ROOMZ Server On-Premise

Technical requirements

Server Software

Windows Server 2019 Container 

  • Version 1809 or higher

  • OS Build: latest

(current version can be found using the command 'winver'. Windows Update could be necessary for reaching the minimal patch version)

Server Hardware

Physical or Virtual Machine (VM)

Processor : 2.5 Ghz (Dual Core)

RAM : 8 GB (16 GB recommended)

Storage : 50 GB

DNS Entries

5 DNS entries redirected to the On-Premise Server.

For this first entry, ROOMZ will generate the certificate during the installation :


For those 4 entries, the organization must create the certificates  :

(The self signed certificate can use a wildcard. Thus, only one certificate could be issued for all the entries. Eg: "*")






  • Open

  • WPA2 - Personal (PSK)

  • WPA2 - Enterprise 

    • EAP-TLS (Certificates)

    • PEAPv0 / EAP- MSCHAPv2 (Username - Password)

Working SMTP address

Used in order to send invitations for the users, and send notifications

Internet connection

Only necessary during installation and updates (the download happens in an elevated Powershell). In normal duty, The ROOMZ server can be totally disconnected from the Internet

IMPORTANT: VMware Tools minimum version 11.0.6 is necessary

An issue exists with VMware Tools lower than the version 11.0.6 and the docker networks, you have to update the VMWare Tools to the version 11.0.6 at least.

Docker engine

If you don't have the Docker Engine installed, please follow the instructions to install Docker Enterprise on your server.

Docker compose

If you don't have the Docker Compose installed, please follow the instructions to install it.

Docker and the Antivirus software

Firewall DNS Whitelist

To be able to download all packages from the Internet, the following addresses should be reachable from the server.

This is only necessary during the installation, and the access can be deactivated once ROOMZ On-Premise is up and running.

ROOMZ Registry

Microsoft Registry

Microsoft Powershell Gallery




Windows Defender exceptions

In order for the installation to work flawlessly and the system to run as smoothly as possible, please add the following exceptions to Windows Defender:



Docker behind a corporate proxy

To configure the Docker client behind a proxy, you have to configure the Docker service to use your proxy.


Often the customer certificate is provided as PFX/P12 but NGINX doesn't support it. We have to convert the format PFX/P12 to a format more generic which is called PEM. The command line tool OpenSSL provide an easy way to explode the certificate in 2 parts, the certificate(only) and the key of the certificate which is used to make the cryptographic operations.

This is NOT MANDATORY to install the OpenSSL command line on the server, you can install it anywhere, execute the commands and move the certificate files(*.crt, *.key) to the server.

To extract the certificate and its parents, execute the following command in your terminal, this file will contain information of your server and organization.

1 openssl pkcs12 -in <pfx-file-path> -nokeys -out cert.crt -clcerts -chain

To extract the private key, execute the following command in your terminal, this file will contain the cryptographic key to make the SSL handshake between the server and the clients.

1 openssl pkcs12 -in <pfx-file-path> -nocerts -out cert.key -nodes

Once the files(*.crt, .key) moved to the server, in the ROOMZ certificate folder(e.g. C:\ROOMZ\Certificates), replace each files by your files(*.crt, *.key).

Which files should be replaced to use my SSL certificate

All ROOMZ certificates are in the folder ROOMZ\Certificates, which is often C:\ROOMZ\Certificates.

By default, you should replace the files login-cert.crt, login-cert.key, portal-cert.crt, portal-cert.key, portal-api-cert.crt, portal-api-cert.key, viewer-cert.crt, viewer-cert.key and set your certificate password in the files login-cert.pass, portal-cert.pass, portal-api-cert.pass, viewer-cert.pass by your certificate files(*.crt, *.key) extracted using OpenSSL.

Windows SQL Authentication

ROOMZ On-Premise uses a SQL Database, which will be installed during the setup.

If you wish to use the Windows Authentication, you have to follow those steps in your domain controller. The steps will create a file containing metadata of the provided gMSA name as the computer account for the container. Copy the generated file into the host folder C:\ProgramData\Docker\CredentialSpecs and the new instruction must be added in the docker-compose.yml file in the container section which will use the Windows Authentication (often SQL).

SQL Database size 

The SQL Database will grow from approximately 20MB every year by workspace.

We suggest a database size of 5GB on premise.

SMTP Server

ROOMZ needs an access to your SMTP server to send invitation for the new users created in the portal. To test the SMTP configuration before adding it into the .env file on your server, you can test the settings using the following command.

1 docker run -it --rm <host> <port> <sender> <recipient> <useSsl> [<username> <password>]

To have more information about the arguments, type the following command without arguments passed to the tester.

1 docker run -it --rm


1 docker run -it --rm Azure Container Registry | Microsoft Azure 547 false myUserName myPassword

Web browser compatibility 

To ensure best performance of ROOMZ, please make sure to always have the latest version of your web browser installed on the machine accessing to the portal

ROOMZ is compatible with the following browsers: 

  • Chrome

  • Firefox

  • Edge Chromium

Offline installation (not recommended)



Please follow the instructions from Mirantis to install the Docker engine, download the docker-compose cli and put the executable into the folder C:\ProgramFiles\Docker of your server.


Download the ROOMZ archive containing the images from a computer with an internet access, copy the archive on your server, unzip the archive on your server and import the images by executing the following commands where the images are.

The ROOMZ Archive is not available to download on the portal and can only be provided by ROOMZ


An instance of SQL Express is included in the container. The next steps assume that you are using this default instance and not your own SQL server 


It's recommended to use Powershell as terminal for the following instructions.

On your offline server, please follow the instructions.

  1. Configure your anti-virus software, by following the Docker instructions and exclude the processes dockerd.exe, dotnet.exe, erl.exe and node.exe too.

  2. Copy the archive into the folder C:\ROOMZ.

  3. Unzip the archive and import the images by executing the following commands where the images are.

    1 2 3 4 5 6 7 8 9 docker load -i redis.tar docker load -i mssql.tar docker load -i rabbitmq.tar docker load -i identity-server.tar docker load -i frontend-api.tar docker load -i device-api.tar docker load -i viewer.tar docker load -i proxy.tar docker load -i scheduler.tar

  4. We assume that ALL next commands will be executed in the working directory C:\ROOMZ.

  5. ROOMZ needs an SMTP server to send the invitations to the new users created in the portal, you can use our small tool dockerized to test your credentials before adding them in the configuration file.

  6. Update the file .env by updating the placeholders { } with your credentials (username, password, etc.) and remove the ones you don't use.

  7. To start the ROOMZ environment for the first time, type the command.

    1 docker-compose up --force-recreate --abort-on-container-exit
  8. ROOMZ is Live !


By default, docker is not configured to limit the log files created by the running container, you have to configure it to limit the files created and their sizes.
