+# Multiple Services
+
+## With a single controller
+
+It is possible to have multiple Service objects that point to a single controller.
+
+### Example
+
+```yaml
+controllers:
+  main:
+    containers:
+      main:
+        image:
+          repository: ghcr.io/mendhak/http-https-echo
+          tag: 30
+          pullPolicy: IfNotPresent
+
+service:
+  main:
+    # The controller for this service is set to
+    # "main" by the default app-template values
+    # controller: main
+    ports:
+      http:
+        port: 8080
+  second:
+    controller: main # (1)!
+    ports:
+      http:
+        port: 8081
+```
+
+1. Point to the controller with the "main" identifier
+
+## With multiple controllers
+
+It is also possible have multiple Service objects that point to different controllers.
+
+### Example
+
+```yaml
+controllers:
+  main:
+    containers:
+      main:
+        image:
+          repository: ghcr.io/mendhak/http-https-echo
+          tag: 30
+          pullPolicy: IfNotPresent
+  second:
+    containers:
+      main:
+        image:
+          repository: ghcr.io/mendhak/http-https-echo
+          tag: 30
+          pullPolicy: IfNotPresent
+
+service:
+  main:
+    # The controller for this service is set to
+    # "main" by the default app-template values
+    # controller: main
+    ports:
+      http:
+        port: 8080
+  second:
+    controller: main # (1)!
+    ports:
+      http:
+        port: 8081
+  third:
+    controller: second # (2)!
+    ports:
+      http:
+        port: 8081
+```
