s3-parse-url 0.3.0

A small tool to parse URLs for S3 compatible storage services

---

Parses S3 credentials from the given string and returns it in comfortable format to pass to popular clients like boto3.

About

This is a small utility to parse locations of buckets of S3-compatible storage (and, of course, the original Amazon’s S3 itself) given in the URL form like s3://bucket/.

It could be useful in our epoch of the 12-factor applications when it’s a good practice to store credentials inside of environment variables.

Also, these days, there are some notable S3-compatible storage services:

• Selectel

• MinIO (a self-hosted solution extremely handy for testing)

And dozens of others.

With s3-parse-url, you can use any one of these services with no doubts about configuration endpoints. For example, you can connect to your Selectel storage with boto3 just using selectel://my-bucket DSN.

That’s an example, what it was all about:

from s3_parse_url import s3_parse_url
from s3_parse_url.ext.clients import get_boto3_client

dsn = "s3://AKIA***OO:XP***@my-bucket/?region=us-east-2"

# It's a completely ready boto3 client instance to work with Selectel
s3_client = get_boto3_client(dsn)

Of course, in the code above we worked with Selectel (have you ever heard about it?). You can work this way with any S3 compatible storage. If you prefer unknown storage, you can easily create a plugin to add support for your favorite service. Or, if you are a pervert, you can use a universal S3:// scheme, but in this case, you should manage endpoints by yourself:

from s3_parse_url.ext.clients import get_boto3_client

# Also should work
dsn = "s3://my-minio-user:[e-mail]:9000/?region=us-east-1"

# A ready client to work with a minio instance
s3_client = get_boto3_client(dsn)
