+# MinIO with TLS from secret-operator
+
+MinIO has a severe limitation whereby the TLS certificates must be named `public.crt`
+and `private.key`. This goes against Kubernetes naming of `tls.crt` and `tls.key`.
+
+The upstream minio chart is also too limited:
+
+- No way to add initContainers (to rename cert files in a shared volume).
+- No way to edit the container command (to rename cert files before starting minio).
+
+Therefore, we will render the upstream chart here, and then apply the necessary
+customizations on top.
+
+```yaml
+helm template minio minio/minio -f values.yaml > rendered-chart.yaml
+```
