Using this image

Note: A version of this image for newer JDKs is also available!

You can directly reference pre-built versions of Dockerfile by using the image property in .devcontainer/devcontainer.json or updating the FROM statement in your own Dockerfile to one of the following. An example Dockerfile is included in this repository.

  • mcr.microsoft.com/devcontainers/java:8 (or 8-bookworm, 8-bullseye, 8-buster to pin to an OS version)

Refer to this guide for more details.

You can decide how often you want updates by referencing a semantic version of each image. For example:

  • mcr.microsoft.com/devcontainers/java:2-8 (or 2-8-bookworm, 2-8-bullseye to pin to an OS version)
  • mcr.microsoft.com/devcontainers/java:2.0-8 (or 2.0-8-bookworm, 2.0-8-bullseye to pin to an OS version)
  • mcr.microsoft.com/devcontainers/java:2.0.0-8 (or 2.0.0-8-bookworm, 2.0.0-8-bullseye to pin to an OS version)

However, we only do security patching on the latest non-breaking, in support versions of images (e.g. 2-8). You may want to run apt-get update && apt-get upgrade in your Dockerfile if you lock to a more specific version to at least pick up OS security updates.

See history for information on the contents of each version and here for a complete list of available tags.

Alternatively, you can use the contents of .devcontainer to fully customize your container's contents or to build it for a container host architecture not supported by the image.

Installing Maven or Gradle

You can use the Java Feature to install maven and gradle in .devcontainer/devcontainer.json:

{
  "features": {
     "ghcr.io/devcontainers/features/java:1": {
        "version": "none",
        "installGradle": "true",
        "installMaven": "true"
    }
  }
}

Installing Node.js

Given JavaScript front-end web client code written for use in conjunction with a Java back-end often requires the use of Node.js-based utilities to build, this container also includes nvm so that you can easily install Node.js.

Also, you can use a Node Feature to install any version of Node by adding the following to .devcontainer/devcontainer.json:

{
  "features": {
    "ghcr.io/devcontainers/features/node:1": {
      "version": "latest"
    }
  }
}
