Experts Session on Industry use case of OpenShift


Hello every one, here’s a small article about a session I attended of Redhat on the Industry use case of Kubernetes and OpenShift.

It was a great opportunity for me to attend a webinar, which was delivered by Mr Amel Mathai (Technical Delivery Manager, Redhat Training, world’s First Ansible certified professional), Mr Daleep Singh Bais (Senior Technical Instructor, RedHat Technologies) and Abid Mattoo sir(Partner Sales Manager).

Here are some key points that I learnt in this session:

  • Kubernetes Provide lot’s of benefits like scalability, stability, workload, portability, etc. And the challenges of Kubernetes are deployment, operations, hardening.
  • Using Containerization we can launch a new OS in just 1 sec and using the resource like RAM/CPU of base OS. And That OS called a container. And the problem associate with that container is no one monitor their actions.
  • Docker Represents As A Service Platform: Build → Ship → Run
  • Openshift is an open-source container application platform provide by RedHat and based on a Kubernetes container orchestration for CI/CD pipeline and application development. There are lots of the feature of Opensift like pod auto-scaling, High Availability, Operator Hub, CI/CD, Choice of cloud infrastructure, etc...
  • Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.
  • Podman is a fully featured container engine that is a simple daemon less tool. It eases the transition from other container engines and allows the management of pods, containers and images
  • Containerized applications share an operating system environment (kernel) so they use fewer resources than full virtual machines and reduce pressure on the host’s memory. This is one of the advantages of container technology over the Virtualization VM
  • Source To Image (S2I) is a tool or framework using that we can easily make or write images and that source code from GitHub and deploy this in it.
  • For Security purpose, we use a service mesh tool and it is managing the internal server to server communication.

I would hereby like to thank Mr Vimal Daga Sir & Mrs Preeti Daga Ma’am and the whole Linux World team for arranging such an informative and great expert’s session it was a pleasure to learn about real industry use cases about K8s and open shift.

How to configure Hadoop cluster using Ansible playbook

Image
  Automation is the new future of today's industry now most of the industry is heading towards automation as it reduces human efforts and errors which can be performed by humans also will be reduced. Nowadays companies have to configure a large number of servers daily and doing manually every server is not practically possible and time-consuming as well and today's era we don't have time to waste for this so we have to need some automation tool which performs all the task in every server in a single click and one of the automation tool is Ansible. First, let's talk about what is Hadoop Apa c he Hadoop is open-source software that provides us with the facility to build our own distributed storage cluster and computing cluster by Hdfs and Mapreducers programming methods. So what is the Hadoop cluster? Hadoop cluster is a very great program which allows us to join many storages of the data node and give as single storage to the client creating an illusion that the client h...

Automation Using Python Menu-Driven Program

  Automation is the key to the future, as in industry we don't want any delay in providing service to the client and the implementation of automation technologies, techniques and processes improve the efficiency, reliability of many tasks that were previously performed by humans manually. Today almost all the organization are using automation in their system and keeps on increasing on daily basis both in the software/hardware and machine layer. In this article, we will see how automation reduces human effort and how the menu-driven program functions.

Configuring HAProxy using Ansible playbook

Image
Configuration Management  is the most important task, mostly task belonging to configuring different types of web servers with a different use-case and mostly in the industry, we have normally millions of webservers running behind the scene and manually configuring every webserver is practically not possible so the only key is automation. In this article, we would be configuring 1 system as Haproxy and 2 systems as a webserver using Ansible automation. So what is HaProxy? HAProxy is software that provides 2 services in a single packet, which stands for High Availability Proxy, It acts as a load balancer that helps in balancing the load between web servers and it also acts as a Reverse Proxy which improves the security of the webservers. So let's start with updating the Inventory file I  h ave created my inventory on the “ /root/ip.txt”  location of the Controller Node, and it will mainly consist of few details about  Target Node. vim /root/ip.txt Here I have created ...
