I want to implement an automatic bash script which enters a running docker container, and do some stuffs:

# cat docker.sh
#!/bin/bash -x

docker exec -it hammerdb_net8 bash
cd /data/oracle/tablespaces/
pwd

Executing the script on terminal:

# ./docker.sh
+ docker exec -it hammerdb_net8 bash
[root@npar1 /]#

The output shows only login the docker container, but won't do other operations.

Is there any method to automate entering docker container and doing other things?
