An AZD Template for a Chainlit Azure Container App

An AZD Template for a Chainlit Azure Container App Late last year I was looking for an AZD template that uses Chainlit for a UI application and deploys to Azure Container Apps, but couldn’t find one … so now I’m working on building one. Chainlit OpenAI AssistantsAPI Azure Container Apps Starter This is a starter template that works with Azure Developer CLI (AZD) to create a Chainlit application and deploy it to Azure in a matter of minutes. The application code currently uses OpenAI and OpenAI Assistants API - I’m working on adding more functionality to it soon. The GitHub repository is here: chainlit-openai-assistantsapi-aca-starter. I’ve got the windows version of the README instructions out there, but haven’t updated the local environment steps for …

How to set environment variables in a Container App using the Azure CLI

Last month when I presented on Azure Container Apps, I was asked “How would you set an environment variable?”. Since it isn’t currently surfaced in the Azure Portal, I wasn’t sure. Container Apps is still in preview and right now the best way to access the largest amount of features is by using ARM or Bicep … but since it is new a lot of people start with the Portal or the Azure CLI to explore. In this short post, I want to capture how I should have answered the question during my demo. How can I pass environment variables to a Container App? If you look through the documentation, you can find an exmple of environment variables being set in the Manage Secrets Example page. In that example they are focusing on secrets, but since secrets get surfaced in the …

How to rollback a Container App revision

Last week I presented “A look at Azure Container Apps” to our local Azure user group. I was my first time presenting the topic and I’ll just say it wasn’t my best presentation (believe me - I’ve watched the whole recording). But anyway … during one of the demos a question came up about if it was easy to rollback a revision. I attempted to do perform a demo of how to do it, but the demo gods were not helping me last Thursday night. Today at lunch I tried it again, and of course it worked fine. This is a walkthrough of how it should have worked last week. Prerequisite for this walkthrough is to follow the steps in the Deploy your first container app (Azure Portal), but insert the following steps before the last Clean up resources step. Rollback a …
