## Getting Started
You’ll need a Kubernetes cluster to run against. You can use [KIND](https://sigs.k8s.io/kind) to get a local cluster for testing, or run against a remote cluster.
**Note:** Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster `kubectl cluster-info` shows).

### Additional setup on Machintosh computers
On Macintosh computers some additional setup is necessary to install and configure compatible tooling.

#### Install Homebrew and tools
Follow the instructions to [installing Homebrew](https://docs.brew.sh/Installation) and then execute the following to install tools:

```sh
brew install bash gnu-tar gsed
```

#### Configure your shell
Modify your login shell's `PATH` to prefer the new tools over those in the existing environment. This example should work either with `zsh` (in $HOME/.zshrc) or `bash` (in $HOME/.bashrc):

```sh
for bindir in `find $(brew --prefix)/opt -type d -follow -name gnubin -print`

I normally try to avoid running commands in .zshrc because it can slow down creation of a new session significantly. Maybe it is not that big of a deal with brew --prefix and find, but I had this issue with npm.

If we can avoid this - that would be great. Here is my .zshrc:

# coreutils
PATH="/opt/homebrew/opt/coreutils/libexec/gnubin:$PATH"

# gnu-tar
PATH="/opt/homebrew/opt/gnu-tar/libexec/gnubin:$PATH"

Not sure if coreutils are necessary for OLMv1.

But we might still need to use brew --prefix. I think it it is different on Intel and ARM Macs unfortunately.

I've been doing this for quite awhile never encountered new session timing issues, though I appreciate the concern. The additional advantage of the approach is that if we identify we need additional tooling, sourcing the resource file will automagically pick it up.

npm is known for sometimes performing package maintenance at awkward times, and I definitely wouldn't want to include a function in shell resources which invoked it. I see no harm in a targeted path-walk though.

As far as I know we only need bash, gnu-tar, and gsed, unless you can think of a reason that we need coreutils...

Ok, it is not that bad. At least on my machine :)

do
export PATH=$bindir:$PATH
done
```
