opencast的docker安装

在之前的从源安装和从包安装opencast，都遇到较多环境问题导致失败。所有采用docker安装。

Dockers是有能力打包应用程序及其虚拟容器，可以在任何Linux服务器上运行的依赖性工具，这有助于实现灵活性和便携性，应用程序在任何地方都可以运行。

docker安装opencast总结：

1 安装docker。参考https://docs.docker.com/install/linux/docker-ce/ubuntu/

2 安装docker-compose。参考https://docs.docker.com/install/linux/docker-ce/ubuntu/

3 下载.yml文件。

（下载失败，自己vi文件，然后将内容写入，内容参照：https://github.com/opencast/opencast-docker/tree/master/docker-compose）

vi docker-compose.allinone.mariadb.yml
