The document discusses Docker tooling available in Eclipse. It begins with an introduction to Docker components like images, containers, daemons and registries. It then outlines the Docker support in Eclipse, including managing connections, searching/pulling images, building/running images, and managing containers. The presentation concludes with a demo of these features and plans to support Docker Compose and other improvements in upcoming Eclipse releases.

Docker components
• Images
• Containers
• Daemons
• Clients
• Registries

6. Eclipse Neon Webinar - Docker Tooling - @xcoulon6
Docker Images
• "build" components
• read-only templates
• combination of layers
• built using a Dockerfile

7. Eclipse Neon Webinar - Docker Tooling - @xcoulon7
Docker Containers
• "run" components
• based on Images
• contain application and dependencies but share same kernel
• can be started, stopped, paused, deleted
• can be linked to other containers
• containers are immutable and disposable

8. Eclipse Neon Webinar - Docker Tooling - @xcoulon8
Docker Daemon
• runs natively on Linux
• inside a VM on Windows and Mac OS X

9. Eclipse Neon Webinar - Docker Tooling - @xcoulon9
Docker Clients
clients (CLI, IDE) run on host VM

10. Eclipse Neon Webinar - Docker Tooling - @xcoulon10
Docker Registries
• "distribution" components
• public instances (https://hub.docker.com)
• private instances

11. Eclipse Neon Webinar - Docker Tooling - @xcoulon11
Benefits of Docker
• Lightweight
• Fast
• Portable across environments
• Whole stack in a container
• Sandboxing
• No installation. Just run.

12. Eclipse Neon Webinar - Docker Tooling - @xcoulon12
Docker at eclipse.org
• Linux tools project (works on Mac OS X and Windows,
too)
• Make Docker accessible from Eclipse
• Works with existing Docker tools (docker-machine, etc.)
• Focus on developer experience
• Allow reuse by other plugins

13. Eclipse Neon Webinar - Docker Tooling - @xcoulon13
Docker setup
• Install Docker for Windows/Mac/Linux or Docker
Toolbox from docker.com
• Install Eclipse Docker tooling
• from eclipse.org/linuxtools
• from tools.jboss.org (mirrors eclipse.org/linuxtools)

14. Eclipse Neon Webinar - Docker Tooling - @xcoulon14
Eclipse Mars Release
• Docker Explorer view (tree view) + Docker Images and
Containers view (list views)
• Search pull and push images on Docker Hub
• Run images (wizard and launcher)
• Build images (wizard and launcher)
• Manage containers (start/stop/pause/unpause/kill/remove/
tag)
• Display container logs

15. Eclipse Neon Webinar - Docker Tooling - @xcoulon15
Eclipse Neon Release
• Dockerfile editor (external contribution)
• Execute shell commands in Terminal view
• Improved support for connections
• Push to registries with authentication
• Bug fixes (thanks to AERI reports)
