Walkthrough

Walkthrough

The introduced changes enhance the Let's Encrypt service by adding support for DigitalOcean DNS challenge authentication. The script now checks if the CHALLENGE environment variable is set to "dns" and if the DNS_PROVIDER is "dns-digitalocean." If these conditions are met, it requires a DigitalOcean API token, sets necessary provider arguments, and applies propagation settings, expanding the service's capabilities for DNS verification.

Changes

File Path	Change Summary
letsencrypt/.../lets-encrypt/run	Added support for DigitalOcean DNS challenge authentication, including conditional logic for dns-digitalocean and requirements for API token and provider arguments.
letsencrypt/CHANGELOG.md	Updated to version 5.0.25 to reflect DigitalOcean's propagation-seconds feature and note previous fixes for Gandi DNS support.
letsencrypt/config.yaml	Incremented version from 5.0.24 to 5.0.25, indicating enhancements or bug fixes without changes to other fields.

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:

@peakascendr thanks for your PR!

This needs a bump of the version in config.yaml and an update in the CHANGELOG.md so it will lead to a new add-on release.
