Camel Kubernetes

Running the tests

This component contains unit and integration tests. Some of them - like the consumer ones - require a Kubernetes environment.

Running using Kind

It is possible to run the integration tests using Kind. To do so, follow these steps:

1. Create a cluster:

kind create cluster

2. Set the default namespace to work with (optional):

kubectl config set-context --current --namespace=default

3. Create a ServiceAccount and Secret:

kubectl create serviceaccount camel

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Secret
metadata:
  name: camel-token
  annotations:
    kubernetes.io/service-account.name: camel
type: kubernetes.io/service-account-token
EOF

4. Get the auth token:

export KUBE_TOKEN=$(kubectl get secrets -o jsonpath="{.items[?(@.metadata.annotations['kubernetes\.io/service-account\.name']=='camel')].data.token}"|base64 --decode)

5. Get the host:

export KIND_PORT=$(docker inspect --format='{{range $p, $conf := .NetworkSettings.Ports}}{{(index $conf 0).HostPort}}{{end}}'  kind-control-plane)
export KUBE_HOST=https://localhost:$KIND_PORT

6. Run the test:

mvn -Dkubernetes.test.auth="$KUBE_TOKEN" -Dkubernetes.test.host=$KUBE_HOST -Dkubernetes.test.host.k8s=true clean verify

Running using Minikube

It is possible to run the integration tests using Minikube. To do so, follow these steps:

1. Create a cluster:

minikube start

2. Get the auth token:

export KUBE_TOKEN=$(kubectl get secrets -o jsonpath="{.items[?(@.metadata.annotations['kubernetes\.io/service-account\.name']=='default')].data.token}"|base64 --decode)

4. Get the host:

Find out the URL where the control plane is running:

kubectl cluster-info

And then set that as export, for example:

export KUBE_HOST=https://127.0.0.1:50179

5. Run the test:

mvn -Dkubernetes.test.auth="$KUBE_TOKEN" -Dkubernetes.test.host=$KUBE_HOST -Dkubernetes.test.host.k8s=true clean verify
