Docker container interact mode auto closing issue in docker-machine

Question

I have installed Docker using Docker toolbox in my Windows 7. I have installed Cassandra container. I am able to interact with container by ( docker exec -it <CON_ID> /bin/bash. after entering few commands in container , i am kicking out of the container.But, container is still running. example I am giving simple PWD, ls commands.

How to extend interact time in container ?

Docker toolbox version: 1.12.2

I didn't create any docker file for container. I have followed below steps,

1. docker run --name=mycass -d -it -p 9042:9042 cassandra:2.1.11

2. docker exec -it mycass /bin/bash

I am able to interact with container . after simple 2 commands ( pwd, ls ) getting kicked out from container.

Answer 1

I have executed ( docker-machine ssh default ) command and it opened Boot2Docker after that I am bale to connect container with interactive mode ( docker exec -it /bin/bash/ without any session close. But I don't the technical reason behind this.
