Eamon Ford updated SDAP-259:
----------------------------
Status: In Progress (was: To Do)
> Collection Manager does not pick up Collections Config file updates with K8s
> ----------------------------------------------------------------------------
>
> Key: SDAP-259
> URL: https://issues.apache.org/jira/browse/SDAP-259
> Project: Apache Science Data Analytics Platform
> Issue Type: Bug
> Components: collection-ingester
> Reporter: Eamon Ford
> Assignee: Eamon Ford
> Priority: Major
>
> When the Collection Manager is deployed in kubernetes, the Collections Config
> exists as a k8s configmap which gets mounted in the Collection Manager as a
> file in a volume. However, when the configmap gets updated (by the Config
> Operator), the file mounted in the Collection Manager does not produce the
> expected "modified" Linux filesystem event, which the Collection Manager
> relies on. Instead, it produces a sequence of "created", "moved", "deleted"
> filesystem events which are a result of the way Kubernetes updates mounted
> configmaps.
>
> Since the Collection Manager should be agnostic to whether or not it's
> running inside Kubernetes, we should not change it to look for this
> Kubernetes-specific sequence of filesystem events as that would break the
> functionality when running outside of Kubernetes. Instead, the class that
> watches the Collections Config file for updates should be changed to just
> reload the file on a regular interval.
