@robi / others interested
I have revisited the Zeronet repo / build.
Should now be a working vanilla Zeronet Conservancy deployment.
v2.0.0
repo : https://git.cloudron.io/timconsidine/cloudron-zeronet
docker image : tcmbp132021/cloudron-zeronet:v2.0.0
Not 100% sure it's done, because I still don't get Zeronet - excellent idea, but mostly old/stale sites, does anyone actually use Zeronet , maybe it's a "time to sync" issue, which I don't have enough patience for.
But check it out
