To build Karpenter from source, please first install the following:

1. [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
2. [kustomize](https://kubernetes-sigs.github.io/kustomize/installation/)
3. [controller-gen](https://book.kubebuilder.io/reference/controller-gen.html); to install it you can do:

CONTROLLER_GEN_TMP_DIR=$(mktemp -d)
cd $CONTROLLER_GEN_TMP_DIR
go mod init tmp
go get sigs.k8s.io/controller-tools/cmd/controller-gen@v0.2.5
rm -rf $CONTROLLER_GEN_TMP_DIR

After installing the dependencies from the previous section, as well as those in the [README](README.md), you should be able to build the software:

```bash
make
```

Thinking about this -- do you need to put this line in our Makefile as well? AWSK8sTester has abstracted out the build logic to be shared between make and docker. We should consider this if it gets too complex.

Yeah, I guess we could - at some point it gets a bit too complicated (and plus it's kind of specific to us, or other folks who might be working on this from inside a network where there are going to be proxies in front of stuff). Right now I'm just setting this in my .bashrc.

2. [docker](https://docs.docker.com/install/)

## Install
TODO

Make sure you have set `KO_DOCKER_REPO` before running the following commands:

```bash
make docker-release
```

If the above works, then you can deploy to your Kubernetes cluster:

```bash
make deploy
```

# AWS Developer Guide

This file walks through any steps needed when developing Karpenter using AWS services.

## Set up EKS Cluster

_TODO_

## Set up ECR

If you plan on using the AWS ECR and haven't yet set it up, you will want to do something like the following (which come from [these instructions](https://docs.aws.amazon.com/AmazonECR/latest/userguide/getting-started-cli.html)

```bash
# Replace the values in the following 2 lines:
AWS_ACCOUNT_ID=my-account-id
AWS_REGION=region
aws ecr get-login-password --region $AWS_ACCOUNT_ID | docker login --username AWS --password-stdin ${AWS_ACCOUNT_ID}.dkr.ecr.${AWS_REGION}.amazonaws.com
aws ecr create-repository --repository-name karpenter --image-scanning-configuration scanOnPush=true --region ${AWS_REGION}
```

You will then want to add the following to your shell's init script:

```bash
export KO_DOCKER_REPO=${AWS_ACCOUNT_ID}.dkr.ecr.${AWS_REGION}.amazonaws.com
```
