The best part about habitat, it's community driven features which are not readily available in other tools (like docker). I used to use k8s before but had issues with getting up an running quickly so moved away from Kube for container orchestration as well. Now moving back towards Docker ecosystem only because of great support by developers at helm team! Nothing much yet we have been using this since early 2018 now without any issue or downtime what ever happened within our org. Would like more control over ingress rules though its pretty easy configuration through UI if you know your way around yaml/json file formats very good tool overall nothing else really liked anything specific here would love some new releases coming out soon!! Managing multiple environments across dev / test & prod infra was never problem till couple years ago when containers came into play i think! Deploying same application codebase via different environment has always made my headache :).
