This document is a presentation from the Eclipse Democamp Munich 2016 by Xavier Coualon on Docker and Vagrant tooling for developers. It covers an introduction to Docker, including components such as images, containers, and registries, as well as Docker tooling in Eclipse and upcoming features. Additionally, it briefly discusses Vagrant tooling, its components, and highlights the benefits of both technologies for developers.

Introduction to Docker

6. Eclipse Neon Webinar - Docker Tooling - @xcoulon6
Docker components
• Images
• Containers
• Daemons
• Clients
• Registries

7. Eclipse Neon Webinar - Docker Tooling - @xcoulon7
Docker Images
• "build" components
• read-only templates
• combination of layers
• built using a Dockerfile

8. Eclipse Neon Webinar - Docker Tooling - @xcoulon8
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

9. Eclipse Neon Webinar - Docker Tooling - @xcoulon9
Docker Daemon
• runs natively on Linux
• inside a VM on Windows and Mac OS X

10. Eclipse Neon Webinar - Docker Tooling - @xcoulon10
Docker Clients
clients (CLI, IDE) run on host VM

11. Eclipse Neon Webinar - Docker Tooling - @xcoulon11
Docker Registries
• "distribution" components
• public instances (https://hub.docker.com)
• private instances

12. Eclipse Neon Webinar - Docker Tooling - @xcoulon12
Benefits of Docker
• Lightweight
• Fast
• Portable across environments
• Whole stack in a container
• Sandboxing
• No installation. Just run.

13. Eclipse Neon Webinar - Docker Tooling - @xcoulon13
Docker tooling 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

14. Eclipse Neon Webinar - Docker Tooling - @xcoulon14
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)

15. Eclipse Neon Webinar - Docker Tooling - @xcoulon15
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

16. Eclipse Neon Webinar - Docker Tooling - @xcoulon16
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)

Summary of highlighted Docker features
• Manage connection to Docker daemons
• Search and pull images
• Build custom images from Dockerfile
• Run images with specific ports, volumes and links to containers
• Manage containers (start/stop/pause/unpause/kill)
• Use a server adapter
• Remote debug in a container

21. Eclipse Neon Webinar - Docker Tooling - @xcoulon21
Plans for Eclipse Oxygen
• Support for Docker Compose
• Image Hierarchy view
• Import/export "docker run" commands
• Server Adapter (JBoss Tools)
• Improved registry accounts management

22. INSERT DESIGNATOR, IF NEEDED (EDIT ON MASTER SLIDE)22
Vagrant Tooling

23. Eclipse Neon Webinar - Docker Tooling - @xcoulon23
Vagrant Overview
• Boxes: package format for Vagrant environment
• Vagrantfile: specification to run the VM
• VM: lifecycle (start, stop, destroy, ssh, package)

24. Eclipse Neon Webinar - Docker Tooling - @xcoulon24
Vagrant tooling at eclipse.org
• Linux tools project (works on Mac OS X and
Windows, too)
• Make Vagrant accessible from Eclipse
• Focus on developer experience
• Allow reuse by other plugins

25. Eclipse Neon Webinar - Docker Tooling - @xcoulon25
Vagrant tooling at eclipse.org
• Hypervisor: software that manages virtual machines
(VirtualBox, KVM, Xen, etc.)
• Vagrant:
• a layer of abstraction above the hypervisor
• uniform way to manage virtual environments
