## ✅ Step-by-step: Connect Rust to containerd via gRPC
CREATE A rhai script executing the following instructions below
use all rhai script features we have + give priority to what functions we have defined in /src/docs/docs/sal in this repo
---
### 1. 🧱 Install Dependencies
Add this to your `Cargo.toml`:
```toml
[dependencies]
tonic = "0.11"
prost = "0.12"
tokio = { version = "1", features = ["full"] }
[build-dependencies]
tonic-build = "0.11"
```
---
### 2. 📁 Clone containerd's gRPC proto files
```bash
git clone https://github.com/containerd/containerd.git
cd containerd
```
Containerd's API protos are in:
```
api/services/ # gRPC service definitions
api/types/ # message types
```
---
### 3. 📦 Set up `build.rs` to compile protos
In your Rust project root, create a `build.rs` file:
```rust
fn main() {
tonic_build::configure()
.build_server(false)
.compile(
&[
"containerd/api/services/images/v1/images.proto",
"containerd/api/services/containers/v1/containers.proto",
// Add more proto files as needed
],
&[
"containerd/api",
"containerd/api/types"
],
)
.unwrap();
}
```
Make sure to place the `containerd` directory somewhere your build can see — for example, symlink it or move it into your project as `proto/containerd`.
---
### 4. 🧪 Example: Connect to containerd's image service
After `build.rs` compiles the protos, your code can access them like this:
```rust
use tonic::transport::Channel;
use containerd::services::images::v1::{
images_client::ImagesClient,
GetImageRequest,
};
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Connect to containerd's gRPC socket (default path)
let channel = Channel::from_static("http://[::]:50051") // placeholder
.connect()
.await?;
let mut client = ImagesClient::new(channel);
let response = client.get(GetImageRequest {
name: "docker.io/library/ubuntu:latest".to_string(),
}).await?;
println!("Image: {:?}", response.into_inner());
Ok(())
}
```
🔧 Note: containerd uses a **Unix socket**, so replace the channel connection with:
```rust
use tonic::transport::{Endpoint, Uri};
use tower::service_fn;
use hyper_unix_connector::UnixConnector;
let uds = tokio::net::UnixStream::connect("/run/containerd/containerd.sock").await?;
let channel = Endpoint::try_from("http://[::]:50051")?
.connect_with_connector(service_fn(move |_| async move {
Ok::<_, std::io::Error>(uds)
}))
.await?;
```
(We can wrap that part into a helper if you want.)
---
### 5. 🔁 Rebuild the project
Each time you add or change a `.proto`, rebuild to regenerate code:
```bash
cargo clean && cargo build
```
