[Aarbel]

Impossible to use docker image of pdf-export server for dev test, even for production, do you need help to change it ? @bmblb

Putting FROM --platform=linux/amd64 node:16.15.0 in the Dockerfile looks to solve the E: Unable to locate package google-chrome-stable problem, cf https://dev.to/docker/unable-to-locate-package-google-chrome-stable-b62

In addition to that, to run well the container on Macbook Pro M1 with silicon ship, i had to follow this Docker doc: https://collabnix.com/warning-the-requested-images-platform-linux-amd64-does-not-match-the-detected-host-platform-linux-arm64-v8/

Inside Docker

• Use Rosetta for x86/amd64 emulation on Apple Silicon (Settings > General)
• Use Virtualization framework (Settings > Features in Develoment)

And run

docker build --platform linux/amd64 -t bryntum_pdfexport_server .
docker run --platform linux/amd64 bryntum_pdfexport_server

But i still have the hummus issue while running the container:

 | node:internal/modules/cjs/loader:1189
 |   return process.dlopen(module, path.toNamespacedPath(filename));
 |                  ^

 | }
exited with code 1

I also don't understand what i should do reading this code block in the dockerfile

# If running Docker >= 1.13.0 use docker run's --init arg to reap zombie processes, otherwise
# uncomment the following lines to have `dumb-init` as PID 1
# ADD https://github.com/Yelp/dumb-init/releases/download/v1.2.0/dumb-init_1.2.0_amd64 /usr/local/bin/dumb-init
# RUN chmod +x /usr/local/bin/dumb-init
# ENTRYPOINT ["dumb-init", "--"]

Is this Dockerfile basically made for docker version < 1.13 (we are now at version 4 of docker)

[Aarbel]

Also this one is not clear about "in which cases it should be useful"

Cf

# Uncomment to skip the chromium download when installing puppeteer. If you do,
# you'll need to launch puppeteer with:
#     browser.launch({executablePath: 'google-chrome-stable'})
# ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true

Impossible to use docker image of pdf-export server for dev test, even for production

Not so long ago I successfully built this image and uploaded to dockerhub. In fact I did it for our M1 user and it works for him in production. I suggest to grab container from docker hub.

do you need help to change it ?

Feel free to prepare a PR, I'll take a look

@bmblb

i can't use the docker hub one as i have the error

Using default tag: latest
Error response from daemon: manifest for bryntum/pdf-export-server:latest not found: manifest unknown: manifest unknown

Are you sure you are using last version of Docker ?

I'm on 4.18.0 (104112)

[bmblb]

try bryntum/pdf-export-server:1.0.1

I solved this problem using ChatGPT:

Magic result:

It seems like the issue is caused by a mismatch between the required glibc version and the one available in the Docker image. The error message indicates that the required version is GLIBC_2.29, but it's not found in your current image.

To fix this issue, you can try updating the base image to a newer version of Node that might include the required glibc version. Here's an updated version of your Dockerfile with a newer base image:

FROM --platform=linux/amd64 node:17

# Rest of the Dockerfile remains the same.

This worked for me but if that still doesn't work, you can try using a different base image with the required glibc version. In this case, you can use the ubuntu:20.04 image and install Node.js manually:

FROM --platform=linux/amd64 ubuntu:20.04

# Install Node.js
RUN apt-get update && \
    apt-get install -y curl && \
    curl -sL https://deb.nodesource.com/setup_16.x | bash - && \
    apt-get install -y nodejs

# Rest of the Dockerfile remains the same.

This should provide you with a more recent version of glibc that satisfies the required dependencies. Make sure to adjust the rest of the Dockerfile accordingly, as some commands or package names might be different between base images.

But i still hadthe error:

Http server started on port 8081
node:events:505
      throw er; // Unhandled 'error' event
      ^

Error: listen EADDRINUSE: address already in use :::8081

Which i solved removing other Docker runs (the lsofcommand wasn't working idk why)

[bmblb]

port forwarding issue can be resolved using docker compose config
