HashiCorp Packer Tutorial: Building Custom Images for AWS, Azure, and Docker

In this video, we'll be diving into HashiCorp Packer, a powerful tool for creating machine images for multiple platforms in a repeatable and automated way. You'll learn how to get started with Packer, including installation and setup, building images for different platforms, and using Packer with other HashiCorp tools. We'll also cover best practices and tips for using Packer effectively.

Those new to the Programming and DevOps world often find it challenging to start their journey due to the missing basic prerequisites. For example, issues with setting up a basic lab environment using VirtualBox, problems with networking, or trouble with working with the Linux CLI or text editors like vi editor. Sometimes there are issues with applications - like getting a sample application to work, problems with getting the dependencies to install correctly or trouble with getting a web server to communicate with a database server. Or, at other times, it's working with data formats like JSON or YAML.
So we have identified a gap, and we believe that this is due to missing some of the basic prerequisites, such as knowing the basics of Linux, the basics of tools like VirtualBox, or knowing the basics of the most commonly used applications like Java, Python or NodeJS or web servers like Apache, NGINX etc. As a DevOps or Cloud Engineer, it is crucial to have these basics cleared. And that’s why we are helping you to bridge that gap!

[@enemarius]

But the new instance name will be the same as the template? I mean the internal os hostname not the cloud vm name.

[@zaheerkhan8726]

Thanks for the video. Can you also make a video on windows image using ssh communicator to upload files and folders in to the image with file provisioner. I tried it by using winrm but that is damn slow. Tried with ssh communicator but that doesn't work for windows.

[@adithyashetty004]

We can build custom AMI from an instance through the AWS console, so why use Packer to build images?

[@KodeKloud]

There are a lot of advantages, you can read it here: developer.hashicorp.com/packer/docs/intro/why

[@bernardesk2]

versioned infrastructure with all changes to the infrastructure mapped, solving the problem of snowflake servers in which no one knows what changed in it, thus making trobleshotting difficult

[@user-qr1hc9wq4b]

Hi. Can you help me please? At stage " Waiting for SSH to became available..." i have an error: Error waiting for SSH: Packer experienced an authentication error when trying to connect via SSH. This can happen if your username/password are wrong. You may want to double-check your credentials as part of your debugging process. original error: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

[@KodeKloud]

Hey, give it a try by following this link: stackoverflow.com/questions/70454523/error-waiting-for-ssh-packer-experienced-an-authentication-error-when-trying-to

[@sksafikuddinkhan5935]

How provisioner connect to instance

[@KodeKloud]

When you configure your Packer template (usually in JSON or HCL format), you specify the SSH key pair that Packer should use to connect to the EC2 instance. The key pair consists of a public key, which is installed on the EC2 instance, and a corresponding private key, which Packer uses to authenticate and establish a secure connection.

[@evrydaylearner]

What is the point of using Packer to create Docker images? Docker can do that seamlessly.

[@KodeKloud]

Thanks for watching our video and sharing your thoughts. Do subscribe to our channel and stay tuned for more. Cheers!

[@sksafikuddinkhan5935]

How ssh connection happens and ansible connect

[@KodeKloud]

Once the instance is running, Packer connects to it through SSH (or other communication methods, depending on the provisioner) and runs the defined provisioner scripts or commands.

[@akashan6811]

Packer is an alternative to Docker??

[@shahzadansari9728]

Nope , packer is usd to build golden images for VMS

[@KodeKloud]

No, Packer is an automated build system to manage the creation of images for containers and virtual machines. It outputs an image that you can then take and run on the platform you require.

[@NajeebKhan-he1pw]

Need packer full fledged course on kodekloud

[@farzadmf]

So, what's the difference between Packer and Terraform? When should we use which?

[@VirtualizeStuff]

Hello, You use Packer create your custom AMI then utilize Terraform to deploy an EC2 instance with that custom AMI.

[@farzadmf]

Nice, thank you for your answer
