- A running kubernetes cluster (if you don't have one see Setup a local cluster section)
- helm 3 installed on your machine
- skaffold installed on your machine
Than we can create a two nodes cluster (one master and one worker):
cat <<EOF | kind create cluster --config=-
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
- role: worker
EOF
and activate the kubectl
config via:
kind export kubeconfig
Replace also the domain name to use in hack/test/example-ingress.yaml
from kubernetes.localhost
to your domain (ensure also that the subdomain example1
and example2
are resolved to the server public IP)
Create a namespace to host the caddy ingress controller:
kubectl create ns caddy-system
Than we can start skaffold using:
skaffold dev --port-forward
this will automatically:
- build your docker image every time you change some code
- update the helm release every time you change the helm chart
- expose the caddy ingress controller (port 8080 and 8443)
You can test that all work as expected with:
curl -H 'Host: example1.kubernetes.localhost http://127.0.0.1:80/hello1
curl -H 'Host: example1.kubernetes.localhost http://127.0.0.1:80/hello2
curl -H 'Host: example2.kubernetes.localhost http://127.0.0.1:80/hello1
curl -H 'Host: example2.kubernetes.localhost http://127.0.0.1:80/hello2
- You can change local port forwarded by skaffold by changing the port values in the
skaffold.yaml
file on sectionportForward
localPort
. Remind that you can forward only port greather than 1024 if you execute it as non root user - You can delete your local cluster with the command
kind delete cluster
- To use TLS your domain should be publically resolved to your cluster IP in order to allow Let's Encript to validate the domain
