new branch for your fix using `git checkout -b branch-name-here`.
 5. Make the appropriate changes for the issue you are trying to address or the feature that you want to add.
 6. Use git `add insert-paths-of-changed-files-here` to add the file contents of the changed files to the "snapshot" git uses to manage the state of the project, also known as the index.
 7. Use `git commit -m "Insert a short message of the changes made here"` to store the contents of the index with a descriptive message.
 8. Push the changes to the remote repository using `git push origin branch-name-here`.
 9. Submit a pull request to the upstream repository.
 10. Title the pull request with a short description of the changes made and the issue or bug number associated with your change. For example, you can title an issue like so "Added more log outputting to resolve #4352".
 11. In the description of the pull request, explain the changes that you made, any issues you think exist with the pull request you made, and any questions you have for the maintainer. It's OK if your pull request is not perfect (no pull request is), the reviewer will be able to help you fix any problems and improve it!
 12. Wait for the pull request to be reviewed by a maintainer.
 13. Make changes to the pull request if the reviewing maintainer recommends them.
 14. Celebrate your success after your pull request is merged!
 ## Where can I go for help?
 If you need help, you can ask questions by [opening a new issue in this repository's issue tracker](https://github.com/ICTU/netbox_slm/issues/new).
 ## What does the Code of Conduct mean for me?
 Our [Code of Conduct](./CODE_OF_CONDUCT.md) means that you are responsible for treating everyone on the project with respect and courtesy regardless of their identity.
 If you are the victim of any inappropriate behavior or comments as described in our Code of Conduct, we are here for you and will do the best to ensure that the abuser is reprimanded appropriately, per our code.

 # Maintenance related tasks
 ## Version upgrade workflow
 1. Update version spec in `netbox_slm/__init__.py` and `sonar-project.properties`
 1. Update NetBox base image versions in `ci/Dockerfile`, `ci/Dockerfile-CI` and `ci/docker-compose.yml`
 1. Ensure that the `PYTHON_VERSION` in the `Dockerfile`s is the same as the NetBox community docker base image
 1. Check for any runtime errors and warnings in the `netbox-*` container logs
 1. Create new version tag on GitHub, following semantic versioning as: `MAJOR.MINOR.PATCH`
 1. Update the `CHANGELOG.md` with new version information and move `[Unreleased]` items to new version section
 1. Build the package: `python -m build`
 1. Upload the distributions to PyPI: `twine upload --skip-existing dist/*`
 ## Developer Guide (local installation)
 *Follow the steps below on your local system to run NetBox and the
 `netbox_slm` plugin in developer mode*
 ### Setup
 The goal below is to run all NetBox components in Docker and run a local
 NetBox Django copy with auto-reload to develop the plugin pointing to
 the PostgreSQL and Redis container instances, basically ignoring the
 NetBox docker runtime server.
 ### Steps
 from your projects directory clone the NetBox repository
 ```shell
 $ git clone https://github.com/netbox-community/netbox
 $ cd netbox
 ```
 install the virtual environment
 ```shell
 $ pipenv shell
 $ pipenv install
 ```
 create and edit `netbox/configuration.py` (based on the template file) add these lines at the end of the file;
 ```python
 DEBUG = True
 SECRET_KEY = 'dummy'
 PLUGINS = [
 'netbox_slm',
 ]
 ```
 The NetBox installation above will be used to run Django management
 commands like `runserver`, `makemigrations` and `migrate`, which will be
 explained in the next steps below;
 from your projects directory clone the `netbox_slm` repository
 ```shell
 $ git clone https://github.com/ICTU/netbox_slm
 $ cd netbox_slm
 $ ./start-netbox.sh
 ```
 This will start NetBox locally (requires Docker) and forward the Redis
 and PostgreSQL ports to the localhost (make sure there’s no processes
 using these ports or change the Dockerfile(s) accordingly)
 Note, you can also start and stop NetBox by hand:
 ```shell
 $ cd netbox-docker
 $ docker compose up -d
 ```
 or stop the stack with
 ```shell
 $ docker compose down
 ```
 #### to start fresh:
 ```shell
 $ docker compose down
 $ docker volume rm netbox-docker_netbox-postgres-data  # et cetera
 $ docker compose up -d --force-recreate
 ```
 this will require you to re-run the migrate commando's for `netbox_slm`, see further down below
 Go back to the NetBox `configuration.py` file and update the PostgreSQL and
 Redis connection strings (username, password) to the ones the NetBox
 Docker backend is using, for example (using default user and passwords
 from the NetBox Docker example):
 ```python
 # PostgreSQL database configuration. See the Django documentation for a complete list of available parameters:
 #   https://docs.djangoproject.com/en/stable/ref/settings/#databases
 DATABASE = {
   'NAME': 'netbox',               # Database name
   'USER': 'netbox',               # PostgreSQL username
   'PASSWORD': 'J5brHrAXFLQSif0K', # PostgreSQL password
   'HOST': 'localhost',            # Database server
   'PORT': '',                     # Database port (leave blank for default)
   'CONN_MAX_AGE': 300,            # Max database connection age
 }
 # Redis database settings. Redis is used for caching and for queuing background tasks such as webhook events. A separate
 # configuration exists for each. Full connection details are required in both sections, and it is strongly recommended
 # to use two separate database IDs.
 REDIS = {
   'tasks': {
       'HOST': 'localhost',
       'PORT': 6379,
       # Comment out `HOST` and `PORT` lines and uncomment the following if using Redis Sentinel
       # 'SENTINELS': [('mysentinel.redis.example.com', 6379)],
       # 'SENTINEL_SERVICE': 'netbox',
       'PASSWORD': 'H733Kdjndks81',
       'DATABASE': 0,
       'SSL': False,
       # Set this to True to skip TLS certificate verification
       # This can expose the connection to attacks, be careful
       # 'INSECURE_SKIP_TLS_VERIFY': False,
   },
   'caching': {
       'HOST': 'localhost',
       'PORT': 6379,
       # Comment out `HOST` and `PORT` lines and uncomment the following if using Redis Sentinel
       # 'SENTINELS': [('mysentinel.redis.example.com', 6379)],
       # 'SENTINEL_SERVICE': 'netbox',
       'PASSWORD': 'H733Kdjndks81',
       'DATABASE': 1,
       'SSL': False,
       # Set this to True to skip TLS certificate verification
       # This can expose the connection to attacks, be careful
       # 'INSECURE_SKIP_TLS_VERIFY': False,
   }
 }
 ```
 Now you can run commands from the NetBox repository like this;
 ```shell
 $ cd netbox/netbox
 $ export PYTHONPATH=../../netbox_slm/netbox_slm/  # or with the pipenv activated run `python3 setup.py develop` from the netbox_slm directory
 $ python3 manage.py migrate netbox_slm
 $ python3 manage.py runserver 8001
 ```

 Port 8000 is taken by the Docker ran variant.

-## Installation Guide
+## Funktionen
-When using the Docker version of NetBox, first follow the `netbox-docker` [quickstart](https://github.com/netbox-community/netbox-docker#quickstart) instructions to clone the `netbox-docker` repository and set up the ``docker-compose.override.yml``.
+- Softwareprodukte und Hersteller verwalten
 - Versionen, Release-Typen und Supportzeiträume erfassen
 - Installationen Geräten, virtuellen Maschinen oder Clustern zuordnen
 - Softwarelizenzen einschließlich Laufzeit, Umfang und Ablageort verwalten
 - Lifetime-Lizenzen oder Erneuerungsintervalle in Tagen, Monaten oder Jahren erfassen
 - Lizenzdateien, Lizenzschlüssel und Links zum Anbieterportal hinterlegen
 - Ablaufwarnungen standardmäßig einen Monat und eine Woche vor Lizenzende
 - Zusätzliche eigene Vorwarnzeit in Tagen, Wochen oder Monaten
 - NetBox-Benachrichtigungen und optionaler E-Mail-Versand über die NetBox-SMTP-Konfiguration
 - Lizenzen Mandantengruppen und Mandanten zuordnen
 - Bedienung über die NetBox-Oberfläche und REST-API
 - Filter, Bulk-Import und Bulk-Bearbeitung
-Note that this plugin is only tested against a single NetBox version at this time, see [Dockerfile-CI](https://github.com/ICTU/netbox_slm/blob/master/ci/Dockerfile-CI).
+> **Hinweis:** Lizenzschlüssel werden in der NetBox-Datenbank und Lizenzdateien im konfigurierten NetBox-
 > Medienverzeichnis gespeichert. Der Zugriff auf Datenbank, REST-API und Medienverzeichnis sollte entsprechend
 > geschützt und gesichert werden.
-Next, follow these instructions (based on the NetBox docker variant [instructions](https://github.com/netbox-community/netbox-docker/wiki/Configuration#custom-configuration-files)) to install the NetBox SLM plugin:
+## Installation
-1. Add ``netbox_slm`` to the ``PLUGINS`` list in
+NetBox installiert lokale Erweiterungen aus `/opt/netbox/local_requirements.txt`. Die Git-URL muss dort dauerhaft
-   ``configuration/plugins.py``.
+eingetragen werden, damit das Plugin bei einem späteren NetBox-Upgrade erneut installiert wird.
 2. Create a ``plugin_requirements.txt`` with ``netbox-slm`` as
   contents.
 3. Create a ``Dockerfile-SLM`` with contents:
-```dockerfile
+### 1. Git-Repository als lokale Anforderung eintragen
 FROM netboxcommunity/netbox:vX.Y.Z
-COPY ../pyproject.toml /tmp/
+```bash
-RUN uv pip install -r /tmp/pyproject.toml
+echo "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git" >> /opt/netbox/local_requirements.txt
 ```
-4. Create a ``docker-compose.override.yml`` with contents:
+Vorher kann geprüft werden, ob der Eintrag bereits vorhanden ist:
-```yaml
+```bash
-version: "3.7"
+grep -qxF "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git" /opt/netbox/local_requirements.txt || \
-services:
+  echo "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git" >> /opt/netbox/local_requirements.txt
  netbox:
    ports:
      - "8000:8080"
    build:
      context: .
      dockerfile: Dockerfile-SLM
    image: netbox:slm
  netbox-worker:
    image: netbox:slm
  netbox-housekeeping:
    image: netbox:slm
 ```
-Now, build the image: ``docker compose build --no-cache``
+### 2. Plugin mit Pip installieren
-And finally, run NetBox with the SLM plugin: ``docker compose up``
+Die Installation muss im Python-Virtual-Environment von NetBox erfolgen:
 ```bash
 /opt/netbox/venv/bin/pip install --upgrade --force-reinstall \
  "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git"
 ```
-## Get in touch
+Alternativ können alle lokalen Anforderungen installiert werden:
-Point of contact for this repository is [Mart Visser](https://github.com/MartVisser), who can be reached by [opening a new issue in this repository's issue tracker](https://github.com/ICTU/netbox_slm/issues/new).
+```bash
 /opt/netbox/venv/bin/pip install -r /opt/netbox/local_requirements.txt
 ```
 Die installierte Version kann anschließend geprüft werden:
 ```bash
 /opt/netbox/venv/bin/pip show netbox-slm
 ```
 Für diese Variante muss dort mindestens Version `1.12.0` stehen.
 ## Ablaufbenachrichtigungen
 Für Lizenzen mit Ablaufdatum sind Benachrichtigungen standardmäßig aktiviert. Die Standardtermine liegen einen
 Monat und eine Woche vor dem Ablaufdatum. Pro Lizenz kann zusätzlich eine eigene Vorwarnzeit festgelegt oder die
 Standardtermine deaktiviert werden.
 Empfänger entscheiden selbst, ob sie informiert werden: Vertrieb, zuständiger Techniker oder andere Benutzer öffnen
 die Lizenz und wählen die NetBox-Aktion **Abonnieren**. Mit **Abonnement beenden** können sie die Meldungen wieder
 abschalten. Ohne Abonnenten wird keine Nachricht versendet.
 Die NetBox-Nachricht wird immer erzeugt. Wird an der Lizenz zusätzlich **E-Mail-Benachrichtigungen** aktiviert, sendet
 das Plugin auch eine E-Mail an die im Benutzerkonto hinterlegte Adresse. Dafür muss der SMTP-Versand in NetBox
 konfiguriert sein.
 Die Aktivierung des E-Mail-Versands darf nur durch Administratoren oder Benutzer mit der Berechtigung
 `netbox_slm.manage_softwarelicense_email_notifications` geändert werden. Die eigentlichen SMTP-Zugangsdaten werden
 ausschließlich in der NetBox-Serverkonfiguration gepflegt und sind im Plugin nicht einsehbar.
 Die Prüfung läuft einmal täglich als NetBox-Systemjob. Sobald der erste konfigurierte Erinnerungstermin erreicht ist,
 werden die Abonnenten bei jedem Joblauf erneut informiert: immer über NetBox und bei aktivierter E-Mail-Option
 zusätzlich per SMTP. Dies wird bis einschließlich des Ablaufdatums wiederholt. Der NetBox-RQ-Worker muss dafür mit
 Scheduler-Unterstützung laufen; dies ist bei der regulären NetBox-Installation mit `rqworker` standardmäßig der Fall.
 ### 3. Plugin in NetBox aktivieren
 In `/opt/netbox/netbox/netbox/configuration.py` ergänzen:
 ```python
 PLUGINS = [
    "netbox_slm",
 ]
 ```
 Falls bereits andere Plugins eingetragen sind, wird `"netbox_slm"` lediglich zur vorhandenen Liste hinzugefügt.
 Eine zusätzliche `PLUGINS_CONFIG`-Konfiguration ist für den Standardbetrieb nicht erforderlich.
 ### 4. Datenbank migrieren und statische Dateien aktualisieren
 ```bash
 cd /opt/netbox/netbox
 /opt/netbox/venv/bin/python manage.py migrate
 /opt/netbox/venv/bin/python manage.py collectstatic --no-input
 ```
 ### 5. NetBox-Dienste neu starten
 Bei einer üblichen systemd-Installation:
 ```bash
 sudo systemctl restart netbox netbox-rq
 ```
 Je nach Installation können die Namen der Dienste abweichen.
 ## Aktualisierung
 ```bash
 /opt/netbox/venv/bin/pip install --upgrade --force-reinstall \
  "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git"
 cd /opt/netbox/netbox
 /opt/netbox/venv/bin/python manage.py migrate
 /opt/netbox/venv/bin/python manage.py collectstatic --no-input
 sudo systemctl restart netbox netbox-rq
 ```
 Der Eintrag in `/opt/netbox/local_requirements.txt` bleibt dabei bestehen.
 ## Deinstallation
 1. `"netbox_slm"` aus der `PLUGINS`-Liste entfernen.
 2. Die Git-Zeile aus `/opt/netbox/local_requirements.txt` entfernen.
 3. Das Python-Paket deinstallieren:
 ```bash
 /opt/netbox/venv/bin/pip uninstall netbox-slm
 ```
 Die Plugin-Tabellen werden dabei nicht automatisch aus der Datenbank gelöscht.
