You are right. Normally in these spoofs Hitler reacts to some outside force shattering his dreams. The outside force usually being a corporation producing a movie or video game, the dreams shattered being his expectations of that movie or video game. In this instance he is just ridiculing his generals and I guess the general Docker community. If the meme was applied properly it would be Hitler himself who set up the Docker cluster, and the generals informing him of the ways it failed. His monologue would be about his own expectations of the greatness of Docker and how the Docker team or cgroups abstractions failed him. The difference is subtle, but it's definitely true that in this application Hitler is not ridiculed, which makes the whole bit more awkward and less funny.
