问题

如果你想保证自己服务镜像足够小，那就要保证保证基础镜像尽量干净，但是这又会出现另一个问题，启动的容器内经常会遇到工具缺失的问题，需要手动安装。

这不，今天自己就遇到了。在新启动的容器内使用 mongo 命令连接数据库的时候，遇到了如下报错：

Command 'mongo' not found, but can be installed with:

apt install mongodb-clients

类似问题的报错截图如下：

解决

解决这个问题也非常简单，只需要安装 mongodb 客户端即可。但是需要注意当前系统类型，使用正确的包管理工具，本机安装命令如下：

apt install mongodb-clients

或者

apt-get install mongodb-clients 

执行过程如下：

过程截图如下：

安装成功后，我们执行刚才的数据库连接命令：

mongo 127.0.0.1:27017 

哈哈，连接成功了。
