Not sure how Varun has been testing the identity so far but this should work:
```
cd services/identity
docker-compose up --build identity-server
```
For now it kind of hangs, but I added explicitly:
```
println!("Hello");
return Ok(());
```
in the beginning of the `main` function in the `main.rs` file and it prints `Hello`. That means it successfully copies the proto file, then builds from this proto file and then compiles the sources, so I consider it working.
