Example of emptyDir volume sharing between two containers within a Pod. A file will be created with the current timestamp by the producer and the consumer is a web server which is reading the file every second.
Through Server Sent Events and a basic web page the current value is show to the user and pushed on every change.
Within the root folder simply run:
docker-compose up --build --detach consumer producerThe web server can now be reached through localhost:8080.
To shutdown the system run following command:
docker-compose down- Build both container images by running following commands from the root folder:
docker build -t consumer:latest consumer/.
docker build -t producer:latest producer/.Apply the provided manifest files within the k8s folder:
kubectl apply -f k8s/Forward the port to the created service:
kubectl port-forward svc/k8s-emptydir 8080:8080The web server can now be reached through localhost:8080.
To shutdown the system run following command:
kubectl delete -f k8s/
