That’s why asking the right DevOps interview questions is essential, to ensure you find the right person for the role. In continuous testing, the process of executing the automated test is part of the software delivery process.

This DevOps interview question will help you uncover what your candidate might struggle with already or what they might not have a ton of experience with. Now you can tell where it is present and how it is created. A sample main configuration file is created in the base directory of the Nagios distribution when you run the configure script. The default name of the main configuration how to become a devops engineer file is nagios.cfg. It is usually placed in the etc/ subdirectory of you Nagios installation (i.e. /usr/local/nagios/etc/). For this answer, first point out the basic difference Active and Passive checks. The major difference between Active and Passive checks is that Active checks are initiated and performed by Nagios, while passive checks are performed by external applications.

Explain the difference between git fetch and git pull.

I will advise you to begin this answer by giving a small definition of Continuous Integration . It is a development practice that requires developers to integrate code into a shared repository several times a day.

  • The idea is to help get products out faster and allow for easier maintenance.
  • Companies hiring DevOps engineers intend to improve the pace of development and facilitate problem-solving and innovation in the production environment, and enhance the reliability of applications.
  • It assists with the administration and management of various servers and preserves the sincerity of the entire infrastructure.
  • In your interview, you must be able to demonstrate how to develop such a system.
  • DevOps is a workplace culture that brings IT Ops and development together to remove roadblocks to faster product delivery.

This has a unique feature that ensures the development environment is properly and then published in a service that integrates it with the remaining applications. Software programs known as configuration management systems enable the consistent, dependable, and secure control of an environment. While CI automates the build, continuous deployment and continuous delivery automate releases. Create a Docker-based program that builds a fresh, isolated production mirror with each deployment. On the clone/mirror, integration tests can be performed without the risk of damaging crucial infrastructure. Each integration is checked using an automated build process, which enables teams to identify issues with their code even before it is released. More than 8 in 10 informational technology leaders say they use DevOps practices in the workplace, according to Puppet.

How do you stay organized? Describe tools and techniques.

With theaverage cost of a data breachprojected to hit $150 million this year, companies can ill afford to let security to take a backseat during their automation efforts. If you’re not a fresher, you must also go through a few intermediate-level DevOps interview questions to prepare yourself for the interview.

Its continuous delivery practices have also resulted in more than 50 deployments per day with very few disruptions. DevOps provide many technical benefits like continuous software delivery, less complex problems, and faster resolution.

What is Automation Testing?

The file system for the container persists even after the container halts. Explain how you have scripted Docker and used Docker with other tools like Puppet, Chef or Jenkins. If you have no past practical experience in Docker and have past experience with other tools in similar space, be honest and explain the same.

Puppet is a Ruby-based Configuration Management tool, but while it has some free features, much of what makes Puppet great is only available in the paid version. Organizations that don’t need a lot of extras will find Puppet useful, but those needing more customization will probably need to upgrade to the paid version. Verify command also checks whether the given condition is true or false.

This allows for more scalable infrastructure configuration and more importantly allows for transparent tracking of changes through usually versioning system. The first step in the pipeline starts the build process of the application. If the migrations are successful, they will trigger the deployment pipeline if not the application won’t be deployed.

  • The last one lists out all the branches available and also highlights the branch we are in currently.
  • Planning and software development is the first phase of the DevOps lifecycle.
  • Once the develop branch has acquired enough features for a release, you can clone that branch to form a Release branch.
  • If you’re more experienced, you should also prepare for advanced-level DevOps interview questions.
  • There is a single source of truth for the pipeline, which can be viewed and edited.
