just start with docker first, make some images and get used to the tools. kubernetes is a lot easier to install on small hardware than dc/os (it needs like 3-5 vms minimum lol) and anyway i think mesos isn't that popular anyway from my observations. theres like a billion guides out there https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-16-04

also ive used https://hyper.sh/ to host some things like gogs. its pretty sick because the api commands are exactly like deploying/building anything on docker

A long time ago some user here was pimping his terrible windows app virtualization thing that was buggy AF. Then Microsoft bought it. https://en.wikipedia.org/wiki/Microsoft_App-V

containers and their schedulers aren't anything new. openvz and zones and yarn etc have been around forever. it's just docker made the build and image management part very easy. IRL deployment is still a major pain though unless your app is totally stateless/doesn't need any local persistence

like for example doing something as simple as saving images to a disk, in a clustered setup, is not possible. you now need an object store or some distributed storage. it ratchets up complexity a ton. most people don't need to deploy infra like this

containers are rad for production, they're just the best iteration of 30(?) years of jails with the best generic tooling so far except docker is utter trash, like the specific software is poopoo

which is why yarn/mr was married to a distributed file system by design (hdfs)

so i guess i should just keep running vms then? idk if my use-case even fits containerization which means it probably doesn't

it's really intended for large scale distributed deployments through a scheduler, running docker on your $5 vm isn't gaining anything useful. you can do all the same build automation with packer/ansible still worthwhile to learn though

also instead of 1000 project putting stuff in the public schema of one db you can have 1000 lil dbs so its almost like we're using schemas now too!
