IBM Bluemix is a cloud platform that allows developers to quickly setup and deploy applications. It uses containers and Kubernetes to provide an isolated runtime environment for applications. Developers can use the Bluemix command line interface to interact with the platform, deploying code with a single command. The platform handles configuration, builds applications using buildpacks, and runs them across a scalable container infrastructure.

6. Bluemix is a Container Technology
- Containers, in general, are common technology
- They come in various implementations:
- Docker
- Garden
- ...
- They come with various orchestrators:
- Docker Swarm
- Kubernetes
- Diego
- CF Diego is one path to containers

7. Container History
chroot
1979
A chroot on Unix operating systems is an
operation that changes the apparent root
directory for the current running process
and its children. A program that is run in
such a modified environment cannot name
(and therefore normally cannot access) files
outside the designated directory tree. … The
modified environment is called a "chroot
jail".

runCLXC (Linux Containers) is an operating-
system-level virtualization environment for
running multiple isolated Linux systems
(containers) on a single Linux control host.
…
LXC combines kernel's cgroups and
support for isolated namespaces to
provide an isolated environment for
applications.

9. CLI tool to interact with
Cloud Foundry
Cloud Foundry Command Line Interface tool is the way to interact
with Cloud Foundry.
It’s used to :
•Login to CF
•Deploy application from your Workstation to cloud
•Scale memory for your application
•Scale instances of your application
•Create space to organize environment
•And many other usage...
cf help –a to see all possible command cf CLI can run
05/09/17 9

10. CLI tool installation
http://docs.cloudfoundry.org/cf-cli/install-go-cli.html
Follow the instructions for your Operating System:
You can get instruction from Bluemix when you provision the runtime environment
From Getting Started panel inside the runtime instance:
https://github.com/cloudfoundry/cli#downloads
To verify that cf CLI is correctly installed:
cf --version
CLI is available for all Operating System except Android and iOS

12. cf login
The first step to be performed
is the :
cf login
API endpoint Region
https://api.ng.bluemix.net US South
https://api.eu-gb.bluemix.net United Kingdom
https://api.au-syd.bluemix.net Sydney
Login tells CF which is:
i.your Cloud Foundry provider
ii.your organization
iii.your space
05/09/17 12

13. Space and Organization
Space contains application and services.
Organization groups all spaces together. Organization has
administrative task.
User account consists of username and password:
username are usually email.
Quotas are size constraints for organization and spaces.
used to control cost.

14. Code deployment process
A process made of 3 stages:
BUILD Transforms source code into an executable
RELEASE Combines the executable with the available configuration
RUN Release package is deployed and executed
05/09/17 14

15. What happens with cf push
• cf CLI sends all our files to Cloud Controller
• Cloud Controller finds the right Buildpack
• Files are processed by Buildpack
• Buildpack builds the droplet
• Cloud Foundry stores all files into a Blob store
Manifest.yml
Used to specify parameters necessary to build the application
Manifest guarantees droplet is produced always in the same way
Buildpack functionality :
• detect the programming language of the application
• install dependencies required by the application
• compile the application if necessary
• provide to Cloud Foundry the application configuration data
In detection step, Buildpack looks for particular file or directories
Es. Node.js buildpack looks for file package.json
Build + Release stage
05/09/17 15

16. Buildpack in execution
05/09/17 16

17. Last stage is Run
BUILD and RELEASE complete successfully
Cloud Foundry RUNs your application
When your application is running
Cloud Foundry ensure your application is healthy
Cloud Foundry health monitor constantly checks your application status
• automatically replace crashed container
• email alert for unexpected behaviour
05/09/17 17

18. Logging
Logaggregator
Logaggregator is responsible to manage logging
Logs flow continuosly as long as the application is running
Your application writes to STDERR and STDOUT
A log line contains:
Timestamp: determined by logaggregator when receives data
Log Type: represent origin of log. It’s a 3 letter code: API , STG, RTR, LGR, APP,CELL
API=user api call
APP=application that emits log
CELL= cell logs when it start/stop the app.....
Channel: STDOUT, STDERR
Message: text with log
05/09/17 18

19. Diego
Diego is the hearth of Cloud Foundry architecture.
Applications run in Garden containers inside Diego Cell.
Diego orchestrates application execution and determines in which
Diego cell deploy your application.
Application are divided in two categories:
Single task :
application that is discarded as soon as the task is completed
Long running task:
like web application and worker app
05/09/17 19

20. Cloud Foundry Services
Cloud Foundry services are available on catalog
cf marketplace to view all services available in the catalog
When a new service is provisioned:
Service Broker
takes the request
creates the service instance
when the new service is online, binds service instance to the application
