Clarification regarding server requirements for Linux and Kubernetes on LKE

in flag

I want to Dockerize my applications(stack: react, nginx, node, mongodb, redis etc) and deploy them on VPS/s on Linode, but I never done anything like that before and have some fundamental questions regards it and hope you can help me clarify them.

  1. For a 1 vCPU and 1gb RAM server, what linux distro should I choose in terms of low RAM usage, security and ease of use(as I'm very new and all tutorials are based on popular options)? Ubuntu as I get it, requires at minimum 512MB of RAM. I will also need to run Docker(multiple) for each service(react, node, mongo etc). How people manage this on such budget machines? Please advice.

  2. Because I'm using Docker, I was reading about Linode Kubernetes Engine(LKE), but it's 3 times as expensive as 1vCPU and 1gb RAM. Also, there's no explanation on the same question above(my previous question), regarding how does each linode server(VPS) in the cluster manage its OS. Do I need to install on each of them linux distro and docker?

Thank you

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
