We highly recommend relying on Minio instead of Redis if you are looking for a local persistant storage solution for Spinnaker. The Redis storage implementation is untested and unsupported by anyone in the Spinnaker community.
Redis can be used as Spinnaker’s persistent storage source, but it is unsupported and not recommended for production use-cases because it mixes fungible, short-lived cache entries with the Pipeline and Application data that deploy all of your infrastructure. This means you will have to be extra careful when clearing your Spinnaker Redis cache.
Currently, Halyard only allows you to use the Redis instance that Halyard provisions/installs on your behalf. While this is likely to change, for you don’t need to preconfigure anything to get this storage source working.
Editing Your Storage Settings
All that’s needed is the following command:
hal config storage edit --type redis
