How to force pull a docker image from docker hub in azure appservice

Question

I have set up an azure web app service. When trying to pull a private image from Docker Hub, it fails with this error

Pulling image: user/image:latest
2023-01-19T08:05:04.619Z ERROR - DockerApiException: Docker API responded with status code=InternalServerError, response={"message":"Get https://registry-1.docker.io/v2/user/image/manifests/latest: unauthorized: incorrect username or password"}

Ive tried changing the credentials, but cant figure out how to tell the app to try and pull the image again. How can you force the app service to pull the image?

Answer 1

It appears that opening the web SSH (Development Tools -> SSH) forces the webApp to start again and that produces an image pull. I really dont understand how theres no "restart" button

Also, under Deployment -> Deployment center you can grab the webhook URL and do a POST request against it. That will also trigger an image pull
