无法在 DevOps Release Pipeline 中使用 Azure CLI 设置变量

Question

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.
