Mac Requirement (M1/M2)

# clean up colima install BEWARE!! older version of colima sometimes are failing
rm -rf ~/.colima ~/.lima

# start colima with kubernetes option and disable Traefik
colima start --kubernetes --kubernetes-disable=traefik  --arch aarch64 --vm-type=vz --vz-rosetta --cpu 2 --memory 4

Installation

# install using yaml
kubectl apply -f https://github.com/envoyproxy/gateway/releases/download/v0.6.0-rc.1/install.yaml -n envoy-gateway-system

# or install using helm
helm install eg oci://docker.io/envoyproxy/gateway-helm --version v0.6.0-rc.1 -n envoy-gateway-system --create-namespace
