This part works just fine.



The script then attempts to execute the bash script using "commands:"
This doesn't work. - Any ideas please?



deployComposer:
files:
/var/composer/composer.sh:
content: !Join
- ''

#!/bin/sh

EXPECTED_SIGNATURE="$(wget -q -O -
https://composer.github.io/installer.sig)"
sudo php -r "copy('https://getcomposer.org/installer',
'composer-setup.php');"
ACTUAL_SIGNATURE="$(php -r "echo hash_file('sha384', 'composer-setup.php');")"

if [ "$EXPECTED_SIGNATURE" != "$ACTUAL_SIGNATURE" ]
then
>&2 echo 'ERROR: Invalid installer signature'
sudo rm composer-setup.php
exit 1
fi

sudo php composer-setup.php --quiet
RESULT=$?
sudo rm -rf composer-setup.php

sudo mv composer.phar /usr/local/bin/composer

exit $RESULT
mode: '000777'
