An AWS tags checking tool that can be used to look for untagged resources, missing tags, resources with too many tags, and more.

Run checks in a dashboard:

Or in a terminal:

Getting Started

Installation

Install Powerpipe (https://powerpipe.io/downloads), or use Brew:

brew install turbot/tap/powerpipe

This mod also requires Steampipe with the AWS plugin as the data source. Install Steampipe (https://steampipe.io/downloads), or use Brew:

brew install turbot/tap/steampipe
steampipe plugin install aws

Steampipe will automatically use your default AWS credentials. Optionally, you can setup multiple accounts or customize AWS credentials.

Finally, install the mod:

mkdir dashboards
cd dashboards
powerpipe mod init
powerpipe mod install github.com/turbot/steampipe-mod-aws-tags

Browsing Dashboards

Start Steampipe as the data source:

steampipe service start

Start the dashboard server:

powerpipe server

Browse and view your dashboards at http://localhost:9033.

Running Checks in Your Terminal

Instead of running benchmarks in a dashboard, you can also run them within your terminal with the powerpipe benchmark command:

List available benchmarks:

powerpipe benchmark list

Run a benchmark:

powerpipe benchmark run aws_tags.benchmark.untagged

Different output formats are also available, for more information please see Output Formats.

Configure Variables

Several benchmarks have input variables that can be configured to better match your environment and requirements. Each variable has a default defined in its source file, e.g., controls/limit.sp, but these can be overwritten in several ways:

It's easiest to setup your vars file, starting with the sample:

cp powerpipe.ppvars.example powerpipe.ppvars
vi powerpipe.ppvars

Alternatively you can pass variables on the command line:

powerpipe benchmark run aws_tags.benchmark.mandatory --var 'mandatory_tags=["Application", "Environment", "Department", "Owner"]'

Or through environment variables:

export PP_VAR_mandatory_tags='["Application", "Environment", "Department", "Owner"]'
powerpipe control run aws_tags.control.ec2_instance_mandatory

These are only some of the ways you can set variables. For a full list, please see Passing Input Variables.

Common and Tag Dimensions

The benchmark queries use common properties (like account_id, connection_name and region) and tags that are defined in the form of a default list of strings in the variables.sp file. These properties can be overwritten in several ways:

It's easiest to setup your vars file, starting with the sample:

cp powerpipe.ppvars.example powerpipe.ppvars
vi powerpipe.ppvars

Alternatively you can pass variables on the command line:

powerpipe benchmark run aws_tags.benchmark.limit --var 'tag_dimensions=["Environment", "Owner"]'

Or through environment variables:

export PP_VAR_common_dimensions='["account_id", "connection_name", "region"]'
export PP_VAR_tag_dimensions='["Environment", "Owner"]'
powerpipe benchmark run aws_tags.benchmark.limit

Remediation

Using the control output and the AWS CLI, you can remediate various tagging issues.

For instance, with the results of the ec2_instance_mandatory control, you can add missing tags with the AWS CLI:

#!/bin/bash

OLDIFS=$IFS
IFS='#'

INPUT=$(powerpipe control run aws_tags.control.ec2_instance_mandatory --var 'mandatory_tags=["Application"]' --output csv --header=false --separator '#' | grep 'alarm')
[ -z "$INPUT" ] && { echo "No instances in alarm, aborting"; exit 0; }

while read -r group_id title description control_id control_title control_description reason resource status account_id region
do
  aws resourcegroupstaggingapi tag-resources --region ${region} --resource-arn-list ${resource} --tags Application=MyApplication
done <<< "$INPUT"

IFS=$OLDIFS

To remove prohibited tags from EC2 instances:

#!/bin/bash

OLDIFS=$IFS
IFS='#'

INPUT=$(powerpipe control run aws_tags.control.ec2_instance_prohibited --var 'prohibited_tags=["Password"]' --output csv --header=false --separator '#' | grep 'alarm')
[ -z "$INPUT" ] && { echo "No instances in alarm, aborting"; exit 0; }

while read -r group_id title description control_id control_title control_description reason resource status account_id region
do
  aws resourcegroupstaggingapi untag-resources --region ${region} --resource-arn-list ${resource} --tag-keys Password
done <<< "$INPUT"

IFS=$OLDIFS
