I am trying to execute a script which needs to be run on Ubuntu 14.04 ec2 instance whenever the instance or it's image in auto scaling group spins up-
#!/bin/bash-x
REGION=`curl http://169.254.169.254/latest/dynamic/instance- identity/document|grep region|awk -F\" '{print $4}'`
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
cd
wget http://ftp.ruby-lang.org/pub/ruby/2.3/ruby-2.3.1.tar.gz
tar -xzvf ruby-2.3.1.tar.gz
cd ruby-2.3.1/
./configure
make
sudo make install
apt-get install apache2
cd /home/ubuntu
wget https://aws-codedeploy-$REGION.s3.amazonaws.com/latest/install
chmod +x ./install
./install auto
But the script never runs. I went to cloud-init-output.log file and following is the log details-
Cloud-init v. 0.7.5 running 'modules:final' at Mon, 12 Dec 2016 15:54:20 +0000. Up 36.92 seconds.

Specifically, I am trying to achieve is to install codedeploy in the instance.
To test this, I launched an Amazon Linux EC2 instance with #!/bin/bash-x
at the top of the User Data.
The log said:
/bin/sh: /var/lib/cloud/instance/scripts/part-001: /bin/bash-x: bad interpreter: No such file or directory
I re-launched it without the -x
and it worked fine.
So, that is definitely the cause of the problem for Amazon Linux. Things might be different with Ubuntu.
Update: As per sqlbot's suggestion (below), I tried it again with #!/bin/bash -x
(a space before -x
) and it worked fine.
