Terraform is OpenSource infrastructure as a code software tool. With the help of Terraform you can provision infrastructure on cloud platform such AWS(aws.amazon.com/), Google Cloud(cloud.google.com/), Azure(azure.microsoft.com/en-us/), DigitalOcean(www.digitalocean.com/), OpenShift(www.openshift.com/) and many more...cloud provider
But before you start working with Terraform you must understand different types of variables provided by the terraform -
1. variable.tf - This file is used for declaring and defining variables
2. terraform.tfvars - It is also used for declaring and defining variables but can be used for multiple environment like staging, production
3. commandline vars - If you want to pass the variable using terraform commandline

Hey hello Rahul I have doubt I have one file called (variable.tfvars) if I change this name into (vars.tfvars) the actual values of (variable.tfvars) not coming so what is the difference between (variable.tfvars to vars. tfvars) can you explain

[@vivekpuurkayastha1580]

when using .tfvars file, should the variables in the variable.tf file be totally empty or can it contain description and type but just not the default value?

[@MaheshGaikwad21]

I have on query regarding .tfvars file. if we have different env like dev staggin prod how we managed this tfvars file and where we stored this file?

[@kumargaurav4246]

i was expecting that when i run 2 plans with the tfvars files i would end up with 2 resources, however i end up with 1 resource that terraform want’s to replace…any help would be greatly appreciated!

[@prafulldeshmukh5940]

Hey Rahul, which terminal you have used run the command like terraform init, etc? Is it gitbash or cmd?

[@aniketkhadye6814]

Great video So helpful for fresher Pls cover full terraform topic

[@RahulWagh]

There are more to come on terraform in upcoming weeks. Making video more detailed and concise take a little time. But stay tuned I will be covering the complete the terraform topics . //Rahul

[@pawankumar786]

@@RahulWagh no where in web we have terraform with Google cloud in detail. Will follow your tutorial .. looking forward for more in-depth material on terraform and Google cloud

[@RahulWagh]

Hey Pawan, Well I am having one lab session on my channel where i explained about Google Cloud and Terraform, I would recommend you to follow that lab session. Here is the time stamp of that particular part where I have shown how to get started with Terraform on Google Cloud - kzbin.info/www/bejne/oHu7Z4Zrf6Z6pqs Click on the above link that. I am planning to upload similar lab session in upcoming weeks and months, so if you have any topic then please post here I will add it into my list //Rahul

[@Kosantosh]

Thanks for your effort to explain things simply, concept is clear, I have a query, do .tfvars file should have variables defined in variable.tf file?

[@RahulWagh]

Yes, correct

[@raveendravajrala2919]

Thank you for your efforts and sharing , Can you help me what is the destroy command when we are using multiple .tfvars file for the same mail.tf , will it be >terraform destroy --var-file ="stage.tfvars" ?

[@rajivnayanverma6822]

yes

[@sanketgangurde9445]

sir can you please tell that how does terraform file calls terraform variable file

Cheeers

[@assrpavanteja7392]

Hi Rahul , is there a way where I'll plan the code and want to issue terraform apply at some point around 11 pm in the day ? is that possible using terraform?

[@RahulWagh]

You can create a bash script and in that script you write down all of your terraform command and save them some where. After that you need to write chron job to execute that bash script at whatever time you need

[@ashishdeokar580]

Hello Rahul, Videos are crisped and well explained.. I do have query here.. Thank you so much for sharing a knowledge. Is it necessary to execute terraform plan 2 times for stage.tfvars & production.tfvars ? Can't we make add 2 tfvars in single command ?

[@RahulWagh]

No it is not necessary to run terraform plan two times, one time is more then sufficient

[@devopsprabhakar806]

Suppose we execute firat stage.tfvar and after prod.tfvar then will it overwrite the state file? Or it will update entry in state file for stage and prod both?

[@silentwatcher13]

It overrides the current state.. i want to know how we can achieve this (same state file for both tfvars) 👆🏼?..

[@RahulWagh]

If you are planning to execute the same terraform file in different environment then I would recommend using terraform workspaces because if you use stage.tfvar and then prod.tfvar it will lead to very unstable tfstate. terraform workspaces is meant to solve such problem where you can run the same infra with different profiles

[@ksundar369gmail]

How to pass variables with tfvars, while trying to call modules?

[@narenderkondisetty9704]

Excellent Job Rahul......Have a small doubt.....if i have two .tf files in one folder and when i say terraform plan and terraform apply,which .tf it will consider.

[@RahulWagh]

I guess it will consider both .tf files

[@saeid5914]

Thank you Rahul for your great session, I couldn't run variables .tfvars codes for gcp, so far rest of variables successfully ran, can you/anyone advise please?
