AWS ARN services

arn.services

A utility service for Amazon Resource Names ( ARNs ), providing the functionality as listed below. You can consume it as an online service via https://arn.services or run it yourself as a SAM application , see details below in thesection.

Use it

ARN Services has two features: you canbreak up an ARN into its componentsand you cangenerate an ARN from its components. There are at the moment no semantic checks done, however for the generate/ endpoint some defaulting is provided.

Compartmentalize

In order to break up an ARN into its components (or: compartmentalize), use an HTTP GET on explode/$ARN , for example:

$ curl -s https://arn.services/explode/arn:aws:s3:us-west-2::abucket | jq .
{
  "Partition": "aws",
  "Service": "s3",
  "Region": "us-west-2",
  "AccountID": "",
  "Resource": "abucket"
}

Generate

To generate a fully qualified ARN from (certain) components, use an HTTP POST to generate/ , for example:

$ curl -s -X POST \
       -H "Content-Type: application/json" \
       -d '{"Service":"s3", "Resource":"somebucket/someobject"}' \
       https://arn.services/generate
arn:aws:s3:us-west-2::somebucket/someobject

Run it yourself

If you want to run ARN services yourself, you need to:

1. clone this repo (using git clone https://github.com/mhausenblas/arn.services.git for example)
2. create an S3 bucket for the Lambda functions and change the value of ARNS_BUCKET to your own S3 bucket in the Makefile
3. execute make deploy
4. OPTIONALLY: set up API Gateway and Route 53 for a custom domain and run make up ARNS_ACM_CERT=$ARNS_ACM_CERT with the ARN of the ACM cert (I did email validate for my Namecheap domain).
