In my experience, very, but it’s also not magic. Being able to package an application with its environment and ship it to any machine that can run Docker is great but it doesn’t solve the fact that modern deployment architecture can become extremely complicated, and Docker adds another component that needs configuration and debugging to an already complicated stack.
Definitely looks better imo. The new lighting changes make it much more atmospheric, and I feel like heroes are easier to pick out against the terrain as well.
