⚠️ Check: The Microsoft devcontainer base image includes many pre-installed tools that the vanilla Ubuntu image does not:

Pre-installed in devcontainer base (now missing):

  • git, sudo, wget, vim, less, jq, openssh-client
  • Non-root vscode user with passwordless sudo
  • Common shell utilities and development tools

Action required: If your workflow depends on any of these tools, add them explicitly to the Dockerfile. For example:

RUN apt-get update && apt-get install -y git sudo vim && rm -rf /var/lib/apt/lists/*

# Standardized to approved base image (ubuntu:22.04 instead of ubuntu-24.04 devcontainer base)
FROM ubuntu:22.04

ℹ️ Info: Updated from mcr.microsoft.com/devcontainers/base:ubuntu-24.04 to ubuntu:22.04.

Key differences:

  • The Microsoft devcontainer base includes pre-installed tools (git, sudo, common utilities) and a non-root user setup
  • The official ubuntu:22.04 is a minimal base that requires explicit installation of these tools
  • Ubuntu 24.04 → 22.04 is a downgrade to the LTS version for stability

Why this works:

  • Both are Debian-based (apt package manager compatibility)
  • The Dockerfile already installs all required tools explicitly
  • No reliance on devcontainer-specific features


# use this Dockerfile to install additional tools you might need, e.g.
# RUN apt-get update && export DEBIAN_FRONTEND=noninteractive \
