How to use devs with dapr?

[huang12zheng]

dapr is to build distributed applications. With Service Invocation, publish subscribe, secret management, binding, statemanagement,virtual actors.

In my option,
With devs , It looks like, a packed mirror is being uploaded to the k8s.
But it is need a s.yaml

s.yaml doesn't look like components/.yaml, which defined image trait to k8s with kubectl -f.
And components/.yaml is sidecar to business.

Thoughts as I write here,
My business code also needs to bind to sidecar instead of simply uploading the business image.
If I'm wrong, you can point it out.
