Azure cli and a while loop to check for status

Question

have got an azure asynch operation which returns one of 3 statuses, the code is written in bash. Please see https://video2.skills-academy.com/en-us/rest/api/sql/failovergroups/failover

Succeeded  
Failed  
Canceled

The issue with the code snippet below is that, it is not waiting for any of the 3 statuses above to be returned before it exits, sometimes the process runs very fast and sometimes its very slow. Ideally I feel that a loop is required where it will wait for any of the 3 statues above to be returned and then exit.

steps:  
  - task: AzureCLI@1  
    displayName: Failover  
    inputs:  
      azureSubscription: Sub  
      scriptLocation: inlineScript  
      inlineScript: |  
  
        URL=$(grep Azure-AsyncOperation out.log | sed "s/'//g" | sed "s/Azure-AsyncOperation: //g")  
        STATUS=$(az rest --method GET --url ${URL} --query 'status' -o tsv)  
         
        if [ ! ${STATUS} == "Succeeded" ]  
        then  
          echo "Operation did not succeed"  
          echo "Operation status is ${STATUS}"  
          exit 1                   
        fi  
  
        echo "Operation succeeded"

While the status variable is not null or populated

If the status is == Failed then exit 1 and echo message saying failed
If the status is == cancelled then exit 1 and echo message saying failed
If the status is == Succeeded then exit 0 and echo message saying the processed successfully completed.

How can I achieve this in bash ?

From the looks of it you are trying to do as documented here. If that is the case you are right in saying the Loop is required to find out the details and the operation with URL to complete. Here is the sample code we wrote for the same:

STATUS=$(az rest --method GET --url ${URL} --query 'status' -o tsv)  
while [ -z $STATUS ] #-z is empty string, may need to modify if there is also a Status = pending option  
    do  
        echo "waiting for result"  
        sleep 1 #delay in seconds  
        #if pending statuses happen, poll the API endpoint again to get the latest status  
    done  
if [ ! ${STATUS} == "Succeeded" ]  
  then  
    echo "Operation did not succeed"  
    echo "Operation status is ${STATUS}"  
    exit 1  
  else  
    #handle Suceeded status  
  fi

If this still doesn't work please get back to us with the URL and .log file data to TS it further.
