I am working with Terraform to luanch an Ec2 instance, where I want to execute some commands. I put a bash file in user_data on aws_instance resource, but the file is not executed.
...
resource "aws_instance" "master" {
ami = lookup(var.amis, var.region)
instance_type = var.master_instance_type
key_name = "id_rsa_sdtd"
security_groups = [aws_security_group.SDTD_VPC_Security_Group.id]
subnet_id = aws_subnet.SDTD_VPC_Subnet.id
iam_instance_profile = "k8s-cluster-iam-master-role"
user_data = file("./master_config.sh")
}
...
Terraform plan
...
+ tenancy = (known after apply)
+ user_data = "def16ed029e3ecb79f09f750c548beed53d7f60d"
+ volume_tags = (known after apply)
...
my bash file
#!/bin/bash
# Install kubeadm and Docker
sudo apt update && sudo apt -y upgrade
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
sudo bash -c 'echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" > /etc/apt/sources.list.d/kubernetes.list'
sudo apt update
sudo apt install -y docker-ce kubelet kubeadm kubectl
...There is no word in your question confirming master_config.sh hasnt been executed.
Below line doesnt mean it hasnt been executed. If it doesnt work - you should definitely see a log /var/log/cloud-init-output.log as suggested in the comments
+ user_data = "def16ed029e3ecb79f09f750c548beed53d7f60d"
From the solutions that comes to my mind:
file("./master_config.sh"). Maybe you wrapped in incorrectly.resource "aws_instance" "..." {
user_data = "${file("/../../master_config.sh")}"
...
}
data "template_file" "user_data" {
template = "${file("/../../master_config.sh")}"
...
}
resource "aws_instance" "master" {
user_data = "${data.template_file.user_data.rendered}"
...
}
