Kubernetes cluster provisioning in lxc

Kubernetes:

Kubernetes is a portable, extensible open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.

Linux Containers

LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it allows Linux users to easily create and manage system or application containers.

Features of LXC:

->Kernel namespaces

->Apparmor and SELinux profiles

->Seccomp policies

->Kernel capabilities

->Cgroups

LXC containers are often considered as something in the middle between a chroot and a full-fledged virtual machine. The goal of LXC is to create an environment as close as possible to a standard Linux installation but without the need for a separate kernel.

Why Kubernetes in LXC?

Kubernetes is a large tool in managing containers it requires more configuration and specifications. Linux containers are light weighted but they use the host machine kernel to work.

Due to this reason, the LXC containers are customizable according to Kubernetes required configuration.

LXC and LXD

LXD is an open-source container management extension for Linux Containers (LXC). ... LXD also supplies a system daemon that applications can use to access.

LXC and has a template distribution system to enable faster container creation and operation.

Objective

To provision a Kubernetes cluster on top of Linux containers (LXC)
