A minimalist Application Container in Rust for learning purposes
Simple Container System in Rust 📦🦀
A minimalistic container system built with Rust. This project provides a basic implementation of container features, demonstrating how applications can be isolated and run in a separate environment. Perfect for those seeking to understand the foundational principles behind container technology.
You can read the step-by-step guide on this Article: Impĺementing an Application Container in Rust
Features 🌟
- Isolated Environment: Uses Linux namespaces to achieve process and filesystem isolation.
- Simple CLI: Deploy and run applications with ease.
- Statically Linked Application Support: Designed to run applications without external dependencies for maximum simplicity.
Getting Started 🚀
Prerequisites
- Rust (latest stable version)
- Cargo
Installing the 'libc' package on Linux OS
Before getting started with the crate, you'll want to make sure you've got the libc package set up on your system.
For Debian-based systems like Ubuntu, the C library is provided by the libc6 package, and the header files are in the libc6-dev package. You can install it with:
sudo apt update
sudo apt install libc6-dev
Installation
Clone the repository:
git clone https://github.com/luishsr/rust_container.git
cd simple-container-rust
Build the project:
cargo build --release
For Running the Project, I recommend starting with the containerclient example we built in the Article, as it does not require libraries' dependencies (as it is statically linked). But you can try it with any application, as long as you copy the libs dependencies of your application along with its binaries.
Using the sample containerclient for testing the Container deployment:
CD into the containerclient project:
cd containerclient
Install the MUSL Target:
rustup target add x86_64-unknown-linux-musl
Build the project manually using the :
cargo build --release --target x86_64-unknown-linux-musl
This will produce a statically linked binary in the target/x86_64-unknown-linux-musl/release/ directory.
Deploying and Running ContainerClient in Our Simple Container
Deploying the ContainerClient Application:
sudo ./rustcontainer deploy ./containerclient
Running the ContainerClient Application Inside the Container:
sudo ./rustcontainer run ./containerclient
If all went well, you should see:
Hello from the container!
And that's it! With these simple steps, you've deployed and executed your containerclient application inside our minimalist container environment. Enjoy experimenting with it!
