Excellent course and Thanks so much for it!

I tried following the instructions but got stuck

The directory has no Terraform configuration files. You may begin working

with Terraform immediately by creating Terraform configuration files.

How to tell via terraform that I need redhat ec2 AMI image

Excellent Video. I am a Data engineering guy and I wanted to learn this TF. No words Excellent.

Can I use this course in 2024 to learn Terraform?

Can you please create one more video where we do have separate .tf file for group of resources and also how are we resolving to secrets on prod ?

Does anyone know what to do after this video?

so much better, one place to cover all basics

have anyone let me know, this course are still worth nowaday tho?

This is a solid beginner for anyone interested in learning Terraform.

Great tutorial – thank you! Just a question on the declarative language. At @45:00 you mentioned that we will always have one aws resource in the console because that is what is written in your code. So why does the console show two ec2 instances then? i.e. if the terraform code only has one ec2 instance, shouldn't terraform build it the same in the console too (by deleting the pre-existing ec2 and making a new one as per the main.tf file? – at this point there are two ec2 instances in the console while there is only one ec2 in the main.tf file)

very helpful

Thankyou for clearing my basics, I think I wouldn't need to dive deeper into tutorial hell

The best course for beginners. I highly recommend everyone to start from here.

you wrote the wrong port…2 instead of 22

Loved your video, I learned so much in this 2 hour tutorial. I'm now confident working with Terraform and hope to land a job in Cloud soon.

For those having problems with server saying CONNECTION REFUSED it is most likely that the user data is not running. You can instead create a .sh file in the same folder of the Terraform project and add the commands there omitting the EOF, just add the lines with sudo. We then access the .sh file doing the following in the user_data section:
user_data = file("${path.module}/filename.sh")

That should work

Also I just discovered we can Output more than one value by using a list:

output "name" {
value = [resource.propert1, resource.property2….]
}
