Web app - NGINX configuration resets to default

Question

Web app - NGINX configuration resets to default

Nuno Vicente 40

From time to time NGINX is loosing all configurations and resets to default. I'm making the configurations through the SSH terminal.

cp /home/default /etc/nginx/sites-available/default

All goes well for a couple of days and then it goes back to default. Any reason why?

Thanks in advance.

@SnehaAgrawal-MSFT , thank you so much for this. I've made the changes. I will keep an eye on it to really make sure that it's fixed, but I believe so, because I was not using the startup command and it makes all sense to use it. Thank you again for the clear response.

@Nuno Vicente Thanks for reaching here! If I have understood right you want to create your own customized Nginx configuration based on the default one. Please double check on the below steps to be followed.

Copy the default Nginx configuration file located at /etc/nginx/sites-enabled/default to the /home folder.
Since /home files are persisted in Azure Storage, ensure that your custom Nginx configuration file is saved under /home to survive restarts and be shared across instances.
Access the App Service WEBSSH via https://<AppServiceName>.scm.azurewebsites.net/webssh/host.
Modify the Nginx configuration by making changes to the /home/default file.
Use a custom startup script to overwrite the original Nginx configuration file, allowing the platform to use your customized configuration each time the App Service starts.
In the App Service Portal, navigate to "Configuration" -> "General settings" and add the following command in the "Startup Command" field and save the setting. cp /home/default /etc/nginx/sites-enabled/default; service.
