今天就跟大家聊聊有關Docker怎么在openSUSE 下的安裝、使用,可能很多人都不太了解,為了讓大家更加了解,小編給大家總結了以下內容,希望大家根據這篇文章可以有所收獲。
Docker 在 openSUSE 環境下的詳細安裝過程,并嘗試運行一個簡單 Spring Boot 的 image 來感受下 Docker 的風采。
Docker 是為開發人員和系統管理員用于構建、發布、并運行分布式應用程序的開放式平臺。該平臺由 Docker 引擎(一個便攜、輕巧的運行時和打包工具) 和 Docker Hub (一個共享應用程序和自動化工作流的云服務)等組成。Docker 可以使應用程序從組件迅速組裝并消除了開發、質量保證和生產環境之間的摩擦問題。這樣一來,IT部門可以更快地發布,而這些應用程序不管是運行在筆記本電腦、數據中心的虛擬機,還是任何的云,其運行過程和結果都是一致的。
更多有關 Docker 的介紹,可以參閱《簡述 Docker》 一文。
64-bit 系統
kernel 3.10+
openSUSE 13.2+。本例使用的是 openSUSE Leap 42.1(如果你沒有 openSUSE 系統,可以嘗試在虛擬機里面裝個 openSUSE 系統,可以參閱《Oracle VM VirtualBox 安裝和使用》《CentOS 7 安裝、配置》)
使用 uname -r
檢查 kernel 版本
$ uname -r 4.1.12-1-default
建議你使用最新的系統,以為一直的 bug 都會在新的 kernel 發布中修復。
openSUSE 13.2 起,自帶了倉庫,所以無需添加
網絡原因,訪問 openSUSE 速度慢且不穩定,建議采用國內鏡像庫,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
$ sudo zypper in docker
輸出如下:

$ sudo systemctl start docker.service
$ sudo systemctl enable docker.service
docker 會創建一個以docker
命名的用戶組,添加用戶到這個用戶組
sudo /usr/sbin/usermod -a -G docker <username>
卸載 Docker 包:
$ sudo zypper rm docker
上述命令不會卸載 images、containers、volumes, 或者用戶創建在主機的配置文件。若想卸載干凈上述所有 images、containers、volumes, 執行:
$ rm -rf /var/lib/docker
用戶創建在主機的配置文件需手動刪除。
可以將 Docker Bub 存儲的 image 拉取到本地,執行
docker pull waylau/docker-spring-boot
輸出如下:

Important: This registry version will not be supported in future versions of docker.
執行:
docker run -p 8080:8080 -t waylau/docker-spring-boot
