How can I consume variables set in CI pipeline directly in CD pipeline?
Example:
If there are multiply variables declared in one group. How to access particular variable in CI/CD pipeline?
Also how to use variable groups for multiple keyvault's?
Thank you

Based on Richard's answer, I managed to set the value of a variable in a variable group to a variable coming from a CI pipeline, and then to read that variable in a CD pipeline.
For that, it is necessary:
To have previously created the variable group, and the variable (its name identified by $(variableName). Let's assume its value would be stored in $(variableValue)).
To find the variable group ID (stored in $(variableGroupId)), which can be done by navigating on Azure DevOps to that variable group. The group ID will then be in the URL.
A Personal Access Token (PAT) with Read & Write access to group variables (called $(personalAccessToken) )
CI pipeline
- powershell: |
az pipelines variable-group variable update --group-id $(variableGroupId) --name $(variableName) --value $(variableValue)
displayName: 'Store the variable in a group variable'
env:
AZURE_DEVOPS_EXT_PAT: $(personalAccessToken)
Then all that's necessary, is to declare the variable group in the CD pipeline. If this variable group is called MyVariableGroup, it can be done in the following way:
CD pipeline
variables:
- group: MyVariableGroup
The variable that was previously set in the CI pipeline, will then be available in the CD pipeline.

I am trying to create a dynamic variable on Azure Devops pipeline and I cannot use it on further tasks although the task with the variable creation is successfully completed.
Write-Host "##vso[task.setvariable variable=mytitle;isOutput=true]$content
How can I use the variable that is created dynamically with setvariable
Please note that the first task can set a variable, and following tasks are able to use the variable using macro syntax $(myVar). We are not able to use it in the first task. The variable will only be available to tasks in the same job by default, and the variable is exposed to the following tasks as an environment variable.
For example:
jobs:
- job: A
steps:
- powershell: |
Write-Host "##vso[task.setvariable variable=mytitle]$content"
name: setVariable
- powershell: |
Write-Host "You can use macro syntax for variables: $(mytitle)"
name: PrintVariable
If you add the parameter isoutput, the syntax to call your variable changes. See Set an output variable for use in the same job and Set an output variable for use in future jobs for details.
More information please refer to Logging commands.
I have a requirement to pass data between 2 release pipelines (to trigger 2nd pipeline on completion of 1st pipeline).
Can we pass variables dynamically between azure RELEASE pipelines using trigger an Azure DevOps pipeline extension?
I tried this blog but unable to find/understand if we can use "output variables" to pass data between azure release pipelines.
https://msftplayground.com/2019/02/trigger-a-pipeline-from-an-azure-devops-pipeline/
Thank you in advance!
Output variables are created by the pipeline and referenced by the other tasks in the pipeline, it means they are dynamic and refers to the result of a particular task.
These cannot be defined statically.
After running the task in the pipeline, output variables value can be known.
There are two different ways to create output variables :
By building support for the variable in the task itself
Setting the value ad-hoc in a script
Below example is defining a task with the name SomeTask that natively creates an output variable called out.
In a task within that same job, you can reference that variable using $(SomeTask.out).
steps:
- task: MyTask#1
name: SomeTask
- script: echo $(SomeTask.out)
For the detailed information regarding how to create output variables and pass between the pipelines, please refer azure devops output variables.
Is there a way to pass the Azure DevOps pipeline secrets without passing them as task env variables
As per the documentation, we can only pass the secrets like below
- powershell: |
Write-Host "recommended: $env:MY_MAPPED_ENV_VAR"
env:
MY_MAPPED_ENV_VAR: $(mySecret) # the recommended way to map to an env variable
This works okay when you have 1 or 2 variables, but managing 20 or more than that becomes so tedious.
Any comments or suggestions would be greatly appreciated
Update:
Is there a way to pass the Azure DevOps pipeline secrets without passing them as task env variables
I'm afraid there is no method to use secret variables directly without mapping them to the task environment.
From the document you mentioned：
Don't set secret variables in your YAML file. Operating systems often
log commands for the processes that they run, and you wouldn't want
the log to include a secret that you passed in as an input. Use the
script's environment or map the variable within the variables block to
pass secrets to your pipeline.
We don't recommend passing the secret variables directly into pipeline. So we could use the env variable to map the secret variable.
Generally, we only place a small number of secret variables in a single task.
Therefore, it is valuable to use environment variables to map secret variables.
I have two pipelines(Pipeline A and Pipeline B) configured for build and release and Pipeline A triggers Pipeline B for deployment.
I defined variables on pipeline A and need them on pipeline B to use for deployment . is it possible to pass them between two these pipelines ?.
any leads are much appreciated.
You can use for that variable group. Here you have doc about variable group.
Use a variable group to store values that you want to control and make available across multiple pipelines. You can also use variable groups to store secrets and other values that might need to be passed into a YAML pipeline. Variable groups are defined and managed in the Library page under Pipelines.
What you need is declare the same variable in both pipelines:
variables:
- group: my-variable-group
and for instance if you want to update variable in one pipeline and have this updated value available in second you can use Azure CLI
az pipelines variable-group variable update --group-id
--name
[--detect {false, true}]
[--new-name]
[--org]
[--project]
[--prompt-value {false, true}]
[--secret {false, true}]
[--value]
You should call this command from Azure CLI task
- task: AzureCLI#2
displayName: Azure CLI
inputs:
azureSubscription: <Name of the Azure Resource Manager service connection>
scriptType: ps
scriptLocation: inlineScript
inlineScript: |
az --version
az pipelines variable-group --group-id value-of-group-id --name some-name --org your-org --project your-project --value some-value
And if you wanto to Trigger one pipeline after another you can use pipeline resource:
resources:
pipelines:
- pipeline: securitylib # Name of the pipeline resource
source: security-lib-ci # Name of the pipeline referenced by the pipeline resource
trigger:
branches:
- releases/*
- master
Just like Krzysztof Madej pointed out, Variable groups will help to share static values across builds and releases pipeline.
What you need is a way to pass variables from one pipeline to another. I'm afraid to say there is no official way to do this for now.
As a workaround you could update the value of your variables inside your variable group. There are multiple ways to handle this, Rest API, powershell, 3rd-party extension. Detail ways please refer answers in this question: How to Increase/Update Variable Group value using Azure Devops Build Definition?
If you want to get the value of variable in the pipeline. Since you have used logging command to update that variable.
What you need to do only is using Rest API to get that particular build log to fetch related info.
How to pass variables from one pipeline to another pipeline in azure devops
You could set some default variables in the release pipeline, then add a inline powershell task to invoke the REST API (Definitions - Update) to update the value of the release definition variable in the build pipeline with values comes from build pipeline.
PUT https://vsrm.dev.azure.com/{organization}/{project}/_apis/release/definitions?api-version=5.0
Now, we could use the values from multiple pipelines in the release pipeline.
Please check my previous thread for some more details.
Note：Do not forget to use REST API to restore those changed variables to the default value, so that we could use it next time.
i have a branch in git with a .yaml build file which has a script to simply print out the value of the variable declared in the .yaml
if i run the command: az pipelines run --id 999 --variables "myvar=myvar" I expected the variable to change as I am injecting it. it doesnt.
am i misunderstanding what this switch does? if so, what is it supposed to do and/or how can i achieve my goal?

For az pipelines variable ,there are four commands
az pipelines variable create Add a variable to a pipeline.
az pipelines variable delete Delete a variable from pipeline.
az pipelines variable list List the variables in a pipeline.
az pipelines variable updateUpdate a variable in a pipeline.
You should use az pipelines variable update command to update a variable in a pipeline.
Command sample:
az pipelines variable update --name
