Creating a module in Terraform - Getting started with Terraform Modules (part 1)

#terraform #devops #infrastructureascode
Once you start seeing patterns in your infrastructure that repeat, e.g. the creation of VPCs, it is time to look at abstracting them into reusable blocks. These are modules in Terraform. This session covers how to create a basic module, looks at defining the inputs (variables) and outputs to it. We then use the module to create our Amazon EC2 instance. The 2nd part of this session will show how to store your module in a git repo, and add versioning.

[ickebinberliner]

Great Tutorial, thank you very much. You helped me a lot!

[zvirtual]

Cobus, thanks for this was as very clear explanation of modules as well as the best example of using the variables.tf file. Nice!

[donskye]

I am enyouying your video. It's very well explain and easy to understand. You make complex explanation to be easy.Ty

[ayencoscolfield]

Could not have asked for more you nailed it man, kudos but could you do a video on the use of different functions in terraform. thanks for the effort so far

[gaspar]

Great content, I learned very about it and I´m studying more about because I have to build an infrastructure with 4 environments and 4 vpc´s. Thank you

[TilakVardhan]

Wow! This is certainly the easiest explanation I've come across.
Thanks, man!

[rodrigueawom]

This was a great experience, Can you pls cover backend.

[ThePotassiumiodide]

Thanks, this was really clear! Do you think you could also share the code through a repo?

[Umarx]

Thanks - could you do one for monitoring and alerting if someone creates/terminates some instance. I want to see some sample TF rules. Thanks!

[stevegrimes]

thanks for the video. I tried to find this example, I'd like to see the root and sub module files.

[michaelduncan]

Thank you for the video. I have a question, what if I wanted to spin up a new instance without destroying the first instance I created. How do I run the same terraform code to create a new instance without destroying the one it created previously and how do I repeat that for future instance creation ?

[wyattblake]

if you needed to create more than one ec2 instance with different settings what would be the best way to do that? Would you create a second module with a different name?

[pallavianand]

Hi Cobus,
This is really simple and understandable. Although I have one question : we have 3 services created in our dev environment : S3, Elastic Search and RDS but I am not understanding that how do I create a module and which would benefit each service? Can you please help me with that.

[amauryborgessouza]

Do you have any GitHub profile to fork the project? appreciate your videos!!!

[saurabhgoreamazing]

Surprised to know that the infra is created without AWS credentials. How are you authenticating terraform

[arvinvitug]

where can you find what can be used as outputs for a given resource?
