EACCES: permission denied, open '/home/marp/app/untitled.pdf'

When I try to use it by docker, it gives me an error.
I'd really appreciate it if you could help me with this problem


Docker version 18.09.4, build d14af54

It should doubt permission or owner of directories. (ls -la | grep ^d)

It's not the best answer but adding --privileged option instead of running with sudo might be help you.

We close this issue that has no progress for a week. Please report more information by executing the presented command if still troubling now.

I hit the same problem, to work around it I changed the container user. Note -u "node" below.

docker run -u "node" --rm -v $PWD:/home/marp/app/ -e LANG=$LANG marpteam/marp-cli pres.md --pdf

To figure this out I ran the container with a custom entry point to get shell access and see which user had permissions over /home/marp/app

$  docker run --entrypoint "sh" -it -v $PWD:/home/marp/app/ -e LANG=$LANG marpteam/marp-cli
~/app $ pwd
/home/marp/app
~/app $ ls -la
total 256
drwxr-xr-x    3 node     node          4096 Jul  2 09:06 .
drwxr-sr-x    1 marp     marp          4096 Jul  2 09:20 ..

Oh, I forgot to mention in my previous comment that I tried this and it didn't help

If you think Marp CLI's Docker image is assigning marp user meaningless, you may send pull request.

marp-cli/Dockerfile

Line 25 in e79afe2

USER marp

UPDATE: It seems to be better following Puppeteer's best practice to run in Docker. We have to research about user permission of mounted directory.

I also just encountered this same issue. Here is another workaround:

mkdir directory_anyone_writes_to
cp Downloads/index.md ~/directory_anyone_writes_to/ # put your md file in there
chmod -R 0777 directory_anyone_writes_to/  # grant very loose permission
cd directory_anyone_writes_to/
docker run --rm --init -v $PWD:/home/marp/app/ -e LANG=$LANG marpteam/marp-cli index.md --pdf
