Polyaxon ships with a default redis based on the stable Helm chart.
You can check the chart values to extend its configuration.
If you prefer to have Redis managed by you or hosted outside of Kubernetes, you need to disable the in-cluster redis, and provide the information needed to establish a connection to the external one, e.g.:
broker: redis redis: enabled: false externalServices: redis: password: polyaxon host: 35.262.163.88
If your redis instance requires a password, you need to provide it as well:
broker: redis redis: enabled: false externalServices: redis: usePassword: true password: polyaxon host: 35.262.163.88 port: 1234
You can also use Redis for as async worker broker, please check this section on how to alter the default broker behavior.
If you decided to deploy Redis in-cluster make sure to set proper node scheduling to avoid running high load runs on the same node hosting Redis.
