I am new to istio and am trying to send istio logs to cloudwatch. I have read over the adapter model https://istio.io/blog/2017/adapter-model/ and somewhat have an idea of what a handler, template, instance, and rule is. However I am stumped on how to proceed. I imagine I need to write my own handler, template, instance, and rules for the cloudwatch adapter? Where would these files actually live / how would they be applied? What would they look like? I can’t really find any documentation on this, and have been reading up all day.
