Expert session on Openshift and Kubernetes
The Session on Industry use cases of Kubernetes and Openshift was a great session which was mainly about how Openshift is an on-premises platform as a service built around containers orchestrated and managed by Kubernetes on a foundation of Red Hat Enterprise Linux along with practical demonstrations
The Session was delivered by Mr. Amel Mathai, Technical Delivery Manager, RedHat Training — India/South Asia, RedHat, Mr. Daleep Singh Bais, Senior Technical Instructor, RedHat and Mr. Abid Matto, Partner Sales Manager at RedHat (GLS), RedHat.
Thing that I learnt from the session:
Containerization better thenVirtualization:
- Containers are a lighter-weight, more agile way of handling virtualization
- Rather than launching the entire virtual machine, a container gathers all of the components necessary to operate a single piece of software.
Kubernetes -
It is a container orchestration engine for automating deployment, scaling, and management of containerized applications
Benefits of kubernetes:
1. Scalability
2. Workload Portability
3. Stability vs Speed arguments
Challenges of K8s:
1. Deployment
2. Hardening
3. Operations
Openshift -
Red Hat OpenShift is an open-source container application platform based on the Kubernetes container orchestrator for enterprise application development and deployment
Openshift features :
- Pod autoscaling
- High Availability
- Responsive Web Console
- Rich Command-line toolset
- IDE Integration
- CD/CD
S2I (Source to Image) -
- Source-to-Image (S2I) is a framework in openshift that makes it easy to create images that take application source code as an input and produce a new image that runs the assembled application as output
Podman:
Podman is a fully featured container engine that is a simple daemonless tool. Podman provides a Docker-CLI comparable command line that eases the transition from other container engines and allows the management of pods, containers and images
Finally, I would like to Thanks to Mr. Vimal Daga Sir, Preeti Chandak Ma’am and LinuxWorld Informatics Pvt Ltd , Amel Mathai , Daleep Singh Bais (RHCA Level VIII, RHCI, RHCVA, CKA) and Abid Matoo for arranging such great session.
