Notification: Changes to Wireguard image tags

We will shortly be making changes to the tags available for our Wireguard image.

Currently we offer two tags: latest and alpine. The former uses our Ubuntu base image and contains all of the tools and dependencies required to compile the Wireguard kernel modules from scratch if your host kernel is too old to have it built-in. The latter uses our Alpine base image and does not contain the build tools and dependencies, which means it will only work on hosts that already have the Wireguard kernel modules installed and running.

Almost all kernel builds since 5.6 come with Wireguard included, along with some older ones that have had it backported, which means that shipping an extra 800Mb of image by default to support those running old kernels is increasingly unnecessary.

As a result, we’re going to switch our tags around to make the Alpine-based image the default.

• If you’re currently using the latest tag you’ll soon automatically get switched to the Alpine-based build.
• If you’re currently using the alpine tag you’ll need to switch to latest to continue receiving updates.
• If you’re still running an old kernel and need the build support, you’ll need to switch to the legacy tag.
