What is Docker tutorial?This tutorial explains the various aspects of the Docker Container service. Starting with the basics of Docker which focuses on the installation and configuration of Docker, it gradually moves on to advanced topics such as Networking and Registries.
Article first time published onIs Docker a virtual machine?
Docker is container based technology and containers are just user space of the operating system. … In Docker, the containers running share the host OS kernel. A Virtual Machine, on the other hand, is not based on container technology. They are made up of user space plus kernel space of an operating system.
What is difference between Docker and Kubernetes?
A fundamental difference between Kubernetes and Docker is that Kubernetes is meant to run across a cluster while Docker runs on a single node. Kubernetes is more extensive than Docker Swarm and is meant to coordinate clusters of nodes at scale in production in an efficient manner.
Can Kubernetes manage Docker containers?
Kubernetes is open-source orchestration software that provides an API to control how and where those containers will run. It allows you to run your Docker containers and workloads and helps you to tackle some of the operating complexities when moving to scale multiple containers, deployed across multiple servers.
Is GitHub configuration management?
GitHub is well suited for groups of developers working on a single code base. GitHub is also well suited for configuration management if used in conjunction with Ansible or Puppet. By checking in changes to configuration management code like YAML you are able to quickly review and audit changes.
What is configuration management example?
A telecom firm maintains a configuration management database that includes relationships between components. … For example, if a router goes down the firm has immediate access to a list of impacted services and customers. The company phones customers to tell them their service is down before they typically notice.
What is configuration management in ITIL?

ITIL defines Service Asset and Configuration Management (SACM) as: “The process responsible for ensuring that the assets required to deliver services are properly controlled, and that accurate and reliable information about those assets is available when and where it is needed.
Is Puppet similar to Kubernetes?
Kubernetes is an open source orchestration system for Docker containers. … Puppet is an automated administrative engine for your Linux, Unix, and Windows systems and performs administrative tasks (such as adding users, installing packages, and updating server configurations) based on a centralized specification.
What is the difference between Puppet and Docker?
Puppet oversees files, packages, and services, while Docker configures documents inside a delivery unit called a container. … Puppet includes many tools that will allow you to easily configure a system, whereas Docker is used to build and deploy applications.
What is the difference between Ansible and Puppet?
The difference is that ansible-playbook can be run from centralised places, whereas Puppet needs an agent to run on each node. … In short, Puppet will always require an extra component/package to be installed on the destination server to make it all work, regardless if you go masterless or not.

What is docker swarm manager?
Docker swarm is a container orchestration tool, meaning that it allows the user to manage multiple containers deployed across multiple host machines. One of the key benefits associated with the operation of a docker swarm is the high level of availability offered for applications.
How many managers are there in docker Swarm?
Docker recommends a maximum of seven manager nodes for a swarm. Important Note: Adding more managers does NOT mean increased scalability or higher performance.
What is the purpose of Docker?
Docker is an open source containerization platform. It enables developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment.
Where is Docker used?
Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications.
What is docker in simple terms?
Docker is an application build and deployment tool. It is based on the idea of that you can package your code with dependencies into a deployable unit called a container. … For a visual explanation, think of the shipping containers used for intermodal shipping.
Is Docker difficult to learn?
It’s really, really not hard to learn, though. At least if you understand the command line. I’d do one better, you should learn about containerization in general. Docker is only one very specific implementation of Linux c groups functionality and it makes a lot of assumptions for you.
