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：

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：

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。
