The IBM Cloud @ Cork Working as part of the Cloud Foundation Services project.

Responsible for deployment of services used by Bluemix Dedicated and Local.

Varying responsibilities among different squads, from topology, to operations, and delivery pipeline.

A DevOps culture is adopted by all squads.

Delivery pipeline: A DevOps practice for using a specific set of tools for automating deployment of applications/services.

Bluemix Dedicated/Local Aside from existing public cloud model, Bluemix is now offered with

dedicated and local models.

Dedicated: A private cloud. Bluemix is deployed on cloud resources which are not shared with other customers.

Local: An on-premise private cloud. Bluemix is deployed on the hardware resources at the customer’s location.

Hybrid: Customer can use both dedicated and local models for different applications.

The ToDo item cannot be deleted from here on the app website; the RESTful HTTP DELETE call is only available to an authenticated mobile user via the Mobile app, which uses the “Mobile Client Access” service to authenticate the user using Google or Facebook.

CLOUDACADEMY

Tapping and holding the completed task starts the delete operation…

…but the user has not authenticated (a 403 Forbidden HTTP response was received), so the user is directed to Facebook to authenticate.

CLOUDACADEMY

© 2016 IBM CorporationIBM Bluemix http://bluemix.net

The user is asked for permission for the ToDo App to access their profile…

…and once granted, the user now has permission to make the DELETE call; the ToDo item is deleted successfully.

Command Line Interface

Bluemix uses the CloudFoundry command line interface (CLI) – cf

cf help – provides help page showing all the commandscf help <command> - provides help for specific command

cf api api.ng.bluemix.netcf l - login cf ds – delete servicecf t – target space or organisation cf bs – bind service to applicationcf a – list apps in current space cf st – start appcf app - display status for specific app in current space

cf sp – stop app

cf p – push (deploy or update) app cf d – delete appcf s – show service info cf scale – scale appcf cs – create service cf logs – tail or show logs for app

What is Docker?

Light-weight packaged Linux runtimes–Primarily “one” service (can be group of processes)

Based on Linux control-groups (LXC)–Now libContainer

Build images with payload

Run images anywhere – containers–Fast startup and shutdown

Docker Demo: Node.js Personality Insights App

Bluemix offers a Watson Personality Insights Demo application built on Node.js. Here, we “Dockerize” it, by creating our own Docker image with the sample application code provided.

A Dockerfile is used to create a custom image.

Create Dockerfile:

#Start from the official node.js image on DockerhubFROM node:4-onbuild#Set the VCAP_SERVICES environment variable, containing the access credentials for the Watson Personality Insights ServiceENV VCAP_SERVICES="{\"personality_insights\": [{\"name\": \“SNIP…"}}]}“#Open port 3000 into the container for public access to web applicationEXPOSE 3000

Build the image with docker build –t node_personality .

Run a new container from the image with docker run –it –p 3000:3000 –name personality_app node_personality

Docker Demo: Node.js Personality Insights App

The Docker container with the Personality Insights webapp is running on the local machine, while using an instance of the Watson Personality Insights service running in Bluemix.

Bluemix: Support for Containers as a Service (CaaS) with Docker In addition to CloudFoundry apps, Bluemix now provides the

Containers Service.

Allows the deployment of containers running applications and services.

Each user has their own private registry for storing Docker images within his/her Bluemix account.

Interacts with the containers service by using the Bluemix User Interface, or by the Cloud Foundry CLI with the IBM Containers Plugin.

Containers can bind to existing Bluemix services.
