rdb

Repository of Docker Images for testing database packages, including dm.

Overview

Testing an R package that connects to a database can be a challenge. The package must be tested against different databases, different versions of the same database, and different operating systems. This can be a time-consuming process, especially if you don't have access to a database server.

This repository offers a solution based on Docker Compose. Docker images are defined for each component and for each database. A hierarchy of Docker Compose files helps combine the components and databases to run tests without altering the development environment.

Databases Covered:

• Microsoft SQL Server: developed by Microsoft.
• MySQL: developed by Oracle, open-source.
• MariaDB: developed by MariaDB Corporation Ab, open-source.
• Oracle Database Free: developed by Oracle.
• Oracle Database Express Edition: developed by Oracle.
• PostgreSQL: developed by PostgreSQL Global Development Group, open-source.
• SQLite: developed by D. Richard Hipp, open-source, file-based, and designed to be embedded into applications.
• DuckDB: developed by the CWI Database Architectures group, open-source.
• ADBC is a developing open-source standard designed to facilitate database interactions using the Apache Arrow framework.

Development

The main docker-compose.yml merely includes files in docker-compose/ . For new services, create a new file.

Pull all images

docker-compose pull

Pull individual images

Example: pull images necessary to run tests against Oracle.

docker-compose pull oracle rdb_oracle
