the complete deploym
Flink Kubernetes Operator aims to capture the responsibilities of a human
operator who is managing Flink deployments. Human operators have deep knowledge
of how Flink deployments ought to behave, how to start clusters, how to deploy
jobs, how to upgrade them and how to react if there are problems. The main goal
of the operator is the automation of these activities, which cannot be achieved
through the Flink native integration alone.
