Install Oracle Instant client into Docker container for Python cx Oracle

Installing Oracle Instant Client into a Docker container for Python cx_Oracle involves a few steps, including setting up the Oracle Instant Client, configuring the environment variables, and installing the cx_Oracle Python package. Below is a step-by-step tutorial with code examples.
Create a Dockerfile to build your Docker image. You can use the official Oracle Linux base image and install the Oracle Instant Client on top of it.
Visit the Oracle Instant Client download page and download the Basic and SDK packages for Linux x86-64. Save these files in the same directory as your Dockerfile.
Navigate to the directory containing your Dockerfile and the downloaded Instant Client files. Build the Docker image using the following command:
Once the image is built, you can run a container based on the image:
This will start the container, and if you've included a Python script, it will be executed.
Replace placeholders like 'your_username', 'your_password', 'your_service_name', and 'your_table' with your actual Oracle database information.
This tutorial provides a basic setup for running Oracle Instant Client with cx_Oracle in a Docker container. Adjustments may be needed based on your specific project requirements and Oracle configurations.
