K1s Landingpage

K1s is the 1st Kubernetes Serverless Cluster Simulator, and this is the landing page repo

How to run the container in Kubernetes?

Based on the docker-compose file:

#docker-compose-k8s.yaml
version: "3.9"
services:
  k1s-lp:
    container_name: k1s-lp
    image: adrianescutia/landingpage
    restart: unless-stopped
    env_file: $PWD/.env
    volumes:
      # Getting error if mounting this folder, had to create as mounted volumes
      - app_public:/usr/local/apache2/htdocs/
    ports:
      - "3000:80"

volumes:
  app_public:
    driver: local
    driver_opts:
      type: none
      device: $PWD/public-html
      o: bind

Remember to rename the dotenv example to .env and set the values (optional), file has some dummy values.

If you need to override the .env file:

docker compose --env-file ~/.env-landingpage --project-name k1s-landingpage up -d

Default .env:

docker compose --project-name k1s-lp up -d

Deploy in Kubernetes instead?

  1. Install kompose.
  2. In the directory where your docker-compose.yaml is, run:
    kompose convert

Apply the generated file, describe the service and check the NodePort port.

kubectl apply -f k1s-lp-service.yaml

Util commands

kubectl describe service k1s-lp | grep NodePort | awk '{print $3}' | cut -d'/' -f1 | xargs -I {} echo "http://localhost:{}"
# get the cluster IP with kubectl cluster-info
kubectl cluster-info | grep 'control plane' | awk '/http/ {print $NF}' | sed 's/\x1b\[[0-9;]*m//g'
# get the pod labels
kubectl get pods --show-labels
# get the deployment name from the k1s-lp-service.yaml
kubectl get pods -l io.kompose.service=k1s-lp -o jsonpath="{.items[0].metadata.name}"

Copy the landing page index.html and the .env to the cluster:

./copy_files.sh your-namespace your-deployment
