docker-compose安装zookeeper报错

[root@localhost docker_zk]# docker-compose up -d
ERROR: The Compose file ‘./docker-compose.yml’ is invalid because:
Unsupported config option for services.zk: ‘images’

image 写成 images

修复docker-compose.yml后的配置信息如下：

version: '3.1'
services:
  zk:
    image: daocloud.io/daocloud/zookeeper:latest
    restart: always
    container_name: zk
    ports:
      - 2181:2181
