How to make blocking AWS CLI calls - amazon-web-services

Question

Most of the AWS CLI calls are asynchronous.
Therefore, after you call them, you have no idea if end product was successful or not.
Is there a simple solution for, checking if environment was created successfully, as an example, other than creating timed polling verification calls, etc etc.
Sorry I did not mention previously, but I am specifically looking for solutions from Powershell

Answer 1

You can check the Exit Status for cli command.
What is an exit code in bash shell?
Every Linux or Unix command executed by the shell script or user has
an exit status. Exit status is an integer number. 0 exit status means
the command was successful without any errors
code snippet:
aws cli command
if [ $? -ne 0 ]
then
echo "Error"
exit 1;
else
echo "Passed"
fi
another method is to wait for a response from the command :
while :
do
sleep 10
echo "Waiting for elasticsearch domain endpoint..."
local ELASTICSEARCH_ENDPOINT=$(aws es describe-elasticsearch-domain --domain-name ${ES_DOMAIN_NAME} --region ${AWS_REGION} --output text --query 'DomainStatus.Endpoints.vpc')
if [ ${ELASTICSEARCH_ENDPOINT} != "null" ]
then
echo "Elasticsearch endpoint: ${ELASTICSEARCH_ENDPOINT}"
break
fi
done
