# Helm Charts

In order to be able to deploy DecisionRules on Kubernetes using Helm Charts, first make sure you have the prerequisite Redis and MongoDB instances already prepared and available and set the corresponding environment variables `REDIS_URL` and `MONGO_DB_URI` in values.yaml accordingly.

Also make sure you have properly set the 'client' and 'api' domains (and 'bi' if your license includes Business Intelligence) and then use them to construct the `CLIENT_URL` and `API_URL` variables.

Please refer to our official documentation page, which contains the complete list of all required [environment variables](https://docs.decisionrules.io/doc/other-deployment-options/docker-and-on-premise/containers-environmental-variables).
