Issue

I have provided an .sh file as user_data in my Terraform script:

resource "aws_instance" "alpha-terraform"{
    ami=var.amis[var.region]
    instance_type="t2.micro"
    vpc_security_group_ids=[aws_security_group.alpha-terraform-sg.id]
    user_data = file("user_data_bootstrap.sh")
    key_name = "alpha-terraform"

    tags={
        type="alpha"
        purpose="terraform"        
    }
}

The .sh file contains:

#Jenkins Installation:
sudo apt update
sudo apt install openjdk-8-jdk --yes
wget –q –O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add –
sudo sh -c 'echo deb https://pkg.jenkins.io/debian binary/ >> /etc/apt/sources.list'
sudo apt update
sudo apt install Jenkins
sudo systemctl status jenkins
find /usr/lib/jvm/java-1.8* | head -n 3

My instance is getting created all right. However, I believe my user_data is not getting executed. I can see the user_data is being copied to /var/lib/cloud/instance/ as user-data.txt and user-data.txt.i but still not getting executed.

Why is this happening and how can I debug it further?

Update

I tried accessing the server through and executing each command one by one but getting following error while updating apt packages:

ubuntu@ip-172-31-52-**:~$ apt update

Solution

I verified the script on my sandbox account.

It had mistakes. The corrected version is as follows:

#!/bin/bash -xe

#Jenkins Installation:
apt update
apt install openjdk-8-jdk --yes
wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -
echo "deb https://pkg.jenkins.io/debian binary/" >> /etc/apt/sources.list
apt update
apt install -y jenkins
systemctl status jenkins
find /usr/lib/jvm/java-1.8* | head -n 3

The changes were:

removal of sudo
fixing – to -
fixing apt install Jenkins to apt install -y jenkins

I can confirm that it works now with terraform on Ubuntu 18.04 instance.

Upon launching the instance, jenkins is available at http://<instance-ip>:8080:
