FROM python:3.7-slim
RUN pip install numpy scipy pandas sklearn
ENV APP_HOME /app
WORKDIR $APP_HOME
COPY . ./
CMD python sample.py

import numpy as np
import os
from sklearn.linear_model import LogisticRegression
from sklearn.pipeline import Pipeline
from sklearn.externals import joblib
from sklearn import datasets

def main():
    clf = LogisticRegression()
    p = Pipeline([('clf', clf)])
    print('Training model...')
    p.fit(X, y)
    print('Model trained!')

    filename_p = 'IrisClassifier.sav'
    print('Saving model in %s' % filename_p)
    joblib.dump(p, filename_p)
    print('Model saved!')

if __name__ == "__main__":
    print('Loading iris data set...')
    iris = datasets.load_iris()
    X, y = iris.data, iris.target
    print('Dataset loaded!')
    main()
