-----------------------------------

             Summary: Containers that use the Mesos containerizer but don't want to provision a container image fail to validate.
                 Key: MESOS-6209
                 URL: https://issues.apache.org/jira/browse/MESOS-6209
             Project: Mesos
          Issue Type: Bug
          Components: containerization
         Environment: Mesos HEAD, change was introduced with e65f580bf0cbea64cedf521cf169b9b4c9f85454
            Reporter: Jan Schlicht


Tasks using  features like volumes or CNI in their containers, have to define these in {{TaskInfo.container}}. When these tasks don't want/need to provision a container image, neither {{ContainerInfo.docker}} nor {{ContainerInfo.mesos}} will be set. Nevertheless, the container type in {{ContainerInfo.type}} needs to be set, because it is a required field.
In that case, the recently introduced validation rules in {{master/validation.cpp}} ({{validateContainerInfo}} will fail, which isn't expected.
