Oracle's latest long-term release now has a developer-focused version available. Hopefully, our pleads for simplicity for the new setup are starting to show.
Note: The ORDS docker image is using ORDS 24.1 but with Apex 23.2. You can build your own image with the latest version of Apex or update the ORDS container to host the new 24.1 Apex images. See this section for the latter.
I was able to modify my previous 21c docker setup with success.
Notable changes: no container registry login required, faster container runtime due to PDB being already set up, removal of Enterprise Manager. :(
I am using Ubuntu 22.04 fresh installation.
To start the container, we need to prepare a directory for the database files, which is mounted into the container and is persistent (so we can store and save everything, which is one of the basic things a database is used for). For this, I create a directory and set the userid and group id of the Oracle user (inside the container!)
Setup a user for the Oracle database
sudo groupadd --system --gid 54321 oracle
sudo adduser --system --shell /usr/sbin/nologin --gid 54321 --uid 54321 oracle
Create the required volume folders and permissions
mkdir ~/oracle
mkdir ~/oracle/db
mkdir ~/oracle/ords
mkdir ~/oracle/db/oradata
mkdir ~/oracle/ords/ords_config
mkdir ~/oracle/ords/ords_secrets
mkdir ~/oracle/db/startup
mkdir ~/oracle/db/setup
sudo chmod 777 ~/oracle -R
sudo chown oracle:oracle ~/oracle/db/oradata
Setup firewall
sudo ufw allow 1521

Replace <PASSWORD>, <EMAIL> below. If running for a CI/CD setup consider using the lite version 23.4.0.0-lite
The Lite image has a smaller storage footprint than the Full image (~80% image size reduction) and a substantial improvement in image pull time. This image is useful in CI/CD scenarios and for simpler use cases where advanced database features are not required.

We need the DB to start before ORDS so run docker compose up database
Wait until you see
oracle-database-1 |
oracle-database-1 | DATABASE IS READY TO USE!
oracle-database-1 |
ORDS Setup
Create a conn_string.txt to load the credentials into ORDS. This file is deleted when the container starts, and must be replaced if wrong values are provided. Replace <PASSWORD>
Note: the default 23c SID is FREEPDB1
database is the service name from the docker-compose file
echo 'CONN_STRING=sys/<PASSWORD>@database:1521/FREEPDB1' > ~/oracle/ords/ords_secrets/conn_string.txt
If everything is correct then use docker compose up to start the remaining ORDS service.
Use the below login credentials for first-time login to APEX service: (Also found in the container logs)
Workspace: internal
User: ADMIN
Password: Welcome_1
Create your workspace and enjoy getting the basic's started. :)
Misc Commands
View ORDS logs:
docker exec -it oracle-ords-1 tail -f /tmp/install_container.log
View logs of the database, limit to last 1k:
docker logs oracle-database-1 -n 1000
To access the running container:
docker exec -it oracle-database-1 /bin/bash
Edit ORDS Config:
nano ords/ords_config/databases/default/pool.xml
Setup ORDS SSL:
cd ~/oracle/ords
mkdir -p ords_config/ssl
cp cert_file.crt ords_config/ssl/cert.crt
cp key_file.key ords_config/ssl/key.key
Update ORDS Apex images to 24.1
Since ORDS docker image has Apex bundled together you will have to point the ORDS config to look at new version 24.1 images. Otherwise you will be prompted of an error on login.
Run the standard Apex upgrade path to install the new Apex 24 schema. After installation, we have to update the images on the web server.
Download apex_latest.zip from the Oracle website, and mount the images directory in docker-compose file:
- ~/apex_latest/images/:/opt/oracle/apex_images/24/
Now edit the ORDS config to assign apex-images config variable to the path inside the container.
nano ords/ords_config/global/settings.xml
add entry:<entry key="apex-images">/opt/oracle/apex/images/24/</entry>
Restart the docker container
Most importantly, clear the browser cache. All new images and icons will be available.
