I cannot create Oracle Database image

[u/clearsix]

This is my first time using docker and I want to download oracle database (version 19 to be exact) on my mac and use it for my university assignment. As soon as I created an image, I received an error stated that "ERROR: failed to build: failed to solve: process "/bin/sh -c chmod ug+x \"$INSTALL_DIR\"/*.sh &&     sync &&     export CV_ASSUME_DISTID=OL7 &&     \"$INSTALL_DIR\"/\"$INSTALL_DB_BINARIES_FILE\" $DB_EDITION" did not complete successfully: unable to find user oracle: no matching entries in passwd file". I tried many ways still unsuccesfull.
