Terraform Data Sources | How to Use Data Sources? - Part 12

▬▬▬▬▬▬ ⭐️ Instruction guide ⭐️ ▬▬▬▬▬▬

Terraform data sources can be used to fetch information back from the Cloud service provider (AWS, Google Cloud, Azure etc..). Along with your terraform provisioning script you need to write the terraform data source resource block for creating the data sources.

Terraform data sources can help you to fetch -

1. Internal IP
2. External IP
3. Instance ID
4. Tags

and much more other information associated with your terraform resource which can help automate your infrastructure code.

In this lab session, we are going to create a Terraform Data source to fetch the public IP of an EC2 instance. But similar terraform script can be written for other cloud resources such as S3 Bucket, IAM Rule, etc.

Excellent Video, not sure why the views are less, Perfect teaching, now i understand clearly about the data source

Rahul, the main purpose of terraform data source is to read the resources created outside of terraform (Not in the same .tfstate file). If we create the resource using the same terraform file then we can read them directly e.g. No need to go for data source. Or your intent was to create the resource outside of the terraform but you reduced the efforts and created using the same script? Correct me if I am wrong.

This Playlist is awesome. Eagerly waiting for more topics. If possible please share a few demos over GCP as well.

[kushelg]

Appreciate the playlist. Really helping me prepare for my interview

[Devopsyed]

I am getting very much benefitted through your playlist. Examples are clear and very easy to understand.. would suggest to make a video of quick run up on certification questions, as there is fewer content on certifications aspect for Terraform. Thanks a lot :)

[prasadrao]

Many thanks for great video, Simple and the Best

[rahulkumarshaw]

I had basic knowledge in terraform and always find difficulties to understand this to advance knowledge of terraform. You made it very simple .Good work keep it growing like this.

Hi Sir,
Thanks you for the video.
I have small doubt for returning values we use data source but
same this we can get through output also right?
thank you

[madhunallagarla]

Excellent explanation with clear instructions. Thank you so much, Rahul. By the way, has anyone ever told you that you resemble Sundar Pichai? To me, you look just like him. :)😄😃

Hi Rahul, thanks for the sharing. I'm using data source to fetch the instance ids. When I create cloudwatch dashboard and wanna refer to each values of data.aws_instances.XX.ids, how can I write the code? I use ${data.aws_instances.XX.ids[0]}, and there should be a better way I guess.

Hey Why not use Output variables? than Data resource in this scenario

[karthik]

Question - How do you pass a parameter to aws lamda in terraform . Essentially I created aws managed active directory, I need to pass the directory_id as a parameter to aws lambda( created outside of terraform by some body) which creates aws log group and subscription. My question is how to pass the parameter to aws lambda using terraform with that parameter lambda executes

[datainference]

can u please make a video on how we should handle keys in production environment

[gurpreetgill]

Hi Rahul, Could you please help how to export data from one source to another using terraform with example( instead of AWS)? I am using commercetools with terraform in which import I run successfully.

[nitmig]

can anyone tell me how to output list of ec2 instances of type t2.micro using data sources and filters, running on my aws account

[Midhunchowdary]

Could you please create a video on loops like count etc to create/refer multiple resources of same pattern .. Thanks very much for the videos

[naanireddy]

I have an vpc and subnet and I have a public IP in aws. I want to create an instance in the existing VPC and existing subnet and ec2 instance have attach my public Ip i have in aws. Could you please help me on that using terraform.

[showripratury]

"myawsinstance" in the data section referring to which name? i mean already there a resource- EC2 instance created with the name "Ec2_example" in the previous section right? can you please clarify this point.

[nagamohan]
