If ISTIO enabled , data loading init job does not exit #12

Closed planetf1 closed 3 years ago

planetf1 commented 5 years ago

If istio is enabled in the vdc charts, the init* jobs will have an additional istio proxy. However this proxy will be running & not exit when for example the postgres data loading has completed.

There is some discussion of the relationship between sidecars such as istio & jobs at https://github.com/istio/istio/issues/6324

For now mitigation is to disable istio (which isn't yet default in any case) However istio is needed even in jobs as it will monitor & permit/deny traffic between the pods.

Many people have hit this issue - not just with istio, but other sidecars. This is now being designed to go into base kubernetes, probably 1.16. Initial discussion was in https://github.com/kubernetes/kubernetes/issues/25908 but See https://github.com/kubernetes/enhancements/issues/753 for the proposed implementation

Note the tail end of the discussion 'Please keep in mind, this KEP is very important for Istio !

It's a show stopper for all projects using service frameworks with coordinated bootstrap/shutdown (akka cluster, lagom etc.) together with istio service mesh'

The VDC environment will need significant re-work to adapt to the many changes made in Egeria to better support metadata integration. Additionally the helm charts used for the lab & a simple base config have evolved to better support different types of services, exposing of ports, persistent storage etc.

As such specific incremental changes to the current - now old - charts do not really add value.

As such closing for now
