Hi,
We are opinionated about which Flink image we would like the Flink Kubernetes
operator to use. So in the flink-kubenetes-operator the ReconciliationUtils
prior to [1] we are patching in code to trigger the update of the
FlinkDeployment resource if needed with a new Flink image from an environment
variable.
We would like to avoid needing to patch the code, so are thinking that the way
to do this would be to have a new discover pattern to bring in our code from
the plugins folder in a similar way to ListenerUtils[2], that would allow us to
force an update of the Flink Deployment with something like:
forceReconcilers= ReconciliationUtils.discoverForceReconcilers(configManager);
for ( ForceReconciler forceReconciler: forceReconcilers) {
If (forceReconciler.shouldForceUpdate(current)) {
updateControl = UpdateControl.updateResource(current);
}
}
Just before [1].
This would allow us to supply code as a plugin that would test our environment
variable and see if we need to force an update of the deployment.
I am happy to code this ,
Kind regards, David.
