The document discusses extending the Eclipse Che open source cloud IDE platform to build custom cloud integrated development environments (IDEs). It describes how Che workspaces use Docker containers to provide runtimes and how extensions can be added through plugins. Examples are given of adding new programming language support using the Language Server Protocol and creating a custom "go" stack and notification plugin. Live demos are also presented of using the Che command line interface to set up and manage reproducible developer workspaces defined through JSON configuration files.

13. Che dir: reproducible and portable
developer workspaces
SETUP
- Docker
- Eclipse Che CLI
CLONE
WORK
$ git clone https//github.com/che-samples/web-java-spring-petclinic
$ che dir up

14. Live Demo: Che dir

15. Che dir: reproducible and portable
developer workspaces
# Defines name of the workspace
workspace.name = “happy”
# Define the Docker image to use to power the workspace's runtime
# This must conform to a Che recipe type:
workspace.runtime.image.location="codenvy/alpine_jdk8"
# Defines memory allocated to the workspace's runtime
workspace.ram = 2048
# Commands are processes that users execute in the IDE.
# Commands will appear in the drop down on the tool bar.
workspace.commands[0].name = "my-first-command"
workspace.commands[0].type = "mvn"
workspace.commands[0].commandLine = "mvn clean install -f ${current.project.path}"
workspace.commands[0].attributes.previewUrl = "http://${server.port.8080}/${current.project.relpath}"
# A command that will be executed after the workspace is loaded.
# Reference the name of a command defined above.
workspace.postload.actions[0].name="my-second-command"
