# kind-cluster

Create and Test on a Kubernetes cluster with kind

# Quick start

To create a cluster you can either run the following script making sure you have kubectl and go installed on your machine, code of installation is available in the **Dockerfile**, then you can run the following:

```sh

docker compose up --build -d

# Export kubeconfig to host (make sure to update server host to localhost)

# If server host different from localhost you will need to ignore ca and add (insecure-skip-tls-verify: true)

docker cp cluster-generator:/root/.kube/config ./config

# Export env vars (windows)

$env:KUBECONFIG="$PWD/config/config"

# Export env vars (linux)

KUBECONFIG="$(pwd)/config/config"

# Check cluster nodes

kubectl get nodes -o wide

# Get cluster name 

docker exec -it cluster-generator bash -c "kind get clusters"

# In case cluster restarted (TODO: Fix check and reconfigure)

docker exec -it cluster-generator bash -c "docker cp k8s-cluster-control-plane:/etc/kubernetes/admin.conf /root/.kube/config && sed -i 's#server:.*#server: https://localhost:6442#g' /root/.kube/config"

```

# Deploy and access

Since apiserver address is **0.0.0.0** you can access the exposed ports from anywhere

```sh

# Load image inside cluster

kubectl create deployment nginx --image nginx:alpine

kubectl port-forward --namespace default deploy/nginx 9922:80 --address 0.0.0.0 # Visit localhost:9922

```

# Manage images

```sh

# Load image inside cluster (kind load docker-image --name k8s-cluster alpine)

docker exec -it cluster-generator bash -c "docker pull nginx && kind load docker-image --name k8s-cluster nginx" 

```

# Helm

```sh

# Example helm grafana cluster chart

helm repo add groundcover https://helm.groundcover.com/

helm repo update

helm install caretta --namespace caretta --create-namespace groundcover/caretta

kubectl get all -n caretta

kubectl port-forward --namespace caretta deploy/caretta-grafana 3000:3000 --address 0.0.0.0

```

# Plugins

In this example I have installed some kubectl plugins as well as some helm plugins:

```sh

# Visit: https://krew.sigs.k8s.io/plugins/

# kubectl get pod PODNAME -o yaml | kubectl neat

# kubectl access-matrix for deployment

# kubectl node-shell k8s-cluster-worker

kubectl krew info cost

kubectl plugin list

kubectl krew install 

```
