-----------------------------------
Summary: Process refreshable-service-parameters.xml in Knox
Key: KNOX-2160
URL: https://issues.apache.org/jira/browse/KNOX-2160
Project: Apache Knox
Issue Type: New Feature
Components: Server
Affects Versions: 1.3.0, 1.2.0, 1.1.0
Reporter: Sandor Molnar
Assignee: Sandor Molnar
Fix For: 1.4.0
It'd be beneficial if there was a way to update service parameters in a
descriptor without using the Admin API/UI. The preferred approach is similar to
{{gateway-reloadable.xml}} handling. I'd add 2 new configurations:
- {{refreshable.service.parameters.folder}} - optional configuration to
indicate if Knox should monitor the given folder for service parameter changes.
If it's {{null}} -> no monitoring is enabled.
- {{refreshable.service.parameters.folder.monitor.interval}} - indicates the
time period Knox checks if any parameter changes were made; defaults to 60
seconds. This is relevant only if {{refreshable.service.parameters.folder}} is
{{not null}}.
A new monitor would be implemented (triggered only if monitoring is enabled) as
follows:
# checks {{refreshable-service-parameters.xml}} within the configured
{{refreshable.service.parameters.folder}}. The relevant configuration's name is
{{refreshable.service.parameters}}.
# if there is new content (based on file timestamp) -> parse the file and
build a new parameter list -> trigger topology redeployment with the new
parameter list by rewriting the appropriate descriptor file.
