Introduction to Docker

5. Eclipse Neon Webinar - Docker Tooling - @xcoulon5
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)
