i am using the following docker run for admin server
docker run -d -p 7001:7001 --name oamadmin --network=OamNET --env-file /home/oam/oracle/oam-admin.env --shm-size="8g" --volume /home/oam/oracle/user_projects:/u01/oracle/user_projects oam:12.2.1.4
oam-admin.env content:

oracle database is created using:
docker run -d --name oamDB --network=oamNET -p 1521:1521 -p 5500:5500 -e ORACLE_PWD=db1 -v /home/oam/user/host/dbtemp:/opt/oracle/oradata --env-file /home/oam/oracle/env.txt -it --shm-size="8g" -e ORACLE_EDITION=enterprise e ORACLE_ALLOW_REMOTE=true oamdb:19.3.0
i am able to connect to DB using docker
