DOCKER

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

What is a Container? 22 Virtual Machine Container Using namespace, cgroups, apparmour, etc.

What is Docker? 23 Docker Client Docker Daemon Public Repo Private Repo Docker File DSL

Docker File System 24

Dockerfile FROM dockerfile/node  Base Image RUN apt-get update –qq  Instructions RUN mkdir /my/app  while building image ADD. /my/app CMD [“node”,”web”]  What Command to run 25

Dockerfile //Build an Image $> docker build –t “rohitghatol/node”. //Run an Image $>docker run –d –p 80:3000 rohitghatol/node //Push to Docker Hub $>docker push rohitghatol/node//developer $>docker pull rohitghatol/node//operations 26

Developer Scenario 31 Dev Box Dev Rails Image Rails Image Docker Hub Docker Hub Web (RoR) Web (RoR) Dev 1. Pull 2. Run 3. Customize 4. Push as Base Image Team 5. Pull

Developer Scenario 32 Dev Box Dev Host Machine (Developer codes here) Host Machine (Developer codes here) Docker Web (RoR) Web (RoR) DB (MySQL) DB (MySQL) ~/app/src./src IDE, Browsers, etc => Docker Hub Docker Hub Sync Folder Code runs here

CI Scenarios 33 Code Push Test Code Test Feature Build App Docker Image Run Docker Container with App Image Publish App Docker Image Numerous combinations… Pull Code

CI Scenarios – Option 1 34 Code Push Pull Code Test Code Publish App Docker Image Build App Docker Image

CI Scenario 35 Github Docker Web (RoR) Web (RoR) DB (MySQL) DB (MySQL) Docker Hub Docker Hub Dev Box Dev 1. Push Code 2. Listen 3. Get Base Image 5. Run Tests 4. Pull Code 6. Build App Image 7. Push App Image CI Server ( Drone, Shippable, Circle CI, CodeShip, Travis CI, Jenkins etc) CI Server ( Drone, Shippable, Circle CI, CodeShip, Travis CI, Jenkins etc)

CI Scenarios – Option 2 36 Code Push Test Feature Build App Docker Image Run Docker Container with App Image Publish App Docker Image Mark Good App Image

CI Scenario 37 Github CI Server (Drone.io, inhouseCI, etc) CI Server (Drone.io, inhouseCI, etc) Docker Web (RoR) Web (RoR) DB (MySQL) DB (MySQL) Docker Hub Docker Hub Dev Box Dev 1. Push Code 3. Listen 2. Create App Docker Image 5. Run Tests 4. Pull Run App Image 6. Accept/Reject Image

Staging/Prod Scenario 38 Host Machine Docker Container Web (RoR) Web (RoR) DB (MySQL) DB (MySQL) Docker Hub Docker Hub 1. Trigger Event 3. Pull App Image 4. Run Image 2. Deploy Docker Container (AWS, Azure, Digital Ocean, etc.) Host Machine

CLOUD PORTABILITY 39

Docker Hub Docker Hub Cloud Portability Use case 40 Amazon AWS Google Cloud Microsoft Azure Digital Ocean Deployment Tool Deployment Tool Docker, Swarm, Drone.io, Flocker, Tutum, etc SAAS Company SAAS Company Github

MEAN STACK 41

MeanStack Use case 42 Open-Source Full-Stack Solution for MEAN Applications

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

MeanStack Use case 44

MeanStack Use case 45 WebDB Port 3000 Port Docker Containers fig.yml

MeanStack Use case 46 dockerfile/nodejs Image grunt-cli bower package.json ….. Dockerfile

MICRO SERVICES 47

Micro Services Use case 48 Micro Service Recomm Engine Node Mong o Solr Recomm Engine Movie Listing Play PSql Movie Listing Profile RoR My SQL My SQL Redis Profile Preference RoR Redis Preference

……… Micro Services Use case 49 Recomm Engine Movie Listing Profile Preference Sprint 1Sprint 2Sprint 7 Sprint 1Sprint 2 Sprint 1Sprint 2Sprint 3 Sprint 1Sprint 2Sprint 3 ……… Deploy

Micro Services Use case 50 Recomm Engine Node Mong o Solr Recomm Engine Docker Container Gateway/Re v Proxy

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

Micro Services Use case What else is needed? –Scheduling –High Availability –Service Discovery –Etc. 52 Giant Swarm By Invite

FUTURE OF DOCKER 53

NEW DOCKER PRODUCTS 54

New Docker Products Docker Machine Docker Swarm Docker Compose 55

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

Docker Machine $>docker-machine create -d virtualbox dev $>docker-machine create -d digitalocean -- digitalocean-access-token=... staging 57

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

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

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

IAAS/PAAS ADOPTION 61

IAAS/PAAS Adoption Amazon ECS –Container service –Supports tasks configuration Google Cloud –Based on Kubernetes Microsoft Azure 62
