[LiuPeng_daoclou]

this is me docker-compose file to deployment splunk cluster,the server is a deployment server and master server,the indexer* is indexer cluster

                max-size: 100m
networks:
    splunk:
        external: true

when I add a http data input on my deployment server ,the universalforwarder will download the app,but not listen the 8088 port,what can I do for it
