title: Deploy 2 k8s using kops
type: text/vnd.tiddlywiki

```sh
# Configure AWS CLI -
aws configure

# Export Kops variables so Kops knows of the AWS cluster
export KOPS_CLUSTER_NAME=difa-test.k8s.local
export KOPS_STATE_STORE=s3://digitalefactuur-tst-kops-state-store

# Export kubeconfig
kops export kubecfg

# Run Kubernetes Dashboard on localhost as a background service
kubectl proxy &

# Check the status of the Kubernetes cluster
kops validate cluster

# Edit the AWS nodes in a YAML file (instance type, min, max nodes)
kops edit ig nodes

# Update AWS cluster using Kops - specify --yes to make actual changes
kops update cluster

# Check metrics of AWS nodes
kubectl top nodes

# top of nodes
kubectl top nodes

# change nodes
kops edit instancegroup nodes
kops update cluster --yes

# Rolling update AWS cluster - specify --yes to make actual changes
kops rolling-update cluster --yes

# password for dashboard
kops get secrets admin --type secret -oplaintext
```

```sh
helm del --purge database ; sleep 5; helm install --name database $GENIFER_HOME/operations/helm/databases

helm del --purge genifer-release ; sleep 5; helm install --name genifer-release $GENIFER_HOME/operations/helm/genifer

Heb de loadbalancer service om moeten bouwen naar een ingress nginx service, daarna een cert-manager tutorial gevolgd om https te kunnen gebruiken via letsencrypt.

Gebruiken nu:

* nginx ingress controller  (Layer 4) tutorial: https://kubernetes.github.io/ingress-nginx/deploy/#aws
* external dns, hierdoor zal de dns automatisch toegewezen worden aan je subdomein die je in je ingress definieert (via route53): https://github.com/kubernetes-incubator/external-dns/blob/master/docs/tutorials/aws.md
* cert manager tutorial: https://docs.cert-manager.io/en/latest/getting-started/install/kubernetes.html
* cert aanmaak tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nginx-ingress-with-cert-manager-on-digitalocean-kubernetes (edited)
