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.

While learning how to use Azure Container Registry with the official tutorial : https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-portal?tabs=azure-cli
I tried to push images to my registry, the Hello World image in the course works fine, but when i try to use my own images it fails. It also fails when i pull images from docker and try to push them to my Azure registry.
Of course, the images are correctly tagged and the CLI connection works fine.
i'm also following another Azure course in which i build the image with Github actions ( https://learn.microsoft.com/en-us/azure/aks/kubernetes-action ), it also works great on the repo of this course, but once i try with my own projects, it fails. This time the error is about the url / the credentials :
After investigations, i'm sure that the credentials are correct, but the URL is maybe false because it never create it. That's why i was trying to push it manually in the first place.
EDIT : I managed to make it work by changing the wifi source i used, but i still don't understand how is this possible, why it doesn't work on github actions and what should i change in my conf to make it work with the original wifi again.
I tried to reproduce the same issue in my environment and got the below output
I have created the docker file and write the some script
vi dockerfile
FROM httpd:2.4
COPY ./public-html/ /usr/local/apache2/htdocs/
I have build the docker file using below command
docker build -t my-apache2 .
I have run the Image id using the below command
docker run -d -p 80:80 image_id
Created the container registry
After creating the registry we should enable the Access key if not we will not able to fetch the image to container instances
I have logged into the registry server
docker login login_server
Username:XXXX
password:XXXXX
After succeeded I have pushed the image into the container registry
I have tagged the image and pushed into the registry
docker tag image_name login_server/image_name
docker push login_server/image_name
Here we can find the image in repositories which we have pushed
I have created the container instance, while creating we have to give the Image resource as container registry then only we will get the pushed image
I've pushed an Image (which is a version of R + some libraries) on my private Azure Container Registry. How can build an Image starting from this Image?
In other words, I want to do "FROM registry/env:version" but I'm pretty sure that I need to use other settings to access my repository.
Thanks for help!
You should login your Docker daemon to your Azure Container Registry using the following command : docker login myregistry.azurecr.io --username $SP_APP_ID --password $SP_PASSWD
Then, using the fully qualified path for your image in the Dockerfile should work automatically, as long as the identity provided in the first step (login) has the rights to pull this image.
Sorry I'm trying to figure out your answer, I'm trying to pull a docker image from my Azure Container Registry and build it and push it back to a new repository. I'm starting my Dockerfile as
FROM xxxxxx.azurecr.io/php-7.4:latest AS compiled
how to configure the docker daemon in azure pipelines world?
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 have created an Azure Registry where I deploy some docker container from the CD\CI in Azure DevOps.
Following the Microsoft documentation, I have created a service principal. So, I have username and password to use to pull images from the Azure Container Registry. I tried to pull the images locally and it is working. To connect to the Container registry I use this command:
docker login myazureregistry.azurecr.io --username --password
Now, I want to create a virtual machine in Azure to publicly access to the application in the container.
I created an Ubuntu virtual machine and installed Docker. I run the same command as before on the Ubuntu machine but I got an error:
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.39/auth: dial unix /var/run/docker.sock: connect: permission denied
What is the problem? How have I to configure Ubuntu to connect to the Azure Container?
Maybe you don't have permissions for use docker.
Add your user to docker group for use docker command without sudo
sudo groupadd docker
sudo usermod -aG docker $USER
And after this run your login command. (If you use virtual machine, it may be necessary to restart the virtual machine for changes to take effect)
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
