Development Environment in Local

This is a list of development environment in local for macOS:

  • docker-desktop >= 4.13.1
  • kubernetes >= 1.25.2
  • istioctl >= 1.15.3
  • protobuf >= 21.8
  • go >= 1.19
  • mysql >= 8.0

Install the Docker Desktop,and enable Kubernetes cluster, See the docker docs

# install Go
brew install go
# install MySQL without a root password
brew install mysql
# install Protobuf
brew install protobuf
# install Buf
brew install bufbuild/buf/buf
# install istioctl
brew install istioctl
# ensure you change the context so that kubectl is pointing to docker-desktop
kubectl config use-context docker-desktop
# install and enable istio
istioctl install -y
kubectl label namespace default istio-injection=enabled

Deploy the demo in Kubernetes

# build docker images
make docker-build
# deploy all services
make kube-deploy
