With Docker you have the binary running inside something like Alpine Linux. Services (like Database) are connected through a DNS-discovery agent (like Consul) and this whole shebang is managed through something like Nomad. They are all Hashicorp products, by the way, and kind of the evolution from Vagrant. (Ps: It's also quite of a heavy learning curve to move to such setups).
