如何在Docker中使用wkhtmltopdf [英] How to use wkhtmltopdf with Docker
问题描述
当我在Docker容器中使用wkhtmltopdf(0.12.2.4版,通过apt-get安装)时,它失败了,
When I use wkhtmltopdf (version 0.12.2.4, installed via apt-get) within a Docker container it fails with
QXcbConnection: Could not connect to display
(当我设置环境变量 DISPLAY时= unix0
,我得到 QXcbConnection:无法连接以显示unix0
,这很有意义,因为似乎未安装Xserver)
(When I set the environment variable DISPLAY=unix0
, I get QXcbConnection: Could not connect to display unix0
which makes sense as no Xserver seems to be installed)
似乎有一个无头版本(源),我认为那意味着我不需要Xserver。
There seems to be a headless version (source) and I thought that would mean that I don't need an Xserver.
( xvfb
似乎是另一种选择,但我不确定如何运行它/如何安装)
(xvfb
seems to be another option, but I'm not sure how to run it / what to install)
如果无法将基本映像更改为<$ c,如何在Docker容器中运行wkhtmltopdf $ c> openlabs / docker-wkhtmltopdf ?
How can I run wkhtmltopdf in a Docker container, if I can't change the base image to openlabs/docker-wkhtmltopdf
?
