AWS Tutorials

Review a saved Terraform plan, apply an in-place storage change, repair readable tag drift, and preserve existing report bytes.

Configure S3 versioning with Terraform, publish two reports, read an old version without changing the current one, and deliberately clean owned history.

Deploy two private report stores from one Terraform template, use separate inputs and local states, and verify stored report bytes.

Use Terraform references to grant an independent reader access to one report, reject unrelated reads, and revoke the grant without deleting data.

Create a private S3 bucket with Terraform, compare configuration with AWS and state, and remove only your managed resource.

Rename a Terraform resource address with a moved declaration while preserving the existing S3 bucket and original report.

Migrate local Terraform state to a versioned S3 backend without recreating report storage, then distinguish stack cleanup from backend cleanup.

Correct an environment backend binding, preserve both valid states and original reports, and prove a preview change leaves dev unchanged.

Observe real Terraform writers sharing one S3 state, reject a competing plan for its native lock, and continue safely after normal release.

Define typed Terraform module inputs and outputs, call the module from two roots, and extend stable report keys without replacing existing data.

Import an existing S3 bucket into Terraform, review a non-destructive configuration alignment, and preserve the original report and neighboring storage.

Use a supplied local module to update an application tag, review and apply an instance replacement, and retain external report data and the reference environment.

Read a prepared AMI with a Terraform data source, launch an EC2 instance in a supplied network, initialize its application with User Data, and verify its actual response.

Connect an EC2 application to an IAM role and instance profile, grant scoped private-report access with Terraform, test revocation and clean up the managed resources.

Define a VPC and subnet with Terraform references, inspect their actual CIDR and Availability Zone, and remove your stack while preserving a reference network.

Use Terraform to connect an application subnet to an internet gateway, permit the intended client on its application port, and prove that unrelated access remains blocked.

Write Terraform input validation and plan-mode module tests that catch incorrect outputs and tags while preserving existing report storage.

Add formatting and validation gates to a Terraform job, observe real failures stop planning, and preserve existing report storage.
