DOCKER 101 20 www.synerzip.com 21. What is Docker? Docker provides Docker Daemon to run light weight containers on Linux. Applications: • Are dockerized and • Run on Docker Containers – from laptops to production servers on cloud • Their images are shared on Docker Hub • Apps can be linked (node -> mongo) 21 www.synerzip.com 22. What is a Container? 22 Virtual Machine Container Using namespace, cgroups, apparmour, etc. www.synerzip.com 23. What is Docker? 23 Docker Client Docker Daemon Public Repo Private Repo Docker File DSL www.synerzip.com 24. Docker File System 24 www.synerzip.com 25.

MEAN STACK 41 www.synerzip.com 42. MeanStack Use case 42 Open-Source Full-Stack Solution for MEAN Applications www.synerzip.com 43. MeanStack Use case • Mean.js provides – Code generator to generate Mean App – Mean.js apps typically have • Node Js Server • Mongo DB database – Provides Dockerfile and fig.yml to run the app in Docker Containers • One Docker container for Node Js Server • One Docker container for Mongo DB Database 43 www.synerzip.com 44. MeanStack Use case 44 www.synerzip.com 45. MeanStack Use case 45 Web DB Port 3000 Port 27017 Docker Containers fig.yml www.synerzip.com 46. MeanStack Use case 46 dockerfile/nodejs Image grunt-cli bower package.json ….. Dockerfile www.synerzip.com 47. MICRO SERVICES 47 www.synerzip.com 48. Micro Services Use case 48 Micro Service Recomm Engine Node Mong o Solr Recomm Engine Recomm Engine Movie Listing Play PSql Movie Listing Movie Listing Movie Listing Profile RoR My SQL Redis Profile Preference RoR Redis Preference www.synerzip.com 49. ……… ……… Micro Services Use case 49 Recomm Engine Movie Listing Profile Preference Sprint 1 Sprint 2 Sprint 7 Sprint 1 Sprint 2 Sprint 1 Sprint 2 Sprint 3 Sprint 1 Sprint 2 Sprint 3 ……… ……… Deploy www.synerzip.com 50. Micro Services Use case 50 Recomm Engine Node Mong o Solr Recomm Engine Recomm Engine Docker Container Gateway/Re v Proxy www.synerzip.com 51. Micro Services Use case • Micro services are hard to run • Needs strong DevOps process • Docker helps by – Defining container/micro service as unit – Shipping one micro service as one container – More containers = more scale – By improving Dev – Operations relationships 51 www.synerzip.com 52. Micro Services Use case • What else is needed? – Scheduling – High Availability – Service Discovery – Etc. 52 Giant Swarm www.synerzip.com 53. FUTURE OF DOCKER 53 www.synerzip.com 54. NEW DOCKER PRODUCTS 54 www.synerzip.com 55. New Docker Products • Docker Machine • Docker Swarm • Docker Compose 55 www.synerzip.com 56. Docker Machine • Machine makes it really easy to create Docker hosts on local hypervisors and cloud providers. • It creates servers, installs Docker on them, then configures the Docker client to talk to them. 56 www.synerzip.com 57. Docker Machine $>docker-machine create -d virtualbox dev $>docker-machine create -d digitalocean -- digitalocean-access-token=... staging 57 www.synerzip.com 58. Docker Swarm • Swarm is a simple tool which controls a cluster of Docker hosts and exposes it as a single "virtual" host. • Swarm uses the standard Docker API as its frontend, which means any tool which speaks Docker can control swarm transparently. 58 www.synerzip.com 59. Docker Swarm • # create a cluster $ docker run --rm swarm create • # Add Machine to cluster docker run -d swarm join --addr= token:// • #Run Docker commands on swarm docker -H tcp:// run –d –P dockerfile/node 59 www.synerzip.com 60. Docker Compose • An orchestration tool for Docker • Defines – Which Docker containers are to be run – How they are connected – What ports they expose – All in single file – Initial design based on Fig.sh • Current status - limbo 60 www.synerzip.com 61. IAAS/PAAS ADOPTION 61 www.synerzip.com 62. IAAS/PAAS Adoption • Amazon ECS – Container service – Supports tasks configuration • Google Cloud – Based on Kubernetes • Microsoft Azure 62 www.synerzip.com 63. Q & A? 63 www.synerzip.com 64. •6484 www.synerzip.com Ashish Shanker ashish.shanker@synerzip.com 469.374.0500 64 www.synerzip.com 65.
