Docker vs Kubernetes vs DC/OS vs ECS

This document compares the four container orchestration frameworks: Docker Engine w/ Swarm Mode, Kubernetes, DC/OS, and ECS.

Feature	Docker	Kubernetes	DC/OS	ECS
Local Development	Docker Community Edition	minikube	DC/OS Vagrant	Blox
Multiple clouds	Docker Cloud, Docker Machine Drivers, Docker for AWS/Azure	Turn Key Cloud	Mulitple clouds	AWS
Service Discovery and Load Balancer	Docker-compse: DNS Docker Swarm: (Service)	Service	Yes (multiple: DNS-based and proxy-based/L4 load balancer)	DNS-based, ELB-based, ALB-based
Dynamic Scaling	Services, Distributed Application Bundle, Stack	Replica Set, Replication Controller, Deployment, Horizontal Pod Autoscaling	Marathon app spec (instance count) and multiple options	Service Auto Scaling
Exposing a service	Routing mesh	type=LoadBalancer in Deployment	Multiple (direct placement on public agent or, preferred, via Marathon-LB	Classic and Application Load Balancer
Run-once job	docker run	Job	Jobs	Tasks
Namespace	docker-compose -p <namespace>	Namespace	via labels in System Marathon	Custom Attributes
Global service	--mode=global	DaemonSet	Unique Attribute	'distinctInstance' Task Placement Constraint
Maven	fabric8-maven-plugin	fabric8-maven-plugin	dcos-maven-plugin	No
Volumes	Docker Volumes	Persistent Volumes	local persistent volumes as well as external persistent volumes	Using Data Volumes in Tasks
Multiple Master	Yes	Yes	Yes	Yes (default)
Multi-host networking	Yes	Yes	Yes	Proposed implementation
Rolling Update	https://github.com/arun-gupta/docker-scripts/blob/master/rolling-updates.adoc	https://github.com/arun-gupta/kubernetes-java-sample/tree/master/rolling-update	ZDD Lab	Updating a Service
Container distribution strategies	Automatic?	Automatic, but custom schedulers supported.	Automatic	Task Placement Strategies
Affinity	Labels	Node (1.2) and Pod (1.4) affinity http://kubernetes.io/docs/user-guide/node-selection/	Marathon constraints and pods (in 1.9)	Via Task Placement Strategies and Constraints
Constraints	-c, -m	Labels	Marathon constraints	Task Placement Constraints
On-premise	Yes	Yes	Yes	No
Cluster across multiple clouds	Yes	Yes (partly)	Yes (agents)	No (Can span multiple AZ)
Commercially supported	Docker Enterprise Edition	Google, Apprenda, Canonical, CoreOS, Cloud RTI others?	Mesosphere Enterprise DC/OS	AWS Support
Creating Couchbase Cluster	blog	blog	blog	blog (one node)
