I created Azure App Service. I choosed "single container" and used "Private Registry".
I filled my private docker hub, credentials, username & password and my site is running my docker image website well.
Now I want to use NEW image with newer tag. I noticed, there is a "webhook" functionality but I dont know how to use this webhook. I thing, that this webhook can be used to pull newer image from my registry but I dont know how to use it.
If this is not the meaning of this web hook, what is the best practise to PULL new container to web app service.
Note: I am not using Azure Container registry. I have my own private hub. And I want to use Jenkins to deploy new container.

I have a pipeline that publishes to my private Azure container registry but if I push a new image tagged with latest, my Azure app service does not pull the newly tagged latest image. I have Continuous deployment turned on via the DOCKER_ENABLE_CI app setting.
Additionally, I'm using a managed identity to authenticate with the ACR. I feel like the CD portion was working when I was using credentials to pull the image but after switching to managed identity it appears to have stopped. In order to get the new image I have to restart the app service which is not idea and makes this CD option useless...
When you enable Continuous deployment, App Service adds a webhook to your ACR to notify the web apps. The webhook causes your App Service app to restart and run the docker pull to get the updated image.
So, please go to your ACR, and under webhook, please check if there are running webhooks or not, if not you can create a webhook manually and see if the WebApp get the latest image in the following deployment.

When I google this every result is a microsoft document describing how to bring code INTO Azure. But I am looking for a way to take an existing Azure app service and make a docker image of it and then deploy that onto my own server.
Is this possible?
I believe Azure provides a mechanism to generate the docker image. Is that all I need?
We have a requirement, where we publish a docker image, and a client through an automation workflow tool such as Logic App pull down a docker image and upload it to an Azure App Service instance. Is #2, #3 achievable via some from of RESTFul API?
We publish an image into docker hub
Client runs a process to
pull this image down via HTTP request
And upload it to an
instance of an Azure app service via HTTP Request
I found this : https://docs.docker.com/registry/spec/api/#pulling-an-image just unsure if this is useful in the sense where we need to deploy this image to an Azure App Service instance and let it run the image?
You don't download an image from a container registry and upload it to App Service, you need to update the App Service configuration and App Service will pull the image. You can do this using the Azure CLI:
az webapp config container set --docker-custom-image-name org/hello-app:1.0 --name demoforharry --resource-group demo
Documentation
If you want to use HTTP, I guess that you can also use the Azure Management API.

We use Web App for Containers to operate Docker containers hosted on our Azure registry. This web app has been configured to pull the latest changes from the registry which in turns has lead to the creation of the following env variables:
DOCKER_REGISTRY_SERVER_URL
DOCKER_REGISTRY_SERVER_USERNAME
DOCKER_REGISTRY_SERVER_PASSWORD
DOCKER_ENABLE_CI
All values are correct and in the first place the Docker based setup worked well for us. Since monday, however, Kudu is longer able to pull docker images from our registry (neither from any registry that requires auth at all). The Kudu log is:
docker pull returned STDERR>> Error response from daemon: Get OUR_REGISTRY: unauthorized: authentication required
which suggests that Kudu is omitting the required Docker login call. Has anyone observed the same behaviour or is aware of Azure changes that require any adoption form our site. Thanks!
What we have tried so far:
creating a new registry
creating a new web app
creating a new service plan
restarting/stopping the web apps
I have setup an Azure App Service to host a docker container. This is all running fine -- pointing at a private Docker repository/image, using the latest tag.
I would like to be able to publish a new Dockage image from my CI server to the Docker repository under the latest tag and somehow trigger the App Service to pick up that there is a change of the latest image.
It seems I can trigger the change by modifying an Application Setting on the App Service and saving it -- but this does not seem like the correct way to handle it.
Is there a best practise for this kind of deployment?
In the properties section of the web app you'll find a DEPLOYMENT TRIGGER URL.
This URL should point to the /deploy endpoint. Remove that part and use the /docker/hook endpoint.
Your URL should look something like this: https://xxxx.scm.azurewebsites.net/docker/hook
If you POST to that URL with empty body it will trigger a deployment using the latest docker image.
Currently they are working on a solution for this scenario but as stated in their FAQ about Web App on Linux either modifying the application settings or restarting the web app is the only way of triggering the change.
