一、Etherpad介绍

1.Etherpad简介

Etherpad是一个高度可定制的开源在线编辑器，提供真正实时的协作编辑。

2.Etherpad特点

Etherpad 允许您实时协作编辑文档，就像在浏览器中运行的实时多人编辑器一样。与您的朋友、同学或同事一起撰写文章、新闻稿、待办事项等，所有这些都在同一时间处理同一个文档。

二、检查本地docker服务状态


[root@docker ~]# systemctl status docker

四、部署Etherpad容器

1.创建数据目录

[root@docker ~]# mkdir -p /data/etherpad
[root@docker ~]# cd /data/etherpad/
[root@docker etherpad]# ls

2.目录授权

需要指定挂载目录权限，个人或测试环境可授予完全权限。

chmod -R 777 /data/etherpad/

3.创建Etherpad容器

[root@docker etherpad]# docker run -d --name etherpad --restart always -p 9001:9001 -v /data/etherpad/data:/opt/etherpad-lite/var etherpad/etherpad:latest
d1ad595bda8babddd108d3932f02c167e3bb0ef57c121ab55a1186e4c147305e

4.查看Etherpad容器状态


[root@docker etherpad]# docker ps -a
CONTAINER ID   IMAGE                      COMMAND                  CREATED         STATUS                            PORTS                                       NAMES
