I am trying to push docker image into azure container registries repository using power-shell command as follows:-
docker push containerregone.azurecr.io/azure-vote-front:V1
it gives me following error
unauthorized: authentication required, visit https://aka.ms/acr/authorization for more information.
I have tried to find help related to this using following documentation
https://learn.microsoft.com/en-us/azure/container-registry/container-registry-faq
https://learn.microsoft.com/en-us/azure/container-registry/container-registry-authentication
but it gives Azure CLI commands.
I have also tried to do this using following link
https://stackoverflow.com/questions/50817945/what-is-the-powershell-equivalent-to-az-acr-login#:~:text=There%20is%20no%20single%20powershell,docker%20login%20to%20log%20in.
but they are using docker login. i don't have docker login.
My Question :-
How can we accomplish this using power-shell without docker login?
I'm afraid you cannot accomplish that using PowerShell without the command docker login. Let's take a look at the command for the ACR credential.
When you use the CLI command az acr login with the ACR directly without a docker daemon running, then you will get the error similar with this:
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is
the docker daemon running?
It means the CLI command az acr login depends on the docker server. When you run the CLI command az acr login --expose-token as the document shows, it just exposes the access token of the ACR without login for docker. You also need to log in yourself for docker. You can see the details here.
For the PowerShell for ACR, the only one is to get the ACR credential: Get-AzContainerRegistryCredential. But it gets the passwords for you only. It's not the access token, nor will log in for you too.
So, if you want to use PowerShell command to get the ACR credential, then you also need to log in yourself with the docker command.
Before push or pull, to azure, you need to login first by az-cli
az login
az acr login -n your-registry
or by docker
docker login your-registry.azurecr.io

I have a dedicated server with a private docker registry setup so I can push and pull images. I can connect to this server via docker login <my_domain>. I need to build an image using Azure Pipelines and push it to my registry, but when I try to make a docker connection, there is no way to access the private registry. Only docker hub, azure registry and "other" which still require docker id and password. Is there a way to connect Azure to my registry?
Ok, i figured out myself. It's not possible in this task, but u can change task from "Docker build" to "Bash script" and do docker login <your_domain>:<port> -u <your_username> -p <your_password> and then run anything you want, here specifically docker build.
I have a shell script that deploys containers to Azure Container Instances that runs fine locally using the Azure CLI (on Linux) but I'm having trouble performing the login to Azure from a pipeline task.
Locally the following command will open a browser to login:
docker login azure
The docs suggest that to do the same in a pipeline task I can pass in a client id and client secret. I think that it should look like this:
docker login azure --client-id $servicePrincipalId --client-secret $servicePrincipalKey --tenant-id $tenantId
However, when I run this in my pipeline I get this error:
unknown flag: --client-id
docker login azure --help run locally tells me that --client-id is a valid flag, so I'm wondering is there another way to do this in an Azure DevOps pipeline?
At the moment the problem is that there is no docker cli azure module installed on Microsoft Hosted agents, Installation instructions can be found here:
https://docs.docker.com/cloud/aci-integration/
The workaround I have used to solve the problem:
- script: |
# Add the compose-cli module;
curl -L https://raw.githubusercontent.com/docker/compose-cli/main/scripts/install/install_linux.sh | sh
# Login to Azure using docker CLI, you can use variables here;
# Note: Docker#2 task with Login Action will not help here;
docker login azure --client-id xxx --client-secret yyy --tenant-id zzz
# Check Context list;
docker context aci list
# Create ACI Context;
docker context create aci myaci --location <Azure Location> --resource-group <RG NAME> --subscription-id <subscription ID>
# Check It again.
docker context list
The Azure pipeline task for Docker allows you to use a service connection for the 'docker login' style task. To use a username / password combination, you'll start by creating a Service Connection of type 'Docker Registry'. Then specify 'other' for type. Here you can enter your credentials. The password is obfuscated for security as you would expect.
Now you can use this service connection in your azure devops pipeline docker tasks.

Application was using docker CLI to build and then push an image to azure container registry. Used to work fine on Kubernetes using a python module and docker.sock. But since cluster upgraded docker daemon is gone. Guessing the K8 backend no longer uses docker or has it installled. Also, since docker is going away in kubernetes (i think it said 1.24 I want to get away from counting on docker for the build.
So the application when working was python application running in a docker container. It would take the dockerfile and build it and push it to azure container registry. There are files that get pushed into the image via the dockerfile and they all exist in the same directory as the dockerfile.
Anyone know of different methods to achieve this?
I've been looking at Azure ACR Tasks but I'm not really sure how all the files get copied over to a task and have not been able to find any examples.
I can confirm that running an Azure ACR Task (Multi-Task or Quick Task) will copy the files over when the command is executed. We're using Azure ACR Quick Tasks to achieve something similar. If you're just trying to do the equivalent of docker build and docker push, Quick Tasks should work fine for you too.
For simplicity I'm gonna list the example for a Quick Task because that's what I've used mostly. Try the following steps from your local machine to see how it works. Same steps should also work from any other environment provided the machine is authenticated properly.
First make sure you are in the Dockerfile directory and then:
Authenticate to the Azure CLI using az login
Authenticate to your ACR using az acr login --name myacr.
Replace the values accordingly and run az acr build --registry myacr -g myacr_rg --image myacr.azurecr.io/myimage:v1.0 .
Your terminal should already show all of the steps that the Dockerfile is executing. Alternatively you can head over to your ACR and look under services>tasks>runs. You should see every line of the Docker build task appear there.
Note: If you're running this task in an automated fashion and also require access to internal/private resources during the image build, you should consider creating a Dedicated Agent Pool and deploying it in your VNET/SNET, instead of using the shared/public Agent Pools.
In my case, I'm using terraform to run the az acr build command and you can see the Dockerfile executes the COPY commands without any issues.
I'm new with Kubernetes and Azure. I want to Deply my application and I am floowing the microsoft tutorial about kubernetes. At first I have created the resouce group and ACR instance. When I try to login in ACR console show this error:
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
I'm using azure cli localy and I have docker running.
You can try below options to connect ACR :
run az acr login first with the --expose-token parameter. This option exposes an access token instead of logging in through the Docker CLI.
az acr login --name <acrName> --expose-token
Output displays the access token, abbreviated here:
{
"accessToken": "eyJhbGciOiJSUzI1NiIs[...]24V7wA",
"loginServer": "myregistry.azurecr.io"
}
For registry authentication, we recommend that you store the token credential in a safe location and follow recommended practices to manage docker login credentials. For example, store the token value in an environment variable:
TOKEN=$(az acr login --name <acrName> --expose-token --output tsv --query accessToken)
Then, run docker login, passing 00000000-0000-0000-0000-000000000000 as the username and using the access token as password:
docker login myregistry.azurecr.io --username 00000000-0000-0000-0000-000000000000 --password $TOKEN
you will get the below promt if you follow the above method :
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Login Succeeded
Seems your Docker Desktop is not running. Make sure you installed the Docker for Desktop on your machine and start it if not. You should be good once you start.
I used following quick start doc to spin up my first Azure container.
https://learn.microsoft.com/en-us/azure/container-instances/container-instances-quickstart#feedback
It worked fine. but how do I connect to container if I want to debug something?
You cannot connect to the container itself directly to debug, IE you can't SSH or RDP to it. Take a look at this graphic which highlights how a container differs from virtual machines:
You can however pull logs from your container from the container engine. In your case you would want to use the following command in the Azure CLI: az container logs.
https://aka.ms/container_logs
When you invoke CLI through the Portal, you should already be connected through your subscription.To debug or troubleshoot you can look at the container logs. Check out this documentation for the exact commands
https://learn.microsoft.com/en-us/cli/azure/container?view=azure-cli-latest#az-container-logs
When I am building containers to run on ACI, I build them first in a local docker instance where they can be connected to and interactively debugged. When you're happy with how they run locally push them into ACI, and debug from the output logs if needed.
I get to the bash shell in my Azure containers by either the azure-cli package, as the OP noted in a comment:
az container exec --exec-command "/bin/bash"
Or by navigating to a container instance in the Azure portal, then under Settings/Containers there is a "Connect" tab:
