can not connect to oracledb running in a docker container

Question

Mac OS and docker From the oracledb console, I can not connect as sys, password I type in oracle and no go

SQL> connect sys as sysdba;
Enter password: 
ERROR:
ORA-12547: TNS:lost contact

how did I get this far...

    docker pull absolutapps/oracle-12c-ee
    docker run -d --name oracle-12cR1-ee --privileged absolutapps/oracle-12c-ee
    docker logs -f oracle-12cR1-ee

at then end of that I get

PL/SQL procedure successfully completed.

Please login to http://<ip_address>:8080/em to use enterprise manager
User: sys; Password oracle; Sysdba: true
Fixing permissions...
Running init scripts...
Init scripts in /oracle.init.d/: Ignoring /oracle.init.d/*

Done with scripts we are ready to go

Next command I run is

docker exec -it 28b0f34f7a81 bash -c "source /home/oracle/.bashrc; sqlplus /nolog"

Looking at the source code for that image you're using I was able to see that they're using gosu oracle sqlplus to connect to the database with elevated privileges, so I tried this in my environment and seems to fit perfectly to what you need:

docker exec -it oracle-12cR1-ee sh -c 'gosu oracle sqlplus "sys as sysdba"'

getting..

Connected to:

and then being able to (for example):

SQL> SELECT USERNAME from SYS.ALL_USERS;

Enjoy! ;)

Edit:

Using just sqlplus / as sysdba also works as well, so it would be:

docker exec -it oracle-12cR1-ee sh -c 'gosu oracle sqlplus / as sysdba'
