CoreOS is an exciting Linux distribution focused on getting clustered environments up and running quickly. By leveraging technologies like Docker containers and service discovery, CoreOS clusters can be easily managed as a single unit. In this guide, we will discuss some of the background technologies that make CoreOS possible.

CoreOS Training in Bangalore

CoreOS is pre-configured with popular tools for running Linux containers. Containers are like extremely lightweight VMs – they allow code to run in isolation from other containers but safely share the machine’s resources, all without the overhead of a hypervisor. Containers can boot extremely fast (in milliseconds!) which gives you unprecedented flexibility in managing load across your cluster. For example, instead of running chef on each of your VMs, it’s faster and more reliable to have your build system create a container and launch it on the appropriate number of CoreOS hosts. When these containers start, they can signal your proxy (via etcd) to start sending them traffic.

Features

  • Container runtimes are automatically configured on each CoreOS machine
  • Updated with regular automatic OS updates
  • Integrates with etcd
  • Networking automatically configured

Course Outline

An Introduction to CoreOS System Components

CoreOS is an exciting Linux distribution focused on getting clustered environments up and running quickly. By leveraging technologies like Docker containers and service discovery, CoreOS clusters can be easily managed as a single unit. In this guide, we will discuss some of the background technologies that make CoreOS possible.

 

How To Set Up a CoreOS Cluster

If you are planning on using CoreOS in your infrastructure, the first thing you will want to set up is a CoreOS cluster. In order for CoreOS machines to form a cluster, their etcd2 instances must be connected.

 

How To Use Fleet and Fleetctl to Manage your CoreOS Cluster

The fleet daemon and the fleetctl utility program are essential for managing your CoreOS cluster. A cluster-wide interface to individual systemd instances, this system allows you to manage services throughout your clustered environment.

 

How To Use Etcdctl and Etcd, CoreOS’s Distributed Key-Value Store

Etcd is a globally distributed key-value store that forms the basis of the clustering technology in CoreOS. In this guide, we’ll look at etcd and the etcdctl utility and discuss how they can be used to store and retrieve application and cluster data.

 

How To Create and Run a Service on a CoreOS Cluster

CoreOS enables cluster-wide service definitions that can easily start applications on any member machine. In this guide, we will demonstrate the basic work flow required to create and run a service of your own. We will build a Docker container with our application installed, create systemd-style service unit files, and then use fleet to schedule and start our services.

 

How to Create Flexible Services for a CoreOS Cluster with Fleet Unit Files

Fleet is the cluster-wide service management component of CoreOS. In this guide, we will take an in-depth look at the unit files that define services for CoreOS. We will learn how to create flexible services that take advantage of the power of the CoreOS platform.

 

How To Secure Your CoreOS Cluster with TLS/SSL and Firewall Rules

If you are planning to run a CoreOS cluster in a network environment outside of your control, you may be concerned that etcd communicates over plain HTTP. This guide describes enabling TLS/SSL security and a basic firewall on CoreOS machines.

 

How To Troubleshoot Common Issues with your CoreOS Servers

CoreOS is an extremely powerful operating system focused on cluster management, security, and containerized service deployments. However, the unconventional way that the system is set up can make troubleshooting somewhat difficult. In this guide, we’ll cover the basics of how to track down issues in your deployment as well as your services.
