Version of Marp Tool

v2.5.0

Operating System

Other (fill out in the environment field)

Environment

• docker image https://hub.docker.com/layers/marpteam/marp-cli/latest/images/sha256-5398f735b1a07bd1c3c4f2e39c151ea2b4154d3d2d2cf845d3faae42df945479?context=explore

How to reproduce

1. docker run --rm --init -v $PWD:/home/marp/app/ -e LANG=$LANG marpteam/marp-cli slide-deck.md --pdf

Expected behavior

The PDF is generated

Actual behavior

Conversion is stuck for a few minutes and then fails with Failed converting Markdown. (Target.setAutoAttach timed out. Increase the 'protocolTimeout' setting in launch/connect calls for a higher timeout if needed.)

Additional information

No response

Same error in Gitlab-CI since this morning.

This used to work just fine last week.

I can confirm and reproduce this for Gitlab CI, Github actions, and locally.

We still cannot determine the cause of error. In general, Puppeteer is known as difficult to work on Docker image, so Marp team always recommend to run Marp CLI with installing to the local/CI environment (https://github.com/orgs/marp-team/discussions/375#discussioncomment-4191221).

For debugging Docker image:

• Add -e DEBUG="*" may help to inspect the process of Chrome.
• --entrypoint="" -it marpteam/marp-cli /bin/sh to execute shell.

I am seeing this same thing with the Markdown conversions to PDF when using the Linux container image via Docker Desktop on an arm64 macOS system.

• Script Output

Using the CLI works around this.

Just to provide some debugging information I then ran:

$ docker container run --rm -e DEBUG="*" -v ${PWD}:/home/marp/app/ -e DEBUG="*"  --entrypoint="" -it marpteam/marp-cli:latest  /bin/sh

In case this proves useful:

• adding -e PUPPETEER_HEADLESS_MODE=new does not change the outcome
• the container uses 100% CPU ( one core ); validated using docker stats and top. The runaway process is chrome itself
• after the timeout message is printed, chrome keeps running

The full chrome command line is

Yeah, the timeout has brought by not responding Chrome while Marp CLI is making connection with the browser via Puppeteer.

However, the latest (in-development) image is working PDF conversion correctly on Docker Engine 24.0.2 that was installed to Ubuntu 22.04. I've tested the AMD64 image with docker-ce installed to Ubuntu over WSL2.

$ docker pull marpteam/marp-cli
$ docker run --rm --init -v $PWD:/home/marp/app/ -e LANG=$LANG -e MARP_USER="$(id -u):$(id -g)" marpteam/marp-cli marp.md --pdf
[  INFO ] Converting 1 markdown...

[rombert]

@yhatt - that is good to know, thanks! For the record marpteam/marp-cli:latest@d61b099fe0a4 works just fine for me. I will keep using the 2.14.0 tag until there is a new one.
