We all agree on the fact that...
Automation has become the main component of every development cycle of software. Automation and configuration management look like a stroll in the park, from automating development systems through the setting-up of production settings. In this Ansible interview questions article, we have gathered a list of the most commonly asked questions by professional hiring managers in the field.
But, before we get into these Ansible interview questions, let's explain the word Ansible. Ansible is a software application that provides cross-platform computer assistance through simple yet effective automation. It is primarily aiming towards IT professionals, who use it for application deployment, workstation and server upgrades, cloud provisioning, configuration management, intra-service orchestration, and almost anything else that a systems administrator performs on a weekly or daily basis. Ansible does not rely on agent software and does not require any additional security infrastructure, making it simple to set up.
Since Ansible is becoming increasingly popular, it stands to reason that more firms and organizations are searching for candidates with Ansible experience. This is the reason behind why we have compiled a list of the most frequently requested Ansible interview questions and answers.
Ansible Interview Questions and Answers
Bear in mind that these Ansible interview questions are carefully handpicked by professional hiring managers who have been in the field for years.
Ansible Interview Question N°1: What is CI/CD?
Answer: CI/CD is a technique of delivering apps to consumers on a regular basis by incorporating automation into the phases of app development. Continuous integration, continuous delivery, and continuous deployment are the three major ideas associated with CI/CD. CI/CD is a solution to the issues that new code integration might bring for development and operations teams (AKA "integration hell").
Ansible Interview Question N°2: What is Configuration Management?
Answer: Configuration management refers to the practice of keeping computer systems, servers, and software in a desired, consistent configuration. It is a method of ensuring that a system continues to operate as intended while modifications are in place over time.
Managing IT system configurations include first specifying a system's intended state, such as server configuration, and then creating and maintaining those systems. Configuration management, which is closely connected to configuration assessments and drift analyses, employs both to identify systems that need to stay updated, reconfigured, or patched.
Ansible Interview Question N°3: How Ansible Works?
Answer: Ansible operates by connecting to your nodes and sending tiny programs known as "Ansible modules" to them. These programs aimed to be resource models of the system's ideal state. Ansible then runs these modules (through SSH by default) and removes them after they are completed.
There are no servers, daemons, or databases necessary for your module library to run on any system. To keep track of changes to your material, you'll often use your preferred terminal software, a text editor, and, most likely, a version control system.
Ansible Interview Question N°4: Mention the features of Ansible?
Answer: Ansible has a group of features as follows below:
- Agentless: Unlike puppet or chef, no software or agent is useful to manage the nodes.
- Python: Built on top of python, which is one of the most robust programming languages and is very easy to learn and build scripts in.
- SSH: Passwordless network authentication that is both safe and simple to set up.
- Push architecture: The fundamental idea is to push many tiny codes to client nodes to set up and perform the activity.
- Setup: This is really simple to set up, with a very short learning curve and any open source so that anybody can get their hands dirty.
- Manage Inventory: The addresses of machines are existing within a basic text format, and we can add multiple sources of truth to extract the list using plugins such as Openstack, Rackspace, and so on.
Ansible Interview Question N°5: Briefly explain Infrastructure as Code?
Answer: Infrastructure as Code, or IaC, is a technique that DevOps teams should use to manage infrastructure in a more structured manner. Instead of haphazard scripts or manually setting any cloud component, there should be a code repository where all of these would live, and any changes in configuration should be in place through it. It's also a good idea to place it under source control. This increases efficiency, uniformity, and accountability.
Ansible Interview Question N°6: Explain in detail the Ansible modules?
Answer: Ansible modules are similar to functions or independent scripts in that they perform specific tasks indefinitely. The kind of module determines the return value, which is a JSON string in stdout or input. Ansible playbooks make use of them.
Two types of Ansible modules:
- Core Modules:
Because the core Ansible team is in charge of maintaining these modules, they exist with Ansible. The reported issues have a higher priority than those in the "extras" repo.
- Extras Modules:
Ansible Community mentioned these modules, so they are existing in Ansible for the time being, although they may be phased out in the future. These can be useful, but they will need to stay updated on a low priority basis if there are any feature requests or issues.
The core modules can now include popular extra modules at any time. Separate repositories for these modules are respectively accessible as anamounce-core and anamounce-extra.
Ansible Interview Question N°7: What are ad-hoc commands?
Answer: Ad-hoc commands are a means for us to take action on our hosts without having to write a playbook. For instance, suppose we wish to reset all hosts in a specific group (webservers). Then you can either create a playbook or perform a one-time ad-hoc command.
Ansible Interview Question N°8: Tell me when should you test playbooks and roles?
Answer: Tests in an accessible version to new playbooks or current playbooks. As a result, the majority of testing jobs always provide a clean hosting environment. You will need to make very few if any, code modifications if you use this testing technique.
Ansible Interview Question N°9: What is Ansible Task?
Answer: You may use Ansible Tasks to split down large chunks of configuration policy into smaller files. These are reusable code blocks that may be useful to automate any task. If you want to install a package or update a piece of software, for example, you may use the code snippet below:
Ansible Interview Question N°10: Do you have any questions?
Answer: Most interviewers will ask if you have any questions regarding the position or company at the end of the interview.
If you don't ask any questions, it may seem that you are uninterested in the chance provided. It's usually a good idea to create a list of questions and be ready to talk them out. Here is a list of five questions that you can use:
- What is the overall purpose of the position?
- How do you evaluate the performance of the person in this position?
- What is the typical career path for someone hired into this role?
- What is the history of this position?
- Why is this position that important?
At the end of the day, it's evident that preparing for Ansible interview questions is a challenging task. Yet, the issue that keeps coming up is: how can YOU best prepare for this job interview?
