⚠️ Please, use one of the official images instead ⚠️

This repo contains a Dockerfile to create an image with Oracle Database 11g Express Edition running in CentOS 7

The main reason for this repo is to have clean and transparent Dockerfile, without any magic behind. It is based on official CentOS images and the build is completely described in the Dockerfile. Unlike many other images on the Net this one uses stock rpm installer provided by Oracle, not repacked by alien.

Let's assume that you are familar with Docker and building Docker images from Dockerfiles.

1. Download the rpm installer.

2. Unzip it and pack oracle-xe-11.2.0-1.0.x86_64.rpm in tar.gz archive named oracle-xe-11.2.0-1.0.x86_64.rpm.tar.gz so that it's contents look like:

    % tar -tf oracle-xe-11.2.0-1.0.x86_64.rpm.tar.gz
    oracle-xe-11.2.0-1.0.x86_64.rpm
   

3. Place the tarball inside the rpm directory of this repo.

4. Run docker build -t "madhead/docker-oracle-xe" . from the root directory of this repo.

5. You should get your image ready in a few minutes (apart from downloading base centos:centos7 image).

During the configuration of Oracle XE instance two files - init.ora and initXETemp.ora - are overridden with ones from config directory of this repo. The only difference is that memory_target parameter is commented in them to prevent ORA-00845: MEMORY_TARGET not supported on this system error. The only piece of magic in this image :).

Basically docker run -p 8089:8080 -p 1521:1521 -d madhead/docker-oracle-xe will start new container and bind it's local ports 1521 and 8080 to host's 1521 and 8089 respectively. Read Docker documentation for details.
