Introduction – 

Think of a system administrator managing numerous servers. They can quickly resolve any problems that may arise with one of the servers. However, when several servers are down, the situation becomes severe. Puppets can be useful in this situation. You can create straightforward code with Puppet and deploy it to the problematic servers. All servers are instantly reset to their original desired states or rolled back to their former operational states after the code has finished running.

Puppet may be used to deploy software and add security using only a few lines of code. Following are the subjects covered in this puppet article:

What is a Puppet?

Puppet is a configuration management solution that makes sure all systems are configured to a desirable and predictable state. You may also use it as a deployment tool because it has the ability to automatically install apps on the system. You may test the environment and ensure that the infrastructure is installed properly because Pup-pet implements infrastructure as code. After defining what Pup-pet is, let’s examine its components.

Components of Puppet – 

The primary server environment (seen above) and the client environment can be separated out of the Puppet environment. A Pup-pet master store, which houses all configuration files, is present in the main server environment.

• The actual codes for configuring the clients are manifests.
• Code and data are combined in templates to produce the final document.
• Files are the static content that clients can download.
• Manifests, templates, and files make up modules.
• The master may sign the certificates that the client sends, thanks to the certificate authority.

The computer that needs to be configured is the Pup-pet client, which consists of Agent and Facter. To make sure that the certificates are updated properly, the agent communicates with the master server continuously. When a client is used, the factor gathers its current status and passes it to the agent. After looking at the parts of a pup-pet, let’s study how a pup-pet functions in order to better understand what a puppet is.

How Puppets Work?

The architecture of Pup-pet uses major and secondary nodes. In order to communicate with the primary-secondary environment, which contains Pup-pet modules, the clients are dispersed across the network. The server receives a certificate from the client agent along with its ID, signs it, and sends it back to the client. Between the client and the master, this authentication enables secure and verified communication.

The factor then gathers and transmits to the master the customers’ state data. The master puts the manifests together into the catalogues based on the fact supplied, and an agent puts the manifests into action on its computer. The catalogues are transmitted to the clients. The client produces and sends to the master a report outlining any changes made. To make sure all client systems are current, this procedure is conducted on a regular basis. As part of our understanding of what Pup-pet is, let’s learn more about the numerous businesses that are utilizing it in the following section.

Why use Puppet?

International corporations are intricate and decentralised. Any group of system administrators responsible for an organisation’s IT infrastructure (data centres, server centres, and connected systems) will eventually reach critical mass. This occurs when the IT needs of the firm outweigh the team’s capabilities. This puts IT leaders in a bind without making adjustments to the budget and staffing levels.

Puppet steps in at this point, allowing smaller teams to utilize sophisticated automation to complete more jobs. Updates to data centers and servers can happen instantly. Due to Puppet’s ability to immediately roll back to previously operational states, the effects of server failures are reduced. With on-demand server installations and strict security, Puppet reduces deployment headaches. Simple Ruby scripts are used to activate everything.

Benefits of Puppet –

Here are some advantages of puppet for your consideration.

• Infrastructure as code (IAC) definition: Puppet makes it simple to define your infrastructure as code (IAC) by just creating a few puppet scripts. IAC plays a key role in DevOps procedures including version control, peer review, automated testing and deployment, and continuous delivery.
• Due to the relatively quick recovery period, any downtime caused by configuration errors is minimized and frequently eliminated.
• Due to its rapid deployment, Pup-pet offers significant time savings.
• A more comprehensive open source developer environment supports Pup-pet.
• Unlike scripting, pup-pet makes it simple to automate repeated activities, so it can operate flawlessly even on a massive infrastructure.
• It works with many different operating systems, including Microsoft Windows, Debian, BSD, etc.
• The configurations for a host are defined by Pup-pet using an accessible language.

Application of Puppet – 

Let’s use a case study to learn about Puppet’s applications. You must be familiar with Zynga if you enjoy playing poker or have ever participated in online gaming. It is the biggest maker of social games in the world. Tens of thousands of servers in both private data centers and public clouds are used by Zynga’s infrastructure. To bring hundreds of servers online in the beginning, they used a manual method that included kick starters and post installations.

We shall now examine the challenges they encountered during this procedure:

Scalability & Consistency – Zynga was expanding at an incredible rate, therefore its infrastructure needed to stay up with the business. They needed more than script-based approaches and manual methods could provide.

Portable Infrastructure – For both their private data centres and their public cloud architecture, Zynga needed a solution to use a common configuration management approach.

Flexibility – It was crucial for the team to be able to quickly match the ideal configuration for the ideal machine given the diversity of the numerous Zynga gaming sites.

Infrastructure Insights – Having a system in place to automatically see each machine’s characteristics grew more crucial as the organisation matured.

Even before they saw rapid expansion, the business was astute enough to recognise the need for an automated procedure, which is when Puppet entered the picture. Let’s examine the role Puppet plays in their organisation.

Speed of Recovery – The right configuration may be quickly deployed to the appropriate box by the production operations team. If a system is incorrectly misconfigured, Puppet will either automatically roll it back to its previous stable configuration or provide you the information you need to quickly fix it yourself.

Speed of Deployment – Puppet has allowed the operations team to supply services to the gaming studios with a significant time savings.

Consistency of Servers – The model-driven architecture of Pup-pet guarantees reliable deployments. There is no denying that we have saved time, according to Mark Stockford, Vice President of Production Operations at Zynga. The advantage of utilising Puppet is that we can quickly and reliably deliver uniform configurations across all of our servers.

Collaboration – A model-driven approach makes it simple to exchange configurations across the organisation, allowing operations and development teams to collaborate to guarantee the delivery of new services is of the highest calibre possible. The Zynga staff received training on puppetry from more than a dozen people. This information has been shared with the entire team as well as the operations teams inside each specific game studio.

How to Install Puppet Automation Tool?

• Select the various deployment models, such as the client-server approach, first. As a client-server approach, Pup-pet uses the master and agents.
• Next, choose the puppet master’s server. Before installing the agents, the pup-pet master needs to be set up on the server. Installing the puppet master can be done on any Unix or Linux server. The Windows computer will not function.
• The puppet must be able to manage a lot of intense traffic, so check the system requirements and OS versions third.
• The port 8140, for example, needs to be unoccupied and available for the puppet in order for the firewall to allow for master-agent communication. The hostname of each node must be distinct. It is necessary to configure the forward and reverse DNS properly.
• The NTP module must be used to connect to the NTP server in order to set the puppet master’s time, which is the fifth step.
• The nodes that the puppet master connects to must then have the agents installed.

How is Puppet Trending?

A large number of developer contributions The source code of this programme is constantly being updated by numerous people.

Huge user base – Even institutions like Harvard and Stanford use this application, which is used by over 30,000 businesses. This tool is used by about 20 new organisations every day.

Good commercial usage – Pup-pet has been in use for business purposes since 2005 and is occasionally enhanced. With more than 5000 devices, it has been effectively used in businesses with very large infrastructures.

Documentation – There are hundreds of pages of documentation, both for the language category and the resource category. Various forums frequently discuss it. So, if someone is having problems with the Puppet tool, finding a solution is simple.

Platform support – Any platform that supports Ruby-like software, such as Microsoft Windows Server, Oracle Enterprise Linux, etc., can operate the Puppet server. Pup-pet can also be used with many deployment strategies, including private, public, and hybrid clouds.

Conclusion – 

You should be aware that Puppet is used by 2/3 of Fortune 100 businesses. Regardless of where your software is running, Pup-pet is an excellent tool for inspecting, delivering, and managing it. It is possible to safeguard the infrastructure while simultaneously enforcing consistency across the board. Due to the benefits of Puppet, it can be updated as needed and the systems will still be in compliance with the new updates. One can use a simple language to create their apps and infrastructure. One need only update their data centre and cloud platforms to reflect those changes.
