DevContainer

A devcontainer (short for "development container", https://containers.dev/) is a pre-configured, isolated environment defined by configuration files (like devcontainer.json and Dockerfiles) that sets up all the tools, dependencies, and settings needed for a project. It allows developers to work in a consistent environment, regardless of their local setup, often using Visual Studio Code's "Remote - Containers" feature (https://code.visualstudio.com/docs/devcontainers/containers). This helps avoid "it works on my machine" issues and simplifies onboarding for new contributors.

Main Features

• Go Development: Includes Go and common Go utilities pre-installed and available on the PATH, along with the Go language extension for enhanced Go development.
• Up-to-date Git: Ships with an up-to-date version of Git, built from source if needed, and available on the PATH.
• Docker CLI: The Docker CLI (docker) and Docker Compose v2 are pre-installed, allowing container management using the host's Docker daemon.
• GitHub CLI: The latest GitHub CLI (gh) is installed and available on the PATH.
• Kubernetes in Docker (KinD): Includes KinD for running local Kubernetes clusters, supporting Kubernetes-native development and testing.
• Enhanced Shell Experience: Zsh is set as the default shell, with Oh My Zsh, Powerlevel10k theme, and a curated set of plugins (e.g., autosuggestions, syntax highlighting, kubectl, docker, git, golang, helm).
• Host Home Directory Mount: Mounts the host's home directory as read-only at /mnt/hosthome for easy access to configuration files and credentials.
• Automatic Powerlevel10k Setup: If a .p10k.zsh config is found in the host's home, it is copied and sourced automatically in the container.
• Automatic Package Upgrades: System packages are upgraded on container creation, including support for non-free packages.
• Network Capabilities: This devcontainer setup allows to carry out networking actions, such as creating Linux network namespaces and new network interfaces.

Behaviours

• On container start, the Powerlevel10k theme is installed and configured if a .p10k.zsh file is present.
• Zsh plugins and Oh My Zsh plugins are installed for the vscode user.
