Building and Managing Kubernetes with Kubernetes: Kubernetes as a declarative and portable system can be used to do many things in different ways.

Kubernetes as a declarative and portable system can be used to do many things in different ways.

At eBay we built a fleet management system based on k8s. Everything(server, subnet, OS, package and state) is declarative and can be modeled as CRDs in k8s, or referred to as a commit id in git from the objects. By running various controllers on top of these CRD objects, we use k8s to manage k8s, and the entire eBay data center. - Our system provisions hosts the same way k8s creates and manages pods. - We build k8s clusters with Salt. each host has a set of states defined in its salt CRD object. controllers pull states from git based on commit ids to apply. - We build both schedulers and deployment transactions to manage the k8s clusters for both config deployments and upgrades. This declarative, highly scalable, auto healing, and cloud native system is what we think can unify eBay’s fleet.

Kubernetes Vs Docker

Kubernetes Vs Docker

This video on "Kubernetes vs Docker" will help you understand the major differences between these tools and how companies use these tools.

We will compare Kubernetes and Docker on the following factors:

  1. Definition
  2. Working
  3. Deployment
  4. Autoscaling
  5. Health check
  6. Setup
  7. Tolerance ratio
  8. Public cloud service providers
  9. Companies using them

Scaling Node.js Applications with Kubernetes and Docker

Scaling Node.js Applications with Kubernetes and Docker

Scaling Node.js Applications with Kubernetes and Docker. We will explore the benefits of DevOps process using Kubernetes, Docker, and Node.js. Learn about the basics of Kubernetes and tips to scale Node.js Applications. Learn the common problems that we face when we decide to change from monoliths to microservices using Docker and JavaScript.

We will explore the benefits of DevOps process using Kubernetes, Docker, and Node.js. Showing how Docker and Node.js can work together, using the power of Kubernetes to release and to scale automatically stateless services. At this talk we will explore the key concepts and components to start working with Kubernetes, real scenarios and the differences between the traditional approach compared to Container based applications. Attendees will learn about the basics of Kubernetes and tips to scale Node.js applications furthermore they will learn the common problems that we face when we decide to change from monoliths to microservices using Docker and JavaScript.

What are the key takeaways from this talk?

  • Service communication
  • Kubernetes and Docker,
  • High availability & release process

What is the difference between Docker, Kubernetes and Docker Swarm ?

What is the difference between Docker, Kubernetes and Docker Swarm ?

What is the difference between Docker and Kubernetes? And Kubernetes or Docker Swarm? In my video "Docker vs Kubernetes vs Docker Swarm" I compare both Docker and Kubernetes and Kubernetes vs Docker Swarm.

In my video "Docker vs Kubernetes vs Docker Swarm" I compare both Docker and Kubernetes and Kubernetes vs Docker Swarm.

Kubernetes and Docker are not competing technologies. In fact, they actually complement one another to get the best out of both. In contrast, Docker Swarm is the comparable technology to Kubernetes.
