How to Deploy Multiple Bold Reports Single Containers on the Same VM Using Different Ports.

Overview

This article explains how to deploy multiple instances of Bold Reports Docker single container on the same virtual machine when port 443 is already in use.

Since only one container can bind to a specific host port (e.g., 443), additional instances must use a different host port (e.g., 8085).

Prerequisites

Docker installed and running
First Bold Reports container already deployed on port 443
An available port (example: 8085)
Firewall/Security Group updated to allow inbound traffic on the new port
Separate persistent storage (recommended)

Applies To

Bold Reports
Docker-based single container deployment
Windows Server / Linux VM environments
Azure / AWS / On-prem environments

Scenario

Instance	Host Port	Container Port	Access URL
Bold Reports – Instance 1	443	443	https://demo.com
Bold Reports – Instance 2	8085	443	https://demo.com:8085

Note: The container’s internal HTTPS port remains 443. Only the host port mapping changes.

Solution

Step 1: Deploy Second Container Using a Different Port

Update the Docker Compose file for the second deployment:

Place the 2nd docker-compose.yaml file in different location
Change the 2nd container name as different name and change the port as well
Change the Postgres name as well

While deploying multiple Bold Reports instances on the same server, ensure that each deployment uses separate mount paths for:

app_data directory
PostgreSQL data directory
NGINX configuration directory

This prevents data and configuration conflicts between the instances.

Step 2: Start the Second Deployment

docker-compose up -d

Verify:

docker ps 

docker logs <container-id>

You should see:

0.0.0.0:8085->443/tcp

Step 3: Configure the nginx

Please follow below document to configure the nginx

Step 4: Restart the Container

docker-compose down
docker-compose up -d

Final Access URL

https://demo.com:8085
