Azure Functions

We used Azure Functions to react or trigger events (functions) for some tasks, namely:

• Getting forex exchange data from (central) banks and storing them in the database.
• When creating real estate posting, user can send pictures via email (instead of uploading them).
• See GitHub issue for more ideas.

Consumption plan should be enough. Though a premium plan, which enables to use full docker images, can be better due to large Python3 dependencies.

Our Branch

The branch with Azure functions: azure-functions, see link here.

Build

Sources:

• https://docs.microsoft.com/de-de/azure/azure-functions/functions-reference-python

• https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-function-linux-custom-image

1. Pyenv

Use pyenv in this worktree. Execute in the root:

Be careful on using VSCode with Python/"Live autocompl." plugins as VSCode will inevitably crash.

git switch azure-functions
pyenv install 3.6.9 # Azure is currently compatible only with Python 3.6
pyenv local 3.6.9

2. Start Docker and Build Dockerfile

sudo systemctl start docker
func azure functionapp publish django-wohn --build-native-deps
