Lab 10.1

I was trying to follow the lab but I kept getting a 404 on downloading the traefik daemonset
$ wget https://tinyurl.com/yawpexdt -O traefik-ds.yaml
A bit of googling later I found the manifest here: https://gist.github.com/tasdikrahman/1f9f496dec39c2a5697bf9a50276c7c4 (hopefully it is the same one as the tinyurl was pointing to)

Unfortunately, when I tried to apply the ingress rule, I ran into an error.
$ kubectl create -f ingress.rule.yaml error: error validating "ingress.rule.yaml": error validating data: [ValidationError(Ingress.spec.rules[0].http): unknown field "path" in io.k8s.api.extensions.v1beta1.HTTPIngressRuleValue, ValidationError(Ingress.spec.rules[0].http.paths[0]): unknown field "serviceName" in io.k8s.api.extensions.v1beta1.HTTPIngressPath, ValidationError(Ingress.spec.rules[0].http.paths[0]): unknown field "servicePort" in io.k8s.api.extensions.v1beta1.HTTPIngressPath, ValidationError(Ingress.spec.rules[0].http.paths[0]): missing required field "backend" in io.k8s.api.extensions.v1beta1.HTTPIngressPath]; if you choose to ignore these errors, turn validation off with --validate=false

Here is the content of the ingress.rule.yaml
apiVersion: extensions/v1beta1 kind: Ingress metadata: name: ingress-test annotations: kubernetes.io/ingress.class: traefik spec: rules: - host: www.example.com http: paths: - backend: serviceName: secondapp servicePort: 80 path: /
