Cloudron Forum

Hi,
I love the simplicity of Meemo and I am using it extensively, but the shortcomings, primarily MD rendering (checkboxes, strike-through), do limit its usage for me.
Looking for an alternative I stumbled un Memos: https://www.usememos.com/
It seems to be very similar in its approach, and it looks as if it does not suffer from the same limitations.
Could it be an alternative or even a replacement?

@klawitterb Oh I see, good point, that part escaped my notice. Mediafiles are directly served by nginx and only the rest is forwarded to Gunicorn.

    #serve media files
    location /media/ {
      alias /app/data/mediafiles/;
    }
    
    # pass requests for dynamic content to gunicorn
    location / {
      proxy_set_header Host $http_host;
      proxy_pass http://localhost:8080; # -> this gos to Gunicorn
    }

So with the Cloudron Nginx, static files would still be served from Gunicorn. SO I guess, it is worth the effort
Thanks for that.

@klawitterb Very cool indeed, thanks for the link. Works like a charm.

I myself got passed the SQL ENV variables and had Tandoor up and running but I was then running into the problem of the static file generation at boot time start.sh. I did not manage to get it out of start.sh and into the Dockerfile, like you did here:

RUN venv/bin/python3 manage.py collectstatic_js_reverse
RUN venv/bin/python3 manage.py collectstatic --noinput

Anyway, dunno if it makes sens to continue this thread on discussing building Tandoor Recipes but I have one question. In your setup you still use nginx in the image. I think you followed the manual installation description where everything including Postgres and Nginx is put on the same host.
But we do have an reverse proxy in Cloudron already. So I .dockerignoredd your nginx.conffiles and had port 8080 (gunicorn) instead of 8000 (nginx) directly exposed.

Do you see a special reason for having another nginx in the image?

@nebulon, yes, I did go through all the documentation I could find and I tried a lot of different stuff to get the upstream image to work. Doing so, it dawned on me, that it might not be as easy as I thought

Anyway, this image exposes an HTTP port and looking at their docker compose file, it only depends on a Postgres DB. The Postgres configuration is passed as environment variables into the image.

The Cloudron Postgres addon creates and fills environment variables. Is it possible to rename them to reflect the names required by the image? Maybe as part of the CloudronManifest?

But I guess you are right, when it comes to stuff like local storage etc, I might end up having to go the manual installation path anyway. Still I think, an image that is completely self-contained, only exposing an HTTP port, why would I want to re-build that image for Cloudron?

Could you maybe elaborate a bit on e.g, what does cloudron builddo on top of docker build, if that makes sense?

Anyway, I will have a look into the manual installation path and see where I can get.

I tried to package my first Cloudron app but I am failing.

The application Tandoor Recipes is an already pre-built Docker image. It depends on a Postgres DB and from it's overall architecture I think it is a perfect candidate for Cloudron.

I think all that needs to be done is to pass the Postgres ENV variables Cloudron provides into the container. The Tandoor documentation states to simply start the image, one should pass theses parameters to docker run:

docker run -d \
    -v ./staticfiles:/opt/recipes/staticfiles \
    -v ./mediafiles:/opt/recipes/mediafiles \
    -p 80:8080 \
    -e SECRET_KEY=YOUR_SECRET_KEY \
    -e DB_ENGINE=django.db.backends.postgresql \
    -e POSTGRES_HOST=db_recipes \
    -e POSTGRES_PORT=5432 \
    -e POSTGRES_USER=djangodb \
    -e POSTGRES_PASSWORD=YOUR_POSTGRES_SECRET_KEY \
    -e POSTGRES_DB=djangodb \
    --name recipes_1 \
    vabene1111/recipes

So my idea was to simply skip the Dockerfile building part of the image and directly install the app with my CloudronManifest.JSON, maybe like this

{
  "title": "Tandoor Recipes",
  "version": "0.1.0",
  "healthCheckPath": "/",
  "httpPort": 8080,
  "addons": {
    "postgresql": {},
    "localstorage": {}
  },
  "manifestVersion": 2,
  "website": "https://docs.tandoor.dev/",
}

If I install this with cloudron install --image vabene1111/recipes --no-wait it installs but the logs show an error that the DB file is not found (excerpt below).

I tried to also build from this image and use the Dockerfile to run a start.sh (idea from this post. But I have difficulties understanding how this build-time script is run every time I start the app. But maybe this is my lack of Docker knowledge.

So my question is, is it not possible to use external non-Cloudron-style build images and pass variables into those images without building it myself?
Any help is highly appreciated.
Thanks.

Regards
Christopher

After an initial user registration I want to disable new users.

I changed the value for enableregistration to false via the file manager in /app/data/config.yml.

Once I restart the app the file is overwritten and the value is set to true again.

How can I prevent new users from registering?
Thanks.
