Developing

Environment Setup

Essentials:

1. Install Go

Optionals:

1. Tilt v0.13+ (to deploy on a local dev K8s cluster)
2. kind v0.8+ (to spin up a local dev K8s cluster)
3. kustomize v3.6+

Running

This project uses tilt to deploy to local Kubernetes cluster. In order to do this you need a local Kuberetes cluster (kind is recommended).

kind create cluster --name matterbuild

Matterbuild deployment to any cluster and any environment (dev, prod, etc) depends on existense of deploy/config/config.json file, this file is .gitignored and you can safeley choose to copy sample config there for local development and testing:

cp config.json deploy/config/

Point KUBECONFIG to the newly created cluster, and start tilt and open http://localhost:8080/:

make run

Note: If you don't want to use Tilt nor deploy to local cluster you can ignore it and simply start the binary server:

NOTILT=1 make run

Testing

Running all tests:

make test

Generate github mocks:

make mocks
