Introduction to Docker

EclipseCon Europe 2016- Docker Tooling for Developers - @xcoulon5

Docker components

• Images

• Containers

• Daemons

• Clients

• Registries

EclipseCon Europe 2016- Docker Tooling for Developers - @xcoulon6

Docker Images

• "build" components

• read-only templates

• combination of layers

• built using a Dockerfile

EclipseCon Europe 2016- Docker Tooling for Developers - @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

Docker Daemon

• runs natively on Linux

• inside a VM on Windows and Mac OS X

EclipseCon Europe 2016- Docker Tooling for Developers - @xcoulon9

Docker Clients

clients (CLI, IDE) run on host VM

EclipseCon Europe 2016- Docker Tooling for Developers - @xcoulon10

Docker Registries

• "distribution" components

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

• private instances

Benefits of Docker• Lightweight

• Fast

• Portable across environments

• Whole stack in a container

• Sandboxing

• No installation. Just run.

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

Docker setup

• Install Docker for Windows/Mac/Linux or Docker Toolbox from docker.com or the Red Hat Container Development Kit (CDK) at http://developers.redhat.com/products/cdk

• Install Eclipse Docker tooling

• from Eclipse Marketplace

• from eclipse.org/linuxtools

• as part of Red Hat Developer Studio (http://developers.redhat.com/products/devstudio)

• from tools.jboss.org (mirrors eclipse.org/linuxtools)

EclipseCon Europe 2016- Docker Tooling for Developers - @xcoulon14

Eclipse Mars Release• Docker Explorer view (tree) + Docker Images and Containers

views (list)

• 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

EclipseCon Europe 2016- Docker Tooling for Developers - @xcoulon15

Eclipse Neon Releases• Dockerfile editor (external contribution)

• Support for Docker Compose

• Image Hierarchy view

• Execute shell commands in Terminal view

• Improved support for connections

• Push to registries with authentication

• Bug fixes (thanks to AERI reports)
