I'm trying to push a built docker image in a release pipeline.
My docker build task yaml is:
steps:
- task: Docker#2
displayName: Build
inputs:
containerRegistry: MyRegistry
repository: myrepo/containername
command: build
Dockerfile: '$(System.DefaultWorkingDirectory)/My.dockerfile'
buildContext: '$(System.DefaultWorkingDirectory)'
arguments: '--build-arg FILE_NAME=myfile.zip'
My docker push task yaml is:
steps:
- task: Docker#2
displayName: Push
inputs:
containerRegistry: MyRegistry
repository: myrepo/containername
command: push
The log says it runs this command:
/usr/bin/docker push ***/myrepo/containername:tag
The tasks reports success, but I can't see the resulting image in dockerhub.
I wonder if the *** has anything to do with this?
I ended up not using the Azure DevOps tasks and writing the commands via a python script. It was important to docker login inside the python script also.

I would like to run a docker container, which i pull from Azure Container Registry. All of this i would like to do in Azure DevOps pipeline.
Firstly i created sample Node.js app and Dockerized it with this tutorial: https://nodejs.org/en/docs/guides/nodejs-docker-webapp/
Then i did my Azure Pipeline which firstly do build&push and then pull and run.
My pipeline:
stages:
- stage: Build
displayName: Build and push stage
jobs:
- job: Build
displayName: Build
pool:
vmImage: $(vmImageName)
steps:
- task: Docker#2
displayName: Build and push an image to container registry
inputs:
command: buildAndPush
repository: $(imageRepository)
dockerfile: $(dockerfilePath)
containerRegistry: $(dockerRegistryServiceConnection)
tags: |
$(tag)
- task: Docker#2
displayName: Docker pull
inputs:
command: pull
containerRegistry: $(dockerRegistryServiceConnection)
arguments: container01.azurecr.io/devopsnodejs:latest
- task: Docker#2
displayName: Login to ACR
inputs:
command: login
containerRegistry: $(dockerRegistryServiceConnection)
- script: |
docker run -p 49160:8080 -d container01.azurecr.io/devopsnodejs:latest
The pipelines runs every step sucessfully, the last script with docker run prints this to Azure DevOps console
Generating script.
Script contents:
docker run -p 49160:8080 -d ***/devopsnodejs:latest
========================== Starting Command Output ===========================
/usr/bin/bash --noprofile --norc /home/vsts/work/_temp/b117892d-e34c-484c-ad8c-f99cd0a97e18.sh
7c6c9d548c4be3e4568e56ffc87cca27e698fc53b5ec15a1595cd45fe72dd143
And now the problem is that, I cannot acces the app which should return simply get request saying 'Hello World'
Im trying to go to localhost:49160, to curl -i localhost:49160 but there is only curl: (7) Failed to connect to localhost port 49160 after 2258 ms: Connection refused
Also, if i do it locally, not in azure pipelines, so I simply run docker pull container01.azurecr.io/devopsnodejs:latest and docker run -p 49160:8080 -d container01.azurecr.io/devopsnodejs:latest in powershell, the docker ps will show me this container, as well as the curl -i localhost:49160 will work. Am I able to access this locally, or if i run it in Azure Pipelines it will work only there?
Have you seen this question already, which is I think your scenario?
Cannot conect to Docker container running in VSTS
You could use a bash script with ssh to logon to the target machine and perform docker commands on the machine. The following is just an example. I have something like this in one of my pipelines.
- task: Bash#3
displayName: "Deploy image $(imageName)"
inputs:
targetType: 'inline'
failOnStderr: false
script: |
sshpass -p '$(localroot-userpassword)' ssh -o StrictHostKeyChecking=no $(localroot-username)#$(remoteHost) "{ sudo docker stop $(imageName) ; sudo docker rm $(imageName) ; sudo docker pull $(imageName) ; sudo docker run ...#add other commands separated by semicolon}"
We build our docker image with a custom .sh file. Then we would like to push it to our azure registry. We have the following step in our azure pipeline:
- task: Docker#2
inputs:
containerRegistry: 'someazureregistry'
repository: 'appname'
command: 'push'
tags: 'latest'
The build is successfull, and as can be seen below it is registered in docker as appname:latest , however for some reason azure does not find it, and asks for an image with the tag ***/appname.
/usr/bin/docker images
/usr/bin/docker push ***/appname:latest
REPOSITORY TAG IMAGE ID CREATED SIZE
appname latest f1e11b4fc19c Less than a second ago 680MB
ubuntu 20.04 a0ce5a295b63 7 days ago 72.8MB
...
The push refers to repository [***/appname]
An image does not exist locally with the tag: ***/appname
##[error]An image does not exist locally with the tag: ***/appname
We have tried different combinations of tags. What is azure expecting here?
It looks like you are building the Docker image separately. Please note that the container image needs to be tag locally for the private container registry before it can be pushed. As Shayki Abramczyk mentioned you need to build the image with containerRegistry.
To resolve this issue you must Tag the image using the "docker tag" command with the specific private container registry.
For example:
docker tag image youoregistryhost:port/xxx/image-name:latest
Besides, you can build and push the Docker image together in Azure DevOps pipeline. The following YAML file for your reference:
variables:
# Container registry service connection established during pipeline creation
dockerRegistryServiceConnection: 'testacr'
imageRepository: 'appname'
containerRegistry: 'xxx.azurecr.io'
dockerfilePath: '$(Build.SourcesDirectory)/app/Dockerfile'
tag: 'latest'
system.debug : true
# Agent VM image name
vmImageName: 'ubuntu-latest'
stages:
- stage: Build
displayName: Build and push stage
jobs:
- job: Build
displayName: Build
pool:
vmImage: $(vmImageName)
steps:
- task: Docker#2
displayName: Build and push an image to container registry
inputs:
command: buildAndPush
repository: $(imageRepository)
dockerfile: $(dockerfilePath)
containerRegistry: $(dockerRegistryServiceConnection)
tags: |
$(tag)
Of course you can also build and push the image separately in Azure DevOps pipeline like this:
stages:
- stage: Build
displayName: Build and push stage
jobs:
- job: Build
displayName: Build
pool:
vmImage: $(vmImageName)
steps:
- task: Docker#2
displayName: Build an image for container registry
inputs:
containerRegistry: '$(dockerRegistryServiceConnection)'
repository: '$(imageRepository)'
command: 'build'
Dockerfile: '$(dockerfilePath)'
tags: 'latest'
- task: Docker#2
displayName: Push an image to container registry
inputs:
containerRegistry: '$(dockerRegistryServiceConnection)'
repository: '$(imageRepository)'
command: 'push'
tags: 'latest'
I have pushed a new image in the azure container registry
But i am unable to find the image in azure container registry
Please find the deplyment yaml file
name: Dotnet Code Build and Push
jobs:
- job: Job_1
displayName: Agent job 1
pool:
vmImage: ubuntu-18.04
steps:
- checkout: self
- task: Docker#0
displayName: Build an image
inputs:
azureSubscription: 'sc-***dp'
azureContainerRegistry:
loginServer: *****aksacr.azurecr.io
id: "/subscriptions/4f76bb2f-c521-45d1-b311-b87bf**747ff/resourceGroups/eus-***dp-rg/providers/Microsoft.ContainerRegistry/registries/*****aksacr"
imageName: ***dpacr.azurecr.io/ims-***dp/$(Build.Repository.Name):$(Build.BuildId)
- task: Docker#2
displayName: Login to ACR
inputs:
command: login
containerRegistry:'sc-***dp'
- task: Docker#2
displayName: Push an image
inputs:
azureSubscription: 'sc-***dp'
repository: ims-***dp
azureContainerRegistry: '{"loginServer":"*****aksacr.azurecr.io", "id" : "/subscriptions/4f76bb2f-c521-45d1-b311-b87bf**747ff/resourceGroups/eus-***dp-rg/providers/Microsoft.ContainerRegistry/registries/*****aksacr"}'
action: Push an image
I would recommend to create a new service connection with the container registry if one does not exist.
and select Azure Container Registry.
Then you can push in your registry using the below task. Keep in mind that ${{container}} should have a notation as xxx.azurecr.io/imagename:tag
- task: Docker#2
displayName: pushing image ${{container}}
inputs:
containerRegistry: 'serviceConnectionName'
repository: '${{container}}'
command: 'push'
tags: |
mytag
Try to push the code in azure devops pipeline so you can directly push image in azure container registry
Here we can docker task it can build up and push the image with help of setting and it take the image from repository and then it can push into the azure container registry
task: Docker#2
displayName: Push an image
inputs:
command: buildAndpush
repository: $(imageRepository)
dockerfile: $(dockerfilepath)
ContainerRegistry: $(dockerRepositoryserviceconnectio)
tags:
$(tag)
Save and run.
Note : After running you can't see Repository please refresh again because in azure pipeline the job may be still running once the job is completed & successfully run and refresh you can able see image is pushed
Please refer this document by rajaniesh kaushikk has given detail information
Please check the repository and containerRegistry value in your Docker#2 task, make sure they points to target resource. My script for your reference below. Please note the parameters in Docker#2 task, no azureContainerRegistry and command needed.
variables:
dockerRegistryServiceConnection: acrconn1
imageRepository: 'acrlearn'
containerRegistry: 'test.azurecr.io'
dockerfilePath: '$(Build.SourcesDirectory)/Dockerfile'
tag: '$(Build.BuildId)'
# Agent VM image name
vmImageName: 'windows-latest'

I'm currently playing around with docker containers and azure devops with the goal to run a couple of tests from it.
This is what I currently do:
I have created a dockerfile in my repo
I have created a pipline that build and push an image to container registry
I have checked that the image exist in container registry
I have started on a new release pipline with the following task:
A login task:
steps:
- task: Docker#2
displayName: Login
inputs:
containerRegistry: nameOfMyRegistry
command: login
A run task:
steps:
- task: Docker#2
displayName: 'Run tests'
inputs:
containerRegistry: nameOfRegistry
repository: nameOfRepository
command: run
arguments: 'nameOfImage -p 8089:8089 -f tests.py --run-time 30s -u 1 -r 1'
But after I run this I get the following error:
2021-04-26T11:39:38.9204965Z ##[error]Unable to find image 'nameOfMyImage:latest' locally
2021-04-26T11:39:38.9228444Z ##[error]docker: Error response from daemon: manifest for nameOfMyImage:latest not found: manifest unknown: manifest tagged by "latest" is not found.
So I'm not sure if I'm missing something? I put in all information to my azure container registry so I thought it would just get the image from it but it seems like it can't find it.
I know I got answer that say you can't use run with the Docker#2 task but I actually managed to get it to run now. The problem was that I used the wrong name of the image. I had to write it like this:
nameOfRegistry.azurecr.io/nameOfRepository:tag
So just bad from me but I will leave this here if someone manage to do the same mistake.
Nothing complex, looks like task input command supports only buildAndPush, build, push, login, logout and it doesn't support run reference
Something like this with script should work. reference
resources:
containers:
- container: builder
image: ubuntu:18.04
steps:
- script: echo "I can run inside the container (it starts by default)"
target:
container: builder
There is no option run in specification
https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/build/docker?view=azure-devops#task-inputs
To build an application and run tests right after the build you can use following commands:
steps:
- task: Docker#2
displayName: Login to ACR
inputs:
command: login
containerRegistry: dockerRegistryServiceConnection1
- task: Docker#2
displayName: Build
inputs:
command: build
repository: contosoRepository
tags: tag1
If you want to run tests in Docker container, you should use
Container Structure Tests

I am building a Docker image in my Azure pipeline. Now, I want to push this image to multiple aws accounts(dev, stage, prod) depending on the configuration parameters. The problem is, image is not available in publish artifact. I came across this and this article during my research. I am confused about the solution regarding saving the docker image so it can be available in publish artifact. I have two specific questions:
How will I use the docker save command in Azure pipeline task after docker build. The available docker task doesn't have this command.
Is there any better way of doing this apart from saving an image.
How will I use the docker save command in Azure pipeline task after docker build. The available docker task doesn't have this command.
This related to the task version.
Steps: Add task docker->switch the task version to 0->select the option Run a Docker command, then we could run the docker save command, check the pic below.
Is there any better way of doing this apart from saving an image.
We recommend that you use this to upload the docker image as an artifact.
Nowadays the preferred way of writing pipelines is with yaml.
Please see my code on how to do it in a multistage pipeline with Artifactory docker registry.
If we are in master the the MY_ADDITIONAL_TAG will be also pushed.

After a lot of reserach I found this article which resolved my issue https://dev.to/n3wt0n/container-image-promotion-across-environments-build-artifact-5887
Note: We can manually add commands which are not present in the Docker task snippet available in Azure DevOps. This is also mentioned in the article and steps to do this.
