[英]docker-compose.yml file errors on running docker-compose up
Here is my docker-compose.yml file: 这是我的docker-compose.yml文件:
version:'2':
services:
redis:
image: redis
environment:
- HOST='localhost'
- PORT=6379
ports:
-"0.0.0.0:${PORT}:6379"
I get this error on running docker-compose up: 我在运行docker-compose时出现此错误:
ERROR: The Compose file './docker-compose.yml' is invalid because:
Invalid service name 'services' - only [a-zA-Z0-9\._\-] characters are allowed
Unsupported config option for services: 'redis'
There are multiple problems with your file. 您的文件存在多个问题。 The one causing the syntax error is that you have an extra colon on the first line:
导致语法错误的是您在第一行有一个额外的冒号:
version:'2':
that way you define a scalar string key version:'2'
with value of null
. 这样你就可以定义一个标量字符串键
version:'2'
,其值为null
。 Since you are therefore not defining the version
of the docker compose file, the rest of the file (which is version 2 oriented) fails. 因为您没有定义docker compose文件的
version
,所以文件的其余部分(面向版本2)将失败。 This is best resolved by adding a space after version:
通过在
version:
之后添加空格可以最好地解决此问题version:
In addition your ports
definition is incorrect, the value for that should be a sequence
/ list
, and you again specify a scalar string -"0.0.0.0:${PORT}:6379"
because there is no space after the initial dash. 此外,您的
ports
定义不正确,其值应为sequence
/ list
,并再次指定标量字符串-"0.0.0.0:${PORT}:6379"
因为初始短划线后没有空格。
Change your docker_compose.yaml
file to: 将
docker_compose.yaml
文件更改为:
version: '2'
# ^ no colon here
# ^ space here
services:
redis:
image: redis
environment:
- HOST='localhost'
- PORT=6379
ports:
- "0.0.0.0:${PORT}:6379"
# ^ extra space here
just remove last character ":" into string version:'2':
只需将最后一个字符“:”删除为字符串
version:'2':
after it docker-compose.yml
must be like 之后它
docker-compose.yml
必须像
version:'2'
services:
redis:
image: redis
environment:
- HOST='localhost'
- PORT=6379
ports:
-"0.0.0.0:${PORT}:6379"
