Kubernetes has good features to let you revert your deployments back with a simple command. If you have
ever heard following scenario within your company before, this session will be the medicine for you.
“Payment microservice is in an unstable state after last deployment, what we can do?”
“I realized that Cart service has incorrect version during the deployment is in half state, I need to revert them back…”

Beside some theoretical information, we will apply some production-ready dojos. The outline will be;

  • What is Ingress?
  • Ingress Strategies
  • Ingress Operations on Production Environment
  • Isolated and Non-Isolated Pods with Network Policies

If you plan to extend your from personal one to enterprise one, you need to apply some authorization rules to restrict some operations according to needs. In this session, you will see a do a kubernetes dojo especially for authorization and secret management.

If you are using Google Kubernetes Engine, it is a piece of cake. I have upgraded machine types from n1-standard-1 to n1-standard-2 for all of the kubernetes cluster nodes and you can see my adventure in following video.

Kubernetes lets us create and manage these configurations in several ways. Additionally, we need to share application specific data in a clustered environment on cloud or on premise. In this webinar, you can see kubernetes dojo for production ready cases.

Some of the topics covered are below;

- Creating Deployment
- Single and Multi-Container Concept in Deployment
- Monitoring, Debugging Pods
- Service Types
- Exposing Services to Internet
- Manage Environment Variables of Deployment
- Service-to-Service Communication

You can see schedule below;

  1. Create machines by using Docker Machine to use as Kubernetes cluster nodes
  2. Install kubernetes cluster with 1 master 2 slave nodes
  3. Install and configure kubectl to apply some operations on cluster
  4. Review cluster components to have a good insight about kubernetes
  5. Deploy a Spring Boot app on to cluster

In this demo, I provided lots of cool features about Tyk which is an open source API Gateway contains API Gateway, simple to use API Management Dashboard, API analytics and developer portal. Happy watching…

The main concept was Microservices with Node.js dispatched by another Node.js application with service discovery backed by MongoDB. All the requests dispatched by dispatcher will be synchronized to Elasticsearch. By doing this, all the logs will be analyzed on Kibana and will be able to monitor by providing threshold to api requests.
