This comment made/makes me steer away https://github.com/rkt/rkt/issues/3912 There is another open issue claiming the project is dead (but maybe it's just stable) My whole team is onboard with docker, and we don't need account to install/use.
Why do you believe that churn is a good thing, especially for a thin wrapper around Linux namespaces? There should not be much this is actually doing, so lots of commits would be worrying.
The github-issue and a sibling are folks asking this question. Why? Lingering bugs? Waiting for features? That the question is open is the concern.
And again, compared to my existing tooling which is not having that question and has momentum.
Evaluated against docker (a recent move for us) but didn't choose. We also looked a "roll your own" type solutions - required expertise our team didn't have.
