Oracle Linux base images

This repo stores the architecture-specific rootfs tarballs for the official Oracle Linux base images published on Docker Hub and GitHub Container Registry.

Oracle Linux

Oracle Linux is an open-source operating system available under the GNU General Public License (GPLv2). Suitable for general purpose or Oracle workloads, it benefits from rigorous testing of more than 128,000 hours per day with real-world workloads and includes unique innovations such as Ksplice for zero-downtime kernel patching, DTrace for real-time diagnostics, the powerful Btrfs file system, and more.

How to use these images

The Oracle Linux images are intended for use in the FROM field of a downstream Dockerfile. For example, to use the latest optimized Oracle Linux 7 image, specify FROM oraclelinux:7-slim.

Changelog

Due to the fact that only the latest tarball for each tag is stored in the dist-amd64 and dist-arm64v8 branches, it is not possible to use Git's history to determine what has changed and when. Thus, we maintain a CHANGELOG in the master branch that documents the changes made to various images by date.

Differences between `oraclelinux:7` and `oraclelinux:7-slim`

Oracle recommends using oraclelinux:7-slim as your base layer as it contains just enough packages for yum to work to install more packages. Therefore, it has the smallest size and the least amount of unneeded content.

The oraclelinux:7 images is based off the package set what would be installed via a Minimal install of Oracle Linux.

Differences between `oraclelinux:8` and `oraclelinux:8-slim`

As with Oracle Linux 7, the 8-slim variant contains just enough packages to install more.

However, it also replaces the standard dnf client with the tiny microdnf tool to further reduce space. If you need the functionality of the full client, you can install it via RUN microdnf install dnf in your downstream Dockerfile.

To provide yum compatibility, use RUN microdnf install yum.

Using modules with `microdnf`

An example of how to enable module support when using microdnf can be seen in the oraclelinux:8 variants of the OracleLinuxDeveloper images in the Oracle Docker Images repo.

Finding container images of Oracle products

We provide sample Dockerfiles for several Oracle products in the Oracle Docker Images repository on GitHub. Many of these images are also available for direct download from the Oracle Container Registry.
