Docker Nginx Certbot Versions Save

• Lock certbot version via a requirements.txt file.
  • Updates to the certbot version will now bump patch version of this repo.
• Added "bunny" DNS to available authenticators
  • PR by @chreniuc

• We now run nginx -t before reloading Nginx. This will hopefully provide better info on config errors without crashing the container.
  • The reason for this being a major version is because technically we alter core container behavior where previous errors would result in a restart.

• Parent image is now using Python 3.11 which implements PEP 668, so we have to allow set the bulid argument PIP_BREAK_SYSTEM_PACKAGES=1 so it is possible to install PIP packages again.

• Require all certificate files to have a size greater than zero.

• Add Ionos DNS authenticator plugin

• Install Bash 5.2.15 from Debian Bookworm.
  • Workaround for this Bash bug which we also had in the Alpine image.
  • Not using a "backport" repository is not recommended, but right now the only way.
• Added timestamps to the log output we produce.
  • This is technically a breaking change if someone parses our logs, but I will ignore that.

• New approach to implementing IPv6 support for the HTTP-01 challenge.
  • Deleted the dedicated server in certbot.conf

This change should be transparent for anyone not having a custom certbot.conf file, but is technically making a breaking change for someone, thus a major revision bump.

• Revert previous feature after it apparently breaking some setups.

• Have the server in certbot.conf listen on IPv6 as well.
  • PR by @Meptl.

• Small syntax fixes recommended by shellcheck.
