Overview of all OpenML components including a docker-compose to run OpenML services locally

Overview

OpenML Component overview

Prerequisites

Usage

You run all OpenML services locally using 

1
docker compose --profile all up -d
Stop it again using 
1
docker compose --profile all down

Profiles

You can use different profiles:

  • [no profile]: databases
  • "elasticsearch": databases + elasticsearch
  • "rest-api": databases + elasticsearch + REST API
  • "frontend": databases + elasticsearch + REST API + frontend + email-server
  • "minio": database + elasticsearch + REST APP + MinIO + parquet and croissant conversion
  • "all": everything

Usage examples: 

1

3
docker compose --profile all up -d       # all services
docker compose up -d                     # only the database
docker compose --profile frontend up -d  # Frontend, rest-api, elasticsearch and database
Use the same profile for your down command.

Known issues

See the Github Issue list for the known issues.

Debugging

Some usefull commands: 

1

3
docker logs openml-php-rest-api -f              # tail the logs of the php rest api
docker exec -it openml-php-rest-api /bin/bash   # go into the php rest api container
./scripts/connect_db.sql                        # access the database

Endpoints

[!TIP] If you change any port, make sure to change it for all services! The elasticsearch config, for instance, needs to know the port of the frontend (for CORS).

When you spin up the docker-compose, you'll get these endpoints: - Frontend: localhost:5000 - Database: localhost:3306, filled with test data. - ElasticSearch: localhost:9200, filled with test data. - Rest API: localhost:8080 - Minio: console at localhost:9001, filled with test data.

Credentials

The credentials for the database can be found in config/database/.env, for minio in config/minio/.env, etc.

Emails

The email-server is used for emails from the frontend. For example, if you create a new user, an email is send to the user. All outgoing emails are rerouted to catchall@example.com. You can see the messages in config/email-server/messages. Note that some of the urls in the emails need to be slightly altered to use them in the test setup: change https to http.

Development

PHP, Parquet and Croissant converter

If you want to do local development on containers that are part of the docker-compose, you want those containers to change based on your code. You should have the relevant code somewhere on your system, you only need to tell the docker-compose where to find it. You can do so by setting environment variables.

Create a .env file inside this directory, and set:

PHP

1
2
PHP_CODE_DIR=/path/to/OpenML                  # Root of https://github.com/openml/OpenML on your computer
PHP_CODE_VAR_WWW_OPENML=/var/www/openml       # Always set this to /var/www/openml. Leave empty if you leave PHP_CODE_DIR empty

Make sure to create openml_OS/config/BASE_CONFIG.php in your local $PHP_CODE_DIR. The correct configuration can be found in config/php.env. Run docker compose with profile rest-api.

Parquet

ARFF_TO_PQ_CODE_DIR=/path/to/minio-data       # Root of https://github.com/openml-labs/minio-data on your computer
ARFF_TO_PQ_APP=/app                           # Always set this to /app. Leave empty if you leave ARFF_TO_PQ_CODE_DIR empty

Croissant

2
CROISSANT_CODE_DIR=/path/to/openml-croissant/python  # Python directory of https://github.com/openml/openml-croissant on your computer
CROISSANT_APP=/app                                   # Always set this to /app. Leave empty if you leave CROISSANT_CODE_DIR empty

Frontend

1
2
FRONTEND_CODE_DIR=/path/to/openml.org        # Python directory of https://github.com/openml/openml.org on your computer
FRONTEND_APP=/app                            # Always set this to /app. Leave empty if you leave FRONTEND_CODE_DIR empty

Other services

If you want to develop a service that depends on any of the services in this docker-compose, just bring up this docker-compose and point your service to the correct endpoints.
