- 5. IBM Bluemix is a Cloud Foundry Certified Platforms https://www.cloudfoundry.org/certified-platforms/ 05/09/17 5
- 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 05/09/17 6
- 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". https://en.wikipedia.org/wiki/ChrootChr cgroups 2007 LXC 2008 warden 2011 2012 rocket 2016 Docker, lmctfy 2014 Garden, 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. https://en.wikipedia.org/wiki/LXC 05/09/17 7

- 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 05/09/17 10

- 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. 05/09/17 13
- 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
- 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 05/09/17 20
