docker: Error response from daemon: Conflict. The container name "/logstash" is already in use by container "39f1c67063ea455bfa235bbe98be4e90bd87c2f7864d856f0a7b17c32ae75fa0". You have to remove (or rename) that container to be able to reuse that name.
See 'docker run --help'.

# SOLVE
docker container rm logstash

docker ps | grep logstash
发现logstash容器没有起来，配置不对
