docker项目，使用LibreOffice实现word转pdf

Question

问题遇到的现象和发生背景

遇到了一个word转pdf的需求，经过几番波折，决定使用LibreOffice+jodconverter的方式来实现

操作环境、软件版本等信息

现在的情况是，在windows下以及linux下都能实现word转pdf，
但是一旦使用docker来部署项目，将LibreOffice在Linux的安装路径挂载到docker，启动项目，调用到word转pdf的功能时，就会爆出下面的错误

我想要达到的结果

可以实现word转pdf的功能

Answer 1

基于Monster 组和AIGC的调写：若有帮助，还望采纳~~：

• 错误信息表明，启动的LibreOffice二进制文件/opt/libreoffice7.5/program/soffice.bin在容器中找不到。这通常是因为以下几个原因：

1. LibreOffice没有被正确安装：在构建Docker镜像时，要确保LibreOffice软件包已经被正确安装到指定路径下。

2. 挂载卷的问题：如果你是通过挂载卷的方式来让Docker容器访问宿主机的LibreOffice安装目录，要确保该卷的挂载路径与容器内的预期路径一致。

3. 文件系统权限：在某些情况下，容器可能没有权限访问挂载的目录，你可能要调整权限设置。

4. 依赖问题：可能是缺少了LibreOffice运行所需要的某些依赖库，尤其是在轻量级的容器环境中。

为了解决这个问题，你可以尝试以下步骤：

• 确保Docker镜像构建过程中包含了LibreOffice的安装步骤，并且安装路径与容器内的预期路径匹配。
• 检查Docker容器的挂载卷设置，确保LibreOffice的路径被正确挂载。
• 在容器内手动运行/opt/libreoffice7.5/program/soffice.bin以检查是否能够成功执行。
• 检查并安装任何可能缺失的依赖库。
