THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

Install MADlib by following the steps in the Installation Guide for MADlib or use the Docker image instructions below.
MADlib source code is organized such that the core logic of a machine learning or statistical module is located in a common location, and the database-port specific code is located in a ports folder. Since all currently supported databases are based on Postgres, the postgres port contains all the port-specific files, with greenplum and hawq inheriting from it. Before proceeding with this guide, it is recommended that you familiarize yourself with the MADlib module anatomy.

We provide a Docker image with necessary dependencies required to compile and test MADlib on PostgreSQL 9.6. You can view the dependency docker file at ./tool/docker/base/Dockerfile_postgres_9_6. The image is hosted on docker hub at madlib/postgres_9.6:latest. Later we will provide a similar Docker image for Greenplum Database.
Some useful commands to use the Docker file:
| Code Block |
|---|
## 1) Pull down the `madlib/postgres_9.6:latest` image from docker hub:
docker pull madlib/postgres_9.6:latest
## 2) Launch a container corresponding to the MADlib image, mounting the source code folder to the container:
docker run -d -it --name madlib -v (path to incubator-madlib directory):/incubator-madlib/ madlib/postgres_9.6
where incubator-madlib is the directory where the MADlib source code resides.
############################################## * WARNING * ##################################################
# Please be aware that when mounting a volume as shown above, any changes you make in the "incubator-madlib"
# folder inside the Docker container will be reflected on your local disk (and vice versa). This means that
# deleting data in the mounted volume from a Docker container will delete the data from your local disk also.
#############################################################################################################
## 3) When the container is up, connect to it and build MADlib:
docker exec -it madlib bash
mkdir /incubator-madlib/build-docker
cd /incubator-madlib/build-docker
cmake ..
make
make doc
make install
## 4) Install MADlib:
src/bin/madpack -p postgres -c postgres/postgres@localhost:5432/postgres install
## 5) Several other madpack commands can now be run:
# Run install check, on all modules:
src/bin/madpack -p postgres -c postgres/postgres@localhost:5432/postgres install-check
# Run install check, on a specific module, say svm:
src/bin/madpack -p postgres -c postgres/postgres@localhost:5432/postgres install-check -t svm
# Reinstall MADlib:
src/bin/madpack -p postgres -c postgres/postgres@localhost:5432/postgres reinstall
## 6) Kill and remove containers (after exiting the container):
docker kill madlib
docker rm madlib |
