+# Package Orchestration apiserver
+
+Created from https://github.com/kubernetes/sample-apiserver
+
+
+## Getting Started
+
+Clone this repository into `${GOPATH}/src/github.com/GoogleContainerTools/kpt`.
+
+```sh
+git clone https://github.com/GoogleContainerTools/kpt.git "${GOPATH}/src/github.com/GoogleContainerTools/kpt"
+cd "${GOPATH}/src/github.com/GoogleContainerTools/kpt"
+```
+
+Download dependencies:
+
+```sh
+make tidy
+```
+
+Run; Porch is implemented as an extension k8s apiserver so to run it, we need:
+* main apiserver
+* etcd (to back the main apiserver)
+* Porch (the extension apiserver)
+
+But first we need to create docker network for all the containers to run on:
+
+```sh
+make network
+```
+
+```sh
+# Start etcd
+make start-etcd
+
+# Start main apiserver
+make start-kube-apiserver
+
+# Start porch
+make run-local
+
+```
+
+To teardown the Docker containers and network:
+
+```sh
+make stop
+```
+
+### Registering a Repository
+
+Update the example configs of [git-repository.yaml](./config/samples/git-repository.yaml)
+or [oci-repository.yaml](./config/samples/oci-repository.yaml)
+with your Git repository or OCI repository respectively.
+
+For Git:
+
+* Create a Git repository for your blueprints.
+* GitHub: Create a [Personal Access Token](https://github.com/settings/tokens) to use with Porch
+* Create a secret with the token:
+  ```sh
+  kubectl create secret generic git-repository-auth \
+    --namespace=default \
+    --from-literal=username=<GitHub username> \
+    --from-literal=token=<GitHub Personal Access Token>
+  ```
+* Update the [git-repository.yaml](./config/samples/git-repository.yaml) with your repository address
+* Register the repository:
+  ```sh
+  KUBECONFIG=./hack/local/kubeconfig kubectl apply -f ./config/samples/git-repository.yaml
+  ```
+
+For OCI:
+
+* Create an [Artifact Registry repository](https://console.cloud.google.com/artifacts)
+* Update the [oci-repository.yaml](./config/samples/oci-repository.yaml) with your OCI repository address
+* Make sure your application default credentials are up-to-date, i.e. by running:
+  ```sh
+  gcloud artifacts docker images list <your OCI repository address>
+  ```
+* Register the repository:
+  ```sh
+  KUBECONFIG=./hack/local/kubeconfig kubectl apply -f ./config/samples/oci-repository.yaml
+  ```
+
+List the package revisions:
+
+```sh
+export KUBECONFIG="$(pwd)/hack/local/kubeconfig"
+kubectl get packagerevisions -oyaml
+kubectl get packagerevisionresources -oyaml
+```
+
+Or create a pakcage revision:
+```sh
+kubectl apply -f ./config/samples/bucket-label.yaml
+```
+
+## Development
+
+### Changing Types
+
+If you change the API object type definitions in any of the
+`api/porch/.../types.go`, update the generated code by running:
+
+```sh
+make generate
+```
+
+## Run in GKE Cluster
+
+Prerequisite:
+* Create GKE cluster
+* Create appropriate KUBECONFIG.
+
+### Build the Container Image
+
+Build a Docker image using a script:
+
+```sh
+./hack/build-image.sh
+
+# Supported flags
+# --repository [REPO]      name of the Docker repository
+# --project    [PROJECT]   GCP project (will translate to gcr.io/PROJECT)
+# --tag [TAG]              image tag, i.e. 'latest'
+# --push                   also push the image to the repository
+
+
+# Example
+./hack/build-image.sh --project=my-gcp-project --push
+```
+
+Or, build directly via docker:
+**Note**: This must be done from the parent directory (kpt, not porch):
+
+```sh
+docker build -t TAG -f ./porch/hack/Dockerfile .
+```
+
+### Deploy into a Kubernetes Cluster
+
+Edit `config/deploy/2-deployment.yaml`, updating the pod template's image
+reference to match what you pushed and setting the `imagePullPolicy`
+to something suitable.  Then call:
+
+```sh
+# Create CRDs
+kubectl apply -f ./controllers/pkg/apis/porch/v1alpha1/
+# Deploy Porch apiserver extension.
+kubectl apply -f ./config/deploy/
+```
+
+When running you can:
+
+```sh
+# notice porch.kpt.dev/v1alpha1 in the result
+kubectl api-resources
+
+# List packagerevisions
+kubectl get packagerevisions --namespace default
+```
+
+Follow the instructions above on how to register repositories and discover packges.
+
+### Running Locally
+
+Porch is an extension k8s apiserver. As such, it needs the main apiserver, which in turn needs `etcd`.
+
+Start `etcd` and main apiserver:
+
+```sh
+make start-etcd
+make start-kube-apiserver
+```
+
+Now, start the porch apiserver:
+
+```sh
+make run-local
+
+# Call the server
+KUBECONFIG=./hack/local/kubeconfig kubectl api-resources
+# List package revisions
+KUBECONFIG=./hack/local/kubeconfig kubectl get packagerevisions --namespace default
+```
