Howto install Oracle client on LPAR2RRD / STOR2RRD in a Docker?

Hello.
I just created my LPAR2RRD / STOR2RRD in a Docker.
Now, i am trying to configure Oracle Databases withou success.

I added a Database Configuration and during "Connectio Test", it is being raised:
================================================================================
DB host network connection: TCP connection to 10.100.x.x:1526 is OK.
DB data test: 10.100.x.x
Command not found, is the instantclient version in variables below correct?

ORACLE_BASE: /opt/oracle
ORACLE_HOME: /opt/oracle/instantclient_18_5
LIBPATH(AIX):
LD_LIBRARY_PATH(Linux): /opt/oracle/instantclient_18_5:
================================================================================

I followed the procedures:
https://lpar2rrd.com/docker.php
https://lpar2rrd.com/OracleDB-performance-monitoring-install.php#OracleDB

I believe there is an error regarding Oracle Instant Client on Docker image - Alpine Linux
During a simple test trying to call "sqlplus", i got the error:
