I am using the Openshift resource ImageStream to to pull latest images from our external image repository for our test environments so when a new image is built for an application it gets rolled out automatically when ImageStream identifies a new image available.
importPolicy:
scheduled: true
Currently it seems to have a cluster wide refresh interval of 15 minutes according to Openshift 4.13 docs
This command causes OpenShift Container Platform to periodically update this particular image stream tag. This period is a cluster-wide setting set to 15 minutes by default.
How can i reduce this interval to for example 5 minutes?
Is there any performance issue reducing this refreshing interval?
Openshift version: 4.13
Unfortunately, there is no way to change this default value in OpenShift 4.x so far. So, if you need to re-import your image more frequently, you could manually re-import the image with a CronJob or a script you implement.
