WSL Administration

Requires: WSL2 context, Ubuntu 24.04

⚠️ Critical: Profile Location

The profile lives on the WINDOWS side, not in WSL home.

# WRONG - this doesn't exist in WSL
ls ~/.admin/profiles/  # Empty!

# RIGHT - profile is on Windows, accessed via /mnt/c
WIN_USER=$(cmd.exe /c "echo %USERNAME%" 2>/dev/null | tr -d '\r')
ADMIN_ROOT="/mnt/c/Users/$WIN_USER/.admin"
PROFILE_PATH="$ADMIN_ROOT/profiles/$(hostname).json"
ls "$PROFILE_PATH"  # Found!

Quick Start

The loader auto-detects WSL and uses the correct path:

source /path/to/admin/scripts/load-profile.sh
show_environment  # Verify detection
load_admin_profile
show_admin_summary

Output should show:

Type:        WSL (Windows Subsystem for Linux)
Win User:    {your-windows-username}
ADMIN_ROOT:  /mnt/c/Users/{username}/.admin
Profile:     /mnt/c/Users/{username}/.admin/profiles/{hostname}.json
Exists:      YES

Check WSL Config from Profile

# Profile has WSL section
jq '.wsl' "$PROFILE_PATH"

# Resource limits
jq '.wsl.resourceLimits' "$PROFILE_PATH"
# Returns: {"memory": "16GB", "processors": 8, "swap": "4GB"}

# WSL tools
jq '.wsl.distributions["Ubuntu-24.04"].tools' "$PROFILE_PATH"

Package Installation (Profile-Aware)

Python - Check Preference

PY_MGR=$(jq -r '.preferences.python.manager' "$PROFILE_PATH")
# Returns: "uv" or "pip" or "conda"

case "$PY_MGR" in
    uv)     uv pip install "$package" ;;
    pip)    pip install "$package" ;;
    conda)  conda install "$package" ;;
esac

Node - Check Preference

NODE_MGR=$(jq -r '.preferences.node.manager' "$PROFILE_PATH")

case "$NODE_MGR" in
    npm)    npm install "$package" ;;
    pnpm)   pnpm add "$package" ;;
    yarn)   yarn add "$package" ;;
    bun)    bun add "$package" ;;
esac

System Packages (apt)

sudo apt update
sudo apt install -y $package

Docker Operations

Check Docker from Profile

DOCKER_PRESENT=$(jq -r '.docker.present' "$PROFILE_PATH")
DOCKER_BACKEND=$(jq -r '.docker.backend' "$PROFILE_PATH")

if [[ "$DOCKER_PRESENT" == "true" && "$DOCKER_BACKEND" == "WSL2" ]]; then
    # Docker Desktop with WSL2 integration
    docker ps
fi

Common Commands

docker ps                    # List running
docker images               # List images
docker logs <container>     # View logs
docker exec -it <c> bash    # Shell into container
docker-compose up -d        # Start compose stack

Path Conversions

Windows paths in profile need conversion:

# Profile path: "C:/Users/Owner/.ssh"
# WSL path:     "/mnt/c/Users/Owner/.ssh"

win_to_wsl() {
    local win_path="$1"
    local drive=$(echo "$win_path" | cut -c1 | tr '[:upper:]' '[:lower:]')
    local rest=$(echo "$win_path" | cut -c3- | sed 's|\\|/|g')
    echo "/mnt/$drive$rest"
}

# Usage
SSH_PATH=$(jq -r '.paths.sshKeys' "$PROFILE_PATH")
WSL_SSH_PATH=$(win_to_wsl "$SSH_PATH")

SSH to Servers

Use profile server data:

# Get server info
SERVER=$(jq '.servers[] | select(.id == "cool-two")' "$PROFILE_PATH")
HOST=$(echo "$SERVER" | jq -r '.host')
USER=$(echo "$SERVER" | jq -r '.username')
KEY=$(echo "$SERVER" | jq -r '.keyPath')

# Convert Windows key path
WSL_KEY=$(win_to_wsl "$KEY")

# Connect
ssh -i "$WSL_KEY" "$USER@$HOST"

Or use the loader helper:

source load-profile.sh
load_admin_profile
ssh_to_server "cool-two"  # Auto-converts paths

Update Profile from WSL

After installing a tool in WSL:

# Read profile
PROFILE=$(cat "$PROFILE_PATH")

# Update WSL tools section
PROFILE=$(echo "$PROFILE" | jq --arg ver "$(node --version)" \
    '.wsl.distributions["Ubuntu-24.04"].tools.node.version = $ver')

# Save
echo "$PROFILE" | jq . > "$PROFILE_PATH"

Resource Limits

Controlled by

.wslconfig

jq '.wsl.resourceLimits' "$PROFILE_PATH"

To change, hand off to

admin-windows

# Log handoff
echo "[$(date -Iseconds)] HANDOFF: Need .wslconfig change - increase memory to 24GB" \
    >> "$ADMIN_ROOT/logs/handoffs.log"

Capabilities Check

# From profile
HAS_DOCKER=$(jq -r '.capabilities.hasDocker' "$PROFILE_PATH")
HAS_GIT=$(jq -r '.capabilities.hasGit' "$PROFILE_PATH")

if [[ "$HAS_DOCKER" == "true" ]]; then
    docker info
fi

Issues Tracking

Check known issues before troubleshooting:

jq '.issues.current[]' "$PROFILE_PATH"

Add new issue:

PROFILE=$(cat "$PROFILE_PATH")
PROFILE=$(echo "$PROFILE" | jq '.issues.current += [{
    "id": "wsl-docker-'"$(date +%s)"'",
    "tool": "docker",
    "issue": "Docker socket not found",
    "priority": "high",
    "status": "pending",
    "created": "'"$(date -Iseconds)"'"
}]')
echo "$PROFILE" | jq . > "$PROFILE_PATH"

Common Tasks

Update System

sudo apt update && sudo apt upgrade -y

Install Python Package (Profile-Aware)

PY_MGR=$(get_preferred_manager python)
case "$PY_MGR" in
    uv)  uv pip install requests ;;
    *)   pip install requests ;;
esac

Create Python Venv

PY_MGR=$(get_preferred_manager python)
if [[ "$PY_MGR" == "uv" ]]; then
    uv venv .venv
    source .venv/bin/activate
    uv pip install -r requirements.txt
else
    python -m venv .venv
    source .venv/bin/activate
    pip install -r requirements.txt
fi
