Python CLI for tagging AWS resources based on a YAML configuration

Awstaga

Awstaga is a Python CLI for tagging AWS resources based on a YAML configuration.

Installation

pip3 install awstaga

Usage

Create a configuration file, e.g. awstaga.yaml:

---
tagsets:
  - name: common
    tags:
      - key: CostCentre
        value: FIN-123
      - key: Organisation
        value: World Enterprise
      - key: Description
        value: AWS Resource
  - name: prod
    tags:
      - key: EnvType
        value: prod
      - key: Availability
        value: 24x7
  - name: nonprod
    tags:
      - key: EnvType
        value: non-prod
      - key: Availability
        value: on-demand
resources:
  - arn: 'arn:aws:ssm:ap-southeast-2:123456789012:document/high-avail'
    tags:
      - key: Description
        value: High availability SSM document
    tagsetnames:
      - common
      - prod
  - arn: 'arn:aws:s3:::world-enterprise/development/logo.jpg'
    tags:
      - key: Description
        value: World Enterprise logo
    tagsetnames:
      - common
      - nonprod

And then run awstaga CLI and pass the configuration file path:

awstaga --conf-file awstaga.yaml

It will write the log messages to stdout:

[awstaga] INFO Loading configuration file awstaga.yaml
[awstaga] INFO Loading 3 tagset(s)...
[awstaga] INFO Loading 2 resource(s)...
[awstaga] INFO Adding resource arn:aws:ssm:ap-southeast-2:123456789012:document/high-avail to a batch with tags {'CostCentre': 'FIN-123', 'Organisation': 'World Enterprise', 'Description': 'AWS Resource', 'EnvType': 'prod', 'Availability': '24x7', 'Description': 'High availability SSM document'}
[awstaga] INFO Adding resource arn:aws:s3:::world-enterprise/development/logo.jpg to a batch with tags {'CostCentre': 'FIN-123', 'Organisation': 'World Enterprise', 'Description': 'AWS Resource', 'EnvType': 'prod', 'Availability': '24x7', 'Description': 'World Enterprise logo'}

You can run Awstaga in dry-run mode by adding --dry-run flag:

awstaga --conf-file awstaga.yaml --dry-run

During dry-run mode, Awstaga log messages will be labeled with [dry-run]:

[dry-run] [awstaga] INFO Loading configuration file awstaga.yaml
[dry-run] [awstaga] INFO Loading 3 tagset(s)...
[dry-run] [awstaga] INFO Loading 2 resource(s)...
[dry-run] [awstaga] INFO Adding resource arn:aws:ssm:ap-southeast-2:123456789012:document/high-avail to a batch with tags {'CostCentre': 'FIN-123', 'Organisation': 'World Enterprise', 'Description': 'AWS Resource', 'EnvType': 'prod', 'Availability': '24x7', 'Description': 'High availability SSM document'}

Awstaga supports YAML includes using , so you can split your configuration into multiple files:

---
tagsets:
  - !include include.d/tagset.yaml
resources: !include include.d/resources.yaml

Include files should be put under `include.d/`` folder relative to the configuration file.

The included tagset file include.d/tagset.yaml:

---
name: common
tags:
  - key: CostCentre
    value: FIN-123
  - key: Organisation
    value: World Enterprise
  - key: Description
    value: AWS Resource

The included resources file include.d/resources.yaml:

---
- arn: 'arn:aws:ssm:ap-southeast-2:123456789012:document/high-avail'
  tags:
    - key: Description
      value: High availability SSM document
  tagsetnames:
    - common
    - prod
- arn: 'arn:aws:s3:::world-enterprise/development/logo.jpg'
  tags:
    - key: Description
      value: World Enterprise logo
  tagsetnames:
    - common
    - nonprod

In order to optimise the number of API calls, the resources are put into batches depending on the tags. By default, the batch size is 100. You can run Awstaga with a custom batch size --batch-size <number> flag:

awstaga --conf-file awstaga.yaml --batch-size 50
