Top 8 Recommended Packer Self-Study Materials! [November 2024]

Master HashiCorp Packer to automate your machine images across multiple platforms - a critical skill to enabling automation in your environments.

This is the most extensive and thorough course on Udemy for learning how to use HashiCorp Packer in your organization. It is the only course that teaches you all about using HCL2 to create your Packer templates, the new standard moving forward. It doesn't matter if you have never used Packer before or have been writing Packer templates in the older JSON style. You'll step away from this course ready to tackle any Packer build.

This course includes in-depth lectures on all of the core HashiCorp Packer components and tons of included labs. You also get access to hands-on labs that you can perform in your own environment, as we believe taking a hands-on approach is the best way to learn. Each lesson includes a mindmap of the topics, a PDF of the slides, and multiple labs to demonstrate the topics at hand.

Beyond getting comfortable with HashiCorp Packer, we're taking it one step further and showing you how to integrate HashiCorp Packer with other automation tools, such as HashiCorp Terraform, HashiCorp Vault, and GitLab CI/CD. We'll demonstrate building images on multiple public cloud platforms, and we'll even show you how to build VMware images using Packer.

We cover a wide variety of topics, including:

• HashiCorp Packer intro and the problems it solves

• Use Cases and Examples

• Writing Packer Templates using HCL2 (the new standard for Packer 1.7+)

• Different Builders

• Using Variables

• Provisioners

• Post-Processors

• Code Organization

• Integrations such as automation pipelines, secrets management, Terraform, and more.

You will get lifetime access to a wealth of content plus all of the labs for your own use. Don't forget that this course also comes with Udemy's 30-day guarantee.

In this course, you'll learn how to turn existing server configuration scripts into a Packer build project which creates a fully-configured machine image that you can use on Amazon's cloud. It's a simple, real-life project that shows you how Packer is REALLY used in the Cloud Infrastructure and DevOps world.

By the time you're done, you'll have automated an image build for a server that hosts a WordPress site.

You will learn:

1. How to install Packer

2. How to create and structure a simple Packer template to build an a machine image on AWS

3. How to think about turning existing commands/procedures into scripts, and how to use those scripts in your Packer workflow.

4. How to create VMs (AWS Instances) from the machine image you created with Packer.

Who Are You?

• You're a Linux, DevOps, Cloud Infrastructure, or Software Engineer who wants to automate server image builds.

• You have some basic command-line skills (Linux, Windows, or OS X).

• You know how to clone a project from GitHub and edit code in a text editor.

• You want to learn more practical DevOps skills.

• You want to automate image builds as a first step to making Infrastructure configuration part of a CI/CD pipeline.

• You're just curious about what a small, but real-world Packer project looks like.

Who am I?

• I've been doing Linux, Cloud Infrastructure, Software Development, and DevOps/SRE for almost 15 years.

• I've taught hundreds of thousands of people tech skills on my YouTube channel.

• I want to teach important skills in a useful, no-BS way that gives you practical skills that you can immediately apply to real-world projects, in job interviews, or to get promoted.

Take a look! I'm excited to see you inside.

Deployment is usually one of the aspects that is tackled last when it comes to application development, and until only recently deployment experience for both Developers and Operations teams was very painful.

To this end, DevOps practices have now been adopted quite widely, and in a nutshell, DevOps is the intersection between Development and Operations.

A lot of tools have been created to tackle the pain points of making a deployment and these fall into different categories, like configuration tools, server templating, and Infrastructure as Code to mention a few.

Now in a lot of tutorials and courses, the focus is on learning and using these tools individually without any real world context. This means that you will need to use these different tools together yourself, and this can be difficult to use them in a real world context.

In this course we will be making a hands on deployment of an E-commerce Node API application with a custom SSL domain using a combination of the deployments tools that are available. These include:

• Git Version control

• Linux

• Bash Scripts

• Terraform

• Docker

• Packer

• Continuous Integration - GitHub Actions

• AWS

We're going to use all of these tools together to make an automated deployment without any manual steps such as configuring infrastructure resources in the UI console. We're also going to have the advantage of versioning our infrastructure in Git, which means that should there be any issues we can simply roll back the infrastructure deployed to a previous state very easily.

LEARN A PRODUCTION GRADE PROJECT

This is a unique course designed to help you to create a customized Azure DevOps agents from the ground up. Currently, most software teams that are using Azure DevOps to build their software choose to use Azure-hosted agents as their build server. This comes with a lot of benefits. Many libraries are already installed on these agents so it's quite compatible with most projects' specifications. For every build, you get a new agent that is provisioned and after the build will be destroyed. However, this has its own limitations. Azure Hosted Agents are using a specific type of VM so it is not possible to increase hardware specifications. If your projects also have libraries that are not supported by Azure Hosted agents, you need to install them on the agents. This might not be an issue for projects that have started in recent years, but if you have a legacy code that takes an hour to build then you might start to think about how you can speed up the build process. For such a situation, there are a lot of solutions like reconsidering the architecture of software and so on which is not the scope of this article. In this article, I am going to focus on how you can create a custom self-hosted agent.

CUSTOM SELF HOSTED AGENT

With Azure DevOps, it is possible to create an agent pool and add our own agents. These agents can be your personal laptop, on-premise server, or virtual machine. What we want to do in this course is to see how we can create a fully automated process in which we create a custom Windows image. This gives us the benefit of having an image containing all the applications and settings we need. Additionally, we can provision a virtual machine/virtual machine scale set using this image with desired hardware specifications.

UNDERSTAND THE DESIGN, THEN LEARN HOW TO IMPLEMENT

What makes this course unique is that you understand the design process before you jump into the implementation. It is important to know why we choose certain ways and then learn how to implement it. I walk you through all required steps and you get along with me to implement this solution while watching me coding.

EVERYTHINGS AS CODE

These days it is quite important to have everything as code. It is the same for pipelines. In this course, I am using PowerShell scripts, Packer, Azure DevOps YAML pipelines and Azure ARM templates. So you learn how to use all these tools in a project and I explain everything in detail.

USEFUL FOR VARIOUS PROJECTS

This course if very useful for different purposes. It can help you to learn:

• How to create a customized Windows Image using Packer

• How to create a Virtual Machine Set using customized image

• How to use Azure Keyvault for secrets in the Azure DevOps YAML pipelines

And so many other things you would need to know when you implement projects like these.

YOU HAVE MY FULL SUPPORT

During the course, I am always available to help you with your questions and perhaps problems you are facing. The aim of this course is to equip you with enough knowledge to understand the CI/CD concept and additionally get familiar with Azure DevOps tools. With these, you are able to start creating your pipelines in different scenarios and bring added value to your projects and your companies.
