Expected behavior

• This new version of Connaisseur uses redis caching. We were using chart version 2.0 application version 3.0.0 which did not have redis. The expectation is that for the new versions with redis, the logs will be clean without errors.

Optional: To reproduce

To reproduce, install Connaisseur application version 3.6.1 and chart version 2.6.1 on AWS EKS v1.30 **Optional: Versions (please complete the following information as relevant):** - OS: Amazon Linux - Kubernetes Cluster: EKS 1.30 - Notary Server: - Container registry: containerd - Connaisseur: chart 2.6.1 application 3.6.1 - Other: **Optional: Additional context** * Using the default values for Connaisseur application version 3.6.1 and chart version 2.6.1 results in the redis log errors * To try resolve the failure in the logs`Failed opening the temp RDB file temp-123086.rdb (in server root dir /data) for saving: Permission denied ` , we also tried adding below to `values.yaml` in order for redis not to run under restricted security context. This also didnt work ``` redis: securityContext: {} ```
