In this post, I’ll share how I set up my local development using Docker and docker . The model must be integrated into the company’s IT infrastructure. You now have a functioning modern stateless API application that can be scaled. Full Title: Deploy Machine Learning Models To Production: With Flask, Streamlit, Docker, And Kubernetes On Google Cloud Platform Publisher: Apress; 1st ed. In your ML model training Python code, you can save your trained and tested ML model (say sgd_clf), using a proper file name, on a file location of your production application server using joblib library of Python, as shown below: In the above command, -d will detach our terminal, -P will publish all exposed ports to random ports and finally --name corresponds to a name we want to give.

This article shows how to containerize Flask and Postgres for local Docker . Deploy Machine Learning Models to Production: With Flask, Streamlit, Docker, and Kubernetes on Google Cloud Platform [1st ed. 4. A trained machine learning model alone will not add value for business. 7-ckt20-1 (released November 2015). To re-iterate with the ps command you can list the docker .
