Building an Internal App to Track 1,200+ VMs and Servers at REI
Manage episode 288661598 series 2589818
In this episode of Running in Production, Sean Callaway talks about building an app to help manage REI’s server infrastructure. It was built with Django and it’s mostly hosted on premises in their own data center.
Sean covers keeping the app mostly server rendered and goes into detail about using Ansible, Kubernetes and Rancher to help manage things.
Topics Include
- 4:16 – Motivation for using Django and Python
- 6:27 – The Django admin is not being used
- 8:20 – Using Ansible to automate spinning up VMware based VMs
- 10:17 – It’s a monolithic application and it does use Django apps
- 12:14 – A high level overview of what the app does to help visualize it
- 15:14 – It’s using Django templates and they tuned a few database queries
- 18:19 – PostgreSQL is used for some data and maybe Celery will be used soon
- 21:07 – nginx is serving static files and Kubernetes’ ingress controller handles SSL certs
- 23:43 – Docker Compose is being used in dev and what Kubernetes has been like so far
- 28:42 – Pretty much all of their servers are hosted on premises
- 31:17 – Using Grafana, Splunk and Prometheus for logging and monitoring
- 34:26 – For the Linux servers, they’re running CentOS with Rancher
- 38:50 – The entire flow for pushing code from development to production
- 45:37 – Database backups and planning for disasters
- 51:50 – Best tips? Containerize your app quickly
- 55:05 – You can find Sean on GitHub, Twitter and he has a blog at https://callaway.dev

This episode does not have a sponsor and this podcast is a labor of love. If you want to support the show, the best way to do it is to purchase one of my courses or suggest one to a friend.
- Dive into Docker is a video course that takes you from not knowing what Docker is to being able to confidently use Docker and Docker Compose for your own apps. Long gone are the days of "but it works on my machine!". A bunch of follow along labs are included.
- Build a SAAS App with Flask is a video course where we build a real world SAAS app that accepts payments, has a custom admin, includes high test coverage and goes over how to implement and apply 50+ common web app features. There's over 20+ hours of video.
