Using Jenkins and Terraform EC2 auto deploy issues - amazon-web-services

Question

I am new to DevOps. I am trying to deploy EC2 instances using the following script. It is failing on Terraform initializing stage. I do have the terraform init in my code. where is the issue?
pipeline {
parameters {
string(name: 'environment', defaultValue: 'terraform', description: 'Workspace/environment file to use for deployment')
booleanParam(name: 'autoApprove', defaultValue: false, description: 'Automatically run apply after generating plan?')
}
environment {
AWS_ACCESS_KEY_ID = credentials('AWS_ACCESS_KEY_ID')
AWS_SECRET_ACCESS_KEY = credentials('AWS_SECRET_ACCESS_KEY')
}
agent any
options {
timestamps ()
}
stages {
stage('checkout') {
steps {
script{
dir("terraform")
{
git "https://github.com/Ravinderhub/Jenkins-Terraform-AWS.git"
}
}
}
}
stage('Plan') {
steps {
sh 'pwd;cd terraform/aws-instance-first-script ; terraform init -input=false'
sh 'pwd;cd terraform/aws-instance-first-script ; terraform workspace new ${environment}'
sh 'pwd;cd terraform/aws-instance-first-script ; terraform workspace select ${environment}'
sh "pwd;cd terraform/aws-instance-first-script ;terraform plan -input=false -out tfplan "
sh 'pwd;cd terraform/aws-instance-first-script ;terraform show -no-color tfplan > tfplan.txt'
}
}
stage('Approval') {
when {
not {
equals expected: true, actual: params.autoApprove
}
}
steps {
script {
def plan = readFile 'terraform/aws-instance-first-script/tfplan.txt'
input message: "Do you want to apply the plan?",
parameters: [text(name: 'Plan', description: 'Please review the plan', defaultValue: plan)]
}
}
}
stage('Apply') {
steps {
sh "pwd;cd terraform/aws-instance-first-script ; terraform apply -input=false tfplan"
}
}
}
}

Answer 1

There is an invalid variable in the configuration which prevents initialization.
ami_id variable defines an invalid type.
Correct that to:
variable "ami_id" {
type = "map"
default = {
us-east-1 = "ami-035b3c7efe6d061d5"
eu-west-2 = "ami-132b3c7efe6sdfdsfd"
eu-central-1 = "ami-9787h5h6nsn"
}
}
