I tried on-premises synchronizes container images by using Connected Registry in Azure Container Registry.
And I followed ACR documentation to create a setup (https://learn.microsoft.com/en-us/azure/container-registry/quickstart-deploy-connected-registry-iot-edge-cli)
Getting error while deploying the modules
Troubleshoot - Container Log
ACR Token Details
ACR Scope Details
getting insufficient scope error. But I gave ReadWrite permission for all the repositories. Is there any other way to solve this issue?
Please check if you have given the permissions content/read , content/write scopes for the required registry for repository push , which I hope you have already done if the repo is present.
If the permissions are configured properly , please check if the admin user is enabled .
The scopes may also refer to the actual role permission to operate
For the Azure Container Registry, you may log in in two ways.
One - Using the command az acr login -n azureacrServer -u username -p password. Then you have the owner permission after logging in.
The other one is that log in with a service principal using the command docker login azureacrServer -u servicePrincipalId -p sppassword. In this way, you just have the permission of the service principal after logging in
Please check
Registry authentication options and container registry repository scoped permissions

I have created an Azure Container Registry.
I have an Azure DevOps project.
I have created an Azure DevOps Pipeline using the wizard so
that it uses the standard template to build and push a Docker image.
When validating the Pipeline the following error is thrown:
Failed to set Azure permission 'RoleAssignmentId: ****' for the service principal '****' on subscription ID '****': error code: Forbidden, inner error code: AuthorizationFailed, inner error message The client '****' with object id '****' does not have authorization to perform action 'Microsoft.Authorization/roleAssignments/write' over scope '/subscriptions/****/resourceGroups/****/providers/Microsoft.ContainerRegistry/registries/****/providers/Microsoft.Authorization/roleAssignments/****' or the scope is invalid. If access was recently granted, please refresh your credentials. Ensure that the user has 'Owner' or 'User Access Administrator' permissions on the Subscription.
What configuration could I be missing? The documentation for this is all very sparse and written as though it should all just work.
Thanks
You need to add AcrPull permission to service principal you used here. Please got to you ACR and add it.
Here you have id of you service principal:
Failed to set Azure permission 'RoleAssignmentId: ' for the service principal ''
Also please check also networking on ACR if it blocks you or not.
To build and push your Docker image in Azure pipeline, you need follow the steps below:
Navigate to Project Settings > Service connections to create a Docker Registry service connection that can connect to your ACR.
In the pipeline, add the Docker task to build and push your Docker image to ACR.
Yours service principal on service connection is missing permissions link to documentation https://learn.microsoft.com/en-us/azure/container-registry/container-registry-roles?tabs=azure-cli. You can use custom role or build like contributor on resource group level. Example of custom role and allowed actions "Microsoft.ContainerRegistry/registries/push/write",
I have successfully created a docker image that runs inside a docker container. The container successfully executes the image (a .NET app) but the image crashes shortly after startup because it encounters an error with Azure Services. The reason is because the docker container is attempting to access Azure Services to fetch an authorization token (to fetch secrets from a key vault) and does not have authority to do so.
I should note that it is possible to run the app locally outside of a container via the Azure CLI after using az login to verify my credentials. Then, when the app is started via Azure CLI, it is 'allowed' to access Azure Services to get autho tokens and consequentially fetch data from my key vault.
Would like to know if there is a way to run an az login script with credentials inside a docker container before the .NET app image executes, so that I can start the application from within the Azure CLI (inside the container) after my credentials have been verified. I have looked through the documentation and have not seen a way to configure something like this.
To use the Azure CLI and login inside the container, you need to install the Azure CLI inside the container, then login with an non-interactive model. I would recommend the service principal. You can take a look at the command:
az login --service-principal -u <app-url> -p <password-or-cert> --tenant <tenant>
For more details, see Create an Azure service principal with Azure CLI. After login, then you can start your application as need.
Here are 2 options which don't require Azure CLI in the container, Azure Managed Identity from within a docker container running locally,
inject an access token into the container using ENV variable
use device authentication flow to obtain an access token
I read this answers a while ago. I was looking for the similar solution but using the service principal. I found that Docker can run Kubernetes and there is AAD-Pod-Identity https://github.com/Azure/aad-pod-identity which can do work for me, but it doesn't work for Docker Kubernetes. I forked their Go repository and make modification for mic component. Now it works for Docker Kubernetes, not sure whether Azure team has plans get these modifications on board or not.
You can get detailed instructions how to get things running here: https://github.com/Wallsmedia/aad-pod-identity
Azure CLI would not work for a Docker, because you have setup Azure CLI and login and then run your application.
In production we use Azure Container Registry and AKS. For development, we have K3s on our dev server (on-prem). Is it possible for K3s to pull images from a private registry such as Azure Container Registry?
The short answer is Yes, even if the Azure Container Registry is a private registry, but if you have the username and password with the right permissions, then you can pull the image in it via the username and password. You can take a look at the steps in Azure Container Registry authentication with service principals.
I want to use a Azure Container Registry of a different account in a Build pipeline in Azure DevOps.
When I try to add a Docker Registry Service Connection and select Azure Container Registry, it only lets me choose between the subscription of the current account.
When I try to add the Azure Resource Manager of the Subscription of a different account which contains the Azure Container Registry in the Service Connections, it says it cannot find any Azure Container Registry.
So how do I accomplish this?
I have the same situation in which the Azure Container Registry (ACR) is in a different Azure AD from the Azure DevOps build pipelines.
I'll outline the steps I used:
Create an app registration in the Azure AD where the ACR exists.
Give it a name like myregistry-app
Go to the myregistry-app Certificates and secrets page and create a new secret. Copy the value as you cannot retrieve it later.
Also copy the myregistry-app application id. You can find it on the overview screen.
Now go to the ACR Access Control (IAM) screen for your container registry.
Add a role assignment and assign the myregistry-app identity the Contributor role.
Back in your build pipeline create a Docker task and click on the New button under the Container Registry section.
In the popup dialog Add a Docker Registry service connection choose the Others radio button.
Put in the URL to your ACR which you can find on the container registry overview page.
Use the application id for myregistry-app as the Docker ID.
Use the myregistry-app secret for the password.
This is currently working for me. There may be a better way
I log in successfully, but cannot pull:
PS C:\Users\Me> docker login tlk8s.azurecr.io
Username (myUsername): Password:
Login Succeeded
PS C:\Users\Me> docker pull tlk8s.azurecr.io/devicecloudwebapi:v1
Error response from daemon: pull access denied for tlk8s.azurecr.io/devicecloudwebapi, repository does not exist or may require 'docker login'
But it seems like I'm naming it correctly (see screenshot):
What could I be doing wrong? How do I check to see if my service principal has the correct permissions?
Here's the result of calling Get-AzureRmRoleAssignment:
Per documentation below, the Service Principal account must have at least Reader role to be able to pull images from the Azure Container Registry.
https://learn.microsoft.com/en-us/azure/container-registry/container-registry-authentication
You can run the following PS script to list the existing role assignments for your Service Principal account.
https://github.com/evandropaula/Azure/blob/master/ServicePrincipal/PS/List-ServicePrincipalRoleAssignments.ps1
You can run the following PS script to assign a role (e.g. Reader) to your Service Principal account.
https://github.com/evandropaula/Azure/blob/master/ServicePrincipal/PS/Assign-ServicePrincipalRole.ps1
It looks like I had contributor access, but my container registry was in a different resource group than my service principal. D'oh.
