Users had reported that monitoring data hasn't been showing up in Cloud Monitoring. This seems to be due to incompatibility with the out-dated Istio version being used by this project. To resolve this, I updated to use the latest version of ASM, which should be more useful for demos

  • Updated Istio installation script to install ASM instead
  • updated resources that referenced istio service ids with the ASM counterpart ids
  • changed minimum node counts to align with ASM's expectation of 8 vCPU

I did my review, this LGTM, great job!

Disclaimer: I haven't tested this PR myself.

For a future PR, here are what could be done in addition/on top of that:

  • Use the ASM TF Module to remove the need of the asmcli bin
  • The Ingress Gateway, based on the above point will have its own dedicated installation manifests
  • Managed Data plane seems to be a good candidate too for the Cloud Ops sandbox in order to simplify the upgrade of the sidecar proxies by Google
  • Note: the frontend-external Service could also be removed from the manifests since the Ingress Gateway is the only Public IP needed.

@daniel-sanche, do you need to update the description of this PR to better reflect where you landed? I see some notes about WI but don't see anymore these changes as an example.

@mathieu-benoit Thanks for the feedback! I added your comments to the issue around terraform refactoring for next quarter.

And yeah, it seems the description is a bit out of date as I ended up moving some parts into other PRs, but I'll make sure to fix it before merging
