I love that we can just deploy our code in one place, but different applications work together even better than before with k8s! it's so easy to use as well compared to other systems i have used previously (like docker compose). It is very simple for someone like me who has no experience using this type of tool yet! Honestly? Nothing at all. If you are looking for an easier way then Kube does exactly what your trying to do without having to learn everything yourself or be stuck doing things manually each time there is something new added into production. The ability yo add multiple services side-by-side allows us flexibility when making changes while still knowing its being monitored closely throughout the entire process. I'm using kubernete in multiple projects with very good results so far. The support is great, they have all you need to get going fast! Nothing really; It does what it promises and works flawlessly for my needs at this time. If your looking into containers there's no better choice than Kube-Dev server from cloudcontrol.com The speed of deployment, minimal overhead makes getting up an running easy as pie.
