问题描述
当我运行:COMPOSE_PROJECT_NAME=zk_test docker-compose up
时,出现错误提示
When I ran: COMPOSE_PROJECT_NAME=zk_test docker-compose up
, I got error saying
错误:在文件'./docker-compose.yml'中,服务必须是映射,而不是一个无类型.".
这是我的 yml 文件:
This is my yml file:
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_MY_ID: 2
ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
zoo3:
image: zookeeper
restart: always
container_name: zoo3
ports:
- "2183:2181"
environment:
ZOO_MY_ID: 3
ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

推荐答案
YAML 依赖于缩进.这个
YAML is indentation dependent. This
services:
zoo1:
是一个包含两个键的映射,它们都映射到 null
(即 Python 中的 None
).
is a mapping with two keys that both map to null
(i.e. None
in Python).
鉴于:
services:
zoo1:
是嵌套在映射中的映射.键 'services' 具有与键 zoo1
的映射作为值(同样具有值 null
).
is a mapping nested in a mapping. The key 'services' has as value a mapping with key zoo1
(which again has a value null
).
