Getting Started with DDEV Coder Workspaces

This guide helps you create your first DDEV workspace and start developing in the cloud.

What is Coder?

Coder is an open-source platform for creating remote development environments. Instead of developing on your local machine, you work in a cloud-based workspace with all tools pre-installed.

Key concepts:

• Workspace - Your personal development environment (like a remote VM)
• Template - A blueprint for creating workspaces (pre-configured tools, settings)
• Agent - Software running in your workspace that connects to Coder server

What is DDEV?

DDEV is a local development tool for PHP, Node.js, and Python projects. It uses Docker containers to provide consistent development environments with databases, web servers, and development tools.

With this template, DDEV runs inside your cloud workspace, giving you all DDEV features without local setup.

Prerequisites

Coder Account

You need access to a Coder server. Ask your administrator for:

• Coder server URL (e.g., https://coder.example.com)
• Username and password (or SSO login)
• Confirmation that the user-defined-web template is available

Local Tools

Install on your local machine:

Coder CLI (required for SSH access):

# macOS (Homebrew)
brew install coder/coder/coder

# Linux (curl)
curl -L https://coder.com/install.sh | sh

# Windows (PowerShell)
winget install Coder.Coder

# Or download from: https://github.com/coder/coder/releases

SSH client (usually pre-installed):

# Verify SSH is available
ssh -V

Git (optional, for cloning repositories):

# macOS
brew install git

# Linux
apt-get install git  # or yum install git

# Windows
winget install Git.Git

# Verify
git --version

Optional: Desktop VS Code

If you prefer desktop VS Code over the web version:

# Download from https://code.visualstudio.com/
# Install Remote-SSH extension
code --install-extension ms-vscode-remote.remote-ssh

Step 1: Login to Coder

Via Web UI

1. Open your Coder server URL in a browser
2. Enter your username and password
3. Click Login

You’ll see the Coder dashboard.

Via CLI

# Login to Coder server
coder login https://coder.example.com

# Enter your credentials when prompted
# Or use an API token if provided

Verify login:

coder list
# Should show your workspaces (empty if this is your first time)

Step 2: Create Your First Workspace

Via Web UI

1. Click Create Workspace button
2. Select user-defined-web template
3. Enter a workspace name (e.g., my-first-workspace)
   • Use lowercase, numbers, hyphens
   • No spaces or special characters
4. (Optional) Configure parameters:
   • CPU: Number of cores (default: 4)
   • Memory: RAM in GB (default: 8)
   • Node.js version: Node version (default: 24)
5. Click Create Workspace

Wait for workspace to start (1-3 minutes):

• Status will change from “Starting” to “Running”
• You’ll see the workspace dashboard

Via CLI

# Create workspace with defaults
coder create --template user-defined-web my-first-workspace --yes

# Or with custom parameters
coder create --template user-defined-web my-first-workspace \
  --parameter cpu=8 \
  --parameter memory=16 \
  --yes

Check workspace status:

coder list
# Should show your workspace as "Running"

Step 3: Access Your Workspace

Option 1: VS Code for Web (Recommended for Beginners)

1. In Coder dashboard, find your workspace
2. Under Apps, click VS Code
3. VS Code opens in your browser

You now have a full IDE in the cloud!

Option 2: SSH (Command Line)

# SSH into workspace
coder ssh my-first-workspace

# You're now inside your workspace
# The prompt changes to: coder@my-first-workspace:~$

Run your first command:

# Check DDEV is installed
ddev version

# Check Docker is running
docker ps

# Check Node.js version
node --version

# Exit SSH session
exit

Option 3: Desktop VS Code with Remote-SSH

# Configure SSH for Coder workspaces
coder config-ssh

# Open desktop VS Code
# Use Remote-SSH extension to connect to: coder.my-first-workspace

Step 4: Verify Your Environment

Check Docker

# Inside workspace (via SSH or VS Code terminal)
docker ps
# Should show: CONTAINER ID   IMAGE   COMMAND   ...
# (Empty list is normal - no containers running yet)

docker info
# Should show Docker system information

If Docker doesn’t work, see Troubleshooting below.

Check DDEV

ddev version
# Should show DDEV version (latest version from image)

ddev list
# Should show: No running DDEV projects were found.

Check Disk Space

df -h
# Should show plenty of free space on / and /home/coder

Check Available Resources

# CPU cores
nproc

# RAM
free -h

# Should match what you configured (default: 4 cores, 8GB RAM)

Step 5: Create Your First DDEV Project

Option A: New Project from Scratch

# Create project directory
mkdir -p ~/projects/my-site
cd ~/projects/my-site

# Initialize DDEV project
# Choose a project type: php, wordpress, drupal, laravel, etc.
ddev config --project-type=php --docroot=web

# Start DDEV
ddev start

Wait for DDEV to start (1-2 minutes first time):

Starting my-site...
...
Successfully started my-site
Project can be reached at https://my-site.ddev.site

Option B: Clone Existing Project

# Set up Git SSH first (see Step 8 below)

# Clone your repository
cd ~/projects
git clone git@github.com:username/repo.git my-site
cd my-site

# Configure DDEV (if not already configured)
ddev config --auto

# Start DDEV
ddev start

Option C: Quick Demo with Composer Project

# Create a Laravel project
mkdir -p ~/projects/demo-laravel
cd ~/projects/demo-laravel

# Configure DDEV
ddev config --project-type=laravel --docroot=public

# Use DDEV's Composer to create Laravel project
ddev composer create laravel/laravel

# Start DDEV
ddev start

Step 6: Access Your DDEV Project

Understanding Coder Port Forwarding

DDEV normally uses URLs like https://my-site.ddev.site, but in Coder, you access projects via port forwarding.

How it works:

1. DDEV listens on ports 80/443 inside workspace
2. Coder forwards these ports through its proxy
3. You access via Coder’s forwarded URLs

Access Your Project

Via Coder Web UI (Recommended):

1. Go to Coder dashboard
2. Find your workspace
3. Under Apps, click DDEV Web
4. Your DDEV project loads in a new tab

The URL follows the pattern: https://ddev-web--workspace-name--owner.coder.example.com/

Via CLI Port Forward:

# Forward port to your local machine
coder port-forward my-first-workspace --tcp 8080:80

# Then access in your browser:
# http://localhost:8080

Check DDEV status:

ddev describe
# Shows project details and status
# Note: URLs shown by ddev describe won't work - use Coder's forwarded URLs instead

Step 7: Make Changes and Test

Edit Files

Via VS Code for Web:

1. Open VS Code (Apps → VS Code in Coder UI)
2. Navigate to ~/projects/my-site
3. Edit files normally
4. Changes are saved automatically

Via SSH and vim:

coder ssh my-first-workspace
cd ~/projects/my-site
vim web/index.php

Reload and Test

# Refresh your browser to see changes
# Or use DDEV commands:

ddev describe    # Show project info
ddev logs        # View container logs
ddev exec <cmd>  # Run command in web container

Common DDEV Commands

# Start project
ddev start

# Stop project
ddev stop

# Restart project
ddev restart

# View status
ddev describe

# View logs
ddev logs

# SSH into web container
ddev ssh

# Run Composer
ddev composer install

# Run npm
ddev npm install
ddev npm run dev

# Import database
ddev import-db --file=dump.sql.gz

# Export database
ddev export-db --file=dump.sql.gz

# View all commands
ddev help

Step 8: Working with Git

Configure Git

# Inside workspace
git config --global user.name "Your Name"
git config --global user.email "your.email@example.com"

Set Up Git SSH for Private Repositories

To clone private repositories or push to GitHub/GitLab/etc, you need to add your Coder public key to your Git host.

Step 1: Get your Coder public key

# Inside workspace (via SSH or VS Code terminal)
coder publickey

# This shows your Coder-managed public key
# Copy the entire output (starts with ssh-ed25519 or ssh-rsa)

Step 2: Add key to your Git host

For GitHub:

1. Go to https://github.com/settings/keys
2. Click New SSH key
3. Paste your Coder public key
4. Click Add SSH key

For GitLab:

1. Go to https://gitlab.com/-/profile/keys
2. Paste your Coder public key
3. Click Add key

For Bitbucket:

1. Go to https://bitbucket.org/account/settings/ssh-keys/
2. Click Add key
3. Paste your Coder public key

Step 3: Test SSH connection

# Test GitHub
ssh -T git@github.com
# Should say: "Hi username! You've successfully authenticated..."

# Test GitLab
ssh -T git@gitlab.com
# Should say: "Welcome to GitLab, @username!"

Clone and Push

# Clone private repository
cd ~/projects
git clone git@github.com:username/private-repo.git

# Make changes
cd private-repo
# ... edit files ...

# Commit and push
git add .
git commit -m "Update from Coder workspace"
git push

How it works: Coder’s GitSSH wrapper automatically uses your Coder-managed SSH key for all Git operations. You don’t need to manage SSH keys inside the workspace.

Managing Your Workspace

Stop Workspace (Save Costs)

When not actively developing:

# Via CLI
coder stop my-first-workspace

# Via UI: Click "Stop" button on workspace

What happens when stopped:

• Workspace container stops
• All files in /home/coder are preserved
• DDEV projects are preserved
• Billing/resource usage stops

Start Workspace

# Via CLI
coder start my-first-workspace

# Via UI: Click "Start" button on workspace

Startup time: about a minute (faster than initial create without cache)

After starting:

# SSH in
coder ssh my-first-workspace

# Restart DDEV projects
cd ~/projects/my-site
ddev start

Delete Workspace (Permanent)

⚠️ Warning: This deletes all data permanently!

# Via CLI
coder delete my-first-workspace

# Via UI: Click "Delete" button, confirm

What gets deleted:

• Workspace container
• All files in /home/coder
• All DDEV projects and databases
• Docker images and volumes inside workspace

Before deleting:

# Backup important data
cd ~/projects
tar -czf backup.tar.gz my-site/
# Download via VS Code or scp

Troubleshooting

Workspace Won’t Start

Check status:

coder list
# If stuck in "Starting", check logs:
coder logs my-first-workspace

Common causes:

• Template not deployed correctly (contact admin)
• Resource limits exceeded (contact admin)
• Sysbox runtime not installed on host (contact admin)

Docker Not Working

Symptom: Cannot connect to Docker daemon

Solution:

# Check Docker service
systemctl status docker

# Restart Docker
sudo systemctl restart docker

# Wait a few seconds, then test
docker ps

If still broken, restart workspace: coder restart my-first-workspace

DDEV Won’t Start

Symptom: ddev start fails

Check Docker first:

docker ps
# If this fails, fix Docker before DDEV

Common DDEV issues:

# Reset DDEV project
ddev poweroff
ddev start

# Or delete and recreate
ddev delete --omit-snapshot
ddev config --auto
ddev start

Can’t Access DDEV Project

Symptom: Port forwarding shows ports but URLs don’t load

Check:

# Inside workspace
ddev describe
curl localhost:80
# Should return HTML

Solution:

• Use Coder’s port forwarding links (not DDEV URLs)
• Find port URLs in the Ports section of Coder web UI
• DDEV’s URLs (*.ddev.site) won’t work in Coder

Git SSH Not Working

Symptom: Permission denied (publickey) when cloning

Solution:

1. Get your Coder public key: coder publickey
2. Add that key to GitHub/GitLab (Settings → SSH Keys)
3. Test: ssh -T git@github.com
4. If still failing, regenerate: coder publickey --reset and add new key to Git host

Out of Disk Space

Symptom: No space left on device

Solution:

# Clean Docker images and volumes
docker system prune -a --volumes -f

# Check disk usage
df -h
du -sh ~/projects/*

# Delete unused projects
rm -rf ~/projects/old-project

Workspace is Slow

Check resources:

# Inside workspace
top        # Check CPU usage
free -h    # Check RAM usage
docker stats  # Check Docker container resources

Solution:

• Stop unused DDEV projects: ddev stop --all
• Increase workspace resources (delete and recreate with higher CPU/RAM)
• Contact admin to increase default resources

Tips and Best Practices

File Organization

~/projects/              # All DDEV projects here
  ├── project1/
  ├── project2/
  └── project3/
~/.ddev/                 # DDEV global config (auto-created)
~/.ssh/                  # SSH keys (managed by Coder)

Resource Management

• Stop workspaces when not in use (saves costs)
• Stop unused DDEV projects: ddev stop --all
• Clean Docker regularly: docker system prune -a

Backup Important Data

• Commit to Git regularly (safest backup)
• Export databases: ddev export-db --file=backup.sql.gz
• Download files via VS Code or coder scp

Performance

• Use smaller workspaces for simple projects (2 CPU, 4GB RAM)
• Increase resources for large projects (8 CPU, 16GB RAM)
• Stop background services when not needed
