Setup

Create a cluster using Kind

kind create cluster --name=homelab-dev

You should be able to see the newly created cluster along with the Docker Desktop cluster (if you are running it)

$ kubectl config get-clusters

NAME
kind-homelab-dev
docker-desktop

When you're done, simply delete it using the name homelab-dev. Even though listing the clusters, gives the name as kind-homelab-dev, the kind- prefix is not needed.

$ kind delete cluster --name=homelab-dev

Setting up SSL

Once you've set up the Cloudflare credentials, you'll need to run

docker run -it --rm -v $(pwd)/etc:/etc/letsencrypt -v $(pwd):/certs certbot/dns-cloudflare certonly --dns-cloudflare --dns-cloudflare-credentials /certs/cloudflare.ini -d "internal.mrida.ng,*.internal.mrida.ng" --preferred-challenges dns-01

This will prompt you for a confirmation and your email address then save the issued certs under the etc directory.

kubectl delete configmap kibana-kibana-helm-scripts -n default kubectl delete serviceaccount pre-install-kibana-kibana -n default kubectl delete roles pre-install-kibana-kibana -n default kubectl delete rolebindings pre-install-kibana-kibana -n default kubectl delete job pre-install-kibana-kibana -n default

ECK (Operator)

Each pod runs a sidecar to collect application-specific logs if needed but along with that a generic DaemonSet is run to collect application logs.

Nginx (Chart)

Nginx is used to serve a simple hello-world page. This acts as a lightweight container that can be used for testing

Traefik (Chart)

Traefik is used as the ingress controller for the cluster.

Dashboard (Chart)

The default K8 dashboard is deployed so that we can inspect the cluster.

Steampipe

Steampipe has been configured on the CLI. This makes it easy to query the cluster via SQL.

You can either start the interactive shell using devbox run steampipe or run a query directly like the example below.

$ steampipe query "SELECT name FROM kubernetes_pod"

+-------------------------------------------------+
| name                                            |

| elastic-operator-0

| my-kibana-kb-786f98bfc9-v7x7w                   |
| ts-tailscale-apm-ingress-v9qzc-0                |
| filebeat-beat-filebeat-g66jc                    |
| traefik-6f99669b8d-cxxbt                        |
| ts-tailscale-dashboard-ingress-wz786-0          |
