Lab Information
The Nautilus DevOps team has some volumes in different regions in their AWS account. They are going to setup some automated backups so that all important data can be backed up on regular basis. For now they shared some requirements to take a snapshot of one of the volumes they have.
Create a snapshot of an existing volume named nautilus-vol in us-east-1 region using terraform.
1) The name of the snapshot must be nautilus-vol-ss.
2) The description must be Nautilus Snapshot.
3) Make sure the snapshot status is completed before submitting the task.
The Terraform working directory is /home/bob/terraform. Update the main.tf file (do not create a separate .tf file) to accomplish this task.
Note: Right-click under the EXPLORER section in VS Code and select Open in Integrated Terminal to launch the terminal.
Lab Solutions
Update the main.tf file with the complete solution:
# main.tf
resource "aws_ebs_volume" "k8s_volume" {
availability_zone = "us-east-1a"
size = 5
type = "gp2"
tags = {
Name = "nautilus-vol"
}
}
# Create snapshot of the existing volume
resource "aws_ebs_snapshot" "nautilus_snapshot" {
volume_id = aws_ebs_volume.k8s_volume.id
description = "Nautilus Snapshot"
tags = {
Name = "nautilus-vol-ss"
}
}
To deploy this configuration:
Navigate to the Terraform directory:
cd /home/bob/terraform
Initialize Terraform:
terraform init
Output
bob@iac-server ~/terraform via 💠 default ➜ terraform init
Initializing the backend...
Initializing provider plugins...
- Reusing previous version of hashicorp/aws from the dependency lock file
- Using previously-installed hashicorp/aws v5.91.0
Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
Plan the deployment to verify the configuration:
terraform plan
Output
bob@iac-server ~/terraform via 💠 default ➜ terraform plan
aws_ebs_volume.k8s_volume: Refreshing state... [id=vol-523a81e2e11961950]
Terraform used the selected providers to generate the following execution plan. Resource
actions are indicated with the following symbols:
+ create
Terraform will perform the following actions:
# aws_ebs_snapshot.nautilus_snapshot will be created
+ resource "aws_ebs_snapshot" "nautilus_snapshot" {
+ arn = (known after apply)
+ data_encryption_key_id = (known after apply)
+ description = "Nautilus Snapshot"
+ encrypted = (known after apply)
+ id = (known after apply)
+ kms_key_id = (known after apply)
+ owner_alias = (known after apply)
+ owner_id = (known after apply)
+ storage_tier = (known after apply)
+ tags = {
+ "Name" = "nautilus-vol-ss"
}
+ tags_all = {
+ "Name" = "nautilus-vol-ss"
}
+ volume_id = "vol-523a81e2e11961950"
+ volume_size = (known after apply)
}
Plan: 1 to add, 0 to change, 0 to destroy.
─────────────────────────────────────────────────────────────────────────────────────────
Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to
take exactly these actions if you run "terraform apply" now.
Apply the configuration:
terraform apply
Then type yes when prompted to confirm the creation of the snapshot.
