Docker Compose-based production installation

This installation requires a separately available PostgreSQL database and is intended for the production deployment of Governor. If you prefer an easier option to install Governor for evaluation and demonstration purposes, use the demo setup instead.

Prerequisites

Docker must be available on the production server.
PostgreSQL server (version 13 or later) must be available in order to hold the Governor database. Empty database should be created prior to installation of Governor and login credentials for this database should be known.
Download and unzip governor-compose-prod.zip. This file contains recommended setup for backend (JVM-based) and frontend (nginx-based) Docker containers.

Setting up Docker Compose

Setting up the access to the Governor database

Modify the following lines in the docker-compose file:

- SPRING_DATASOURCE_URL=jdbc:postgresql://host.docker.internal:5432/governor (1)
- SPRING_DATASOURCE_USERNAME=apiuser (2)
- SPRING_DATASOURCE_PASSWORD=apipassword (3)

Modify JDBC URL in order to point to your PostgreSQL database for Governor. If it is being run on the same host as Docker images for Governor, then host.docker.internal can be used as a host name.
Set the correct user name for Governor database
Set the correct password for Governor database

Configuring the JWT Secret

Generate a JWT secret to serve as the signing key for authentication. Follow these steps based on your operating system:

Mac/Linux
Windows (Powershell)

openssl rand -base64 256 | tr -d '\n'

[Convert]::ToBase64String((Get-Random -Count 256 -InputObject (0..255)))

After generating the key, replace [your jwt secret] in the docker-compose.yml file with the newly generated secret key.

Configuring Synthesized License

Insert your Synthesized license key into the docker-compose.yml file by replacing [your synthesized key].

(Optional) Setting up volumes for logs and RocksDB

In most scenarios, it makes sense to keep logs and RocksDB storage on the host’s filesystem, not the Docker’s internal filesystem.

In order to do so, uncomment the following lines in the docker-compose.yml:

    # volumes:
      # - [your path to rocksdb]:/app/rocksdb
      # - [your path to logs]:/app/logs

substitute [your path to rocksdb] to the path where you would like to store RocksDB data
substitute [your path to logs] to the path where you would like to store application logs.

The required free disk space for partitions containing RocksDB and logs heavily depends on your usage scenarios, we recommend that at least 100Gb must be available for production usage.

Running

Use the detached mode of docker compose to run the Governor containers in production:

docker compose up --detach

The Governor UI will be available at http://localhost:80. Use the predefined username and password to log in for the first time: test@synthesized.io / Qq12345_. After logging in, create a new user with a secure password and delete the predefined one.

Use docker compose ps command in order to make sure that backend and frontend services are both running and in healthy state. The most common source of potential problems is connectivity to the database. Verify that database connection URL, username and password are correct, check backend logs (docker compose logs backend) for details if the problem persists.

Setting up TLS termination

Governor requires https:// protocol in order to run successfully from any address besides localhost. If you want to set up a domain name for Governor, you have to set up TLS termination as well.

The simplest way to do so is to install nginx and provide domain certificates.

Setup nginx.
Create a file named after your domain in /etc/nginx/sites-available with the following

server {
    listen 443 ssl;
    server_name [domain name];

    ssl_certificate [path-to-your-certificate]/fullchain.pem;
    ssl_certificate_key [path-to-your-certificate]/privkey.pem;

    location / {
        proxy_pass http://localhost:80;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

In this file
- [domain name] is the domain name for your website, e.g. governor.example.com.
- [path-to-your-certificate] is the folder where website certificates are stored.
Create a symlink with nginx configuration from /etc/nginx/sites-available to /etc/nginx/sites-enabled
Execute nginx -s reload.
