本文先容了 Docker 在 openSUSE 情况下的具体安装进程,并实验运行一个简朴 Spring Boot 的 image 来感觉下 Docker 的风范。

什么是 Docker

Docker 是为开拓人员和系统打点员用于构建、宣布、并运行漫衍式应用措施的开放式平台。该平台由 Docker 引擎(一个便携、轻巧的运行时和打包东西) 和 Docker Hub (一个共享应用措施和自动化事情流的云处事)等构成。Docker 可以使应用措施从组件迅速组装并消除了开拓、质量担保和出产情况之间的摩擦问题。这样一来,IT部分可以更快地宣布,而这些应用措施不管是运行在条记本电脑、数据中心的虚拟机,照旧任何的云,其运行进程和功效都是一致的。

更多有关 Docker 的先容,可以参阅《简述 Docker》 一文。

前置条件

  • 64-bit 系统
  • kernel 3.10+
  • openSUSE 13.2+。本例利用的是 openSUSE Leap 42.1(假如你没有 openSUSE 系统,可以实验在虚拟机内里装个 openSUSE 系统,可以参阅《Oracle VM VirtualBox 安装和利用》《CentOS 7 安装、设置》)
  • 利用 uname -r 查抄 kernel 版本

    $ uname -r
    4.1.12-1-default

    发起你利用最新的系统,软件开发,软件开发,觉得一直的 bug 城市在新的 kernel 宣布中修复。

    安装

    openSUSE 13.2 起,自带了客栈,所以无需添加

    安装 openSUSE 海内镜像源

    网络原因,会见 openSUSE 速度慢且不不变,发起回收海内镜像库,下面例子是利用的 aliyun

    zypper addrepo -f http://mirrors.aliyun.com/opensuse/update/leap/42.1/oss  openSUSE-42.1-Update-Oss
    
    zypper addrepo -f http://mirrors.aliyun.com/opensuse/update/leap/42.1/non-oss/ openSUSE-42.1-Update-Non-Oss
    
    zypper addrepo -f http://mirrors.aliyun.com/opensuse/distribution/leap/42.1/repo/oss/ openSUSE-42.1-Oss
    
    zypper addrepo -f http://mirrors.aliyun.com/opensuse/distribution/leap/42.1/repo/non-oss/  openSUSE-42.1-Non-Oss
    
    zypper addrepo -f http://mirrors.aliyun.com/packman/openSUSE_Leap_42.1/ aliyun-packman

    安装 Docker 包

    $ sudo zypper in docker

    输出如下:

    启动 docker 守护历程

    $ sudo systemctl start docker.service

    设置让 docker 处事随系统自动启动

    $ sudo systemctl enable docker.service

    docker 会建设一个以docker定名的用户组,添加用户到这个用户组

    sudo /usr/sbin/usermod -a -G docker <username>

    卸载 docker

    卸载 Docker 包:

    $ sudo zypper rm docker
