当我跑:COMPOSE_PROJECT_NAME=zk_test docker-compose up
时,我收到错误说
“错误:在文件'./docker-compose.yml'中,服务必须是映射,而不是 a NoneType。“。
这是我的yml文件:
version: '2'
services:
zoo1:
image: zookeeper
restart: always
container_name: zoo1
ports:
- "2181:2181"
environment:
ZOO_MY_ID: 1
ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
zoo2:
image: zookeeper
restart: always
container_name: zoo2
ports:
- "2182:2181"
environment:

ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
zoo3:

YAML依赖于缩进。此
services:
zoo1:
是一个带有两个键的映射,它们都映射到null
(即Python中的None
)。
鉴于:
services:
zoo1:
是嵌套在映射中的映射。关键的服务'具有键zoo1
(具有值null
)的映射值。
