C++ 程序员日常开发中不可避免地遇到变更电脑，变更服务器等事件时重建搭建 C ++ 开发环境切实过于沉重，须要消耗很多不必要的宝贵时间。vim 的 YouCompleteMe(简称 YCM) 插件能够实现较好的 C /C++ 语言主动补全跳转性能，是利用 vim 进行 C /C++ 代码编辑的必备神器之一。而后理论中 YCM 的装置及其简单，不仅依赖 python 动态链接库，还依赖特定高版本的 gcc 和 clang 或 clangd 和 cmake 等。筹备这些前置组件也很费时费力。有鉴于此，本文介绍一种新的玩法，并给出实际操作细节和间接可用的 docker 镜像成绩，即：构建基于 Vim 的 C ++ 补全跳转插件 YouCompleteMe 的 Docker 镜像，一键实现任意机器上 C ++ 开发环境搭建。具体操作办法介绍如下。
环境筹备
工夫：2021-03-24
机器配置：CentOS Linux release 7.5.1804 (Core)，8 核 12G
创立根底的 docker 镜像
思考装置以后工夫下最新版本的 vim 和 YoucompleteMe 插件。参考 YouCompleteMe 官网介绍的装置办法要求 vim/gcc/clang/clangd/cmake/python 都在比拟高的版本下能力装置胜利。而咱们为了制作 docker 镜像，因而不可能选很旧的根底 os。参考 YCM 官网的倡议，咱们根底 OS 抉择 ubuntu 20.04 LTS。hub.docker.com 上间接现成的镜像文件。配置文件须要筹备好如下 3 个配置文件，本文间接贴出原文内容如下：

最初是 Dockerfile 编写如下：

CMD vim将以上 4 个文件搁置一个目录下，在任意一台装置了 docker 的 x86_64 机器上该目录下执行命令：
docker build --no-cache -t ycm-base:1.0 即可创立一个本地 docker 镜像名为：ycm-base:1.0
本文作者曾经按如上步骤创立好了一个可用的 ycm 根底镜像，并上传到了 hub.docker.com 名为：apollo008/vim8-ycm:3.0。地址是：https://hub.docker.com/repository/docker/apollo008/vim8-ycm-customize-user 读者可间接通过 docker 命令：docker pull apollo008/vim8-ycm:3.0 下载该镜像到本地应用即可。
创立定制用户的 docker 镜像
以上 docker 镜像创立的是 root 用户的。如果应用 root 账户登录进入 docker 容器中编辑文件后，必然是 root 用户所有，导致容器外其余用户没有权限编辑或浏览该文件。解决得方法是才上述根底 vim-ycm 镜像的根底上，用户本人在本地 docker 环境中迅速创立一个应用本人用户名（尤其是 uid）的账户的 ycm docker 镜像，而后本地以该特定用户拜访该 docker 容器即可。之所以分成两个容器，是因为根底容器制作费时，切可能依赖外网，导致装置难以胜利，所以制作好上传至公共镜像仓库，不同用户在即镜像根底上定制一下本人的特定 uid 和 username 的本地镜像即可，操作步骤如下。
Dockerfile 内容如下：

CMD vim该 docker 镜像内置的 vim8.1 和 ycm 是 ubuntu 20.04 LTS 截至目前 2021.03.22 最新版的 vim 和 ycm。~/.vimrc 中相应的配置都已欠缺，包含较为正当好看的配色计划。成果如下图。
本镜像用法是：在本地执行如下命令 创立本人用户名比方 work/user 等的 docker 镜像。
docker build –no-cache -t myycm:latest –build-arg APP_USER=work –build-arg APP_GROUP=work –build-arg APP_UID=1000 –build-arg APP_GID=1001 .
镜像生成后举荐用法是：docker run -itd –name ycm1 -v hostPath:InDockerPath myycm:latest /bin/bash
docker exec -it ycm1 /bin/bash 而后在 docker 容器内的交互 bash 上执行 vim xxx.cpp 编辑文件。防止频繁关上 docker container 相应速度慢。
