azure-functions-app-container.yml

# This workflow will build a container and deploy it to an Azure Functions App on Linux when a commit is pushed to your default branch.
#
# This workflow assumes you have already created the target Azure Functions app.
# For instructions see https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-function-linux-custom-image?tabs=in-process%2Cbash%2Cazure-cli&pivots=programming-language-csharp
#
# To configure this workflow:
# 1. Set up the following secrets in your repository:
#   - AZURE_RBAC_CREDENTIALS
#   - REGISTRY_USERNAME
#   - REGISTRY_PASSWORD
# 2. Change env variables for your configuration.
