Docker Tooling for Java EE Developers
The document discusses Docker tooling for Java EE developers. It provides an overview of Docker components like images, containers, daemons and registries. It then describes how the Docker tools project at Eclipse allows managing Docker connections and building/running Docker images from within the Eclipse IDE. A demo is shown of using LiveReload to publish applications from Eclipse to a Docker container.

- 4. @xcoulon#Devoxx #Docker #Eclipse Dockercomponents • Images • Containers • Daemon • Registries • Clients
- 5. @xcoulon#Devoxx #Docker #Eclipse DockerImages • "build" components • read-only templates • combination of layers
- 6. @xcoulon#Devoxx #Docker #Eclipse DockerContainers • "run" components • based on Images • contain application and dependencies but share same kernel • can be started, stopped, paused, deleted • containers are immutable and disposable
- 7. @xcoulon#Devoxx #Docker #Eclipse DockerDaemon • runs natively on Linux • inside aVM on Windows and Mac OS X
- 8. @xcoulon#Devoxx #Docker #Eclipse DockerClients • clients (CLI, IDE) run on hostVM
- 9. @xcoulon#Devoxx #Docker #Eclipse DockerRegistries • "distribution" components • public instances (https://hub.docker.com) • private instances
- 10. @xcoulon#Devoxx #Docker #Eclipse Benefitsof Docker • No need for an hypervisor for each container • many containers perVM • less memory/CPU resources • Density, infrastructure utilization
- 11. @xcoulon#Devoxx #Docker #Eclipse Benefitsof Docker • Package the full stack in a container: • OS, • JVM, • App server • Application with its configuration • Portable across environments • Developer machine • CI / Staging / Production environments • No more "but it works on my machine" argument
- 12. @xcoulon#Devoxx #Docker #Eclipse Dockerat 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. @xcoulon#Devoxx #Docker #Eclipse Dockersetup • Install Docker Toolbox from docker.com • Install Eclipse Docker tooling • from eclipse.org/linuxtools • from tools.jboss.org (mirrors eclipse.org/linuxtools)
