How do you create and deploy an Akka application using Docker and/or Kubernetes, and what benefits does this bring to the project?
To create and deploy an Akka application using Docker and Kubernetes, follow these steps:
1. Develop the Akka application with a suitable build tool (e.g., sbt or Maven).
2. Create a Dockerfile to package the application into a container image.
3. Build the Docker image using docker build command.
4. Push the built image to a container registry (e.g., Docker Hub or Google Container Registry).
5. Write a Kubernetes deployment YAML file referencing the pushed image.
6. Apply the deployment using kubectl apply -f <deployment-file.yaml>.
Benefits of this approach include :
* Isolation : Containers encapsulate dependencies, ensuring consistent runtime environments.
* Scalability : Kubernetes can scale applications based on demand, improving resource utilization.
* Resilience : Kubernetes monitors and restarts failed containers, enhancing fault tolerance.
* Rolling updates : Deployments enable zero-downtime updates, minimizing disruption to users.
