Docker Action 記錄 作者: LinkSystem 2017/08/11

Docker Action 是我關(guān)于Docker-CE的實踐記錄，該實踐的構(gòu)建環(huán)境以下：

[root@core ~]# cat /etc/redhat-release 
CentOS Linux release 7.3.1611 (Core) 

[root@core ~]# docker version
Client:
 Version:      17.07.0-ce-rc2
 API version:  1.31
 Go version:   go1.8.3
 Git commit:   36ce605
 Built:        Mon Aug  7 23:43:46 2017
 OS/Arch:      linux/amd64

Server:
 Version:      17.07.0-ce-rc2
 API version:  1.31 (minimum version 1.12)
 Go version:   go1.8.3
 Git commit:   36ce605
 Built:        Mon Aug  7 23:45:07 2017
 OS/Arch:      linux/amd64
 Experimental: false

配置Yum源

# yum-utils的作用是添加 repo 文件
[root@core ~]# sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# 注意速度有點慢
[root@core ~]# sudo yum-config-manager 
>     --add-repo 
>     https://download.docker.com/linux/centos/docker-ce.repo
# 開啟指定部分 repo
[root@core ~]# sudo yum-config-manager --enable docker-ce-edge
[root@core ~]# sudo yum-config-manager --enable docker-ce-test
# 更新緩存
[root@core ~]# sudo yum makecache fast

部署 Docker-CE

[root@core ~]# sudo yum install docker-ce

# 指定版本
# [root@core ~]# yum list docker-ce.x86_64  --showduplicates | sort -r
# sudo yum install docker-ce-

本地部署

# RPM下載地址： https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
# 注意：Docker-CE 的依賴可以使用國內(nèi) Yum 源， 我配置的是阿里云的源
[root@core ~]# sudo yum install docker-ce/docker-ce-17.07.0.ce-0.2.rc2.el7.centos.x86_64.rpm

配置 Docker-CE

[root@core ~]# sudo systemctl start   docker
[root@core ~]# sudo systemctl enable  docker
# 配置 Docker 加速器
[root@core ~]# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://df98fb04.m.daocloud.io
[root@core ~]# sudo systemctl restart docker

測試

[root@core ~]# sudo docker run hello-world
Unable to find image "hello-world:latest" locally
latest: Pulling from library/hello-world
b04784fba78d: Pull complete 
Digest: sha256:9a4ec8dac439d00fff31bf41b23902bfd7f7465d4b4c8c950e572e7392f33c66
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

部署腳本

[root@core ~]# curl -fsSL get.docker.com -o get-docker.sh
[root@core ~]# sudo sh get-docker.sh

卸載 Docker-CE

# Docker 舊版本
[root@core ~]# sudo yum remove docker 
>                   docker-common 
>                   docker-selinux 
>                   docker-engine
# Docker-CE 版本
[root@core ~]# sudo yum remove docker-ce
[root@core ~]# sudo rm -rf /var/lib/docker
