             Summary: Speed up the kubernetes.feature
                 Key: MINIFICPP-1765
                 URL: https://issues.apache.org/jira/browse/MINIFICPP-1765
             Project: Apache NiFi MiNiFi C++
          Issue Type: Improvement
            Reporter: Ferenc Gerlits


Currently, each Scenario of the {{kubernetes.feature}} creates a new {{kind}} cluster during setup, and deletes it on teardown.  Every time {{kind create cluster}} runs, it takes 20 to 30 seconds.  Downloading the {{kind}} binary and loading the {{minifi}} docker image into the cluster each take around 5 seconds, as well.

Restructure the test setups to create and delete the kind cluster on feature level instead of test scenario level.  We could set up a single kind cluster on feature level, do a cleanup after every scenario, and only delete the cluster after all the test scenarios in the feature are finished.

One difficulty is that the volumes of the {{kind}} cluster are connected to the temporary test directories which are created for each Scenario.  We would need to either reconnect the volumes (if that is possible), or create feature-level temporary directories, copy the minifi {{config.yml}} etc to these new directories, and clean them up after the Scenario is done.
