I find k8s makes having replicas available very, very tempting. Don't fall into it (I try not to, btw). For me the good part is beign able to rollback a deployment... if you have a large base. Also, be careful with what's inside your containers. Even small distros like Alpine have security bugs. Make sure you can upgrade the container with your app on in at least every 2-3 months (less is better, btw).
