App with multiple endpoints. How to share addons?

[baptistearno]

Hi,

I'm the founder of https://typebot.io. I'd like to package Typebot for Cloudron.

Typebot is basically composed of 2 applications: the builder (chatbot editor) and the viewer (chatbot execution).

version: '3.3'
services:
  typebot-db:
    image: postgres:13
    restart: always
    volumes:
      - db_data:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=typebot
      - POSTGRES_PASSWORD=typebot
  typebot-builder:
    image: baptistearno/typebot-builder:latest
    restart: always
    depends_on:
      - typebot-db
    ports:
      - '8080:3000'
    extra_hosts:
      - 'host.docker.internal:host-gateway'
    # See https://docs.typebot.io/self-hosting/configuration/builder for more configuration options
    environment:
      - DATABASE_URL=postgresql://postgres:typebot@typebot-db:5432/typebot
      - NEXTAUTH_URL=<your-builder-url>
      - NEXT_PUBLIC_VIEWER_URL=<your-viewer-url>
      - ENCRYPTION_SECRET=<your-encryption-secret>
      - ADMIN_EMAIL=<your-admin-email>
  typebot-viewer:
    image: baptistearno/typebot-viewer:latest
    restart: always
    ports:
      - '8081:3000'
    # See https://docs.typebot.io/self-hosting/configuration/viewer for more configuration options
    environment:
      - DATABASE_URL=postgresql://postgres:typebot@typebot-db:5432/typebot
      - NEXT_PUBLIC_VIEWER_URL=<your-viewer-url>
      - ENCRYPTION_SECRET=<your-encryption-secret>
      - NEXTAUTH_URL=<your-builder-url>
volumes:
  db_data:

From what I understand, I'll need to implement 2 distinct Cloudron apps?

When it comes to postgresql addons, can I make sure it is shared between the 2 apps?

@girish @nebulon what is the best way to solve the issue raised by @baptistearno?

[jdaviescoates]

I don't know the answer but I'd look for clues in the packages of other apps with multiple end points like eg Minio (I think)

[nebulon]

For this you probably want to use the multiDomain feature https://docs.cloudron.io/packaging/manifest/#multidomain

Or also if one of the two processes can work off a subpath of the same domain, you may add a reverse proxy in the app to proxy pass to the corresponding internal server?

Is the container run in read-only mode?

My start script need to create a file but I keep getting the error: "touch: cannot touch './builder/apps/builder/public/__env.js': Read-only file system"

I tried to specifically enable all modes to that public folder with RUN chmod 777 -R ./builder/apps/builder/public && chmod 777 -R ./viewer/apps/viewer/public. But that just won't do it.

Here are the files: https://github.com/baptisteArno/typebot.io/pull/550/files

Am I missing something?

@baptistearno make sure to se it up to run from /app/data and not /app/code

[baptistearno]

@robi I tried to run the script from the /app/data folder (https://github.com/baptisteArno/typebot.io/pull/550/commits/6da7ade5dd4a4f24c6185472b66df0715c94c6a5#diff-f04ded0885f91a28ae388b09ec3477ec378337f483257bf22e0eaf813c3704e5) but no luck.

Still getting: touch: cannot touch './builder/apps/builder/public/__env.js': Read-only file system

Did I understand correctly what you suggested?

[nebulon]

So in Cloudron only the folders /app/data, /run/ and /tmp/ are write-able. The app code should remain in read-only storage, but if an app needs to write to disk, then depending on the use-case one of those 3 folders should be symlinked or configured to be used. Note that only /app/data will get backed up.

[robi]

@baptistearno looks like you need to adjust the ENVSH_* variables to something more appropriate to what @nebulon said.

[baptistearno]

EDIT: fixed! I increased the container resources

Thank you for the help guys @robi @nebulon, I'm almost there!

Now, I have an issue with running the 2 apps using supervisor. Here is the final logs:

It seems to properly launch the 2 apps but then it doesn't succeed in doing the health check.
The server seems to be slow… The logs take some time to load etc… but when I check the resource usage, it is just fine:

Is the container restricted in terms of resource?

[jeau]

thanks for the work @baptistearno

by default each app has a memory limit set at 256MB, in your manifest CloudronManifest.jsonyou can adjust this default value for your app.

https://docs.cloudron.io/packaging/manifest/#memorylimit

[girish]

@baptistearno Just saw https://docs.typebot.io/self-hosting/cloudron . This is awesome!

Are you open to having the app published on the App Store ? If so, I can create a repo in our gitlab, give you permissions as well and we can proceed to get it published. Note that GitLab is only for the cloudron package and not for your app development (which can continue wherever you want).

[staypath]

@baptistearno Man, this is so great. Looks like a lot of work was put in. Awesome job, and thanks for the effort!

@Lanhild can you respond with the link to the message from @girish above? (hover over the #13 link)

[girish]

I left a note in that issue.
