These are very Basic Ansible Interview Questions and Answers for freshers and experienced both.

Q1: What is Ansible?
A1: Ansible is developed in Python language.

It is a software tool. It is useful while deploying any application using ssh without any downtime. Using this tool one can manage and configure software applications very easily.

Q2: Comapre Ansible VS Puppet
A2:

Q3: What’s the Use of Ansible.
A3: Ansible can be used in IT Infrastructure to manage and deploy software applications to remote nodes. For example, let’s say you need to deploy a single software or multiple software to 100’s of nodes by a single command, here ansible comes into picture, with the help of Ansible you can deploy as many as applications to many nodes with one single command, but you must have a little programming knowledge for understanding the ansible scripts.

We’ve compiled a series on Ansible, title ‘Preparation for the Deployment of your IT Infrastructure with Ansible IT Automation Tool‘, through parts 1-4 and covers the following topics.

Q4: Why are you attracted to science and science fiction?
A4: Early imprinting, maybe, for the science fiction. When I was quite small a family friend let me read his 1950s run of ‘Galaxy’ magazine. My favourite aunt pressed John Wyndham’s ‘The Day of the Triffids’ on me; a more terrifying great-aunt gave me G.K. Chesterton’s fantastic novels; and so on.

The incurable addiction had begun. Meanwhile, science classes just seemed to be the part of school that made most sense, and I fell in love with Pelican pop-maths titles – especially Kasner’s and Newman’s ‘Mathematics and the Imagination’ and all those books of Martin Gardner’s ‘Scientific American’ columns.

Q5: Describe your newsletter Ansible and who it’s aimed at.
A5: It appears monthly and has been called the ‘Private Eye’ of science fiction, but isn’t as cruel and doesn’t (I hope) recycle old jokes quite as relentlessly. Though I feel a certain duty to list some bread-and-butter material like conventions, award winners and deaths in the field, ‘Ansible’ skips the most boring SF news – the long lists of books acquired, books published, book sales figures, major new remainders – in favour of quirkier items and poking fun at SF notables. The most popular departments quote terrible lines from published SF/fantasy and bizarre things said about SF by outsiders (‘As Others See Us’). All the back issues of ‘Ansible’ since it started in 1979 can be read online.

Q6: What is Ansible Tower?
A6: Ansible is classified as a web-based solution which makes Ansible very easy to use. It is considered to be or acts like a hub for all of your automation tasks. The tower is free for usage till 10 nodes.

Q7: What Are The Advantages Of Ansible?
A7:

• Agent-less
• Verylow overhead
• Good performance

Q8: Is There A Web Interface / Rest Api / Etc?
A8: Yes, Ansible, Inc makes a great product that makes Ansible even more powerful and easy to use. See Ansible Tower.

Q9: Desired To Gain Proficiency On Ansible?
A9: Explore the blog post on Ansible training to become a pro in Ansible.

Q10: How Do I See All The Inventory Vars Defined For My Host?
A10: You can see the resulting vars you define in inventory running the following command:

ansible -m debug -a “var=hostvars[‘hostname’]” localhost.

Q11: How Do I Access A Variable Name Programmatically?
A11: An example may come up where we need to get the ipv4 address of an arbitrary interface, where the interface to be used may be supplied via a role parameter or other input. Variable names can be built by adding strings together, like so:

{{ hostvars[inventory_hostname][‘ansible_’ + which_interface][‘ipv4’][‘address’] }}

The trick about going through hostvars is necessary because it’s a dictionary of the entire namespace of variables. ‘inventory_hostname’ is a magic variable that indicates the current host you are looping over in the host loop.

Q12: How do I access a variable of the first host in a group?
A12: What happens if we want the ip address of the first webserver in the webservers group? Well, we can do that too. Note that if we are using dynamic inventory, which host is the ‘first’ may not be consistent, so you wouldn’t want to do this unless your inventory is static and predictable. (If you are using Ansible Tower, it will use database order, so this isn’t a problem even if you are using cloud based inventory scripts).

Anyway, here’s the trick:

{{ hostvars[groups[‘webservers’][0]][‘ansible_eth0’][‘ipv4’][‘address’] }}

Notice how we’re pulling out the hostname of the first machine of the webservers group. If you are doing this in a template, you could use the Jinja2 ‘#set’ directive to simplify this, or in a playbook, you could also use set_fact:

– set_fact: headnode={{ groups[[‘webservers’][0]] }}

– debug: msg={{ hostvars[headnode].ansible_eth0.ipv4.address }}

Notice how we interchanged the bracket syntax for dots – that can be done anywhere.

Q13: How do I copy files recursively onto a target host?
A13: The “copy” module has a recursive parameter. However, take a look at the “synchronize” module if you want to do something more efficient for a large number of files. The “synchronize” module wraps rsync. See the module index for info on both of these modules.

Q14: Is there a web interface / REST API / etc?
A14: Yes! Ansible, Inc makes a great product that makes Ansible even more powerful and easy to use.

Q15: Why don’t you ship in X format?
A15: Several reasons, in most cases it has to do with maintainability, there are tons of ways to ship software and it is a herculean task to try to support them all. In other cases there are technical issues, for example, for python wheels, our dependencies are not present so there is little to no gain.

Q16: How do I submit a change to the documentation?
A16: Documentation for Ansible is kept in the main project git repository, and complete instructions for contributing can be found in the docs.

Q17: What is the best way to make content reusable/redistributable?
A17: If you have not done so already, read all about “Roles” in the playbooks documentation. This helps you make playbook content self-contained and works well with things like git sub modules for sharing content with others.

If some of these plugin types look strange to you, see the API documentation for more details about ways Ansible can be extended.

Q18: How can you speed up management inside in EC2?
A18: It is not advised to manage a group of EC2 machines from your laptop.

The best way is to connect to a management node inside Ec2 first and then execute Ansible from there.

Q19: How can you access a list of Ansible_Variables?
A19: By default, Ansible gathers facts under machines under management. Further, these facts are accessed in Playbooks and in templates. One of the best ways to view a list of all the facts that are available in a machine, then you need to run the setup module in the ad-hoc way:

Ansible- m setup hostname

Once this statement is executed, it will print out a dictionary of all the facts that are available for that particular host. This is the best way to access the list of Ansible_variables.

Q20: Is Ansible is an open source tool?
A20: Yes, Ansible is an open source tool which is a powerful automation software tool that one can use.

Q21: Can you build your own modules with Ansible?
A21: Yes, we can create or own modules within Ansible.

It is an open source tool which primarily works on Python. If you are good at programming in Python you can start creating your own modules in few hours from scratch and you don’t need to have any prior knowledge of the same.

Q22: Explain Callback_plugin in Ansible?
A22: Callbacks are explained as a piece of code in ansible environments where get is used call a specific event and permit the notifications.

This is more sort of a developer related feature and allows low-level extensions around ansible so that they can be loaded from different locations without any problem.

Q23: Explain in detail about ad-hoc command?
A23: Well, ad-hoc commands is nothing but a command which is used to do something quickly and it is more sort of a one-time use. Unlike, the playbook is used for a repeated actions which is something that is very useful in Ansible environment. But there might be scenarios where we want to use ad-hoc commands which can simply do the required activity and it is a nonrepetitive activity.

Q24: When Should I Use {{ }}? Also, How To Interpolate Variables Or Dynamic Variable Names?
A24: One of the standard rules is ‘always use {{}} except when:’. Conditionals are always run through Jinja2 as to resolve the expression. So when:failed_when: and changed_when: are always templated and we should avoid adding {{}}.

In other cases except when clause we have to use brackets, otherwise distinguish between an undefined variable and String will be very difficult.
