My own Dapr

A simple example showing how you can create your own custom Dapr sidecar binary (daprd).

How it works

Go leverages Git repositories as dependencies. This means that it is possible to use Dapr as a library in other Go programs. To make our own customer Dapr sidecar, all we need to do is create a small program with just the components we want included and starts the runtime. Easy, right!

Changine the Dapr runtime version or included components

This project already has a customized daprd program that only includes Redis as an example. To customize which components are included in the binary, simply copy this main.go into cmd/daprd and add/remove component registrations. You can even provide your own components.

Next, overwrite the entire contents go.mod with this snippet (retrofit the module name and desired Dapr version).

module github.com/pkedy/my_own_dapr

go 1.17

require (
	github.com/dapr/components-contrib v1.6.0
	github.com/dapr/dapr v1.6.0
)

Then from the terminal, run go mod tidy --compat=1.17 and the rest of the required dependencies will be included.

Finally, make sure that DAPR_RELEASE in the Makefile is set to the Dapr version you want (e.g., 1.6.0). This is so that the docker image tag includes the correct version.

Building

You'll want to tweak the Makefile to change the docker image tag to your liking. Then run make docker.
