How do I know what my username/password is for SQL PLUS? I am trying to set up an Oracle SOA Suite environment with docker containers according to this website -> https://svgonugu.com/2018/03/12/docker-containers-for-oracle-soa-suite/

I got to a point where I have to connect to a database with this command: sqlplus sys/fusion@//172.17.0.1:1521/soadb as sysdba

But it gives me the following error: 

ERROR:
ORA-01017: invalid username/password; logon denied


So what am I doing wrong here? I have not given a username or password during the whole process.
I have not given a username or password during the whole process.


Why not? It is clearly written on that site, right before the step where you try logging in with sqlplus.


  
  Execute docker exec &lt;&lt;container id&gt;&gt; /opt/oracle/setPassword.sh &lt;&lt;pwd&gt;&gt; to reset password for SYS user.
