🎯 How It Works

Development Environment

# 1. Start containers
docker-compose -f .devcontainer/docker-compose_dev.yml up -d

# 2. Admin user automatically created with defaults:
#    Username: admin
#    Password: admin
#    Email: admin@localhost.local

# 3. Credentials saved to:
#    setup_data/admin_credentials.txt

# 4. Login at:
#    http://localhost:8000/admin/

With Custom Credentials

# 1. Create .env file
cp .env.example .env

# 2. Edit credentials
nano .env
# Set: DJANGO_SUPERUSER_USERNAME=myadmin
#      DJANGO_SUPERUSER_PASSWORD=MySecurePass123!

# 3. Start containers
docker-compose -f .devcontainer/docker-compose_dev.yml up -d

# 4. Login with your custom credentials

Production with GitHub Secrets

# 1. Set GitHub Secrets:
#    - DJANGO_SUPERUSER_USERNAME
#    - DJANGO_SUPERUSER_EMAIL
#    - DJANGO_SUPERUSER_PASSWORD

# 2. Deploy (credentials used automatically)
docker-compose up -d

# 3. Admin user created with your secrets

📋 Environment Variables

Required Variables (with defaults)

# Admin username (default: admin)
DJANGO_SUPERUSER_USERNAME=admin

# Admin email (default: admin@localhost.local)
DJANGO_SUPERUSER_EMAIL=admin@localhost.local

# Admin password (default: admin)
DJANGO_SUPERUSER_PASSWORD=admin

# Credentials file path (default: setup_data/admin_credentials.txt)
ADMIN_CREDENTIALS_FILE=setup_data/admin_credentials.txt

Setting in .env File

# Copy template
cp .env.example .env

# Edit with your values
nano .env

Setting in GitHub Secrets

  1. Go to: Repository → Settings → Secrets → Actions
  2. Add secrets:
  3. DJANGO_SUPERUSER_USERNAME
  4. DJANGO_SUPERUSER_EMAIL
  5. DJANGO_SUPERUSER_PASSWORD

Setting in Azure Key Vault

az keyvault secret set --vault-name mykeyvault \
  --name django-admin-username --value "prodadmin"

az keyvault secret set --vault-name mykeyvault \
  --name django-admin-password --value "$(openssl rand -base64 32)"

🚀 Quick Start Examples

Example 1: Development (Default Credentials)

docker-compose -f .devcontainer/docker-compose_dev.yml up -d
cat setup_data/admin_credentials.txt
open http://localhost:8000/admin/
# Login: admin / admin

Example 2: Development (Custom Credentials)

cat > .env << EOF
DJANGO_SUPERUSER_USERNAME=devadmin
DJANGO_SUPERUSER_PASSWORD=DevPass123!
EOF

docker-compose -f .devcontainer/docker-compose_dev.yml up -d
cat setup_data/admin_credentials.txt
open http://localhost:8000/admin/
# Login: devadmin / DevPass123!

Example 3: Production (GitHub Secrets)

# Set secrets in GitHub (one time)
# Then deploy:
docker-compose up -d
# Admin created with your GitHub secrets

🔒 Security Notes

Development ✅

  • Default credentials (admin/admin) are acceptable
  • Credentials file is gitignored
  • Easy to change via .env

Production ⚠️

  • NEVER use default credentials
  • Use environment variables or secrets management
  • Delete credentials file after first login
  • Use HTTPS only
  • Enable MFA/2FA when available
  • Rotate credentials regularly

🧪 Testing

Test Default Credentials

# Clean start
docker-compose -f .devcontainer/docker-compose_dev.yml down -v
docker-compose -f .devcontainer/docker-compose_dev.yml up -d

# Check logs
docker-compose -f .devcontainer/docker-compose_dev.yml logs python | grep ensure_admin

# Should see:
# ✅ Created admin superuser: admin
# ⚠️  WARNING: Using default credentials

# View credentials
cat setup_data/admin_credentials.txt

# Test login
open http://localhost:8000/admin/

Test Custom Credentials

# Create .env with custom credentials
echo "DJANGO_SUPERUSER_USERNAME=testadmin" > .env
echo "DJANGO_SUPERUSER_PASSWORD=TestPass123!" >> .env

# Clean start
docker-compose -f .devcontainer/docker-compose_dev.yml down -v
docker-compose -f .devcontainer/docker-compose_dev.yml up -d

# Check logs
docker-compose -f .devcontainer/docker-compose_dev.yml logs python | grep ensure_admin

# Should see:
# ✅ Created admin superuser: testadmin

# Test login with custom credentials
open http://localhost:8000/admin/

Test Manual Command

docker-compose -f .devcontainer/docker-compose_dev.yml exec python \
  python manage.py ensure_admin --help

docker-compose -f .devcontainer/docker-compose_dev.yml exec python \
  python manage.py ensure_admin

🛠️ Troubleshooting

Can't find credentials?

# Check if file exists
ls -la setup_data/admin_credentials.txt

# View contents
cat setup_data/admin_credentials.txt

# Or from container
docker-compose exec python cat /workspace/setup_data/admin_credentials.txt

Can't login?

# Check environment variables
docker-compose exec python env | grep DJANGO_SUPERUSER

# Check what was created
cat setup_data/admin_credentials.txt

# Reset password
docker-compose exec python python manage.py changepassword admin

Admin user not created?

# Check logs
docker-compose logs python | grep ensure_admin

# Manually run command
docker-compose exec python python manage.py ensure_admin

📊 What Changed

Before This Implementation

# Manual process every time:
docker-compose up -d
docker-compose exec web-prod python manage.py createsuperuser
# Enter username: admin
# Enter email: admin@example.com
# Enter password: ********
# Confirm password: ********
# Write down credentials somewhere

After This Implementation

# Automatic process:
docker-compose up -d
# Admin created automatically
# Credentials saved to setup_data/admin_credentials.txt
# Just login and go!
