The jdubois/jdubois-codespaces Docker image

This Docker image is based on mcr.microsoft.com/vscode/devcontainers/universal:linux, which is the default Docker image for Codespaces.

• As it's based on the default Codespaces Docker image, it has all the tools and utilities from the default image
• It replaces the default Java 8, OpenJDK-based image with Azul Zulu's Java 11 so we have a more recent and supported JDK
• It adds Docker Compose, as many Java developers use it to run their services

This image is available on DockerHub at jdubois/jdubois-codespaces.

How to use this image

You need to add a .devcontainer/devcontainer.json to your repository:

{
  "name": "jdubois-codespaces",
  "image": "jdubois/jdubois-codespaces",
  "settings": {
    "terminal.integrated.shell.linux": "/bin/bash"
  },
  "forwardPorts": [8080, 9000],
  "extensions": [
    "dbaeumer.vscode-eslint",
    "ms-azuretools.vscode-docker",
    "ms-vscode.azurecli",
    "Pivotal.vscode-boot-dev-pack",
    "Pivotal.vscode-spring-boot",
    "redhat.java",
    "redhat.vscode-yaml",
    "VisualStudioExptTeam.vscodeintellicode",
    "vscjava.vscode-java-debug",
    "vscjava.vscode-java-dependency",
    "vscjava.vscode-java-pack",
    "vscjava.vscode-java-test",
    "vscjava.vscode-maven",
    "vscjava.vscode-spring-boot-dashboard",
    "vscjava.vscode-spring-initializr"
  ]
}

Or if you can download the devcontainer.json provided in this directory:

curl -fsSL https://raw.githubusercontent.com/jdubois/jdubois-codespaces/master/devcontainer.json --output devcontainer.json

This configuration file is made for JHipster projects, for normal Java developers you probably only want to open up port 8080.

It will configure Codespaces with some popular and useful Visual Studio Code extensions, to develop with Java and Docker.

Test with a sample project

The jdubois/jhipster-vs-codespaces is a JHipster project which is configured to use the jdubois/jdubois-codespaces Docker image. The configuration is available in the .devcontainer/devcontainer.json file.
