Containers & orchestration approaches

docker● “Industry 3.0” of Software Development

● “Infrastructure-as-code” DevOps Practice

● Infra Cost Optimisation(Storage/VM)

● Binary/Byte + Hosting/OS Dependencies

● Identical dev-test-staging-prod...

Docker 1.12● Swarm-mode: Orchestration built-in,

Infra-agnostic

● Cryptographic Node Security: Mutual TLS, Key

rotation, Notary & TUF

● Routing Mesh: Service Discovery, Container

native load-balancing, Works with current LB,

IPVS

docker-Dev. Env.- “Local” Development Environment

- Lightweight vs. Vagrant

- Local vs. Prod identical

- “Infra-as-code” DevOps practice

ORCHESTRATORS

dockerhttps://github.com/docker/example-voting-app

Docker datacenter- On-premises & cloud

- UCP (Universal Control Plane): Deploy&Manage Apps

- Docker Trusted Registry: Secure Images

Docker datacenter - deploy?● Set ENV for remote deploy:

○ DOCKER_HOST=tcp://kloiaclbpiplabel.westeurope.cloudapp.azure.com:443

○ DOCKER_TLS_VERIFY=1

○ DOCKER_CERT_PATH=/Users/dsezen/code/example-voting-app/ucp

● Convert docker-compose.yml to “dab”:○ docker-compose bundle

● Deploy via cli:○ docker deploy votingappdocker

Mesos● Apache Foundation Project

● C++

● Uber, Samsung, Verizon, Autodesk, Azure,

Twitter, Airbnb, Yelp, Ebay, Apple…

Mesos - marathon● Orchestration - Deploy

● Scala

● Service Discovery

● Event Subscription

● Docker natively supported

Mesos - OTHER● Chronos: Java, Replacement for cron

● Aurora: Twitter, Marathon + Chronos

● Mesosphere: DC/OS

Mesos - DC/OS● “DataCenter Operating System” abstracts resources such as CPU, RAM, and networking

● Distributed Operating System based on the Apache Mesos

● Embedded Marathon, Chronos

#dcos package install spark

#dcos cluster resize 100

Mesos - DC/OS - deploy?● dcos cli:

○ dcos marathon group add votingapp.json

● REST API:

○ curl -X POST http://10.141.141.10:8080/v2/apps -d @basic-3.json -H "Content-type: application/json"

rancher● Orchestration-agnostic: Swarm, Kubernetes, Mesos, Cattle

● Infra-agnostic: on-premises, public-cloud

● Open Source
