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.
