If you’re feeling that it will take too much time to maintain something you’re deploying, then there may also be toolset/skillset mismatch. Take Docker/K8s that you’ve called out for example; they’re the graduated steps to deploy things in the industry. Things deployed via Docker drastically reduces the amount of time to get up and running by eliminating large swaths of dependency management, as well as gives option to use tools on platform to manage self updates if that’s something desired (though this could potentially introduce failures by manual upgrade steps where required). You’d graduate to k8s as your infrastructure footprints start to grow. Learning the correct tools could potentially reduce the barrier to entry and time requirements on the apps front.

Having said that, it is probably better to ask the inverse: what is it that you’re trying to achieve and why?

Without a reason that resonates well with you, you’re not going to find time in your allegedly already life to maintain to keep it working. Nor will you be willing to find the time to learn the correct tools to deploy these things.
