Pipelines fail on sleep

[amurashkin]

I am creating instance on digitalocan and then pulling waiting while it will be finalized. 

When it comes to "sleep" line, pipeline buld fails. I am using php:7.1.1 image

it works well for me locally.

My script for the pipeline looks like this:

#figure out droplet IP
locked=true
count=0
while [ $locked == true -a $count -lt 50 ]
do
rspns=$(curl -X GET -H "Content-Type: application/json" -H "Authorization: Bearer $DIGITAL_OCEAN_TOKEN" "https://api.digitalocean.com/v2/droplets/$DROPLET_ID" )
locked=$(echo $rspns | jq .droplet.locked)
echo "DROPLET $DROPLET_ID creation is IN PROGGRESS"
sleep 4

(( count++ ))
done

[ $locked == true ] && errcho "Unable to load droplet details"

Pipeline output:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

 git checkout -b <new-branch-name>
