Docker - Layering
• Container = Writeable layer 

• Image = Static layers

• Containers = Share the kernel

Containers are here to stay!
The Open Container Initiative (OCI) is
a collaborative project hosted under
the Linux Foundation designed to
establish common standards for
containers.
Docker
• What is docker ?
• What’s more ?
Docker Hub - Public Library
Docker Registry - Private Library
Docker Registry - Private Library
• Tightly control where your images are being stored
• Fully own your images distribution pipeline
• Integrate image storage and distribution 

tightly into your in-house development workflow
• Collaborate with your colleagues
Docker Hub
• Docker HUB = Docker Registry - As A Service
• Zero Maintenance
• Additional Functionality to increase collaboration
• Alternative Providers : Google / AWS / CoreOS

framework
Virtual Pool of Resources
(CPU, RAM, …)
• Set up in seconds, integrates in the AWS stack (ELB, CloudWatch, ECR)
and yes, specific to Amazon WebServices
• Basic capabilities out of the box (no Discovery, …) but extensible
• Ideal for simple containerised workloads
• Opinionated declarative cluster management solution
• Runs on a single machine (in Docker) and on a large datacenter setup
• Rich API for cluster management
• Support for Secrets, Quota, Volumes, …
• Provider agnostic (docker, rkt, amazon, gce, …)
• Abstracts a cluster behind the Docker Remote API
• Networking and scheduling support
• Open plugin points for discovery, networking, …
• Docker only
• Lacks (being out of the box) service load balancing support
• Essentially a resource abstraction
• Scales to +10K nodes
• Job agnostic (more than containers alone)
• Support Kubernetes as one of the many frameworks
+

  • 74. • Set up in seconds, integrates in the AWS stack (ELB, CloudWatch, ECR) and yes, specific to Amazon WebServices • Basic capabilities out of the box (no Discovery, …) but extensible • Ideal for simple containerised workloads • Opinionated declarative cluster management solution • Runs on a single machine (in Docker) and on a large datacenter setup • Rich API for cluster management • Support for Secrets, Quota, Volumes, … • Provider agnostic (docker, rkt, amazon, gce, …) • Abstracts a cluster behind the Docker Remote API • Networking and scheduling support • Open plugin points for discovery, networking, … • Docker only • Lacks (being out of the box) service load balancing support • Essentially a resource abstraction • Scales to +10K nodes • Job agnostic (more than containers alone) • Support Kubernetes as one of the many frameworks
