+# Docspell Kubernetes Setup
+
+This folder contains the necessary Kubernetes manifests, as well as a [Kustomization](https://kustomize.io/), to deploy docspell to a Kubernetes cluster.
+
+## Using Kustomize
+
+To deploy a basic installation using Kustomize, you can use the following command:
+
+``` shell
+kubectl apply -k https://raw.githubusercontent.com/eikek/docspell/master/kubernetes
+```
+
+For a more advanced and production ready setup, create your own kustomization.yaml, changing the secret value and replica counts as necessary:
+
+``` yaml
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+resources:
+- github.com/eikek/docspell.git//kubernetes?timeout=90s&ref=master
+patches:
+- target:
+    kind: Deployment
+    name: restserver
+  patch: |-
+    - op: replace
+      path: /spec/replicas
+      value: 2
+    - op: replace
+      path: /spec/template/spec/containers/0/image
+      value: docspell/restserver:v0.40.0
+- target:
+    kind: Deployment
+    name: joex
+  patch: |-
+    - op: replace
+      path: /spec/template/spec/containers/0/image
+      value: docspell/joex:v0.40.0
+- target:
+    kind: Secret
+    name: restserver-secrets
+  patch: |-
+    - op: replace
+      path: /data/DOCSPELL_SERVER_BACKEND_JDBC_PASSWORD
+      value: ZGJwYXNzMg== # dbpass2
+    - op: replace
+      path: /data/DOCSPELL_JOEX_JDBC_PASSWORD
+      value: ZGJwYXNzMg== # dbpass2
+```
+
+And apply your kustomization:
+
+``` shell
+kubectl apply -k .
+```
+
+## Using Kubernetes manifests
+
+To deploy a basic installation using the Kubernetes manifests, you can use the following command:
+
+``` shell
+kubectl apply -f https://raw.githubusercontent.com/eikek/docspell/master/kubernetes
+```
