Make sure that you have build the workspace and the Docker images. To build the Docker images the Maven profile default-image must be activated. To check whether you have build the images you can list the available images using the following command:

docker images

The result should look like this but should contain image names like cae-live or content-server:

REPOSITORY                 TAG     IMAGE ID      CREATED       SIZE
coremedia/cae-preview      latest  a8f9d245fbbe  10 hours ago  296MB
coremedia/content-server   latest  8f6045472222  10 hours ago  272MB

If there are no images listed, you probably did not activate the Maven profile. To build with the active Maven profile, run the following command:

mvn clean install -Pdefault-image

After the images have been built, you can change the directory to the docker setup:

cd global/deployment/docker
