+# Heimdall
+
+## Basic stuff
+
+### Install
+
+```shell
+helm install heimdall ./helm --namespace heimdall --create-namespace
+```
+
+### Update
+
+```shell
+helm -n heimdall upgrade heimdall .\helm\
+```
+

+```shell
+kubectl -n heimdall get cm,pvc,pod,svc
+```
+
+### Tail Log
+
+```shell
+kubectl -n heimdall logs -f heimdall-0
+```
+
+### Delete
+
+```shell
+kubectl delete ns heimdall
+```
+
+## Immigration
+
+We need to find the location for the files
+
+### Step 1
+
+```shell
+kubectl -n heimdall get pvc data-heimdall-0 -o wide
+```
+
+Output:
+
+```
+NAME              STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS        VOLUMEATTRIBUTESCLASS   AGE   VOLUMEMODE
+data-heimdall-0   Bound    pvc-b84dce5e-bc04-456c-83c1-6f6f5f326040   1Gi        RWO            microk8s-hostpath   <unset>                 1m    Filesystem
+```
+
+we need the volume name in this case `pvc-b84dce5e-bc04-456c-83c1-6f6f5f326040`
+
+### Step 2
+
+```shell
+kubectl get pv pvc-b84dce5e-bc04-456c-83c1-6f6f5f326040 -o yaml
+```
+
+Output:
+
+```
+apiVersion: v1
+kind: PersistentVolume
+metadata:
+  ...
+spec:
+  accessModes:
+  - ReadWriteOnce
+  capacity:
+    storage: 1Gi
+  claimRef:
+    ...
+  hostPath:
+    path: /var/snap/microk8s/common/default-storage/heimdall-data-heimdall-0-pvc-b84dce5e-bc04-456c-83c1-6f6f5f326040
+    type: DirectoryOrCreate
+  nodeAffinity:
+    ...
+  persistentVolumeReclaimPolicy: Delete
+  storageClassName: microk8s-hostpath
+  volumeMode: Filesystem
+status:
+  ...
+```
+
+We need `spec -> hostPath -> path` in this case `/var/snap/microk8s/common/default-storage/heimdall-data-heimdall-0-pvc-b84dce5e-bc04-456c-83c1-6f6f5f326040`
+
+### Step 2
+
+Login to the old server. and use rsync, don't forget stuff like puid, pgid, file access and stuff.
+
+```shell
+rsync -avz -e ssh ./ username@0.0.0.0:/var/snap/microk8s/common/default-storage/heimdall-data-heimdall-0-pvc-b84dce5e-bc04-456c-83c1-6f6f5f326040
+```
