Not working in docker

java.lang.UnsatisfiedLinkError: Unable to load library '/tmp/io.woo.htmltopdf/wkhtmltox/0.12.4/libwkhtmltox.so': Native library (tmp/io.woo.htmltopdf/wkhtmltox/0.12.4/libwkhtmltox.so) not found in resource path

It seems to work for me in a simple test with a stock library/java docker container. It appears that for some reason in your case there's a failure to copy wkhtmltopdf library resources. Are you using version 1.0.2?

[lgabeskiria]

We have the following Dockerfile:

FROM frolvlad/alpine-oraclejdk8:slim

VOLUME /tmp
ADD project-1.0-SNAPSHOT.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]

We are building docker image in Jenkins, then saving image in AWS

[benbarkay]

@lgabeskiria it looks like the library is being copied to /tmp and JNA is attempting to load it, the (rather misleading) error comes from that some dependencies are missing in the alpine image:

Error loading shared library libXrender.so.1: No such file or directory (needed by /tmp/io.woo.htmltopdf/wkhtmltox/0.12.4/libwkhtmltox.so)
Error loading shared library libfontconfig.so.1: No such file or directory (needed by /tmp/io.woo.htmltopdf/wkhtmltox/0.12.4/libwkhtmltox.so)
Error loading shared library libfreetype.so.6: No such file or directory (needed by /tmp/io.woo.htmltopdf/wkhtmltox/0.12.4/libwkhtmltox.so)
Error loading shared library libXext.so.6: No such file or directory (needed by /tmp/io.woo.htmltopdf/wkhtmltox/0.12.4/libwkhtmltox.so)
Error loading shared library libX11.so.6: No such file or directory (needed by /tmp/io.woo.htmltopdf/wkhtmltox/0.12.4/libwkhtmltox.so)
Error loading shared library libstdc++.so.6: No such file or directory (needed by /tmp/io.woo.htmltopdf/wkhtmltox/0.12.4/libwkhtmltox.so)

If you could find a way to install these libraries into your docker image, htmltopdf should work fine.

You can generate this output by running ldd libwkhtmltox.so in your container (where libwkhtmltox.so is the library file from the project)

[benbarkay]

If you add the following to your docker build script that should solve it:

RUN sh -c 'apk update && apk add libx11 libxext libxrender libstdc++ freetype fontconfig libssl1.0'

[miguelbaldi]

@benbarkay libc6-compat is missing too. I was able to get working with: RUN sh -c 'apk --update add libc6-compat libx11 libxext libxrender libstdc++ freetype fontconfig libssl1.0'

[lgabeskiria]

@benbarkay Thanks that worked for us (except fonts). But there is some strange behaviour: When calling API for first time it generates pdf, but second time it just goes to timeout.

I think the converter should be singleton.

[benbarkay]

@miguelbaldi his docker image has glibc2 installed on it so he did not need it. But that's good to know. @lgabeskiria could you open another issue with a snippet that would reproduce the behavior?

In any case, this has been helpful. I'll add this troubleshooting to the README.

[jernejcvek]

In my case (Ubuntu 18.04), the package libpng12-0 was missing:

Exact reason for this issue is that libpng12is no longer available in the Ubuntu repository archives. In-fact, Ubuntu dropped it from Ubuntu 16.10 too.

Possible solution is to install this package manually: wget http://security.ubuntu.com/ubuntu/pool/main/libp/libpng/libpng12-0_1.2.54-1ubuntu1.1_amd64.deb && sudo dpkg -i libpng12-0_1.2.54-1ubuntu1.1_amd64.deb && sudo rm -f libpng12-0_1.2.54-1ubuntu1.1_amd64.deb
