依赖工具 6 | 7 | 本项目是在 MacOS 下开发的，涉及到的工具是平台无关的，对于 Linux 和 Windows 桌面系统应该也同样适用。在开始本例之前请确保如下工具已经正确的安装，更新到最新版本，并进行正确的配置。 8 | 9 | * [Docker](https://www.docker.com/) 10 | * [Funcraft](https://github.com/alibaba/funcraft) 11 | 12 | 对于 MacOS 用户可以使用 [homebrew](https://brew.sh/) 进行安装： 13 | 14 | ```bash 15 | brew cask install docker 16 | brew tap vangie/formula 17 | brew install fun 18 | ``` 19 | 20 | Windows 和 Linux 用户安装请参考： 21 | 22 | 1. https://github.com/aliyun/fun/blob/master/docs/usage/installation.md 23 | 2. https://github.com/aliyun/fcli/releases 24 | 25 | 安装好后，记得先执行 `fun config` 初始化一下配置。 26 | 27 | **备注: 本文介绍的技巧需要 Fun 版本大于等于 3.0.6 。** 28 | 29 | ## 初始化 30 | 31 | 使用 fun init 命令可以快捷地将本模板项目初始化到本地。 32 | 33 | ```bash 34 | $ fun init vangie/libreoffice-example 35 | ``` 36 | 37 | **修改 template.yml 文件，将 OSS_REGION 和 OSS_BUCKET 改为您账号的 OSS 配置。** 38 | 39 | ## 安装依赖 40 | 41 | 42 | ```bash 43 | $ fun install 44 | ``` 45 | 46 | ## 本地测试 47 | 48 | ```bash 49 | # 本地测试 nodejs8 版本 50 | $ DISABLE_BIND_MOUNT_TMP_DIR=true fun local invoke word2pdf-nodejs8 51 | 52 | # 本地测试 python3 版本 53 | $ DISABLE_BIND_MOUNT_TMP_DIR=true fun local invoke word2pdf-python3 54 | 55 | # 本地测试 custom 版本 56 | $ DISABLE_BIND_MOUNT_TMP_DIR=true fun local invoke word2pdf-custom 57 | ``` 58 | 59 | 注意：`DISABLE_BIND_MOUNT_TMP_DIR=true` 环境变量主要是让 fun 不往 container 里挂载 /tmp 目录，因为 libreoffice 有个已知的问题，如果 /tmp 是 bind mount 的会直接退出，没有任何报错。 60 | 61 | ## 同步文件到 NAS 62 | 63 | 同步本地 NAS 目录 .fun/nas/auto-default/libreoffice/ 下的文件到 NAS 网盘 64 | 65 | ```bash 66 | $ fun nas sync 67 | ``` 68 | 69 | ## 部署 70 | 71 | 经过测试 libreoffice 在 MacOS 本地 Docker 环境里无法运行，可能和 Linux 的 kernel 版本有关，所以本例跳过了 fun local invoke，直接 deploy 到云端运行。 72 | 73 | ```bash 74 | $ fun deploy 75 | ``` 76 | 77 | ##
