Extra deployments to finish off your kubernetes installation on Docker-for-Desktop deployments
After enabling Kubernetes in the Docker-for-Desktop preferences, you will have a basic kubernetes setup running locally on your docker instance. It does not however deploy the kubernetes dashboard, or any Ingress Controller / Service.
These additional steps will
- deploy the Traefik Ingress Controller,
- expose the Traefic Admin Console,
- deploy the kubernetes dashboard,
- configure an Ingress service to expose the kubernetes dashboard
From your prompt, ensure your kubernetes cluster is running kubectl cluster-info
Deploy Traefik by running:
$ kubectl create -f https://github.com/devops-consultants/kubernetes-for-desktop/raw/master/traefik-rbac.yaml
$ kubectl create -f https://github.com/devops-consultants/kubernetes-for-desktop/raw/master/traefik-deployment.yaml
Once the traefik pod has finished deploying, you can confirm what ports the Traefik Ingress Service is listening on by running:
$ kubectl get svc -n kube-system traefik-ingress-service
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
traefik-ingress-service NodePort 10.109.59.180 <none> 80:31581/TCP,8080:30417/TCP 15h
In this example, the ingress service is exposed on port 31581 and the admin console on 30417 - check you can view the current Ingress configuration by going to http://localhost:adminPort/ ie. http://localhost:30417/
Deploy the dashboard by running:
kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
After deploying the dashboard, we need to make a small modification to the definition of the kubernetes-dashboard service, giving the port the name 'https'. This is so that Traefik knows to use a https connection from the Ingress Controller to the dashboard deployment.
kubectl apply -f https://github.com/devops-consultants/kubernetes-for-desktop/raw/master/kubernetes-dashboard-service.yml
This ingress rule assumes that we are using a hostname of k8s.local to access the local kubernetes installation on Docker-for-Desktop. Add the following to your /etc/hosts file:
127.0.0.1 k8s.local
As an example of ingress rules, the following will also add an ingress rule to the Traefik admin console. Run:
kubectl create -f https://github.com/devops-consultants/kubernetes-for-desktop/raw/master/dashboard-ingress.yml
You should now be able to access:
