Kubernetes

  Let’s see what is Kubernetes? In simple language, Kubernetes is an open source tool for automating container deployment, scaling, and management. Google open-sourced the Kubernetes project in 2014. Kubernetes combines over 15 yrs of experience of google running production workloads at scale with best-of-breed ideas and practices from the community. Why we need Kubernetes and what it can do? Containers are a good way to bundle and run your applica t ions. In a production environment, you need to manage the containers that run the applications and ensure that there is no downtime. For example, if a container goes down, another container needs to start. Wouldn’t it be easier if this behavior was handled by a system? That’s how Kubernetes comes to the rescue! Kubernetes provides you with a framework to run distributed systems resiliently. It takes care of scaling and failover for your application, provides deployment patterns, and more. For example, Kubernetes can easily manage ...

 We can achieve the following task with the help of editing Routing table, For editing the Routing table we have to use the command #Route -n This route table gives information about Destination, Gateway and etc now in this we can remove the basic IP and add google IP Now to look for google ip we can use nsloopup command , 172.217.166.0 is the ip of google Now we can try pinging google.com, since we've added we'll be able to ping Now we won't be able ping facebook because we've removed the default rules and added only google

I've listed out all the deep dive concepts that I've learnt from the session * CVS is a Centralized Version Control System and it is used to store code in one centralized version. * Git preferred over CVS because Git offers much more tools than CVS. It has branching capabilities. Unlike centralized version control systems, Git branches are cheap and easy to merge. Git is faster to commit. * We need a different environment in production because multiple teams can look up to different subproblems and functionalities at the same time thus achieving goals in less time. * Global Traffic manager applies an Internet-centric approach to global load balancing to provide high site availability and responsiveness to online user requests. * Chaos testing is simply creating the capability to continuously, but randomly, cause failures in your production system. * CPU request refers to a request made for using CPU resource by application, CPU limit refers as it will limit the resource access ...

Here are some of the things that i've learnt from the expert session by redhat What are the benefits and challenges of K8 i.e Benifits --->Scalability, workload Probability, stability vs speed argument   What are a Container and mention the problems associated with it i.e Container are nothing but just a process or program or it can also termed as operating system. Challenges in pods are we'll have to keep on eyes on container, if any of the container goes down so we have to again launch Difference between Virtual Machine and Containers i.e in VM only the hardware is shared but in Containers both hardware and kernel is shared How docker represents as a Service Platform What are Openshift and mention its features i.e Pod autoscalling,High availability,Choice of cloud infrastructure,Response web consol,operator hub,CI/CD,service mesh,Server less and S2I service etc How application platform changes What is the platform as a service What is S2I What is Service Mesh What is Podm...
