docker-devkit

A collection of helper scripts that turn plain Docker installations into a more comfortable development environment on Linux, Windows (WSL2), and macOS.

Highlights

docker-hosts – keeps /etc/hosts in sync with container network aliases so you can skip manual port bindings
docker-alias – bundles a toolbox of Docker-centric commands in one binary with auto-started helpers
lazydocker – brings an approachable TUI for inspecting containers, volumes, and logs
Traefik proxy – optional reverse proxy for easy access to services that expose HTTP endpoints
direnv integration – automatically loads project-specific environment variables when you cd into a directory

Supported Environments

Ubuntu 20.04 / 22.04 LTS (native or in WSL2)
Windows 10 / 11 with WSL2 and Docker Desktop
macOS (experimental; see notes below)

Linux / WSL Ubuntu

Requirements

Docker Engine with your user added to the docker group
Docker Compose (docker compose plugin or standalone docker-compose binary)
curl, unzip, and either bash or zsh

Installation

wget -q -O - "https://raw.githubusercontent.com/clecherbauer/tools/docker-devkit/master/linux/setup.sh" | bash

The script installs the toolchain, ensures daemons are started, and downloads configuration such as /opt/traefik.toml. You may be prompted for sudo when system-level files need to be written.

Updating Re-run the installation command whenever you want to pull the latest versions of the bundled tools. Existing configurations (for example, shell rc files) are only appended to when new entries are required.

Windows (WSL2)

Requirements

Virtualization enabled in BIOS / UEFI
Windows 10 Pro/Enterprise or Windows 11 with the WSL feature available
Administrative PowerShell session for the host setup

Prepare the Windows host

Make sure Windows Update has completed and reboot if required.

Run an elevated PowerShell session and execute:

Set-ExecutionPolicy Bypass -Scope Process -Force; \
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; \
iex ((New-Object System.Net.WebClient).DownloadString('https://gitlab.com/clecherbauer/tools/docker-devkit/-/raw/master/windows/setup_dependencies.ps1'))

This installs WSL2, Docker Desktop, Chocolatey, and the Windows-side docker-hosts integration.

Reboot once the script finishes to ensure WSL and Docker Desktop complete their setup.
Install Ubuntu 20.04 (or later) from the Microsoft Store and make it the default distribution: wsl --setdefault ubuntu.
In Docker Desktop → Settings → Resources → WSL Integration, enable integration for your Ubuntu distribution.

Install inside WSL Ubuntu

Enable metadata support for your mounted Windows drives (avoids permission issues):
```
cat <<'EOT' | sudo tee /etc/wsl.conf >/dev/null
[automount]
options = "metadata"
EOT
```
Exit the WSL session and run wsl --shutdown from Windows PowerShell or Command Prompt, then reopen Ubuntu.

Inside Ubuntu, run the Linux installer:

wget -q -O - "https://raw.githubusercontent.com/clecherbauer/tools/docker-devkit/master/linux/setup.sh" | bash

macOS (experimental)

Basic scripts live under macos/, but automation is still a work in progress. For now:

Install Docker Desktop for Mac.
Ensure curl, wget, and direnv are available (brew install curl wget direnv).
Review and adapt the Linux script or contribute improvements to macos/setup.sh to match your workflow.

Verification

After installation, confirm the tooling works:

docker ps and docker compose version should succeed without sudo.
docker ps --format '{{.Names}}' should list a running docker-hosts container.
which docker-alias should resolve to ~/.local/bin/docker-alias.
lazydocker should start the TUI within the terminal.

Troubleshooting

If Docker commands fail with permission errors, log out and back in (or restart WSL) so the updated group membership takes effect.
Traefik listens on port 80. Stop the traefik-proxy container (docker stop traefik-proxy) if you need that port for something else.
Re-run the setup script with bash -x for verbose output if you need to diagnose installation issues.

Contributing

Issues and pull requests that improve the setup scripts, especially macOS support, are very welcome. Check the linux/, windows/, and macos/ directories for platform-specific logic before submitting changes.
