0x00 前言

有好多时候需要搭建一个 Demo 为同事或其他人演示一些应用程序，如果在服务器上新建一套比如 Owncoud Nextcloud 之类的软件，对于有些有软件洁癖的人来说是一个痛苦，用完了还得删除，不弄的话又没有好的演示环境。这时候用 Snap 和 Docker 就再合适不过了，今天我在这里为大家演示的是在 Centos7 上面添加 Snap 的安装环境来演示。Snap 官放默认的支持发型版本有以下这些，Centos 不在其中
* Arch Linux* Debian* Deepin* Elementary OS* Fedora* GalliumOS* KDE Neon* Kubuntu* Linux Mint* Lubuntu* Manjaro Linux* openSUSE* Parrot Security OS* Raspbian* Solus* Ubuntu* Xubuntu* Zorin OS
