I have create an image for the oracle 19c. I have started my container with below command.
docker run --name oracledb -d -p 1527:1521 -p 5700:5500 -e ORACLE_PWD=password1 -e ORACLE_CHARACTERSET=AL32UTF8 -v /d/docker-code/oracle-data oracle/database:19.3.0-ee
After creation of container, I am able to login in the container. I am able to connect with the below command inside the container.
sqlplus system/[email protected]:1527/ORCLCDB
Outside of the container, from the cmd, I can not connect to that oracle instance.
Note: I have already installed oracle on the windows machine at port 1521 which is default port.

(CONNECT_DATA =

I am not able to connect from SQL Developer or from CMD. I am able to get timeout error when I am trying to access outside of the docker container.
ERROR:
ORA-12170: TNS:Connect timeout occurred
Please guide me to resolve this issue.
Thanks in Advance.
Make sure all container network interfaces are listening for database traffic, hence 0.0.0.0. Do not hardcode a docker bridge network address (172..) because this address will be assigned at container startup. Just stick with the default port 1521 local to the container. This port - 1521 - is local to the container and not exposed to the host OS. You publish this port to the host OS where you decide which port to use, hence -p 1522:1521
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
)
)
Now you can fire up the container on your host OS by issuing:
docker run --name oracledb -d -p 1522:1521 -p 5700:5500 -e ORACLE_PWD=password1 -e ORACLE_CHARACTERSET=AL32UTF8 -v /d/docker-code/oracle-data oracle/database:19.3.0-ee
This should now work
sqlplus system/password1@localhost:1522/ORCLCDB
Tip. You can now pull Oracle XE 18c from Docker Hub. I recommend you to test this image if you still cannot connect using the image you have built.
docker run -d -p 1522:1521 --rm -e ORACLE_PASSWORD=Welcome_1 -v oracle-volume:/opt/oracle/oradata gvenzl/oracle-xe
docker container ls
