Using k3d with Codezero

In order to use a local kubenetes cluster such as k3d with codezero you need an external local balancer so that other members of your team route traffic to and from your cluster.

To do that we make use of the inlets-controller from inlets.dev

Install a local kubenetes cluster

Using k3d v5.6.0 from https://k3d.io/v5.6.0/

brew install k3d

Create a cluster without a load-balancer

k3d cluster create czdemo --api-port 6550 --agents 1 \
  --k3s-arg "--disable=traefik@server:0" \
  --k3s-arg "--disable=servicelb@server:0" \
  --no-lb \
  --wait

Make sure you can connect to it

kubectl cluster-info

Prep

Get the inlets pro license from their site

For this demo we'll be using Digital Ocean. Get a personal access token from your control panel.

Install

Create the namespace and install the license and inlets-access-key secrets

kubectl create namespace inlets

kubectl create secret generic -n inlets \
  inlets-license --from-literal license=<inlets license key>

kubectl create secret generic -n inlets \
inlets-access-key \
--from-literal inlets-access-key=<digital oceano personal access token>

Install the inlets-operator using helm

helm repo add inlets https://inlets.github.io/inlets-operator/
helm repo update && \
  helm upgrade inlets-operator --install inlets/inlets-operator \
  --namespace inlets \
  --set region=lon1

Test

Install nginx

kubectl apply -f nginx.yaml

Get the service IP address

kubectl get svc -n demo1

You should see the Welcome to nginx! page.

Codezero

Follow the codezero getting started guide: https://docs.codezero.io/guides/getting-started

Consume the nginx service

czctl compose start -f cz-nginx.yaml

Test

curl http://nginx/

Will return the Welcome to nginx! page
