ORA-12547: TNS:lost contact - oracle-xe

Question

I downloaded a docker container with oraclexe 11g on Ubuntu 14.
Everything worked as expected, i created tables, insert data, etc and then i commit the container, generating a new image(same oracle image, but with my tables and data).
Problem:
I can´t connect to my database in my newly created image, either local or remote.
Any tips on that error?

Answer 1

The problem is with the dockerfile mounting the oracle data folder
VOLUME "/u01/app/oracle"
When i commit my container, this folder is not saved into my new image, generating the errors to start the db.
