Installing Kubernetes on CentOS


{{ vExpose }}.Blog

Part of my job is to talk about latest geeky technologies and many a times I also have to demonstrate the same – Kind of “Show me” discussions.

When I started working on getting my hands dirty on Kubernetes (aka K8S) I faced many issues to get started. Now I am at the level where deploying K8S isn’t a big deal at all. Reason I am writing this blog is because often more than not I always get into discussions where someone is just starting with K8S journey and has the same queries and questions which I also had. Hopefully this summary will help people to getting started with K8S.

Before I get stared it’s important to understand the K8S lingo :) This will help understand the implementation steps. Also note that purpose of this page is not to re-iterate the K8S components and architecture. It’s purely intended to list…

Containers are everywhere and they are here to stay. They are great level-playing ground to break the infrastructure dependency and allow developers to release their code to any environment.

Containers also help customers to operate at greater scales with ability to quickly scaling up and down, patching with disruptions, withstand infrastructure component failures, moving easily from on-premises to public clouds, etc.

As per the survey from sysdig lifespan of containers and container images is also very short.

At this stage of the popularity of containers there are two thought processes in the container fan club – Persistent or Non-Persistent Containers

If you explore docker hub top downloads you’ll notice that 7/10 top downloads require data persistence (snippet below)

Let’s understand persistent containers in more details.

Prior to Container Storage Integration CSI, Kubernetes provided in-tree (ie as part of the core code) plugins to support volumes but that posed a…
