What

Docker

Login

You'll be logged out after changing password automatically to login with the new credentials.

Admin email id and default admin password can be changed in the config file (explained below) after the first run. Each time the password is reset in the config file, The password needs to be changed again once logged in for security.

Production Setup

It's recommended to try the demo application first before using the production application. The production application requires a registered domain and special config variables for SSL as detailed in the configuration section.

mkdir oph-production && cd oph-production
sh -c "$(curl -fsSL https://raw.githubusercontent.com/abishekmuthian/open-payment-host/main/samples/oph-production/install-production.sh)"

After the container has started successfully, Stop the container, Set the required production configuration and re-run the container.

Configuration

Config file fragmenta.json is located in the secrets folder. It is generated automatically during the first run, After editing the config file the application needs to be restarted for the new configuration to take effect.

fragmenta.json contains configuration for both development and production. The production configuration is loaded when the environment variable FRAG_ENV=production is set.
