Preparation

Before you start, be sure that:

• You have a working KUBECONFIG. Try running kubectl get pod and make sure there are no errors
• Know what namespaces you have access to. kubectl config get-contexts will show your current namespace.

Get the example deployment files

All the files used to build the demo are on GitHub at patricklang/fabrikamfiber. We'll clone that repo, but instead of building everything from scratch we'll just modify and use the Kubernetes deployment YAML there. Since we're not building the Windows container, these steps work great on any platform with a kubectl build. Nothing else is needed.

If you're using the Lab VM at Kubecon, first open a PowerShell window with the >_ icon on the taskbar, then clone the repo

cd \repos
git clone https://github.com/PatrickLang/fabrikamfiber.git

Change to the k8s directory where the deployment files are.

Run code . to open them in Visual Studio Code.

There are 5 files that are used:

• db-secret.yaml - shared secret for the database password
• db-mssql-linux.yaml - the database deployment
• db-service.yaml - the database service. this is needed so the website can find it by name
• fabrikamfiber.web-deployment.yaml - the website deployment
• fabrikamfiber.web-ingress.yaml - an internal service and external ingress rule
  • (If you're doing this on your own, you may prefer fabrikamfiber.web-loadbalancer.yaml to use a loadbalancer instead of ingress controller)

Modify fabrikamfiber.web-ingress.yaml, and change the first part of host: rascally.test.ogfg.link to something unique. Make sure it ends with .test.ogfg.link for the Kubecon lab since that's the preconfigured ingress controller.

Here's what the full file will look like:

apiVersion: v1
kind: Service
metadata:
  labels:
    app: fabrikamfiber.web
  name: fabrikamfiberweb
spec:
  ports:
  - port: 80
  type: "ClusterIP"
  selector:
    app: fabrikamfiber.web
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: nginx
  name: fabrikamfiberweb-ingress
spec:
  rules:
    - host: rascally.test.ogfg.link
      http:
        paths:
          - backend:
              serviceName: fabrikamfiberweb
              servicePort: 80
            path: /

After you've set a unique hostname, run kubectl create on each of those files:

kubectl create -f .\db-secret.yaml
secret/mssql created

kubectl create -f .\db-mssql-linux.yaml
deployment.apps/db created

kubectl create -f .\db-service.yaml
service/db created

kubectl create -f .\fabrikamfiber.web-deployment.yaml
deployment.apps/fabrikamfiber.web created

kubectl -n rascally create -f .\fabrikamfiber.web-ingress.yaml
service/fabrikamfiberweb created
ingress.extensions/fabrikamfiberweb-ingress created

Once that's done, check the status and wait for the pod to be Running
