A while ago I needed to change an Azure Function timeout but I wanted to avoid, if possible, to republish it. After a little while searching I discovered this page which explain how to overwrite the values specified in the host.json file with the values specified from the Azure configuration.
The article states that if you specify a configuration value in the following format:
AzureFunctionsJobHost__path__to__settingThe runtime will replace the existing value of the path.to.setting with the one specified.
Note that the dot (.) in the setting name must be expressed as double underscore (__) when specifying the setting in the Azure configuration.
In my case I wanted to override the value of the function timeout to 1 hour so I added the following to the Azure Function configuration in the Azure portal:
AzureFunctionsJobHost__functionTimeout: 01:00:00Hope this helps!
