Personal cloud for sideprojects with kubernetes (6 Part Series)
As the final step in this long series of blogposts we are going to deploy a simple webapp in a docker container to my personal cloud. For context here is the personal cloud setup with Traefik/Let's Encrypt (Run a personal cloud with Traefik, Let's encrypt and Zookeeper).
In previous blogposts I also described how I built the app (Build a PWA in docker).
The deployment runs the docker container. If you follow my personal cloud setup make sure to use more than one replica as the nature of preemtive VMs means one replica might randomly get shut down.
Note that the image will be set and updated by gitlab ci as described here: (Deploy to google kubernetes engine using gitlab ci).
kind: Deployment apiVersion: extensions/v1beta1 metadata: name: ???-app spec: replicas: 3 template: metadata: labels: app: ???-app spec: terminationGracePeriodSeconds: 60 containers: - name: ???-app image: "eu.gcr.io/???/app:latest"
apiVersion: v1 kind: Service metadata: name: ???-app spec: selector: app: ???-app ports: - name: web port: 80 targetPort: 80 --- apiVersion: extensions/v1beta1 kind: Ingress metadata: name: ???-app annotations: kubernetes.io/ingress.class: traefik traefik.frontend.passHostHeader: "false" traefik.frontend.priority: "1" spec: rules: - host: app.???.com http: paths: - path: / backend: serviceName: ???-app servicePort: web
Updating the traefik config is important so traefik requests a new HTTPS certificate for the app from Let's encrypt. You will need to add this line to the traefik toml file that is described here (Run a personal cloud with Traefik, Let's encrypt and Zookeeper):
[[acme.domains]] main = "app.???.com"
Now you can just point the A record of your domain to the traefik external IP and the rest will automatically be handled by your personal cloud :).
