I am trying to fetch the ec2 instance id along with instance name(from ec2 tag 'Name' which mentioned the app name) and trying to return this combination separated with '_'. I am able to get this details quite fine from the AWS CLI on shell but when using the same aws cli command in Groovy Script, I am getting empty list
Groovy Script
import java.util.logging.LogManager
import java.util.logging.Level
import jenkins.model.Jenkins
def env = System.getenv()
logger.log(Level.INFO,"AWS Account is: "+aws_account)
logger.log(Level.INFO,"Region is: "+regions)
def output = []
try {
logger.log(Level.INFO,"Region is: "+"${regions}")
def command = "/usr/local/bin/aws ec2 describe-instances --profile ${aws_account} --region ${regions} --query [Reservations[*].Instances[*].{InstanceId:InstanceId,Tags:Tags[?Key == `Name`] | [0].Value}] --output text | tr '\t' '_'"
println("Command is: "+command)
def proc = command.execute()
proc.waitFor()
output = proc.in.text.tokenize()
}
catch(Exception e) {
logger.log(Level.SEVERE, e.getMessage(), e)
}
if(output.size() == 0)
throw new Exception("No instances found")
return output
Output received from AWS CLI Command directly from shell
