执行docker-compose config
时出现以下错误:
Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/
因此,根据错误消息,我尝试使用版本2.2
和3.3
两者都导致相同的错误消息
ERROR: The Compose file './docker-compose.yml' is invalid because:
services.docker-mongo.image contains an invalid type, it should be a string
答案 0 :(得分:0)
错误消息是自解释的,您的docker-compose应该如下所示:
version: '3.7'
services:
docker-mongo:
image: mongo:4.2.1
ports:
- "27017:27017"
networks:
- mynetwork
networks:
