本文介绍了 Docker 在 openSUSE 环境下的详细安装过程,并尝试运行一个简单 Spring Boot 的 image 来感受下 Docker 的风采。
什么是 Docker
Docker 是为开发人员和系统管理员用于构建、发布、并运行分布式应用程序的开放式平台。该平台由 Docker 引擎(一个便携、轻巧的运行时和打包工具) 和 Docker Hub (一个共享应用程序和自动化工作流的云服务)等组成。Docker 可以使应用程序从组件迅速组装并消除了开发、质量保证和生产环境之间的摩擦问题。这样一来,IT部门可以更快地发布,而这些应用程序不管是运行在笔记本电脑、数据中心的虚拟机,还是任何的云,其运行过程和结果都是一致的。
更多有关 Docker 的介绍,可以参阅《简述 Docker》 一文。

前置条件
64-bit 系统
kernel 3.10+
openSUSE 13.2+。本例使用的是 openSUSE Leap 42.1(如果你没有 openSUSE 系统,可以尝试在虚拟机里面装个 openSUSE 系统,可以参阅《Oracle VM VirtualBox 安装和使用》《CentOS 7 安装、配置》)
Oracle VM VirtualBox 安装和使用
https://waylau.com/about-oracle-vm-virtualbox/
CentOS 7 安装、配置
https://waylau.com/centos-7-installation-and-configuration/
使用 uname -r 检查 kernel 版本
$ uname -r
4.1.12-1-default
建议你使用最新的系统,以为一直的 bug 都会在新的 kernel 发布中修复。
安装
openSUSE 13.2 起,自带了仓库,所以无需添加
安装 openSUSE 国内镜像源
网络原因,访问 openSUSE 速度慢且不稳定,建议采用国内镜像库,下面例子是使用的 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:
linux-aihn:~ # zypper in docker

Accepting packages with wrong checksums can lead to a corrupted system and in extreme cases even to a system compromise.
However if you made certain that the file with checksum 'a6be..' is secure, correct
and should be used within this operation, enter the first 4 characters of the checksum
to unblock using this file on your own risk. Empty input will discard the file.

启动 docker 守护进程
$ sudo systemctl start docker.service
配置让 docker 服务随系统自动启动
$ sudo systemctl enable docker.service
docker 会创建一个以docker命名的用户组,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
上述命令不会卸载 images、containers、volumes, 或者用户创建在主机的配置文件。若想卸载干净上述所有 images、containers、volumes, 执行:
$ rm -rf /var/lib/docker
用户创建在主机的配置文件需手动删除。
拉取 image 到本地
可以将 Docker Bub 存储的 image 拉取到本地,执行
docker pull waylau/docker-spring-boot
输出如下:
linux-aihn:~ # docker pull waylau/docker-spring-boot

执行:
docker run -p 8080:8080 -t waylau/docker-spring-boot
