-## Troubleshooting steps
+## Cert-Manager
+
+Cert Manager will be used as it will store certs in a secret, therefore accessible for every pod.
+In contrast to this, Traefik stores certs on disk, so a volume would be needed in RWX mode (too much effort).
+
+### Issuer - CA
+An issuer is a CA. This can be done with 2 different kinds.
+
+#### Issuer 
+can be used in the namespace they are created in.
+
+#### Cluster Issuer 
+can be used throughout the whole cluster, not limited to a specific namespace.
+i.e. general issuer for all namespaces in cluster.

 ### 1. Stelle sicher, dass Longhorn installiert ist
 Zuerst solltest du sicherstellen, dass Longhorn auf deinem Cluster installiert ist. Falls Longhorn noch nicht installiert ist, kannst du es mit Helm oder direkt aus den YAML-Dateien installieren.

+#### Node Labeling
+
+In the case not all nodes should provide disk, e.g. certain nodes have special/fast disks.
+In this case the StorageClass needs to be adapted and added with a nodeselector [1].
