- 40. Docker Hub Cloud Portability Use case 40 Amazon AWS Google Cloud Microsoft Azure Digital Ocean Deployment Tool Docker, Swarm, Drone.io, Flocker, Tutum, etc SAAS Company Github 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
- 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
- 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
- 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=<node_ip:2375> token://<cluster_id> • #Run Docker commands on swarm docker -H tcp://<swarm_ip:swarm_port> 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
- 62. IAAS/PAAS Adoption • Amazon ECS – Container service – Supports tasks configuration • Google Cloud – Based on Kubernetes • Microsoft Azure 62 www.synerzip.com
