I’ve been running a DigitalOcean Apps static site for Hugo using the Hugo Buildpack.

I’ve migrated a set of Hugo sites to use Hugo Modules which includes the addition of go.mod (and go.sum) files to the Hugo project in order to manage e.g. themes.

Unfortunately, the Hugo Buildpack used by DigitalOcean Apps does not support Hugo Modules. DigitalOcean support recommended that I switch to use a build with a Dockerfile. Unfortunately (!) the recommended Hugo container image (klakegg/hugo) is outdated (0.107.0). The current version is 0.111.3.
