Docker快速部署ownCloud
Jan. 27, 2017如前（Owncloud安装过程）所述，ownCloud安装涉及LAMP环境的搭建与调试，耗时比较长，本文介绍通过Docker快速部署ownCloud
安装Docker
Ubuntu：sudo apt-get install docker.ioCentOS：
yum install docker.io
systemctl start docker
docker安装好后，基本上就可以直接开启下一步了，但是从Docker Hub拉取镜像非常慢，建议到Daocloud.io用个加速器。
部署
拉取ownCloud官方镜像
ownCloud的官方镜像页面：https://hub.docker.com/_/owncloud/这个镜像已经集成了Apache+PHP环境
拉取：
docker pull owncloud
fikgreg@ubuntu:~$ sudo docker pull owncloud

如果你不是用root账户登录的话，很可能发生错误：
Warning: failed to get default registry endpoint from daemon (Cannot connect to the Docker daemon. Is the docker daemon running on this host?). Using system default: https://index.docker.io/v1/ Cannot connect to the Docker daemon. Is the docker daemon running on this host?
在前面加上sudo获取root权限就好了······（之前被这个问题搞了好几次）
sudo docker pull owncloud
sudo docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
owncloud 9.1 2e5636e065e8 2 days ago 566.1 MB
启动镜像
启用8.1版本sudo docker run -d -p 80:80 owncloud:8.1
或者启用最新的9.1版本
fikgreg@ubuntu:~$ sudo docker run -d -p 80:80 owncloud:9.1

在浏览器里输入http://你的服务器ip
现在，直接设置用户名和密码，然后点击“安装完成“就可以使用ownCloud了，这样数据库使用的是SQLite。
P.S.
如果要使用MySQL作为数据库，那么你需要先运行一个MySQL容器，启动镜像的命令后加上--link my-mysql:mysql连接mysql容器创建MySQL容器
拉取：sudo docker pull mysql
