This image is based on Alpine tomcat image (tomcat:9-alpine), which is only a 75MB image, and provides a docker image for Oracle REST Data Services.

• If you want to build this image, you will need to download Oracle REST Data Services 18.1.1.95.1251 and Oracle SQLcl 18.1.1.

This image is intended to be a base image for your projects, so you may use it like this:

FROM cosmomill/alpine-ords-apex

$ docker build -t my_app . --build-arg ORDS_FILE="ords.18.1.1.95.1251.zip" --build-arg SQLCL_FILE="sqlcl-18.1.1.zip"

$ docker run -d -P --link <your cosmomill/alpine-oracle-xe container>:db --volumes-from <your cosmomill/alpine-oracle-xe container> -v ords_config:/opt -e DATABASE_HOSTNAME="db" -p 8080:8080 my_app

The default list of ENV variables is:

DATABASE_HOSTNAME=
ORACLE_SID=XE
DATABASE_PORT=1521

Auto generated passwords are stored in separate hidden files in /u01/app/oracle/oradata/dbconfig/XE with the naming system .username.passwd.

If you want bootstrap the entire application with a single command using Docker Compose you have to use wait-for-oracle.sh. The problem is that Docker Compose does not wait for the Oracle Database container to become ready before starting the ORDS container. When you start the application using docker-compose up Docker Compose does not ensure that the Oracle Database container is ready before the ORDS Container is started. This means your application will fail to start. The depends_on only means that the Oracle Database container should be started first but Docker Compose does not ensure Oracle Database is full ready for connections. Usage example:

ords:
  depends_on:
    - oradb
  entrypoint: /usr/local/bin/wait-for-oracle.sh -- docker-entrypoint.sh
  command: run
  build:
    context: ./ords
  ports:
    - "8080:8080"
  volumes:
    - ords_config:/opt
  volumes_from:
    - oradb
  environment:
    DATABASE_HOSTNAME: oradb
  restart: always
