- How Terraform Works
Scenario-1
- Write a Terraform configuration to deploy application with ntier architecture in AWS
- As a first step lets try to create the following network in AWS
- Configuring AWS Authentication using shared file
- Ensure you have the following directory and file
~/.aws/credentials - In this file
[default] aws_access_key_id = <your access key id> aws_secret_access_key = <your secret access key> - If we follow this approach credentials are store outside of terraform configuration.
- If you dont want to create this file manually. Install aws cli Refer Here
- Ensure you have the following directory and file
- Refer Here for the configuration written in the class
- Now we executed
terraform init
terraform validate
terraform apply
- Lets try to create one subnet
- For any resource we have arguments where we provide inputs and when the resource is created successfully it will have outputs which are referred as attributes
- To use attributes we have a syntax
<resource-type>.<name>.<attribute> - Refer Here for the changeset where we have created websubnet
- Exercise: Try to create app and db subnet
