-## 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.

+#### 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].
