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.

Azure Container instances
This is the first time i use docker image
when i trying build and upload new version code and push in Azure Container registries
but if i want to apply new version code , i must restart Container instances by manual to apply new version code , it annoys me and is a waste of time
How to resolove auto restart or redeploy when i push new version code in Container registries in Azure ?
this is log deploy azure of myself
I can think of a couple of ways to do this.
AKR Webhooks
I probably will approach this by looking at the webhooks in AKR.
Then, create a Logic App to receive the webhook call when a new image is pushed. References.
In the Logic App, you can call one of the Azure Container Instance APIs to restart the container group.
You will need to consider the security of the Logic App, which can only be called by your AKR's webhook.
CI/CD Pipelines
Assume that you have used a CI/CD platform like Azure DevOps, where you can create build pipelines.
The pipeline can build and push the images to your AKR, then create a step to run Az command to update the instance group.
I probably prefer the pipeline approach as I can see the history of what images have been released on the DevOps page.
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.
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'm having an issue with Azure Container Registry CI with my Azure Web App for Containers. It seems that the web hook between them has broken.
I've tried turning the CI within the Docker settings on the Web App however this fails and also tried creating a web hook from the Azure Container Registry however it says my container registry isn't managed but doesn't give me the option to upgrade it to one.
Webhooks are not available in the classic SKU and you need to migrate for this. For CI you need to enable a webhook with the publishing creds which can call into the App service scm endpoint which can restart and repull.
Through VSTS we have created CI/CD pipeline for a project, in which the end product is a docker image, which will be placed in a azure container registry.
In the azure app service, we have a linux container based service plan, which hosts the above placed latest image.
However, in the docker container, although we have enabled continuous deployment, the latest version is not taken, it is hosting the same older version of image.
How to deploy the latest docker image in app service container ?
Azure Container Registry webhooks can be used to automatically update your application running on Azure App Services that run your container applications.
Setup your image to deploy to your Azure Web App on Linux as per the instruction at https://learn.microsoft.com/en-us/azure/app-service-web/app-service-linux-using-custom-docker-image#how-to-use-a-docker-image-from-a-private-image-registry
In the App Settings section of your Web Application, add an app setting called DOCKER_ENABLE_CI with the value true.
Create a web hook in your registry and provide the docker callback uri which is of the form https://:#.scm.azurewebsites.net/docker/hook
https://:#.scm.azurewebsites.net/docker/hook
