Only version 2.X of the docker-compose format is supported

[hrishin]

Description

https://github.com/fabric8io/docker-maven-plugin/blob/master/samples/docker-compose/src/main/docker/docker-compose.yml file is having following version number

version: "2"

When we run the example it logs following message
Only version 2.X of the docker-compose format is supported for xxx/docker-compose file

Is it desired behavior or bug?

Found a workaround. Set the version to "2.2" and it works for now.

@jthoenes do you mean set the version in 2.2 in the docker-compose.yml file or somewhere else?

[jthoenes]

@jimusbobus yes, exactly in the docker-compose.yml file
