Docker container basics and efficiency of Kubernetes
- 1. Md. Armanuzzaman Akhter Al Amin Md. Shakil Zaman Docker container basics and efficacy of Kubernetes regarding container management

- 4. | 4 Docker Components Docker Docker Client and Server Docker Images Docker Container Docker Registries
- 5. | 5 Docker Architecture Docker Networking image source: https://docs.docker.com/engine/docker-overview/
- 7. | 7 What if we have Microservice system like this? For n number of μ-service container, I have to run and stop containers by hand? Container 1 Container 2 Container 3
- 8. | 8 Docker Compose One YML file solves multi container problem Compose files typically are like this: version: '3' services: service 1: build: . ports: - "5000:5000" service 2: build: . ports: - "5001:5001" redis: image: "redis:latest" rabbitMQ: image:"rabbitMQ:latest" Service based Scaling problem fixed….

- 10. Features of Docker Swarm • Cluster management integrated with Docker Engine • Decentralized design • Scaling • Desired state reconciliation • Load balancing • Secure by default
- 11. | 11 Dockerhub These are the steps of deployment cycle where Dockerhub comes into play image source: https://trishnag.wordpress.com/2016/04/28/publish-docker-image-with-automated-build/

- 13. | 13 Advantage of Docker Container ● Speed ● Portability ● Scalability ● Rapid Delivery ● Density
- 14. | 14 Disadvantage of Docker Container ● Security concern ● Dependency on Operating system ● Not compatible with older machines ● Difficult to manage
- 15. Kubernetes • Cluster management Tool • Decentralized design • Scaling • Desired state reconciliation • Load balancing • Secure by default Isn’t this the same thing we saw for Docker Swarm?
- 16. | 16 Yes it is... ▪ Robustness, Maturity and Community Support ▪ Autoscaling ▪ Self healing ▪ GUI available ▪ Built-in Logging and Monitoring tool ▪ Example: Pokemon Go saved by K8s
