 </tr>

## 查看版本 ##

## 详细信息 ##

## Docker Search ##

搜索 Docker hub 中的 nginx 镜像

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 </pre></td> 
 <td><pre>docker search nginx </pre></td> 
 </tr> 
 </tbody> 
</table>

## Docker pull ##

多个层级每一层分别下载

![ARtaHP.png][]

## docker images ##

last表示时最新的

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 2 3 4 5 6 </pre></td> 
 <td><pre>[root@localhost docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest 2bcb04bdb83f 9 days ago 109MB [root@localhost docker]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest 2bcb04bdb83f 9 days ago 109MB </pre></td> 
 </tr> 
 </tbody> 
</table>

## docker 卸载镜像 ##

## Docker 创建一个容器 ##

<table> 
 <tbody>

### Redis ###

即使本地没有Redis的镜像我们依然可以安装。

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 </pre></td> 
 <td><pre>docker run --name Redis -d redis:4-alpine </pre></td> 
 </tr> 
 </tbody> 
</table>

进入终端

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 </pre></td> 
 <td><pre>docker exec -it kvsotre /bin/sh #进入容器中 </pre></td> 
 </tr> 
 </tbody> 
</table>

## 查看日志 ##

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 </pre></td> 
 <td><pre>docker logs kvstore #产看kvstore的日志 </pre></td> 
 </tr> 
 </tbody> 
</table>

## 镜像生成途径 ##

### 基于容器 ###

1.创建一个busybox的容器

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 2 3 4 </pre></td> 
 <td><pre>[root@localhost ~]# docker run --name b1 -it busybox / # mkdir -p /data/html / # vi /data/html/index.html &lt;h1&gt;Busybox httpd Server &lt;/h1&gt; </pre></td> 
 </tr> 
 </tbody> 
</table>

![ARIFLn.png][]

为了引用方便我们可以给镜像打上标签.

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 2 3 4 5 </pre></td> 
 <td><pre>[root@localhost ~]# docker tag --help Usage: docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG] Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE </pre></td> 
 </tr> 
 </tbody> 
</table>

![ARIz01.png][]

![ARo2Ax.png][]

![ARTFU0.png][]

docker运行镜像生成了原先保存的镜像文件。

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 </pre></td> 
 <td><pre>docker commit -a "bigdataxiaohan &lt;467008580@qq.com&gt;" -c 'CMD ["/bin/httpd","-f","-h","/data/html"]' -p t1 hphblog/httpd:v0.2 </pre></td> 
 </tr> 
 </tbody> 
</table>

![ARTsG8.png][]

启动基于v0.2版本的服务

![ART2rj.png][]

![ARTfZn.png][]

dcoker服务可以直接访问。

由于将docker镜像推导Docker hub 需要相同的组织类名 而我在DockerHub 上创建的仓库为bigdataxiaohan/httpd 我们把镜像更改以下名称

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 </pre></td> 
 <td><pre>docker tag hphblog/httpd:v0.2 bigdataxiaohan/httd:v0.2 </pre></td> 
 </tr> 
 </tbody> 
</table>

然后登录

![AR7wy4.png][]

网络不是很好建议多尝试几次。

<table> 
 <tbody> 
 <tr> 
 <td><pre>1 </pre></td> 
 <td><pre>docker tag hphblog/httpd:v0.2 bigdataxiaohan/httpd:v0.2 </pre></td> 
 </tr> 
 </tbody> 
</table>

(⊙﹏⊙) 还是放弃吧 我们可以使用腾讯云的Docker镜像仓库

哎呀妈呀QAQ 终于push成功了

 <td><pre>1 2 3 4 5 6 7 8 </pre></td> 
 <td><pre>[root@localhost ~]# docker save --help Usage: docker save [OPTIONS] IMAGE [IMAGE...] Save one or more images to a tar archive (streamed to STDOUT by default) Options: -o, --output string Write to a file, instead of STDOUT </pre></td> 
 </tr> 
 </tbody> 
</table>
