Crossplane sample that talks through Grpc Server

That project is an example for crossplane provider. Provider talks to grpc server to do CRUD operation

prepare local k8s cluster

kind

kind create cluster --name k8s-crossplane
kind get clusters
kubectl cluster-info --context kind-k8s-crossplane
## export kubeconfig
export KUBECONFIG="$(kind get kubeconfig --name='k8s-crossplane')"

crossplane install

helm repo add crossplane-stable https://charts.crossplane.io/stable
helm repo update
helm install crossplane \
--namespace crossplane-system \
--create-namespace crossplane-stable/crossplane

!!! if you run controller as an image instead of make run, use host.docker.internal to reach grpc-server running locally from local k8s cluster https://docs.docker.com/desktop/networking/#i-want-to-connect-from-a-container-to-a-service-on-the-host

clone provider userprovider and prepare provider

# fetch the [upbound/build] submodule by running the following
make submodules

# update template with your provider name
export provider_name=UserProvider
make provider.prepare provider=${provider_name}

# add User kind under playground group
export group=playground
export type=User
make provider.addtype provider=${provider_name} group=${group} kind=${type}

# register new APIs and Controllers
## 1. apis/userprovider.go
## 2. internal/controller/userprovider.go

# generate the code
make generate

# run grpc server
go run ./grpc-server/main.go

# run controller
make run

# apply configs under package/crds
kubectl apply -f package/crds

# update example yaml
kubectl apply -f ./examples/sample/example.yaml
