Contributing Guide

Welcome! We are glad that you want to contribute to our project! 💖

As you get started, you are in the best position to give us feedback on areas of our project that we need help with, including:

  • Problems found during setting up a new developer environment
  • Gaps in our Quickstart Guide or documentation
  • Bugs in our automation scripts

If anything doesn't make sense, or doesn't work when you run it, please open a bug report and let us know!

Ways to Contribute

We welcome many different types of contributions, including:

  • New features
  • Builds, CI/CD
  • Bug fixes
  • Documentation
  • Issue Triage
  • Answering questions on Slack/Mailing List
  • Web design
  • Communications / Social Media / Blog Posts

Find an Issue

We have good first issues for new contributors and help wanted issues suitable for any contributor. good first issue has extra information to help you make your first contribution. help wanted are issues suitable for someone who isn't a core maintainer and is good to move onto after your first pull request.

Sometimes there won’t be any issues with these labels. That’s ok! There is likely still something for you to work on.

Once you see an issue that you'd like to work on, please post a comment saying that you want to work on it. Something like "I want to work on this" is fine.

Ask for Help

The best way to reach us with a question when contributing is to ask on:

  • The original github issue
  • The developer mailing list
  • Our Slack channel

Local Development

This section describes how to setup your local development environment and test your code changes.

First, follow the Quickstart Guide in odigos docs to create a local k8s development cluster with a demo application and a functioning odigos installation.

Make sure you are able to:

  • run Odigos cli in your terminal.
  • open the demo application ui in your browser to interact with it.
  • install odigos in your development cluster with odigos install.
  • open odigos ui in your browser to interact with it.
  • see telemetry data that odigos generates, for example traces in jaeger.

After you have a working odigos setup, you can start making changes to the code and test them locally.

Run Odigos Cli from code

The code for the odigos cli tool is found in the cli directory here. Test your cli code changes by running go run . from the cli directory:

➜  odigos git:(main) cd cli/
➜  cli git:(main) go run .
  • To run odigos install cli command from a local source, you will need to supply a version flag to tell odigos which image tags to install:
➜  cli git:(main) go run . install --version v0.1.81
Installing Odigos version v0.1.81 in namespace odigos-system ...
  • If you test changes to the install command, you will need to go run . uninstall first before you can go run . install again.

How to Develop Odigos Locally

The main steps involved when debugging Odigos locally are:

  • Use a Kind kubernetes cluster
  • Build custom images of Odigos and load them into Kind via:
TAG=<CURRENT-ODIGOS-VERSION> make build-images load-to-kind
  • Ensure the TAG matches the Odigos version output from: odigos version
  • Restart all pods in the odigos-system namespace:
kubectl delete pods --all -n odigos-system

See the Odigos docs for the full steps on debugging Odigos locally.

How to Build and run Odigos Frontend Locally

  • go to frontend/webapp
  • run:
 npm run build
  • go to frontend folder
  • run:
go build -o odigos-backend && ./odigos-backend --port 8085 --debug --address 0.0.0.0
  • go to frontend/webapp
  • run:
 npm run dev

Odiglet

builder base image

Odiglet Dockerfile uses a base image for the builder, which saves up lots of time during builds. The Dockerfile for the base image can be found in ./odiglet/base.Dockerfile and is consumed like so: FROM keyval/odiglet-base:v1.0 as builder If you need to add additional packages to the build, update this file. Then publish the new base image to dockerhub with the github action named Publish Odiglet Base Builder in the Actions tab. You will need to specify the new image tag as a version in the format v1.0. After the image is published, update the dependency in ./odiglet/Dockerfile to use the new image tag.
