Kubernetes has deprecated Docker and plans to retire it in about a year, in version 1.22 or 1.23. This news caused many questions and misunderstandings. The Kubernetes blog has two whole articles that explain the meaning of the Changelog entry ( one and two ). To summarize everything, then for developers (those who are Dev ) nothing changes - they can still continue to use docker build to build their containers, but for the engineers responsible for operating the cluster ( Ops ), it's time to figure it out and learn a few new tools.
