I am not able to deploy registry image to Azure Kubernetes
i have one image name hello-world in azure container registry .Now i want this image will be manages by Kubernetes service .
i follow this link here
but not able to understand manifest file and how i generate "yml" file
i pull image from docker registry and push to private container registry .Now my images are kept in azure container registry .Now i want to deploy to AKS from conatiner registry .But how i do this.
From the docs
Establish an authentication mechanism between AKS and ACR
Ensure you have the proper AKS credentials using az aks get-credentials -g myResourceGroup -n myAKSCluster
Apply the kubernetes deployment yaml to AKS

my scenario is like I have shared container registry in one subscription say subscription A, I need to pull image from ACR to ACA through DevOps pipelines. The ACAs are present for each environment like dev, test, UAT & etc which is in another subscription say subscription B. I am using 'az containerapp up' command in azure devops pipelines to pull image of the shared ACR. Getting error 'The resource is not found in the subscription B'. What might be the alternative possible solution because we need to reduce cost of using container registry for each environment.
I am using service connections to pull image and the service connections are separate for separate subscriptions.
I know that they are in different subscriptions but I searched on websites to connect two different subscriptions.
Is there a possibility that I can connect two different service connections in azure devops & use one service connection to pull that image.
Before integrating the Azure CLI command az containerapp up with Azure pipelines, please first confirm you are able to pull the ACR image from Sub B to deploy the container app in Sub A via CloudShell or LocalPowerShell.
I tested to create ARM service connection with Tenant Root Management Group whose referenced service principle had access to both subscriptions; the issue still existed.
In local PowerShell, I az login with my user account and still could reproduce the issue.
az containerapp up `
--name XXcontainerapp `
--image XXacrsubB.azurecr.io/azurecontainerappdemo:XX `
--resource-group rg-containerapp `
--environment TestEnv `
--registry-username XXacrsubB `
--registry-password XXXXXX
It seemed to be a limitation with this command az containerapp up. You may consider reporting the issue with Azure CLI.
I'm trying to Connect a Azure Webb app (containers) to an Azure Container Registry Using the Azure CLI. I have an Azure Container Registry located in the same Ressouce Group as the Webb App.
My command looks like this:
az webapp config container set --name "containerbugdemo" --resource-group "Containerbug" --docker-custom-image-name "application/helloworld:latest" --docker-registry-server-url "https://"$arcName.azurecr.io" --docker-registry-server-password "****" --docker-registry-server-user "***"
After running the command the container settings blade shows the following error:
Failed to get a list of tags.
And the Container fails to get pulled by the WebApp.
If I try the same procedure only using the graphical interface through the Azure portal, everything works as expected.
It seems you set the wrong image name. If you use the image in the ACR, you need to set the image name as acrname.azurecr.io/repository:tag, both when you create the web app and container setting, not just repository:tag. And the server URL is also a mistake that one more double quote in the question.
I am creating azure webapp (multi container app) using CLI. My docker images are in azure container registry(ACR). how do i pass my registry credentials to it or pass some flag that it recognise that images need to be pulled from ACR.
here is my command running from my linux machine (logged in with az login)
az webapp create --resource-group RishiCTS --plan rishi-kpi --name rishi-models --multicontainer-config-type compose --multicontainer-config-file docker-compose-models.yml
update: In azure portal I can pass docker-compose and select image source as ACR, but this start only first service from docker-compose.
You just need to set the image in the YAML like this:
image: myregistry.azurecr.io/image:tag
Then the Web App will pull the image from your Container Registry. You can take a look at the example for multiple containers. And then you need to add the credential of the ACR with the environment variables:
DOCKER_REGISTRY_SERVER_USERNAME - The username for the ACR server.
DOCKER_REGISTRY_SERVER_URL - The full URL to the ACR server. (For
example, https://my-server.azurecr.io.)
DOCKER_REGISTRY_SERVER_PASSWORD - The password for the ACR server.

A few weeks ago, I was able to use the Azure CLI to create my Container Registry (ACR) and Kubernetes (AKS) cluster. I could push images to my ACR and have AKS pull images successfully - everything worked great. Every now and then, I would have to refresh my login with az acr login --name <acrName>, but not a big deal.
Today, I found that when I go to deploy an updated image to my AKS cluster, I got a status of ImagePullBackOff:
Failed to pull image "MY_ACR.azurecr.io/MY_IMAGE:v1": rpc error: code = Unknown desc = Error response from daemon: Get https://MY_ACR.azurecr.io/v2/MY_IMAGE/manifests/v1: unauthorized: authentication required, visit https://aka.ms/acr/authorization for more information.
I couldn't remember what I needed to do to make this work, so I went through my original steps and created an entirely new resource group, ACR, AKS cluster, and service principal connecting them. I pushed images to my ACR and was able to apply my Kubernetes manifest, and everything worked again.
A couple hours later, when I applied an updated manifest, I again got the same error message. As part of my setup, I created a service principal:
az ad sp create-for-rbac --skip-assignment
az role assignment create --assignee <principal's appId> --scope <my ACR's id> --role Reader
I also used --role acrpull. It seems like the authentication has timed out, and the documentation for Authenticate with an Azure container registry says that individual AD identities will time out after 3 hours, but even after running az acr login --name <acrName>, I'm not able to fix the issue.
What are the required steps to get my AKS cluster to be able to authenticate again to my ACR?
I'll note that I also attached the ACR according to the documentation at Authenticate with Azure Container Registry from Azure Kubernetes Service by running:
az aks update -n cluster_name -g resource_group --attach-acr acr_name
I also tried using the ACR id instead of the name. After a minute or so, the command completed, and even a half hour+ later, I get the same permissions issue.
The easiest way to integrate AKS with ACR is to leverage the --attach-acr option during cluster creation. This will have AKS manage the service principal for your and handle the token refresh's

I'm trying to follow this guide to setting up a K8s cluster with external-dns' Azure DNS provider.
The guide states that:
When your Kubernetes cluster is created by ACS, a file named /etc/kubernetes/azure.json is created to store the Azure credentials for API access. Kubernetes uses this file for the Azure cloud provider.
When I create a cluster using aks (e.g. az aks create --resource-group myResourceGroup --name myK8sCluster --node-count 1 --generate-ssh-keys) this file doesn't exist.
Where do the API credentials get stored when using AKS?
Essentially I'm trying to work out where to point this command:
kubectl create secret generic azure-config-file --from-
file=/etc/kubernetes/azure.json
From what I can see when using AKS the /etc/kubernetes/azure.json doesn't get created. As an alternative I followed the instructions for use with non Azure hosted sites and created a service principal (https://github.com/kubernetes-incubator/external-dns/blob/master/docs/tutorials/azure.md#optional-create-service-principal)
Creating the service principal produces some json that contains most of the detail. This can be used to manually create the azure.json file and the secret can be created from it.
Use this command to get credentials:
az aks get-credentials --resource-group myResourceGroup --name myK8sCluster

Did you try this command ?
cat ~/.kube/config
It provided all i needed for my CI to connect to the Kubernetes Cluster and use API
