Ask HN: What is happening new in the container space (docker alternatives) ?

What are some cool projects you are interested in? I am primarily looking to expand my knowledge / look for alternatives to docker itself my main issue is that most of these are written in golang and though I love golang very much , I also like to see some more container tech alternatives in languages like rust / C++ though there are podman / nerdctl (Nerdctl doesn't say it to be a competitor to docker but I think someone can use nerdctl directly instead of docker) https://gitee.com/openeuler/iSulad (I just recently found) I am also looking to get to know more and cool upcoming projects in the container space since it really interests me
