Containerize your Db2 Python app

De-containerizing my stuff
By following my blog posts (here or at the IBM Cloud site)  or my code samples, you might know that many of my apps are coded in Python. Moreover, many projects involve IBM Db2 (see "How to connect from Python to Db2"). With Docker and other container technologies around and many projects involving Kubernetes / OpenShift or Knative / IBM Cloud Code Engine, the next question is how to containerize / dockerize your Db2 application written in Python. Well, here I share some of my experience...

Some fun with traefik routing on the edge of a reverse proxy

Path-based routing with Traefik

In a recent blog post, I mentioned that I use the traefik edge router / reverse proxy to put a custom domain in front of my IBM Cloud Code Engine apps. Today, I want to share details on how I configured path-based routing, i.e., depending on the path in the URI a different Code Engine app serves the request. The use case is to implement a microservices-based solution architecture with multiple backend services reachable over a single host name (on a custom domain).

A simple nginx deployment on IBM Cloud Code Engine

HTML files as configmap in Code Engine
Over the weekend I deployed nginx on IBM Cloud Code Engine. It's nothing fancy or earth-moving. But I wanted to note down and share the steps with you on how to deploy this HTTP server and serve few static HTML pages. All is based on using the command line interface (CLI) and is done with few commands.

Custom domain for your serverless Code Engine app

Output of a IBM Cloud Code Engine app
A custom domain, e.g. somethin like, always puts a nice touch on an app. Often, it is required for corporate identity. Still, not all services offer that capability. As written, I recently migrated some apps from Cloud Foundry to IBM Cloud Code Engine. Right now, Code Engine does not support custom domains out of the box, but I heard that it is planned. Thus, I looked into temporary workarounds for using a custom domain name for my serverless Code Engine apps.
