Is it possible for development to have autoreload ? (docker-compose exemple)

[outer prairie]

Is it possible to autoreload ? here is an exemple with npm run dev:watch

version: '3'
services:
    mongodb:
        image: mongo:4
        ports:
            - 27017:27017
    app:
        build: nodejs-with-mongodb-api-example
        command: npm run dev:watch
        ports:
            - 4000:4000
        environment: 
            MONGO_URL: mongodb
            PORT: 4000
        volumes:
            - ./nodejs-with-mongodb-api-example:/src/
            - nodemodules:/src/node_modules
        links:
            - mongodb
        depends_on: 
            - mongodb

volumes:
    nodemodules: {}

Is it the same, With python SDK, as : with_mounted_directory("/src", "./nodejs-with-mongodb-api-example")

We do not support auto reload for now, but thanks to caching it should be pretty fast to recreate a container if you use Dagger to expose a service

Hey @outer prairie this is not possible today - here's an issue tracking it, please add any additional feedback that you might have there.

Hello, sorry for the delay. I am not sure it is exactly the same. Tell me if I am wrong but if one mount a volume, it is the duty of the server to watch the file change not dagger.

Live development here seems more linked to another use case, which is : watch the change of the dagger code and reload. Am I wrong ?

[outer prairie]

From my experience it is not really fast. Running directly through docker or on my machine is less than a second. Dagger should not need to rebuild and redeploy. Maybe I am using dagger on a wrong use case

[hardy stirrup]

Ohhh I don't think it's the right use case, Dagger is used to execute specific task on your project, like linting, building, serve an app etc...
What kind of operation are you trying to accomplish that should be watched if dagger code changes?

[outer prairie]

Dagger features makes it almost a good replacement for docker compose / Dockerfile. I use dockerfile + docker compose sharedwith other developper to reproduce production environment for local development. Web App + database.

I see, yeah Dagger is a good use case for it, but we first need to support live reloading
I use Dagger to reproduce my prod environment but it's true that I manually rerun my dagger call when I want to test an update

Which is quite fine because Go has no watcher by default so it's not that impacting compared to my non-dagger experience
