My guess: indentation errors. Try:

version: '2'

services:
  javaclient:
    build: .
  redis:
    image: redis
    container_name: redisdb

thanks!!!

I had the same problem and it didn’t work for me until I added a blank line to to top of my .yml file.

The error in your YAML file could be due to the incorrect usage of the single quote in the version declaration (version: '2’). Specifically, the closing quote seems to be a right single quotation mark (’), instead of a standard single quote ('). This can cause YAML to throw an error.
