Install Kind (Kubernetes in Docker)
-
Create a kind cluster
- Pull the kind image:
docker pull kindest/node:v1.25.2@sha256:9be91e9e9cdf116809841fc77ebdb8845443c4c72fe5218f3ae9eb57fdb4bace - Then run:
kind create cluster --config ./kind-cluster-config.yaml
- Pull the kind image:
-
Build the docker image at the root folder of the project with
docker build . -t learnk8s/challenge:0.1.0 -
Add the build image to kind:
kind load docker-image learnk8s/challenge:0.1.0 -
Run:
helm repo add bitnami https://charts.bitnami.com/bitnami -
Run:
helm repo add apisix https://charts.apiseven.com
In charts/apisix folder, run:
helm dependency updatehelm upgrade --install -n ingress-apisix --create-namespace ingress-apisix .
Verify your installation created 5 services: kubectl get service --namespace ingress-apisix
In charts/hello folder, run:
helm upgrade --install -n hello --create-namespace hello .
Verify your hello pod is running: kubectl get pod --namespace hello.
You should see a status "Running" in the output.
Note that the API KEY is the default one, it is not intented for production usage.
kubectl -n ingress-apisix exec -it $(kubectl get pods -n ingress-apisix -l app.kubernetes.io/name=apisix -o name) -- curl "http://127.0.0.1:9180/apisix/admin/routes" -H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1"
Run:
kubectl exec -it $(kubectl get pods -n ingress-apisix -l app.kubernetes.io/name=apisix -o name) -- curl http://127.0.0.1:9080/ -H 'Host: localhost'
Expected output: Hello Nmaxime!
Get the kind-worker node IP:
WORKER_IP=$(kubectl get no kind-worker -o jsonpath='{.status.addresses[0].address}')
Get the node port of the API gateway service:
GATEWAY_PORT=$(kubectl get svc ingress-apisix-gateway -o=jsonpath='{.spec.ports[0].nodePort}')
Then verify you get the Hello Nmaxime! response from the hello service:
curl $WORKER_IP:$GATEWAY_PORT/ -H "Host: localhost"
