ACME ("Let's Encrypt") client for Linode Object Storage

Automatically provision a Linode Object Storage bucket with a Let's Encrypt certificate.

Requirements

pip install cryptography requests

This assumes you have already created an Object Storage Bucket for a domain (e.g. my.bucket.domain) and configured a DNS to point to the bucket.

The bucket name and DNS name must be identical.

Generate Let's Encrypt account key:
```
openssl genrsa 4096 > account_key.pem
```
Create a Linode API Personal Access Token with Read/Write permission to Object Storage.
Provision a certificate for this bucket:
```
export LINODE_TOKEN=...
python3 -m acme_linode_objectstorage -k account_key.pem my.bucket.domain
```
The Object Storage cluster can be specified with the --cluster flag (default: us-east-1).

If this is the first time running the script, you will also need to include the --agree-to-terms-of-service flag to indicate agreement with the Let's Encrypt Terms of Service.

Certificates are typically valid for 90-days. This script should be re-run approximately 30-days prior to certificate expiration.
