Objective

Learn how to set up an EC2 machine on AWS.

Steps

Create an AWS account
Create a new EC2 instance
1. Specify which image to use
2. Create & Download a certificate
3. Create and associate an IP address
Connect to the Machine using the AWS certificate
Download the pre-requisites, the installer & run the Installer pre script on Amazon EC2

Step 1: Create an AWS account

Begin by Creating an AWS account → Click Here.
- Follow the steps of the AWS wizard

Step 2: Create a new EC2 Instance

Under the Services dropdown list pick EC2 then click on Launch Instance.
Specify Community AMIs from the left side bar menu, then pick ubuntu.
Pick the instance's Image
1. Select ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-20170721
2. Choose an instance type
  1. t2.medium to deploy SOAJS
  2. t2.large to deploy SOAJS with Analytics
3. In step 6 Configure security groups, add 5 rules:
  1. Type: Custom TCP, Port Range: 22, Source: 0.0.0.0/0
  2. Type: Custom TCP, Port Range: 30080, Source: 0.0.0.0/0
  3. Type: Custom TCP, Port Range: 6443, Source: 0.0.0.0/0
  4. Type: Custom TCP, Port Range: 32017, Source: 0.0.0.0/0
Click Review and Launch so that the new instance starts.
Create & Download a Certificate
1. From the left sidebar click on Key Pairs under NETWORK & SECURITY
2. Create a new Key Pair and give it a name
3. AWS will ask you to download and save the certificate
Create and Associate an IP address
1. In the left menu click on Elastic IPs under NETWORK & SECURITY
2. Click on Allocate new address
3. Link it to the machine instance created

Choose an Image for your Instance

Step 3: Connect to the Machine on your Local Machine

Add the downloaded certificate my-key-pair.pem file of Step 2 to your local .ssh folder:

Connect to the Machine

# copy certificate to your ssh folder
> mv my-key-pair.pem ~/.ssh/my-key-pair.pem
> cd ~/.ssh/
> chmod 400 my-key-pair.pem

# connect to the machine using certificate
> ssh -i my-key-pair.pem ubuntu@machine-ip-address

Step 4: Download the pre-requisites, the installer & run the Installer pre script on Amazon EC2

Once you SSH to the machine, you can download and run the installer pre installation script to get all the dependencies so that cloud deployment works.

Prepare the machine

Download & Run SOAJS Installer pre scripts

# download update apt-get, download nodejs-legacy, npm and zip
> sudo su
> apt-get update && apt install nodejs-legacy npm 

# download installer 
> mkdir -p /opt/soajs/node_modules 
> cd /opt/soajs/node_modules 
> sudo npm install soajs.installer 

# run installer pre script
> cd soajs.installer/scripts/pre 
> sudo /opt/soajs/node_modules/soajs.installer/scripts/pre/kubernetes-linux.sh <%YOUR_CUSTOM_DOMAIN%>

# By default, your cluster will not schedule pods on the master for security reasons.
# If you want to be able to schedule pods on the master, e.g. for a single-machine Kubernetes cluster for development, run
> kubectl taint nodes --all node-role.kubernetes.io/master:NoSchedule-

Grab the kubernetes Secret

Grab the kubernetes secret token by running the below command

Grab the Kubernetes Secret Token

# get kubernetes secrets
> kubectl describe secrets
