Introduction to Docker

Eclipse Neon Webinar - Docker Tooling - @xcoulon6

Docker components

• Images

• Containers

• Daemons

• Clients

• Registries

Eclipse Neon Webinar - Docker Tooling - @xcoulon7

Docker Images

• "build" components

• read-only templates

• combination of layers

• built using a Dockerfile

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

Docker Daemon

• runs natively on Linux

• inside a VM on Windows and Mac OS X

Eclipse Neon Webinar - Docker Tooling - @xcoulon10

Docker Clients

clients (CLI, IDE) run on host VM

Eclipse Neon Webinar - Docker Tooling - @xcoulon11

Docker Registries

• "distribution" components

• public instances (https://hub.docker.com)

• private instances

Eclipse Neon Webinar - Docker Tooling - @xcoulon12

Benefits of Docker• Lightweight

• Fast

• Portable across environments

• Whole stack in a container

• Sandboxing

• No installation. Just run.

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

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)

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

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

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

Vagrant Tooling

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)

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

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
