Single Server Example (nginx-proxy + acme-companion)

This guide demonstrates a single-server setup using nginx-proxy and acme-companion for HTTPS. It is best for a small number of hostnames and a single bench. If you need multiple benches or advanced routing, use the Traefik-based example instead.

We will setup the following:

• Install Docker and Docker Compose v2 on a Linux server.
• Use nginx-proxy + acme-companion for HTTPS (Let's Encrypt).
• Install MariaDB and Redis via containers.
• Setup one project called erpnext with sites erp.your-domain.com and crm.your-domain.com.

Requirements

• A server that can run Docker (recommended: 2 vCPU, 4 GB RAM, 50 GB SSD).
• A public domain with DNS control.
• Two subdomains pointing to your server IP (A/AAAA records):
  • erp.your-domain.com
  • crm.your-domain.com
• Ports 80 and 443 reachable from the internet (required for Let's Encrypt HTTP-01).

Install Docker

Docker can be installed on a variety of systems. The easiest way to do this is with the convenience script.

Platform	Convenience script	Using repository
CentOS	Link	Link
Debian	Link	Link
Ubuntu	Link	Link
Fedora	Link	Link

Then do the post-installation steps. This will ensure that the permissions are easier to use and that Docker will start up with the System. Post-Installation Steps

Prepare

Clone frappe_docker and change the current working directory to the repo.

git clone https://github.com/frappe/frappe_docker
cd frappe_docker

Create a configuration directory:

mkdir ~/gitops

Optional: Build a custom image

If you need extra apps (beyond Frappe/ERPNext), build a custom image. Otherwise, skip this section and use the default images.

Create apps.json (each entry is a Git repo + branch):

cat > ~/gitops/apps.json <<'EOF'
[
  {
    "url": "https://github.com/frappe/erpnext",
    "branch": "version-16"
  },
  {
    "url": "https://github.com/frappe/payments",
    "branch": "version-16"
  }
]
EOF

Example for CRM only:

cat > ~/gitops/apps.json <<'EOF'
[
  {
    "url": "https://github.com/frappe/crm",
    "branch": "main"
  }
]
EOF

Generate the BASE64 value and build:

export APPS_JSON_BASE64=$(base64 -w 0 ~/gitops/apps.json)

docker build \
  --build-arg=FRAPPE_PATH=https://github.com/frappe/frappe \
  --build-arg=FRAPPE_BRANCH=version-16 \
  --build-arg=APPS_JSON_BASE64=$APPS_JSON_BASE64 \
  --tag=my-erpnext-prod-image:16.0.0 \
  --file=images/layered/Containerfile .

If base64 -w 0 is not available on your system, use:

export APPS_JSON_BASE64=$(base64 ~/gitops/apps.json | tr -d '\n')

Configure environment

Create an environment file for the bench:

cp example.env ~/gitops/erpnext.env
sed -i 's/DB_PASSWORD=123/DB_PASSWORD=changeit/g' ~/gitops/erpnext.env
echo 'NGINX_PROXY_HOSTS=erp.your-domain.com,crm.your-domain.com' >> ~/gitops/erpnext.env
echo 'LETSENCRYPT_EMAIL=admin@your-domain.com' >> ~/gitops/erpnext.env

Notes:

• Replace changeit with a strong password.
• Replace domains and email with your production values.
• NGINX_PROXY_HOSTS is a comma-separated list without spaces.
• If you built a custom image, add:

echo "CUSTOM_IMAGE=my-erpnext-prod-image" >> ~/gitops/erpnext.env
echo "CUSTOM_TAG=16.0.0" >> ~/gitops/erpnext.env

Generate compose config

Create the rendered compose file:

docker compose --project-name erpnext \
  --env-file ~/gitops/erpnext.env \
  -f compose.yaml \
  -f overrides/compose.mariadb.yaml \
  -f overrides/compose.redis.yaml \
  -f overrides/compose.nginxproxy.yaml \
  -f overrides/compose.nginxproxy-ssl.yaml config > ~/gitops/erpnext.yaml

Start the stack:

docker compose --project-name erpnext -f ~/gitops/erpnext.yaml up -d

This starts MariaDB and Redis containers as part of the same stack.

Create sites

# erp.your-domain.com
docker compose --project-name erpnext exec backend \
  bench new-site --mariadb-user-host-login-scope=% --db-root-password changeit --install-app erpnext --admin-password changeit erp.your-domain.com

# crm.your-domain.com
docker compose --project-name erpnext exec backend \
  bench new-site --mariadb-user-host-login-scope=% --db-root-password changeit --install-app erpnext --admin-password changeit crm.your-domain.com

Notes

• Let's Encrypt requires ports 80 and 443 to be reachable from the internet.
• If you cannot expose these ports (LAN-only), omit compose.nginxproxy-ssl.yaml and use HTTP or a local TLS proxy like Caddy.
• Replace changeit with a strong DB root password and set a strong admin password per site.

Site operations

Refer: site operations

Troubleshooting (ACME / certificates)

• No certificate issued: Verify DNS points to the server IP and ports 80/443 are reachable from the internet.
• ACME errors in logs: Check acme-companion logs for the exact challenge error.
• Wrong hostname: Ensure the domain is included in NGINX_PROXY_HOSTS and that you restarted the stack after edits.
