Web App Deployment Center seems to have randomly enabled side car support

I have been working on an app for the past couple of weeks using a single container without sidecar in two deployment slots. Today, when I look at my deployment centre, I have lost the Settings option, and now have "Containers" which makes it seem like the web app deployment now includes side car support.

Production Deployment Center

If I look at the development deployment slot, I still see the original settings, with registry and image options.

Development Deployment Center

As I did not request sidecar support, can I turn it off?

And is there a reason this is happening?

    Hi Nkechi Achara,

    • Currently, you cannot manually disable the sidecar container feature in the updated UI. Azure has moved into an integrated container experience where the sidecar support is part of the base configuration.
    • However, you can safely continue to use it as a single-concenter finale, and everything should still work expected. As long as you clearly add additional containers, you do not need to configure or use sidecars.
    • If you want to maintain the original signs (without "containers" tabs), there are some options:
    • Create a new app service plan / web app in the area where the update has not been rolled out yet. (This is a hit-or-mise due to a gradual rollout.)
    • Continue using the existing growth slot for image/registry-based changes-because it still supports the old UI.
    • Use Azure CLI or Arm Template to manage your deployment, allowing you complete control over the configuration without relying on UI.
