Hello! thanks! I'm debugging a deployment with an additional Dockerfile
I'm not seeing the logging and I'm wondering if it's ending up elsewhere? I can see the added docker info in 'wasp dockerfile' but my logging doesn't show up. I'm also curious if docker-compose file will be executed as well? would I be better off running separate containers on the server?

Hi @3ghan. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Hello! When you create a custom Dockerfile in your project's root directory, Wasp appends its contents at the bottom of the default multi-stage Dockerfile. This means that any logging you have added in your custom Dockerfile should be executed during the Docker build and run process. However, the visibility of these logs can depend on how you're running and monitoring your Docker containers.
If you're not seeing the logs, it might be due to how the Docker container is being run or monitored. You might want to check the logging settings of your Docker environment or the platform where you're deploying your Docker containers.
As for the
docker-compose.yml, Wasp doesn't currently have built-in support for executing a docker-compose.yml file during the build or deployment process. If you need to use Docker Compose to manage multiple containers, you would need to handle this separately from the Wasp build and deployment process.
Running separate containers can have its advantages, such as isolating the services and scaling them independently. However, it would also mean managing the communication between these containers yourself.
For more details on customizing the Dockerfile in Wasp, you can refer to the official documentation (https://wasp-lang.dev/docs/advanced/deployment/overview#customizing-the-dockerfile). If you have more questions or need further assistance, you can also join the Wasp Discord community (https://discord.gg/rzdnErX).

Sorry @3ghan, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist:
Perhaps try again in 15mins?here's the output from wasp dockerfile, can you see any issues @kapa.ai :
FROM node AS base
RUN apk --no-cache -U upgrade
FROM base AS server-builder
RUN apk add --no-cache python3 build-base libtool autoconf automake
WORKDIR /app
COPY src ./src
COPY package.json .
COPY package-lock.json .
COPY server .wasp/build/server

Install npm packages, resulting in node_modules/.
RUN npm install && cd .wasp/build/server && npm install

Building the server should come after Prisma generation.

Let me check the knowledge base for you. One moment! :books:
----------------------
The Dockerfile you provided seems to be a combination of the Wasp-generated Dockerfile and a custom Dockerfile for a tool called Flowise.
The Wasp part of the Dockerfile looks fine. It follows the standard multi-stage build process, installing dependencies, copying files, and setting up the environment for a production build.
The Flowise part of the Dockerfile also seems fine. It installs necessary dependencies, sets up Puppeteer to use a pre-installed Chromium browser, installs Flowise globally, and sets up an entry point that checks for the
PORT environment variable and starts Flowise.
However, there are a few things to note:
1. The FROM node:20-alpine line is starting a new build stage. This means that the final Docker image will only contain the layers from this line onwards. It won't include any of the layers from the Wasp part of the Dockerfile. If you want to include both Wasp and Flowise in the same Docker image, you might need to adjust your Dockerfile accordingly.
2. The USER root line is setting the user for the following Docker instructions to root. This could potentially be a security risk depending on your deployment environment.
3. The WORKDIR /data line is setting the working directory to /data. This directory doesn't seem to be used in the rest of the Dockerfile. If your Flowise application needs to access files in this directory, you might need to copy them into the Docker image.
4. The ENTRYPOINT command for Flowise checks if the PORT environment variable is set. If it's not, it will exit with an error. Make sure to set this environment variable when running your Docker container.
Remember to build and test your Docker image locally before deploying it to a live environment. If you encounter any issues, the error messages should give you clues on what needs to be fixed.

Perhaps try again in 15mins?anybody reading this, looks like a -no- from wasp re/multiple containers(?) and no docker-compose from fly.io, closest solution seems to be https://fly.io/docs/apps/processes/
but looks unlikely to be worth the extra work vs. just hosting separate entities
@3ghan I am nto sure I got it, what are you trying to do?
So Wasp currently has a notion of a single Dockerfile, which is used to spin up the api-server (backend).
You can customize that Dockerfile.
If you want to do sometihng more complex, like have some other stuff next to it that needs its own Dockerfile and so on, or even use docker compose, that is up to you, it is not something Wasp directly deals with or recognizes.
Wasp does have special thing for deployment to Fly though, where it also puts client into Dockerfile and deploys it that way, but that is another thing.
Might be best if you tell me exactly what you want to do and we can figure it out from there!
