To deploy the themes you need to create a JAR archive with the theme resources.
jar cf FDPG.jar theme/ META-INF/
on your Terminal to create a JAR file with the name "FDPG" and the theme and META-INF files in it.
Then copy the newly created JAR file to the deployments directory of your keycloak container
docker cp /path/to/FDPG.jar yourkeycloakcontainer:/opt/jboss/keycloak/standalone/deployments/
And select the login theme "FDPG" from the dropdown menu in the keycloak admin console.
