Here is my docker-compose.yml file:
version: '3.7'
services:
database:
image: scgain.azurecr.io/databases/${IMAGE_NAME}
environment:
- ORACLE_SID=${SID}
- ORACLE_PDB=${PDB}
- ORACLE_PWD=somepassword
- ORACLE_CHARACTERSET=WE8MSWIN1252
volumes:
- ${ORACLE_HOST_DIR}oradata:/opt/oracle/oradata # persistent oracle database data
- ${ORACLE_HOST_DIR}data-bridge:/data-bridge # share data with the running container
ports:
- 1521:1521
- 8080:8080
- 5500:5500
and here the corresponding .env file:
IMAGE_NAME=oracle-19-e
SID=ORCL19CDB
PDB=ORCL19PDB1
ORACLE_HOST_DIR=D:\src\oracle\
When I run this container in Windows via PowerShell, I can connect to the Oracle instance just fine via SQL Developer (through hostname localhost and port 1521) and with my app using this connection string:
Host=localhost;Port=1521;User ID=someuser;Password=somepassword;Service Name=ORCL19PDB1;Direct=true
When I run it instead in WSL2 (Ubuntu 20,04) I can browse the mapped volumes inside the container. I can connect to the instance inside the container via sqlplus and see all the schemas and tables, but trying to connect to it through SQL Developer gives me a Code 17002 error (unable to establish connection). Also, my app throws an analogous exception that it cannot find the database.
Here is the .env file for Linux:
IMAGE_NAME=oracle-19-e
SID=ORCL19CDB
PDB=ORCL19PDB1
ORACLE_HOST_DIR=/mnt/d/src/oracle/
I checked with lsnrctl status that the TNS listener is running inside the container.

The command completed successfully
What do I need to do to connect to the db outside of its container when it is running in WSL2?

Well, I found the culprit. The port assignment
- 8080:8080
is not needed (it was legacy from previous work), and once I take it out, I can connect via SQL Developer and my app is happy as well. Not sure I understand the reason, but for now I am back in business.
