Oracle-Db-Gvenzl Overview

Secure your stack with a hardened Oracle Database Free image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Oracle Database Free is an edition of the Oracle Database for development and testing. The Minimus image is based on the community gvenzl/oracle-free container image.

Try It Out

Take the Minimus Oracle Database Free image for a test run. The example below sets the SYS and SYSTEM password to Minimus! and creates an application user in the default FREEPDB1 pluggable database.

Step 1: Start the Database

Start a container and map the Oracle listener port to your host:

docker run -d --name minimus-oracle \
  -p 1521:1521 \
  -e ORACLE_PASSWORD=Minimus! \
  -e APP_USER=appuser \
  -e APP_USER_PASSWORD=Minimus! \
  reg.mini.dev/oracle-db-gvenzl

ORACLE_PASSWORD is required on the first container startup and sets the password for the SYS and SYSTEM users. APP_USER and APP_USER_PASSWORD create an application schema user in FREEPDB1.

The first startup can take several minutes while the database is initialized. Watch the logs until the database is ready:

docker logs -f minimus-oracle

You should see DATABASE IS READY TO USE!

Step 2: Connect with SQL*Plus

Open SQLPlus inside the container. Oracle Database Free creates a default pluggable database (PDB) named FREEPDB1, where the appuser account from Step 1 is created. Include @//localhost/FREEPDB1 in the connect string so SQLPlus reaches the PDB.

Wrap the connect string in single quotes so bash does not treat ! in the password as history expansion:

docker exec -it minimus-oracle sqlplus 'appuser/Minimus!@//localhost/FREEPDB1'

You should see the SQL*Plus prompt. Run a simple query:

SELECT 'Hello from Minimus!' AS greeting FROM dual;

Exit SQL*Plus:

EXIT;

Optional: Persist Data Across Restarts

To keep database files when the container is removed, mount a Docker volume at /opt/oracle/oradata:

docker run -d --name minimus-oracle \
  -p 1521:1521 \
  -e ORACLE_PASSWORD=Minimus! \
  -e APP_USER=appuser \
  -e APP_USER_PASSWORD=Minimus! \
  -v oracle-volume:/opt/oracle/oradata \
  reg.mini.dev/oracle-db-gvenzl

Clean Up

Stop and remove the test container (the named volume is kept unless you remove it separately):

docker rm -f minimus-oracle

Technical Considerations

The Oracle-Db-Gvenzl image provided by Minimus is a slim, security-hardened alternative to the public gvenzl/oracle-free image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.

Oracle-Db-Gvenzl built by Minimus:

Listens on port 1521/tcp for Oracle Net connections to the default pluggable database FREEPDB1.
On first startup, set ORACLE_PASSWORD (required). You can add optional variables, such as APP_USER, APP_USER_PASSWORD, and ORACLE_DATABASE.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
