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!

What is the post-procrssor in azure/aws to push the Image to blob/s3 storage?
But the new instance name will be the same as the template? I mean the internal os hostname not the cloud vm name.
We can build custom AMI from an instance through the AWS console, so why use Packer to build images?

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.

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

How provisioner connect to instance
@KodeKloud
Жыл бұрын
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.
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.
What is the point of using Packer to create Docker images? Docker can do that seamlessly.

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.
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.
