Laradock 如何使用 apk 而不是 apt-get 添加包

Question

我正在使用 Laradock 部署 Laravel 應用程序。

我在生成 PDF 文件以將其附加到排隊作業的電子郵件中時遇到問題。 待處理的作業由php-worker容器處理。

問題是，當您想將 PDF 附加到排隊的電子郵件（因此，由php-worker容器處理）時，我收到以下錯誤：

“sh：/usr/local/bin/wkhtmltopdf：未找到

這意味着wkhtmltopdf未安裝在php-worker容器中。

因此，查看php-fpm或工作區Dockerfile，我可以看到如何安裝wkhtmltopdf ，如下所示：

#####################################
# 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

如果我將該安裝代碼復制到php-worker容器中，我會收到以下錯誤

/bin/sh: apt-get: 未找到

因此，進一步搜索，似乎php-worker 容器是基於 Alpine 的，並且由於 Alpine 可能需要apk add 。

我嘗試了以下方法：

#####################################
# 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

但我沒有運氣。

錯誤：無法選擇包：wkhtmltopdf（沒有這樣的包）：需要：world[wkhtmltopdf]

我一直在根據這個鏈接編輯 Dockerfile ，這是我到目前為止修改的內容： Dockerfile

但是當我嘗試執行容器以驗證確實安裝了wkhtmltopdf時，

❯ 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

原來它沒有安裝！ 因此，我在我的應用程序中得到了完全相同的錯誤：

“sh：/usr/local/bin/wkhtmltopdf：未找到

另一方面，例如，主管確實工作：

❯ docker container exec php-worker supervisorctl                                                                                                                        ─╯

有人知道如何在 Alpine Dockerfile 中真正安裝 wkhtmltopdf 嗎？

Answer 1

您使用的 PHP 映像是基於 Alpine 3.15 構建的； 看起來wkhtmltopdf不是該版本的 Alpine 中的軟件包：

$ 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]

看起來wkhtmltopdf僅在 3.14 及更早版本中可用（我檢查了 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
fetch https://dl-cdn.alpinelinux.org/alpine/v3.14/community/x86_64/APKINDEX.tar.gz

(103/103) Installing wkhtmltopdf (0.12.6-r0)
Executing busybox-1.33.1-r7.trigger
OK: 196 MiB in 117 packages

這在3.15 的發行說明中有所說明，其中說：

由於缺乏上游支持，QtWebKit 被刪除

由於已知漏洞和缺乏對 qtwebkit 的上游支持，qt5-qtwebkit、kdewebkit、wkhtmltopdf 和 py3-pdfkit 已被刪除。 其他程序已調整為在適當的情況下使用 qt5-qtwebengine。 wkhtmltopdf 最直接的替代品是 weasyprint，它可以在 Alpine Linux 社區存儲庫中找到。 puppeteer 和 pandoc 也是選項，具體取決於您的需要。 有關詳細信息，請參閱#12888。

您可以使用上游 Dockerfile在較舊的 Alpine 版本之上干構建自己的 PHP 基礎映像，或者您可以嘗試從 vanilla alpine:3.14映像開始並使用apk安裝 php。

或者只是堅持使用基於 Ubuntu 的圖像，它仍然打包wkhtmltopdf 。
