Installation
The Chart for Cased Shell is distributed as an OCI image. Contact Cased for access to the image.
Construct a values file using the documentation below as a reference making sure to set config.secret and ingress.fqdn and any other values required for your deployment:
postgresql.* values influence where relational data is stored.
vault.* values influence where secrets are stored.
config.objectStorageBackend influences where object storage is stored.
Install the Chart using helm install, helm upgrade --install, or using your preferred CI/CD system.
