I admit it, I was not a friend of Oracle databases running in Docker containers for a long time. My database systems for testing and demo purposes were all running in VMware, Virtual Box or in the Oracle Cloud. But I have used the Windows Subsystem for Linux since beginning, to work with the Oracle Oracle Cloud Infrastructure CLI, Git Integration etc.. And what I really like is the WSL extension for Visual Studio Code which gives me to chance, to edit Ansible Vault files in Windows without any additional Linux based VM running.
With the update of the existing Windows Subsystem for Linux (WSL) architecture to version 2, the Docker Desktop for Windows is now fully integrated and able to run Docker container in WSL as a lightweight VM. Now it’s time to change my mind, why not use Docker to try out new Oracle features, do some development stuff and more?
Sudo oracle-java8-installer8u131-1webupd82all.deb sudo oracle-java8-set-default8u131-1webupd82all.deb (and you can install the unlimited one, but not necessary by defalut) In contrary to the abandoned PPA, you can install these without problems and the ‘Oracle Java 8 Plugin Control Panel’ will work too. I’ve always been wondering how Docker works in this regards, and whether I should either make as many “RUN apt-get install” commands as possible, or if I should instead try to use as few RUN commands as possible, as these increases the number of layers (?). So for example: RUN apt-get update && apt-get install -y python-qt4 python-pyside python-pip python3-pip python3. To install InfluxDB on Docker, you have two ways of doing it. You can either prepare your filesystem manually, and run the InfluxDB on a Docker container with no initialization scripts. This is the simplest way of initializing InfluxDB. This blog post shows you how to setup WSL 2 to run Docker images. Sure, you can use the Oracle provided Docker images or self created images too. But I have verified the Oracle repository today, the Dockerfile version is 19.3.0. And I don’t have the passion, to create new Dockerfiles for example to run 19.8 and download additional RU software.
What to we need to run Oracle databases in WSL 2 Docker Containers?
- WSL 2
- Docker Desktop for Windows
- Docker images with an Oracle Database – I may use the images (oehrlis/docker) from my workmate Stefan Oehrli (oradba.ch)- merci vöumou

Docker Install Oracle 12c
Installing Windows Subsystem 2 for Linux
Enable Windows Subsystem for Linux basic Functionality
Start Windows PowerShell as Administrator and enable WSL.
Let’s check it with Windows logo key + R and winver – my version us 1904:
Enable the ‘Virtual Machine Platform’ – this component is required for WSL 2.
2 4 6 8 10 12 14 16 | tdb190c: container_name:tdb190c restart:unless-stopped volumes: -./config:/u01/config -'1521:1521' CONTAINER:'TRUE' ORACLE_SID:TDB190C |
After pulling, let’s start the container with docker-compose.
In the background, the database will be created and configured – example output in Docker Desktop.
SQL Developer Connect
Verify in the Shell if the Oracle database and the listener are running – example output from the Trivadis Toolbox component TVD-Basenv.
Summary
The integration of Docker in Windows Subsystem for Linux is fast and easy to configure. I like the idea to run a lightweight VM inside my existing WSL. In future, before I think about to start a VMware or Virtual Box VM to do some Oracle testing stuff, I will verify if there is Docker image available. And I will definitely spend more time to discover the possibilities of Docker 🙂
