list index out of range

[Alex Maccabi]

Hey,

Had anyone had or saw this kind of error:

list index out of range

Failed: NonZeroResultCode: Result code was 255

My workflow is like this:

deploy app to remote node on AWS, the node list is generated with aws plugin tags and etc.

create ami with aws api (aws ec2 create-image).

then run a script locally "/bin/bash -c /var/lib/rundeck/tagami.sh"

the script:

#! /bin/bash

AMI_ID=`aws ec2 describe-images --profile $RD_OPTION_NODE_ENV --filters "Name=name,Values=$RD_OPTION_TAG-build-$RD_OPTION_BUILDNUMBER" --query 'Images[*].{ID:ImageId}'`

VERSION=`echo $RD_OPTION_TAG | cut -d '_' -f 3`

aws ec2 create-tags --profile $RD_OPTION_NODE_ENV --resources $AMI_ID  --tags Key=Role,Value=$RD_OPTION_APP_NAME Key=Version,Value=$VERSION

exit 0

basically it tags the instance, so I could continue with the flow (Netflix Asgard).

its mixed success, sometimes it fails with the 'list index out of range' I've added 'exit 0' I though maybe it isn't exiting correctly and sometimes it works.

I've created another job that contains only the script for the tagging and it seems to work.

please advice.

It looks like a bash error to me. It's failing before it gets to the 'exit 0'. 

You might set the shell option, set -eu, to fail faster.

Yes, I see this error when I run the "create-tags" command and the parameter for --resources is empty because of an error in my bash script's parameter handling.

In this case, check that "$AMI_ID" always resolves to something nonempty.
