When is Docker a good fit?

Question

Compare suitability, operational responsibilities and limits before choosing this technology for a project. Which trade-offs should guide the decision?

Tasadduq Burney · Accepted Answer

Docker is useful for packaging an application with its runtime dependencies and running the same image across environments. Containers share the host kernel and are not full virtual machines. Keep persistent state outside the disposable container filesystem and treat the image as an immutable artifact.
