CoreOS Training in Pune

CoreOS Training in Pune

CoreOS is a barebones Linux distribution designed to make large multiple-machine deployments, using different softwares and dependencies, easier to scale and easier to manage. It is built for high availability and security. It does not come with a package manager and thus requires containers such as those provided by Docker. It uses “fleet” for cluster management and “etcd” for service discovery and keeping configuration up to date across the cluster.

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.
