There are unofficial builds at https://github.com/querycap/istio, and it seems like it's got to a point (with Envoy now supporting arm64) that it could be upstreamed. I'll keep track of it for you!

their tutorial [1] is a bit unclear on which Pi's can be used - I have a stack of pi zeroes not doing anything at the moment. Do you happen to know if they could handle it (just for a learning project at home).

The docs say recommended 4gb memory, but could I run a huge swap partition for that?
