What is Docker? Docker is a tool to manage containers. What is Container? container is an independent bundle to run applications. Benefit of Docker? Docker saves time and cost for launching and utilizing existing resources for running our applications . Docker Architecture Docker Architecture contains a – client – Docker Server(Deamon) – ContainerD – Kernal Container lifecycle we can create/delete/start/stop/restart/pause/un-pause/kill/remove the containers. How Docker Works!! When a request is made to Docker client ,it runs the image from the registries

What is Docker? Docker is a OS virtualization tool, that allows us to build and deploy applications as containers. Shares resources with underlying OS kernel What is Container? Container is an instance of image that’s having all the tools and libraries that’ll help the software to run. Benefit of Docker? Consistent, cost effective, easy migration between the environments Container Lifecycle: Create–>start–> stop –> start –> restart –> pause –> resume–> kill –> remove where we can create the container, stop

What is Docker? Docker is a tool or platform to simultaneously run multiple applications or multiple instances of same application in a loosely isolated environment. What is Container? It’s a virtual machine which can be configured to run with single mount, NET, PID Map, User in isolated environment. Allocated with separate BOOT FILESYSTEMS + ROOT FILESYSTEMS + USER FILESYSTEMS + APP FILESYSTEMS which enables users to run applications/services independent of other containers while utilizing same resources. Benefit of Docker? Better

What is Docker? It is the tool and platform which helps to manage the containers, developed in Golang. What is Container? It is copy of image or isolated runtime environment for App, which has its own Filesystem, PID, user, network on top of the OS Benefit of Docker? Saves cost, time in spawn/setting up environment Provides the isolated environment with out creating guest OS with help of Docker engine Docker registry has more than 100K images readily available Improves the

Fast to create unlike VMsSince OS is not contained its light weightcontainer also contains the required versions of other applications needed for the appAny number of containers can be created quickly. The portability and performance benefits offered by containers can help you make your development process more agile and responsive

What is Docker? Docker provides a platform for running applications in a containerized approach, where in each container have a file system, pid map and own network. Docker directly interacts with kernel to create mount, pid map, network and a user for each application. Below are the docker components. Docker Engine Docker Engine is responsible for sending commands to kernel to create infrastructure for running an application Docker Image Docker Image contains executable code and instructions like a template. This

What is Docker? Docker is a platform and managing tool which has a containers What is Container?Container is a independent application used in Run time Env which contains 1 mount, 1 user, 1 Network and 1 PID Map Benefits of Docker:Its saves Cost, time and improves the Quality of Application. Docker Architecture:Docker uses a client-server architecture and docker client communicates with the Docker Server(Deamon) which can build docker containers. It is a Restful service where client and Server can communicate

Containers virtualize the operating system unlike VMs, Containers are portable with that it means it can do development and deployment .In terms of docker its also runnable instance of image. we can have all dependency of an software into the image .  containers virtualize the OS, splitting it into virtualized compartments to run container applications.

What is Docker? Its a tool and platform which managing the container. Docker is a software platform that allows you to build, test, and deploy applications quickly. Docker is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers. What is Container? Its Logical entity. It is a running instance of the Docker Image. Docker Image is a template that contains the application, and all the dependencies required to run that application

What is 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. Containers simplify delivery of distributed applications, and have become increasingly popular as organizations shift to cloud-native development and hybrid multi-cloud environments. What is a Container? A container is a standard unit of software that packages up code and all its

What is Docker ? Docker is a tool and a platform to simplify the way we create apps and deploy them. Its based on containerization and since its more light weight, cuts across platforms it is being used all across the industry. It allows :- To create docker images where we store our app content To publish the docker images – host our app content for consumption To run the app as docker container – run application as containers What

What is Docker? Docker is a tool and 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 Container? A Docker container is an open source software development platform. Its main benefit is to package applications in containers,allowing them to be portable to any system running a Linux or

What is Docker? Docker is a Tool/Platform which helps in managing the containers and helps save time, cost and improve the quality of the software. What is Container? Is a fully independent, isolated run time environment for dockers or applications. Benefit of Docker? Saves Time Saves Cost No dependencies Improves the quality of the software Docker Architecture It will have a Docker enginer which is nothing but Docker Client, Restful service and docker server (deamon) and ContainerD to interact with

What is Docker ? Answer : Docker helps in containerization of apps , so that app app gets it own environment to run. What is a container ? Containers virtualize the operating system unlike VMs. Containers are portable with that it means it can do development and deployment . In terms of docker its also runnable instance of image. Benefits of Docker ? Fast to create unlike VMs Since OS is not contained its light weight container also contains the

What is CRUD and its purpose ? The full form meaning of CRUD is “Create” “Retrieve” “Update” and “Delete“. In computer programming, create, read, update, and delete (CRUD) are the four basic operations of persistent storage. CRUD is also sometimes used to describe user interface conventions that facilitate viewing, searching, and changing information using computer-based forms and reports. CRUD operations are basic data manipulation for database. The ability to create, read, update and delete items in a web application is crucial to

What is variable in programming languages? In computer programming, a variable is a storage location (identified by a memory address) paired with an associated symbolic name. It contains some known or unknown quantity of information referred to as a value. Finally A variable is a container for a particular type of data (like integer, float, String etc). example: Java:: int num, String name; Php:: $num (there is not necessary for type) Kotlin:: var num, val num2; What is keys using in

Create a playbook where you should install a webserver into 2 OS type(Ubuntu and RHEL) with fact conditioning. and list out a directory which in “/etc” and display such as “This is a directory /file in /etc:-XXXx” To be used Conditiong, looping, regiter and fact variable.
