Failed to write file pdf: No such file or directory (2) when using print-to-pdf

[frederikhors]

Hi guys! Thank you for your amazing work!

I'm trying to build a custom Dockerfile using your one:

FROM alpine:3.17

RUN apk upgrade --no-cache --available \
    && apk add --no-cache \
      chromium-swiftshader \
      ttf-freefont \
      font-noto-emoji \
    && apk add --no-cache \
      --repository=https://dl-cdn.alpinelinux.org/alpine/edge/testing \
      font-wqy-zenhei

# I tried with these too, same error
# RUN mkdir -p /usr/src/app \
#     && adduser -D chrome \
#     && chown -R chrome:chrome /usr/src/app

# USER chrome
# WORKDIR /usr/src/app

ENV CHROME_BIN=/usr/bin/chromium-browser \
    CHROME_PATH=/usr/lib/chromium/

ENV CHROMIUM_FLAGS="--disable-dev-shm-usage --disable-software-rasterizer"

COPY ./app/ .

CMD ./start.sh

start.sh is like this:

#!/bin/sh

# other things here

./app

The app starts. The app calls chrome with the below OS command (from dir /usr/bin):

chromium-browser --headless --no-sandbox --disable-setuid-sandbox --disable-gpu --disable-dev-shm-usage --run-all-compositor-stages-before-draw --print-to-pdf='/tmp/test.pdf' /tmp/test.html

Chrome starts but errors with:

[0206/124936.861070:WARNING:dns_config_service_linux.cc(429)] Failed to read DnsConfig.\n
[0206/124936.861016:ERROR:bus.cc(399)] Failed to connect to the bus: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory\n

[0206/124937.140474:ERROR:headless_shell.cc(219)] Failed to write file '/tmp/test.pdf': No such file or directory (2)\n"

As you can see the MAIN error is: Failed to write file '/tmp/test.pdf': No such file or directory (2)\n"

What is causing this?

Is this a permissions issue?

What is the execution context? How do you run the container?

Cannot reproduce it on direct call to chromium-browser ... --print-to-pdf='/tmp/test.pdf' ... from an image built from the dockerfile you gave.
