Running slurm-bridge locally

Overview

You may want to run slurm-bridge on a single machine in order to test the software or familiarize yourself with it prior to installing it on your cluster. This should only be done for testing and evaluation purposes and should not be used for production environments.

We have provided a script to do this using Kind and the hack/kind.sh script.

This document assumes a basic understanding of Kubernetes architecture. It is highly recommended that those who are unfamiliar with the core concepts of Kubernetes review the documentation on Kubernetes, pods, and nodes before getting started.

Pre-requisites

go 1.17+ must be installed on your system

Setting up your environment

Install Kind using go install:
```
go install sigs.k8s.io/kind@v0.29.0
```
If you get kind: command not found when running the next step, you may need to add GOPATH to your PATH:
```
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
```

Confirm that kind is working properly by running the following commands:

kind create cluster

kubectl get nodes --all-namespaces

kind delete cluster

Clone the slurm-bridge repo and enter it:

git clone git@github.com:SlinkyProject/slurm-bridge.git
cd slurm-bridge

Installing `slurm-bridge` within your environment

Provided with slurm-bridge is the script hack/kind.sh that interfaces with kind to deploy the slurm-bridge helm chart within your local environment.

Create your cluster using hack/kind.sh:
```
hack/kind.sh --bridge
```

Familiarize yourself with and use your test environment:

kubectl get pods --namespace=slurm-bridge
kubectl get pods --namespace=slurm
kubectl get pods --namespace=slinky

At this point, you should have a kind cluster running slurm-bridge.

Cleaning up

hack/kind.sh provides a mechanism by which to destroy your test environment.

Run:

hack/kind.sh --delete

To destroy your kind cluster.
