下载完之后我们通过该镜像启动一个容器</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code98096">
<br>
docker run -d -p 5000:5000 --privileged=true -v /opt/registry:/tmp/registry registry</div>
<p>
</p>
<p>
参数说明：</p>
<ul>
<li>
-v /opt/registry:/tmp/registry :默认情况下，会将仓库存放于容器内的/tmp/registry目录下，指定本地目录挂载到容器</li>
<li>
–privileged=true ：CentOS7中的安全模块selinux把权限禁掉了，参数给容器加特权，不加上传镜像会报权限错误(OSError: Permission denied: ‘/tmp/registry/repositories/liibrary')或者（Received unexpected HTTP status: 500 Internal Server Error）错误</li>
</ul>
<p>
<strong>客户端上传镜像</strong></p>
<p>
修改/etc/sysconfig/docker（Ubuntu下配置文件地址为：/etc/init/docker.conf），增加启动选项(已有参数的在后面追加)，之后重启docker，不添加报错，https证书问题。</p>
