dscout / wkhtmltopdf-buildpack Goto Github PK

Heroku released an update to its Heroku 16 stack on December 18. Since that update to our Heroku instances, pdf rendering will only temporarily work on a new branch deploy or instance restart. After ~5 mins pdf rendering silently fails (ie. no information presented in log file).

Final log entry is:
2019-02-01T17:37:56.044912+00:00 app[web.1]: WICKED

That is followed by a series of rack-timeout notifications until we reach the Heroku limit and the call fails.

Spoke with Heroku support and they redirected me to post here.

After installing this buildpack alongside the default python webpack i can't seem to find the executable of wkhtmltopdf. Neither from my repo nor from command line. Can someone help me out regarding this?

In command line I tried just heroku run wkhtmltopdf --app <myapp>. From my understand it should display all the wkhtmltopdf options, at least that's what happening when I do this on my local system.

When deploying that is my log (maybe it helps):

@sorentwo my html page has images but this images are not shown in generated PDF. I had such problem when on my local machine was version of wkhtmltopdf installed via gem.

Added this to a Heroku (heroku-16) Django app.
Files are installed in app/bin:
~/bin $ find -maxdepth 1 -type f -ls -exec file -b {} \; 15619982 38816 -rwx------ 1 u46936 dyno 39745960 Jan 20 2016 ./wkhtmltopdf ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.18, stripped 15619983 38740 -rwx------ 1 u46936 dyno 39666344 Jan 20 2016 ./wkhtmltoimage ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.18, stripped

When using Pdfkit.to_pdf the following error is returned:

OSError('No wkhtmltopdf executable found: "If this file exists please check that this process can read it. Otherwise please install wkhtmltopdf - https://github.com/JazzCore/python-pdfkit/wiki/Installing-wkhtmltopdf'

When running wkhtmltopdf -V:

bash: wkhtml: command not found

Should I set the path variable? If so, how?

Just noting the buildpack doesn't work as-is on the new stack.

wkhtmltopdf: error while loading shared libraries: libXrender.so.1: cannot open shared object file: No such file or directory

I'm seeing this error when attempting to deploy to heroku:

Presumably caused by this line:

hey,

any way you can update this to the latest 0.12.1 under ubuntu 14.04 so it can be deployed on heroku and so on ?

Hello,

wkhtmltopdf has moved the downloads provider from SourceForge to gna.org. As mentioned in the linked message, all earlier downloads have been removed from SourceForge and you are strongly advised to migrate to the new URLs. The following files in your repository will need to be updated:

• bin/compile

It is recommended to either subscribe to the mailing list or Twitter feed to receive updates on new releases and further changes.

Thanks,
wkhtmltopdf maintainer

I just found this buildpack, and have a suggestion: add tags so it is possible to fix the wkhtmltopdf version. In the past wkhtmltopdf broke my PDFs after updates. If you'd add tags, these could be used in the .buildpacks-file, so nobody is accidentally updated.

Incidentally, 0.12.4 breaks my pdfs, so it would be great if there'd be a tag for 0.12.3

I see this line under the usage documentation:

$ echo 'https://github.com/heroku/heroku-buildpack-ruby.git' >> .buildpacks

However I don't understand why Ruby specifically is necessary since neither your code or the wkhtmltopdf debian package requires Ruby.

I am wondering if you more have that line there as an example of using it alongside a site that is already using a Ruby build pack.

Is it safe to assume that I could replace that line with whatever build pack I am already using? If so, I might kick a quick pull request your way with a README update. :)

How might I integrate this into another buildpack: https://github.com/AdmitHub/meteor-buildpack-horse ? Basically trying to install wkhtmltopdf in Heroku to do PDF rendering.

Just tried your buildpack but something went wrong while downloading the package:

remote: =====> Downloading Buildpack: https://github.com/dscout/wkhtmltopdf-buildpack.git

This regression is very noticeable on macOS, and mildly noticeable on Linux.

Could we roll back to 0.12.3 or at least allow an env var to choose a version?

Hello,

I'm trying to use this buildpack but cannot figure out how to execute wkhtmltopdf. If I try:

heroku run bash
wkhtmltopdf -V
bash: wkhtmltopdf: command not found

and if I check /bin , wkhtmltopdf is not there.

However the buildpack logs out when compiling the app:

 ...
-----> wkhtmltopdf-buildpack app detected
-----> Using wkhtmltopdf Debian package from cache
-----> Unpacking Debian package
-----> Setting permissions
-----> Moving binaries to the right place

-----> Discovering process types
       Procfile declares types -> web
-----> Compressing...
       Done: 125.4M
-----> Launching...

Do you have any ideas of where I should start troubleshooting?

Thanks!

Hello
I'm not sure if this is a problem in the free heroku dyno but I tried to use the wkhtmltopdf-buildpack and I didn't get success. This is my heroku logs:

I'm not sure about how to debug this issue, but could you help? Is adding dynos an option in this case? Thanks

A couple of days ago wkhtmltopdf 0.12.5 has been released. It turns out the buildpack doesn't work out-of-the-box when setting the version in config (the release url seems to have changed). Can you make the buildpack work for the new version?

I would love to see my builds go faster.

I would do a PR but I'm not sure how I would go about testing it personally. I assume I can fork and point the build pack at my repo.
