Kubernetes and Docker compatibility
Kubernetes 1.14 validates Docker Engine versions up to 18.09
(the latest version when Kubernetes 1.14 was released)Kubernetes 1.13 only validates Docker Engine versions up to 18.06
Is this a problem if I use Kubernetes with a "too recent" Docker Engine?
No!
"Validates" = continuous integration builds with very extensive (and expensive) testing
The Docker API is versioned, and offers strong backward-compatibility
(If a client uses e.g. API v1.25, the Docker Engine will keep behaving the same way)
