The document discusses the creation and distribution of multi-architecture Docker images for both Linux and Windows, presented by software engineer Stefan Scherer. It covers topics such as building CI pipelines, using manifest lists, and demonstrating multi-arch capabilities with Docker images. Additionally, the document provides tips and tricks for managing container deployments across different operating systems and hardware architectures.

5. What is a container?

6. What is a container?
Standardized packaging for
soLware and dependencies
Isolate apps from each other
Share the same OS kernel
Works for all major Linux
distribuPons

7. Containers on all major platforms

8. docker container run
Hub
nginx microsoft/iis

9. docker container run - different OS
Hub
nginx microsoft/iis
⚡ ⚡LCOW FTW!

10. docker container run - different CPU architecture
Hub
nginx
⚡ ⚡
IBM s390
arm32v7/nginx

11. Manifest lists

12. Manifest list
Hub
me/myapp

13. Manifest list: docker container run
Hub
me/myapp me/myappme/myapp

14. Use cases

15. docker run portainer/portainer

16. docker run microsoft/dotnet

17. Many official images are multi-arch now
Windows work in progress…

18. How to build container images?

19. docker image build / docker image push
Hub
me/myapp:linux me/myapp:windows

20. How to build the manifest list?

21. docker manifest command
Pull request https://github.com/docker/cli/pull/138
Docker 17.12 ?
manifest-tool from Phil Estes
Binaries at https://github.com/estesp/manifest-tool/releases
Availability

22. docker manifest create
Hub
me/myapp

23. docker manifest push
Hub
me/myapp

24. Demo
building a multi-arch container image

25. How to build a CI pipeline for that?

26. Docker CI Pipeline for Linux and Windows
docker image push
git push
docker image push
Container
Registry
Run Unit Tests
Build App
docker image build
docker manifest push

27. Hub
Docker CI Pipeline for Linux and Windows
docker image push
git push
docker image push
Run Unit Tests
Build App
docker image build
docker manifest push
Example: github.com/StefanScherer/whoami

28. Tips & Tricks

29. Show the platforms of a Docker Hub image

30. Use Platform constraints in a hybrid Docker Swarm
services:
web:
image: microsoft/iis
deploy:
placement:
constraints:
- node.platform.os == windows

31. Use Platform constraints in a hybrid Docker Swarm
services:
web:
image: nginx
deploy:
placement:
constraints:
- node.platform.os == linux

32. docker manifest command
