I want to use Hadoop from CDH docker image. CDH image is already installed on my machine and I can run it.

> ```auto
> docker ps -a
> 
> CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
> 07a55a9d4cb9 4239cd2958c6 "/usr/bin/docker-quickstart" 18 minutes ago Up 18 minutes 0.0.0.0:32774->7180/tcp, 0.0.0.0:32773->8888/tcp container
> 
> docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container
> 
> 172.17.0.2

Local, I am writing an ansible playbook and I need to set Hadoop conf dir in CDH which is: “/etc/hadoop/conf”. How can I set the running docker image in my ansible playbook?

I tried:

> ```auto
> - name: run cloudera
> docker_container:
> name: "container"
> image: quickstart/cloudera
> command: /usr/bin/docker-quickstart"
> state: started
> ports:
> - 8888:8888
> - 7180:7180
> 
> ```

But this command runs another docker image and I would like to connect to the running one.

Probably the easiest thing to do is forward a port to ssh in your container when you launch it and then connect to that in Ansible like a standard host. That should be quite easy to do.

A quick google also shows this…

Not used it but again it looks simple enough.
