Running Porch Locally

Prerequisites

To run Porch locally, you will need:

Linux machine (technically it is possible to run Porch locally on a Mac but due to differences in Docker between Linux and Mac, the Porch scripts are confirmed to work on Linux)
go 1.21 or newer
docker
git
kubectl
make

Getting Started

Clone this repository into ${GOPATH}/src/github.com/GoogleContainerTools/kpt.

git clone https://github.com/GoogleContainerTools/kpt.git "${GOPATH}/src/github.com/GoogleContainerTools/kpt"

Download dependencies:

make tidy

Running Porch

Porch consists of:

k8s extension apiserver porch
kpt function evaluator func
k8s controllers

In addition, to run Porch locally, we need to run the main k8s apiserver and its backing storage, etcd.

To build and run Porch locally in one command, run:

# Go into the porch directory:
cd "${GOPATH}/src/github.com/GoogleContainerTools/kpt/porch"

# Start Porch in one command:
make

This will:

create Docker network named porch
build and start etcd Docker container
build and start main k8s apiserver Docker container
build and start the kpt function evaluator microservice func Docker container
build Porch binary and run it locally
configure Porch as the extension apiserver

Note

This command does not build and start the Porch k8s controllers. Those are not required for basic package orchestration but are required for deploying packages.

You can also run the commands individually which can be useful when developing, in particular building and running Porch extension apiserver.

# Create Porch network
make network

# Build and start etcd container
make start-etcd

# Build and start main apiserver container
make start-kube-apiserver

# Build and start kpt function evaluator microservice Docker container
make start-function-runner

# Build and start Porch on your local machine.
make run-local

Porch will run directly on your local machine and API requests will be forwarded to it from the main apiserver. Configure kubectl context to interact with the main k8s apiserver running as Docker container:

export KUBECONFIG=${PWD}/deployments/local/kubeconfig

# Confirm Porch is running
kubectl api-resources | grep porch

repositories                  config.porch.kpt.dev/v1alpha1          true         Repository
functions                     porch.kpt.dev/v1alpha1                 true         Function
packagerevisionresources      porch.kpt.dev/v1alpha1                 true         PackageRevisionResources
packagerevisions              porch.kpt.dev/v1alpha1                 true         PackageRevision

Restarting Porch

If you make code changes, an expedient way to rebuild and restart porch is:

Stop Porch running in the shell session (Ctrl+C)
Run make run-local again to rebuild and restart Porch

Stopping Porch

To stop Porch and all associated Docker containers, including the Docker network, run:

make stop

Troubleshooting

If you run into issues that look like git: authentication required, make sure you have SSH keys set up on your local machine.
