[Pascal76]

Hi

Could someone provide a working docker file for the V4 please ?

Thank you.

Built for myself using the one below.
I add some fonts (for example google fonts) - put them into folder fonts.

from node:22

WORKDIR /usr/share/fonts/truetype
ADD fonts/* /usr/share/fonts/truetype/
# ADD src/fonts/OpenSans-Regular.ttf OpenSans-Regular.ttf
# ADD src/fonts/OpenSans-Light.ttf OpenSans-Light.ttf
# ADD src/fonts/OpenSans-Semibold.ttf OpenSans-Semibold.ttf
# ADD src/fonts/OpenSans-Bold.ttf OpenSans-Bold.ttf
# ADD src/fonts/OpenSans-ExtraBold.ttf OpenSans-ExtraBold.ttf
# ADD src/fonts/OpenSans-Italic.ttf OpenSans-Italic.ttf
# ADD src/fonts/OpenSans-LightItalic.ttf OpenSans-LightItalic.ttf
# ADD src/fonts/OpenSans-BoldItalic.ttf OpenSans-BoldItalic.ttf
# ADD src/fonts/OpenSans-SemiboldItalic.ttf OpenSans-SemiboldItalic.ttf
# ADD src/fonts/OpenSans-ExtraBoldItalic.ttf OpenSans-ExtraBoldItalic.ttf

It displays:

(node:7) [DEP0040] DeprecationWarning: The punycode module is deprecated. Please use a userland alternative instead.
(Use node --trace-deprecation ... to show where the warning was created)

Also the "height" on "chart" on the json file is ignored.
It uses the default value :(
I have to add the value as argument on the /usr/local/bin/highcharts-export-server command line.

And the png creation takes 0:02.69 vs 0:00.63 on the old version without pupetter (maybe due the the display of the warning)
(I don't use highcharts as a server)

@ba1dr, maybe this will help you: #488 (comment)

FYI, I also made this d029d00 addition, because of this error ...

... according to --allowFileResources: Controls the ability to inject resources from the filesystem. This setting has no effect when running as a server (defaults to false). mentioned here https://github.com/highcharts/node-export-server/blob/master/README.md#command-line-arguments, the file resources.json should only be checked for when running as a Server (which I didn't check for in my change) and allowFileResources=true.
