    • OOM-1505
      • Akansha Dua to see if there is an ability to list all schema validations at once for a chart
      • and to install all python libraries at once instead of one at a time
    • ISTIO vs NGINX
      • ISTIO sidecar injection problematic
      • ISTIO memory (and cpu) increase per Pod is a concern - want to reduce footprint not increase
      • ISTIO evolution is now complete. Based on results the decision has been to proceed with NGNIX as Ingress controller for El Alto
      • Lucjan Bryndza to work with Venkata Harish Kajur and Akansha Dua to ensure generation and validation of ingress is easily replaceable based on which ingress controller is deployed
      • need to prove out ingress based on DMaaP and DCAE cluster-to-cluster communication requirements
    • Staging vs Master
      • seems to be a disconnect in the community
      • all helm chart patches should be pushed to 'staging' and can include STAGING tags on images
      • some STAGING tags were pushed into 'master' and need to be flipped to released images
      • need to better socialize the restriction of ONLY released tags
      • Mike Elliott to help get back to stable state in both staging and master branches - both are currently "broken"

      NGINX is equivalent to Envoy.

      ISTIO is control plane for service mesh.  ISTIO by default uses Envoy as data plane (sidecar).  But, there are efforts in NGINX community to use NGINX as the data plane for ISTIO.

      Now coming to my question: Is the intention to use ISTIO control plane with NGINX sidecar?  Or are you suggesting to use something else for control plane?My request is to provide flexibility for people to use whichever sidecar they prefer, but standardizing on ISTIO control plane is good in my view.

        +1 on Srini's comment. BTW, Envoy is supported by Google – all the issues we are seeing now are only temporary.

        Thanks,

          Mike Elliott , I understand from your meeting minutes, somebody did comparison between Envoy and NGINX with respect to CPU and memory.  Can that be shared?
