SRE-Docker Compose for CRON job

Question

We had a task to Create a docker file with ubuntu image

1. Create a print.sh file which has code to print date and time
2. Write acron file named "hello-cron" which includes the print.sh to run for every 1 min.
3. The docker image should have a CRON job to print date and time every 1 min

We created a print.sh file via vi / vim command and in it given as

#!/bin/sh -l
time=$(date)
echo "::set-output name=time::$time"

After which we had executed -

chmod +x print.sh

then tried as -
