+===== ERROR: Service 'logrotate' failed to build: invalid reference format =====
+Escenario:
+* Uso docker compose
+* Uso build dentro del docker compose
+* La imagen y la versión se pasan por parámetro
+**docker-compose.yml**
+<code>
+version: '3.7'
+services:
+ logrotate:
+  build:
+   context: ./path/to/dir
+   args:
+    - IMAGE=${IMAGE}
+    - VERSION=${VERSION}
+...
+</code>
+**Dockerfile** (dentro de './path/to/dir')
+<code>
+ARG IMAGE
+ARG VERSION
+FROM $IMAGE:$VERSION
+...
+</code>
+**.env**
+<code>
+IMAGE=
+VERSION=latest
+</code>
+Solución:
+Revisar que las variables "IMAGE" y "VERSION" sean coherentes. En este caso por error IMAGE estaba vacía
