So, have you decided that Kubernetes is the best open-source platform to use for managing containerized workloads and services for your business? Then good for you! After all, this platform has not become the de facto standard to run these containers for no reason. It has a broad ecosystem with a variety of services, support systems, and tools that you can use to facilitate declarative configuration and automation. However, the “why” is different than the “how”. After you have chosen this platform, you should also know how to manage Kubernetes on-premise to get the most out of its functions.
In a recent post by Kublr, they state that Kubernetes supports stateless deployments and stateful deployments. Aside from being run on the cloud, many companies run and manage it on premise, as they observed it is easier this way.
For starters, you should know the different options to set up and run this platform. Different solutions require different requirements. You can experience different levels of control and security, as well as available resources to operate and manage a cluster.
When running Kubernetes on a local machine, you will have multiple options for entry points. These include Docker in Docker, Minikube, Microk8s, and k3s.
- Docker in Docker
This is from the Kubernetes-sigs project that is known as the kubeadm-dind-cluster. When using this option, you should create three Docker containers, two worker nodes, and one master.
However, according to Kublr, there has been confusion about how Kubernetes and Docker relate to one another. Some are asking if you really need Docker when running Kubernetes. Well, it actually depends on the complexity of the system you are dealing with. It is recommended to use Docker if you are running a really complex platform.
This is a popular entry point for most people who are still learning to use Kubernetes. This is even considered to be the fastest way to get the platform running on laptops. However, remember that it only has one worker node, is one machine with relays for virtualization, and has only 2GB by default to use. You are able to run typical commands on it, but not stock Kubernetes.
Supported by Ubuntu’s Canonical, this is a simple snap installation solution for Kubernetes. Basically, it is a quick way to get a cluster up and running. One oddity of this option, though, is each of its command is prefixed.
Supported by Rancher Labs, this is one of the newest ways to get a Kubernetes cluster on a local machine. However, this is designed only for small environments, such as the Internet of Things (IoT) and edge computing.
Before you deploy, run, and manage Kubernetes on-premise, you should be familiar with these options first. Doing so will allow you to get the most out of this platform.
Evaluate a solution for your production environment
You should determine which aspects of operating a Kubernetes cluster you want to run and manage. These include, but not limited to, the data plane, applications, control plane, cluster operations, and cluster infrastructure.
Know these possible abstractions and whether they can be managed on your own or should be managed by the provider.
