As outlined below, the installation will be completed in five simple steps. Node JS installation process is very streamlined. By installing Node JS, we will also install Node Package Manager (NPM) that can be later used to download Node JS modules.
More precisely, we will focus Node JS 8 installation on CentOS 7. As a starter, in this post we will revisit with the basic, Node JS installation. More posts about Node JS and sample applications are forthcoming. Having a wide OS support further accelerates Node JS adoption within the server-side technology stack. The executable can run on major OSes that include Windows, GNU Linux, and Mac OS. The asynchronous event-driven feature built into Node JS can be considered a killer feature that may flatter a system architect planning to build a high-performing server-side component serving HTTP webservice to the clients.
Key_name = "my-key-pair" key_path = "~/.ssh/my-key-pair.Node JS has been gaining more popularity as the server-side runtime environment of choice these recent years. # Configure the SSH key for remote access Group vpc_security_group_ids = Įcho "const express = require('express')" > index.jsĮcho "app.get('/', (req, res) => )" > index.js Here is an example Terraform deployment script for deploying a Node.js microservice in AWS: #terraformĪmi = var.ami instance_type = var.instance_type Use the file provisioner to upload files to the EC2 instance.Use the remote-exec provisioner to run commands on the EC2 instance.Use the aws_security_group resource to configure a security group for the EC2 instance.Use the aws_ebs_volume resource to create an EBS volume for data storage.Use the aws_instance resource to create an EC2 instance.Define the necessary input variables and output values.Use Terraform modules to abstract complex configurations.Define the AWS infrastructure resources using the Terraform syntax.Configure the Node.js application to listen on a specific port.Write the Node.js code for the microservice.Configure a security group to allow traffic to the EC2 instance.Create an Amazon Elastic Block Store (EBS) volume for data storage.Create an Amazon Elastic Compute Cloud (EC2) instance.
Deploying a Node.js microservice in AWS using Terraform involves several steps, including setting up the AWS infrastructure, configuring a Node.js application, and creating a Terraform deployment script.
