Siyao Meng commented on HDDS-3497:
----------------------------------

Hi [~maobaolong], this is more of a docker-compose file management thing. You will have to explicitly map the datanode port out to the host in order to make it accessible from host.

From:
{code:title=https://github.com/apache/ozone/blob/88f39dfaf53f382a5567b4e816e8c8e90db7df88/hadoop-ozone/dist/src/main/compose/ozone/docker-compose.yaml#L33-L37}
  datanode:
    <<: *common-config
    ports:
      - 9864
      - 9882
{code}

To:
{code}
  datanode:
    <<: *common-config
    ports:
      - 9864:9864
      - 9882:9882
{code}

Also we usually use ozone shell inside container (not on the host directly). Hope this helps.

> Now i using docker-compose to start a ozone cluster, and i create volume and bucket, but i cannot put some file into this ozone cluster in my host node.
> Following is the step to reproduce.
> ozone-0.6.0-SNAPSHOT/compose/ozone/run.sh
> pwd=ozone-0.6.0-SNAPSHOT
> bin/ozone sh vol create myvol
> bin/ozone sh bucket create myvol/mybucket
> bin/ozone sh key put /myvol/mybucket/README.md README.md
> The last command stuck. 
> And i do some debug work. I see the ratis pipeline here with nodes using ip:port, in the host node, i cannot access these ip in another network
