DISCLAIMER: dama is currently in alpha due to the lack of security and scaling, but still fun to try out!

Server Configuration

Server default configurations in config.yml These configurations are loaded by default if not overridden in config.yml.

expire: "1300"
deployexpire: "86400"
uploadsize: 2000000000
envsize: 20
  listen: ""
  port: "8443"
  debug: false
  verifytls: false
  db: 0
  maxretries: 20
  endpoint: "unix:///var/run/docker.sock"
  cpushares: 512
  memory: 1073741824
  tls: false

These configurations need to be set in your environment variables.

# Server admin username and password
DamaUser       # example: DamaUser="tim"
DamaPassword   # example: DamaPassword="9e9692478ca848a19feb8e24e5506ec89"

# Redis database password if applicable
DBPassword     # example: DBPassword="9e9692478ca848a19feb8e24e5506ec89"

All configurations types

dama.yml File

This a simple dama.yml to setup your environment and run a Flask API.

image: "taskfit:minimal"
port: "5000"
pip: |
python: |
  from flask import Flask, request, jsonify
  from sklearn import datasets
  from sklearn.model_selection import train_test_split
  from sklearn.ensemble import RandomForestClassifier
  from sklearn.externals import joblib

  X, y = datasets.load_iris(return_X_y=True)
  X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=42)
  model = RandomForestClassifier(random_state=101), y_train)
  print("Score on the training set is: {:2}".format(model.score(X_train, y_train)))
  print("Score on the test set is: {:.2}".format(model.score(X_test, y_test)))
  model_filename = 'iris-rf-v1.0.pkl'
  print("Saving model to {}...".format(model_filename))
  joblib.dump(model, model_filename)
  app = Flask(__name__)
  MODEL = joblib.load('iris-rf-v1.0.pkl')
  MODEL_LABELS = ['setosa', 'versicolor', 'virginica']

    def predict():
      sepal_length = request.args.get('sepal_length')
      sepal_width = request.args.get('sepal_width')
      petal_length = request.args.get('petal_length')
      petal_width = request.args.get('petal_width')
      features = [[sepal_length, sepal_width, petal_length, petal_width]]
      label_index = MODEL.predict(features)
      label = MODEL_LABELS[label_index[0]]
      return jsonify(status='complete', label=label)
  if __name__ == '__main__':, host="", threaded=True)

cURL API in sandbox or deploy

curl -ks https://localhost:8443/api/<insert sandbox key>/predict?sepal_length=5&sepal_width=3.1&petal_length=2.5&petal_width=1.2

Even simpler environment setup with model training.

To Do

  • Tokenize environment variables in DB
  • Write test suite
  • Provide Vagrant and Docker images
  • Add scheduler / resource manager for multi-host container serving
  • Rewrite auth middleware
  • Swap out stdlib flags package for third-party package
  • These docs stink!
You can’t perform that action at this time.
