devcontainers

Description

This repository contains some development container definitions for VSCode Remote Development. Each image is composed by stacking "layers", to make it easier to have different toolchains in a single image.

Usage

Prebuilt images

Look in the release-config.json file to discover what kind of prebuilt images are available. Usage: ghcr.io/murar8/devcontainer-[IMAGE_NAME]:latest

Then in devcontainer.json devcontainer.json:

{
  "image": "ghcr.io/murar8/devcontainer-[IMAGE_NAME]:latest"
}

Build an image locally

Just use scripts/build-push.sh

Individual layer description

common-debian

Only for debian based base images.

• Common command-line utilities and zsh preinstalled.
• Set up with a non-root user named 'vscode'.

Adding a new image definition

Base Image vs Image: TODO

• Create the layer's Dockerfile in containers/[IMAGE NAME]/Dockerfile.

  The image should inherit the base image from previous layers like so:

    ARG BASE_IMAGE
    FROM ${BASE_IMAGE}
  

• Add an entry in release-config.json providing the desired layer composition.

  {
    "name": "golang",
    "from": "golang:1",
    "layers": ["common-debian", "go-debian"]
  }
