四、部署etherpad镜像

下载etherpad镜像

docker pull etherpad/etherpad:latest

创建容器

完整创建过程：

1.使用docker-cli启动一个etherpad的容器。

docker run -d --name etherpad --restart always -p 3344:9001 -v /opt/etherpad/data:/opt/etherpad-lite/var etherpad/etherpad:latest

2.使用docker-compose启动一个etherpad的容器

version: '3.9'
services:
    etherpad:
        image: 'etherpad/etherpad:latest'
        volumes:
            - '/opt/etherpad/data:/opt/etherpad-lite/var'
        ports:
            - '3344:9001'
        restart: always
        container_name: etherpad


3.容器启动正常，访问
http://ip:3344

检查容器运行状态

root@WellDone:/home/goodjob# docker ps
CONTAINER ID   IMAGE                                                       COMMAND                   CREATED         STATUS         PORTS                                       NAMES
etherpad        etherpad/etherpad:latest                                           "docker-entrypoint.s…"   etherpad        40 seconds ago   Up 38 seconds (healthy)   0.0.0.0:3344->9001/tcp, :::3344->9001/tcp
