eunomia-template

Welcome to the eunomia-template! This project template is designed to help you quickly start developing eBPF projects using eunomia-bpf in C. The template provides a solid starting point with a Makefile, Dockerfile, and GitHub action, along with all necessary dependencies to simplify your development process.

借助于 GitHub 模板和 Github Codespace，可以轻松构建 eBPF 项目和开发环境，一键在线编译运行 eBPF 程序。关于中文的文档和详细的 eBPF 开发教程，可以参考：https://github.com/eunomia-bpf/bpf-developer-tutorial

There are other templates for other languages:

• https://github.com/eunomia-bpf/libbpf-template: eBPF project template based on the C language and the libbpf framework.
• https://github.com/eunomia-bpf/cilium-ebpf-starter-template: eBPF project template based on the Go language and the cilium/ebpf framework.
• https://github.com/eunomia-bpf/libbpf-rs-starter-template: eBPF project template based on the Rust language and the libbpf-rs framework.

Getting Started

To get started, simply click the "Use this template" button on the GitHub repository page. This will create a new repository in your account with the same files and structure as this template.

Use docker

Run the following code to run the eBPF code from the cloud to your local machine in one line:

$ sudo docker run --rm -it --privileged ghcr.io/eunomia-bpf/eunomia-template:latest
TIME     EVENT COMM             PID     PPID    FILENAME/EXIT CODE
09:25:14 EXEC  sh               28142   1788    /bin/sh
09:25:14 EXEC  playerctl        28142   1788    /nix/store/vf3rsb7j3p7zzyjpb0a3axl8yq4z1sq5-playerctl-2.4.1/bin/playerctl
09:25:14 EXIT  playerctl        28142   1788    [1] (6ms)
09:25:15 EXEC  sh               28145   1788    /bin/sh
09:25:15 EXEC  playerctl        28145   1788    /nix/store/vf3rsb7j3p7zzyjpb0a3axl8yq4z1sq5-playerctl-2.4.1/bin/playerctl
09:25:15 EXIT  playerctl        28145   1788    [1] (6ms)

Use Nix

Using direnv and nix, you can quickly access a dev shell with a complete development environment.

With direnv, you can automatically load the required dependencies when you enter the directory. This way you don't have to worry about installing dependencies to break your other project development environment.

See how to install direnv and Nix:

• direnv: https://github.com/direnv/direnv/blob/master/docs/installation.md
• Nix: run

sh <(curl -L https://nixos.org/nix/install) --daemon

Then use the following command to enable direnv support in this directory.

direnv allow

If you want use nix flake without direnv, simply run:

nix develop

Features

This starter template includes the following features:

• A Makefile that allows you to build the project in one command
• A Dockerfile to create a containerized environment for your project
• A flake.nix to enter a dev shell with needed dependencies
• A GitHub action to automate your build and publish process and docker image
• All necessary dependencies for C development with eunomia-bpf

How to use

1. Create a new repository using this template

Click the "Use this template" button on the GitHub repository page to create a new repository based on this template.

2. Clone your new repository

Clone your newly created repository to your local machine:

git clone https://github.com/your_username/your_new_repository.git

3. Install dependencies

For dependencies, it varies from distribution to distribution. You can refer to shell.nix and dockerfile for installation.

On Ubuntu, you may run make install or

sudo apt-get install -y --no-install-recommends \
        libelf1 libelf-dev zlib1g-dev \
        make clang llvm

to install dependencies.

4. Build the project

To build the project, run the following command:

make build

This will compile your code and create the necessary binaries. You can you the Github Code space or Github Action to build the project as well.

Run the Project

You can run the binary with:

ecli run src/package.json

Or with Github Packages locally:

docker run --rm -it --privileged -v $(pwd):/examples ghcr.io/eunomia-bpf/eunomia-template:latest

7. GitHub Actions

This template also includes a GitHub action that will automatically build and publish your project when you push to the repository. To customize this action, edit the .github/workflows/publish.yml file.
