bug: DNS not resolving service name to IP address

[hydai]

Related issue:

1. DNS not resolving service name to IP address in a Rust compiled to WASM container moby/moby#47403
2. Fix DNS error on WASM adding static IPs to every container on a new network #22

The current status:

1. WASM container cannot resolve the service name
2. The DNS server of docker-compose is still 127.0.0.11:53
3. The DNS_SERVER magic is not working.
4. The wasi-socket component inside WasmEdge is not changed.
5. We should check all used wasi-socket crates to see if there are some modifications related to this problem <-- We are here now

My understanding of Rust is super basic, but I was planning on learning it... Something in which I can help?

The related code is under these three crates: https://github.com/second-state/microservice-rust-mysql/blob/main/Cargo.toml#L11-L13

If you would like to dig into the details, please check the error caused in the microservice-rust-mysql and find which crates are highly related to the error.

Can you assign this to me? i will try my best to solve it. If I can't, I'll let you know.

[hydai]

Sure. Here you go.

I'm nearly 99% sure that the problem is with tokio_wasi crate, making some tests rn

As you can see in WasmEdge/tokio@f6dae1c this problem seems to be solved, but anyway it still failing. Apparently, it has like version conflicts because the repo references 1.28.2 as the latest version but it's not published on crates.io

#24 has the solution
