I am getting crazy to achieve this very simple task.
I need to set an Output Variable in an Azure CLI task on Visual Studio Team Services, because next task in the Release definition will be executed according to the value of this variable.
I wrote this simple code
call az extension add --name azure-cli-iot-ext
call echo ##vso[task.setvariable variable=iotEdgeExists;]$(az iot hub query -n $(iotHub) -q "select * from devices.modules where devices.deviceId ='$(iotEdge)'")
which works, but not as exepected, in fact when I read the Ouput Variable in the next Azure CLI task and I try to print it on the screen I get the command string instead of the output...
call echo"$(az iot hub query -n <IOT_HUB> -q "select * from devices.modules where devices.deviceId ='<IOT_EDGE>'")"
What am I doing wrong?
If using Azure CLI version 2.* , you can use a powershell command rather than batch script wizardry. Microsoft's documentation found here
For example if you needed access token to update azure database it would look like so:
$token= & az account get-access-token --resource=https://database.windows.net --query accessToken
Write-Output("##vso[task.setvariable variable=sqlToken;]$token")
Don't forget to login first if testing locally:
az login
Install Azure cli here
Refer to this code below:
call {your command}>tmpFile1
set /p myvar= < tmpFile1
echo "##vso[task.setvariable variable=testvar;]%myvar%"
or
FOR /F "tokens=* USEBACKQ" %%F IN (`{your command}`) DO (
SET var=%%F
)
echo "##vso[task.setvariable variable=testvar;]%var%"
Mechaflash's answer in How to set commands output as a variable in a batch file
Inspired from the answer above but with some variation.
Works in an Azure CLI task on a Hosted Ubuntu agent in Microsoft DevOps as of July 2019.
This example runs an az command to fetch the full resource name of a storage account and sets it in the variable _StorageAccountNameVar for use in another pipeline task.
myvar=`az storage account list -g MyResourceGroup --query "[?contains(name, 'config')].name" -o tsv`
echo $myvar
echo "##vso[task.setvariable variable=_StorageAccountNameVar;]$myvar"
I've got some trouble (error code 255) with
FOR /F “tokens=* USEBACKQ” %%F IN (`az account get-access-token --resource=https://database.windows.net/ -query accessToken`) DO (
SET var=%%F
)
echo ##vso[task.setvariable variable=sqlToken;]%var%
So I used this (and that work for me)
for /f "tokens=1 USEBACKQ" %%F in (`az account get-access-token --resource=https://database.windows.net/ --query accessToken`) do echo ##vso[task.setvariable variable=sqltoken;]%%F

I am using powershell script in pipeline and the problem I have with this query.
$value = $(az appconfig kv show -n ThisisEnv --key thisisconfigkey) | ConvertFrom-Json
What this query does is get the data related to key if exist. If this key doesn't exist it give the error like
ERROR: Key 'abcdefg' with label 'None' does not exist.
It is work as expected. In pipeline when the key doesn't exist, it's printed a error on CLI. The pipeline see it as error and show it as failed. Is there a way I can make it work.
Is there a way I can stop it printing it on console. Any powershell operator which help me to get the value from azure command but also let me get it without print anything on console.
You could try to redirect the standard error using 2> $null
$value = $(az appconfig kv show -n ThisisEnv --key thisisconfigkey 2> $null) | ConvertFrom-Json
This will suppress the error within the console. You might also want to set the powerShellIgnoreLASTEXITCODE within the Azure CLI Task in order that the pipeline run doesn't fail - or as a workaround, set the $LASTEXITCODE to 0
I am trying to read in the access policies using the az cmdlets but struggling to do this. I thought this would work
$foo = az keyvault show -g "my-rg" -n "my-kv"
This returns a value back and was hoping to do:
$accessPolicies = $foo.accessPolicies
However this returns a null. I did notice the output produces properties so I also tried
$accessPolicies = $foo.properties.accessPolicies
Clearly doing something wrong here. Any ideas how I do this?
You could directly query the accessPolicies properties from the Azure CLI command.
$accessPolicies = az keyvault show -g "my-rg" -n "my-kv" --query 'properties.accessPolicies'
The --query parameter needs the JMESPath query string. See http://jmespath.org/ for more information and examples.
If you want to use the PowerShell commands, you can do it like this:
$accessPolicies= (Get-AzKeyVault -vaultname "my-kv" -resourcegroupname "my-rg").AccessPolicies
I ran the following AZ cli command below, whilst it provided me with the information I was after, I could not filter or select the columns I wanted.
az pipelines list --org org_url --project az_project --out table
I am after the name and status column only, and would like to filter on where the name matches the string "dev"
Another option i looked at was piping this out in Powershell
$output = az pipelines list --org org_url --project az_project --out table
$output | select-object name, status
I found that this didnt work either, as looking at the members of $output suggests it was not converted to a custom object. I am thinking there must be a way to do this in powershell.

This is what I was trying to do.
az pipelines list --org org_url --project az_project | ConvertFrom-Json -Depth 10 | Select Name,Status | where {$_.Name -like "*name*"}
I am trying to use variable in azure CLI like we used in powershell.
In powershell we define variable as follows
$LOCATION = value
And used it in command as follows
az group create --name foo --location $LOCATION
What I have tried :-
I have tried to find it out in Microsoft documentation
https://learn.microsoft.com/en-us/cli/azure/get-started-with-azure-cli?view=azure-cli-latest
but I did not get any information about that.
Question :-
How we can define variable in azure CLI?(like powershell)
How we can used it in command?(like powershell)
Note:- I have installed azure CLI at my local.
The easiest way to pass variables to any CLI command is by using environment variables
An environment variable is a variable whose value is set outside the
program, typically through a functionality built into the operating
system or microservice. An environment variable is made up of a
name/value pair, and any number may be created and available for
reference at a point in time.
Below you can find examples in Bash and CMD:
Bash-
Set new environment variable-
export LOCATION=westeurope
Print the environment variable-
echo ${LOCATION}
AZ CLI example-
az group create --name foo --location ${LOCATION}
CMD-
Set new environment variable-
set LOCATION=westeurope
Print the environment variable-
echo %LOCATION%
AZ CLI example-
az group create --name foo --location %LOCATION%
It is the same way you do it in powershell,
To assign a value
sajeetharan#Azure:~$ LOCATION="eastus"
To check value is set,
sajeetharan#Azure:~$ echo $LOCATION
eastus
You could do it like this:
New-Variable -Name "location" -Visibility Public -Value "eastus"
Azure Cloud Shell
Assignment: use double quotes if you are assigning a long string (export is not needed):
AZURE_STORAGE_CONNECTION_STRING="DefaultEndpointsProtocol=https;EndpointSuffix=core.windows.net;AccountName=MYACCNAME;AccountKey=MYACCKEY"
Usage: invoke/surround it with ${}, example:
checking Storage Queue messages:
az storage message peek \
--connection-string ${AZURE_STORAGE_CONNECTION_STRING} \
--queue-name MYQUEUE
printing:
echo ${AZURE_STORAGE_CONNECTION_STRING}
I'm trying to save a key value to pass on to the next step in my release pipeline, but no matter what I do I can't save the result of my command to a variable. I've already checked many of the articles here dealing with this with no success. Here is what I am trying:
$KEY=(az storage account show-connection-string --key primary -n myStorageAccount -g myResourceGroup --query "connectionString" -o tsv)
echo "Attempting to set variable"
echo $KEY
echo ##vso[task.setvariable variable=AZURE_STORAGE_CONNECTION_STRING;]$KEY
echo $AZURE_STORAGE_CONNECTION_STRING
Running on Windows Agent by the way. I've tried all kinds of variations: SET KEY=, SET $KEY=, SET $(KEY)=, $KEY=, $(KEY)=, KEY=, none of it works. Likewise I've tried referencing the variable differently in the echo statements with no luck. If I just run the az storage account command, I do get back the connection string. But either I get that $KEY is not a recognizeable command or if I'm using SET, echo simply gives me back $KEY and the vso line gives me nothing.
I can accomplish most of this, including saving to variable, in Azure Cloud Shell (via syntax $KEY= and echo $KEY). But of course that doesn't help my pipeline. Any idea the proper syntax to get this value into my next release pipeline step, or is the another method to accomplish this?
Can't set variable using Azure CLI within DevOps Release Pipeline
If you are using Azure CLI version 1.*, try to use following scripts:
for /f "tokens=1 USEBACKQ" %%F in (`Yourcommand`) do echo ##vso[task.setvariable variable=AZURE_STORAGE_CONNECTION_STRING;]%%F
If you are using Azure CLI version 2.*, you can also use a powershell command:
$KEY= & YourCommand
Write-Output("##vso[task.setvariable variable=AZURE_STORAGE_CONNECTION_STRING;]$KEY")
Check this thread for some more details.
Hope this helps.
