Deploying a Web App on Azure Container Services

Azure Container instances and Azure container services are an amazing approach to get started with containers very quickly on the Azure cloud services platform.

ACI / ACS lets you concentrate on just your business functions of the codebase while taking care of a lot of the internal wiring and infrastructure so you can get your product or service in front of your customers quickly.

In this short talk we’ll look at taking a sample app on the ACS platform from zero to 100 and cover what is required to build and scale.

1. Deploying a web app On Azure container services
2. Kerala • Old school sys / network admin • <3 shell / UNIX • Cloud • IoT • Mail • DNS
3. Kerala Agenda • Docker – What is it? What give? • Dockerfiles • Azure Container offerings • Azure Container instances • Demo
4. What are containers?
5. Kerala • A Standard unit of software that packages code and all of its dependencies so the application run quickly and reliably from one computing environment to another • Includes everything needed to run the application: code, runtime, system tools and libraries as well as settings. • Multiple containers are run by a single OS kernel, therefore are more lightweight than virtual machines.

8. Why Containers?
9. Kerala Agility • Reduced effort from dev to production • Streamlined dev / test cycles • Faster time to market • Quicker turnaround time
10. Kerala Portability • Write once run everywhere • Standardised environment throughout lifecycle • Immutability brings lesser moving parts • More security - More safety
11. Kerala Scalability • Less overhead on infra • Reduced cycle time - Faster boot up / restarts • Skewed scaling with Orchestration • Ramp down as well as Ramp up
12. Use cases…
13. Kerala • Cloud Native • Lift and Shift • Batch & Bulk Processing • New age tech - IoT / ML / AI
14. Container Services on Azure
15. Kerala • Azure Container Registry (ACR) • Azure Container Instance (ACI) • Azure Web Apps for Containers • Azure Kubernetes Service (AKS)
16. Azure Container Registry
17. Kerala • A repository for storing container images • Similar to public registry like docker hub, but typically used in private model • Container images can be replicated across Azure regions (Premium ACR SKU) • Containers must have a tag corresponding to the name of the ACR
18. Azure Container Instances
19. Kerala • Just, run your containers, job done! • Really quick time to market • Serverless - Worry about business, not infrastructure • Bill for what you use - pay per second • All the Managed Service benefits
20. Dockerfile
21. FROM python:3.7.3-alpine3.8 MAINTAINER mail@cruisemaniac.com RUN apk add --no-cache mariadb-dev build-base ADD requirements.txt / RUN pip install -r /requirements.txt COPY ./ /code WORKDIR /code CMD [ "python", ”app.py" ]
22. Build, Deploy & Demo
