Devops Interview questions
First, we must enter your Jenkins system’s e-mail and user name, then navigate to your job directory and run the “git config” command.
Ansible is mostly used to manage or deploy applications to remote nodes in IT architecture. Let’s imagine we want to deploy a single application to hundreds of nodes with only one command. Ansible comes into play here, but you’ll need some knowledge of Ansible script to understand or run it.
Yes, we can!! The only difference between agile methodology and DevOps is that, agile methodology is implemented only for development section and DevOps implements agility on both development as well as operations section.
Sudo (superuser do) is a command-line application for UNIX and Linux systems that allows particular users to run specific system commands at the root (most powerful) level of the system.

A file must be formatted and examined in an intermediate area known as the ‘Staging Area’ or ‘Indexing Area’ before being committed.

Amazon offers the Amazon Elastic Container Service (ECS), which we will use to create and configure task definitions and services before launching the apps.
A DevOps Engineer coordinates with developers, as well as the IT system, in order to manage code releases. They are either developers who have developed an interest in deployment, such as in practise settings, or sysadmins who have converted a passion for scripting and coding into a shift toward the development front, where everyone can improve that test and deployment plans.
Yes, we are capable of doing so. One approach to go about it is as follows:
• By moving the matching jobs folder from one server to another, we can copy Jenkins jobs.
