In this lab session we are going to fix the error - "ERROR: Version in "./docker-compose.yml" is invalid. 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.
"
This is the most common issue when you specify the different version numbers in your docker-compose.yml but docker expects you to specify a higher or correct version.
