Here’s how to create a backup vault in AWS Backup.
aws backup create-backup-vault --backup-vault-name my-efs-vault --profile default --region us-east-1 |
To delete a vault, run this command.
aws backup delete-backup-vault --backup-vault-name my-efs-vault --profile default --region us-east-1 |
This script add new tags if they are missing.
#!/bin/bash log="log.txt" id=$(aws efs describe-file-systems --query "FileSystems[*].[FileSystemId]" --output text --region us-east-1) tag=$(aws efs describe-file-systems --query "FileSystems[*].Tags[?Key=='aws-backup'].Value" --output text --region us-east-1 ) arr[0]="efs-0000" arr[1]="efs-0400" arr[2]="efs-0800" arr[3]="efs-1200" arr[4]="efs-1600" arr[5]="efs-2000" rand=$[ $RANDOM %6 ] backup=${arr[$rand]} if [[ $tag == "" ]]; then aws efs tag-resource --resource-id $id --tags Key="aws-backup",Value=${arr[$rand]} --profile default --region us-east-1 echo "Added backup tag $backup to $id" elif [[ $tag == "no-backup" ]]; then echo "No backup on $id." else echo "No changes done to $id." fi |
This command lists the EC2 instance id and the tag name using query.
aws ec2 describe-instances \ --query 'Reservations[].Instances[].[InstanceId,Tags[?Key==Name]|[0].Value]' \ --profile tfc \ --region us-east-2 \ --output text |
Output:
i-xxxxxxxxxxxxxxxxx server-one i-xxxxxxxxxxxxxxxxx server-two i-xxxxxxxxxxxxxxxxx server-three |
|[0].Value insures output is one instance record per line.
Amazon Lightsail offers a variety of OS blueprints, starting from Amazon Linux 2, Ubuntu 20, Windows Server 2019 to Debian 10 to name just a few. Blueprints are a curated selection of operating systems and software that are preinstalled for the creation of instances. For brevity, only a subset of blueprints are displayed below. The description and licenseUrl portions are truncated. To display an entire list of LightSail blueprints, run this command.
aws lightsail get-blueprints --region us-east-1 |
Output:
{ "blueprints": [ { "blueprintId": "ubuntu_20_04", "name": "Ubuntu", "group": "ubuntu_20", "type": "os", "description": "Ubuntu 20.04 LTS - Focal. Lean, fast and powerful, Ubuntu Server delivers services reliably ...", "isActive": true, "minPower": 0, "version": "20.04 LTS", "versionCode": "1", "productUrl": "https://aws.amazon.com/marketplace/pp/B087QQNGF1", "licenseUrl": "https://d7umqicpi7263.cloudfront.net/eula/product/aced0818- ... .txt", "platform": "LINUX_UNIX" }, { "blueprintId": "wordpress", "name": "WordPress", "group": "wordpress", "type": "app", "description": "Bitnami, the leaders in application packaging, and Automattic, the experts behind WordPress .... ", "isActive": true, "minPower": 0, "version": "5.6.0", "versionCode": "1", "productUrl": "https://aws.amazon.com/marketplace/pp/B00NN8Y43U", "licenseUrl": "https://d7umqicpi7263.cloudfront.net/eula/product/7d426cb7- ... .txt", "platform": "LINUX_UNIX" } } |
In this example, I’m using the query option to display only the blueprints ids.
aws lightsail get-blueprints --query 'blueprints[*].[blueprintId]' --output text --region us-east-1 |
Output:

AWS just added a new feature called CloudShell. It will give users who are logged in to the AWS console access to a VM where users can run AWS CLI commands. Permissions to AWS resources is based on the user’s permissions which are managed via IAM. CloudShell is similar to the cloud shells that Azure and GCP already offer. Here’s a snapshot of AWS CloudShell.
