istio-pilot may skip event handlers when deployed with the Charmed Kubeflow bundle #113

Closed DnPlas closed 1 year ago

DnPlas commented 2 years ago

Behaviour

When deployed in a large bundle with multiple charms related to it (like the Charmed Kubeflow bundle), istio-pilot may skip the method that sends gateway-info to remote units and/or the handler for the default gateway, which causes the following:

1) If the handle_default_gateway is not called, the default-gateway never gets created. 2) If the handle_gateway_info_relation is not called, related remove units will never get the gateway info, which prevents them to complete their start up.

Note that even though this is wrong behaviour, istio-pilot will not fail.

Workarounds

For 1): juju run --unit istio-pilot/0 -- "export JUJU_DISPATCH_PATH=hooks/config-changed; ./dispatch"

For 2) This behaviour should be corrected by this change

This issue is still seen. Need to address it in Istio Event Handling epic.
