Laradock如何使用apk而不是apt-get添加包

Question

我正在使用Laradock来部署Laravel应用程序。

我正面临一个问题，生成一个PDF文件附加在电子邮件在队列作业． 挂起的作业由php-worker容器处理。

问题是，当您要将PDF附加到排队的电子邮件(因此，由php-worker容器处理)时，我得到以下错误:

"sh:/usr/local/bin/wkhtmltopdf: not found

表示wkhtmltopdf未安装在php-worker容器中。

所以，看看php-fpm或工作区Dockerfile，我可以看到如何安装wkhtmltopdf如下:

#####################################
# wkhtmltopdf:
#####################################
USER root
ARG INSTALL_WKHTMLTOPDF=false
RUN if [ ${INSTALL_WKHTMLTOPDF} = true ]; then 
apt-get install -yqq 
libxrender1 
libfontconfig1 
libx11-dev 
libjpeg62 
libxtst6 
fontconfig 
libjpeg62-turbo 
xfonts-base 
xfonts-75dpi 
wget 
&& wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.stretch_amd64.deb 
&& dpkg -i wkhtmltox_0.12.6-1.stretch_amd64.deb 
&& apt -f install 
;fi

如果我将该安装代码复制到php-worker容器中，我会得到以下错误

/bin/sh: apt-get: not found

因此，进一步搜索，似乎php-worker容器是基于Alpine的，并且可能需要apk add，因为Alpine。

我已经试过了:

#####################################
# wkhtmltopdf:
#####################################
USER root
ARG INSTALL_WKHTMLTOPDF=false
RUN if [ ${INSTALL_WKHTMLTOPDF} = true ]; then 
apk add --no-cache 
libxrender1 
libfontconfig1 
libx11-dev 
libjpeg62 
libxtst6 
fontconfig 
libjpeg62-turbo 
xfonts-base 
xfonts-75dpi 
wget 
wkhtmltopdf 
;fi

但是我运气不好。

错误:无法选择软件包:wkhtmltopdf(没有这样的软件包):required by: world[wkhtmltopdf]

我一直在编辑Dockerfile基于这个链接，这是我已经修改到目前为止:Dockerfile

最后，wkhtmltopdf似乎要安装:

当我尝试执行容器以验证wkhtmltopdf是否确实安装时，

❯ docker container exec php-worker /usr/local/bin/wkhtmltopdf -V                                                                                                        ─╯
OCI runtime exec failed: exec failed: container_linux.go:380: starting container process caused: exec: "/usr/local/bin/wkhtmltopdf": stat /usr/local/bin/wkhtmltopdf: no such file or directory: unknown

显示没有安装!因此，我在我的应用程序中得到了完全相同的错误:

"sh:/usr/local/bin/wkhtmltopdf: not found

另一方面，例如，主管确实在工作:

❯ docker container exec php-worker supervisorctl                                                                                                                        ─╯

有没有人知道如何安装wkhtmltopdf在高山Dockerfile真正的?

Answer 1

您使用的PHP图像是在Alpine 3.15上构建的;看起来wkhtmltopdf在那个版本的Alpine中没有包:

$ docker run --rm alpine:3.15 sh -c 'apk add --update wkhtmltopdf'
fetch https://dl-cdn.alpinelinux.org/alpine/v3.15/main/x86_64/APKINDEX.tar.gz
fetch https://dl-cdn.alpinelinux.org/alpine/v3.15/community/x86_64/APKINDEX.tar.gz
ERROR: unable to select packages:
wkhtmltopdf (no such package):
required by: world[wkhtmltopdf]

看起来wkhtmltopdf只在3.14和更早的版本可用检查3.14和3.13):

$ docker run --rm alpine:3.14 sh -c 'apk add --update wkhtmltopdf'
fetch https://dl-cdn.alpinelinux.org/alpine/v3.14/main/x86_64/APKINDEX.tar.gz

这在3.15的发行说明中有说明，其中说:

QtWebKit由于缺乏上游支持而被删除

qt5-qtwebkit, kdewebkit, wkhtmltopdf和py3-pdfkit由于已知漏洞和缺乏上游对qtwebkit的支持已被删除。其他程序已调整为在适当情况下使用qt5-qtwebengine。wkhtmltopdf最直接的替代品是weasyprint，它可以在Alpine Linux社区存储库中获得。Puppeteer和pandoc也可以选择，这取决于你的需要。查看#12888了解更多信息。

你可以使用上游Dockerfile在旧的Alpine版本上构建自己的PHP基础镜像，或者你可以尝试从alpine:3.14镜像开始，使用apk安装PHP。

或者只使用基于ubuntu的映像，它仍然是打包的wkhtmltopdf.
