An Otter Wiki is published both as the full `redimp/otterwiki:2` image and the lighter `redimp/otterwiki:2-slim` variant, see [[the -slim image variant|Installation#the-slim-image-variant]] for the differences between them. The two are interchangeable, but mind the port when switching: the `-slim` image listens only on port 8080, while the full image listens on both port 80 and port 8080. A port mapping onto the container's port 8080, for example `-p 8080:8080`, therefore works with either variant. A mapping onto port 80, like `-p 8080:80`, works only with the full image, so change it to the container's port 8080 before switching to `-slim`.
