Guide to create public load balancer

Make Environment Publicly Accessible using AWS LB Configuration

This document provides step-by-step instructions to make environment publicly accessible without wire guard configuration. Generally, all environments are privately accessible using wire guard configuration.

Notes:

The naming conventions may vary depending on the environment and this documentation will be applicable when using an AWS load balancer.

Create Target Group for external-http

  1. In the EC2 dashboard, under the Load Balancing section, select Target Groups from the menu.
  2. Click the Create Target Group button to create a new Target Group.
  3. Configure Target Group
    • Choose target type - IP addresses
    • Target Group name - openg2p-<envname>-external-http
    • Protocol : Port - TCP : 30080
    • VPC - Select the VPC in which the instances are located
    • Health check protocol : Path : Port (Traffic Port) - HTTP : /healthz/ready : 30521
  4. Register Targets
    • After configuring the Target Group, click the Next button.
    • Select the targets (instances) to register with the Target Group.
    • Click the Add to registered button to add the selected targets to the Target Group.
  5. Review the configuration settings for the Target Group. After verification, click the Create Target Group button to create the Target Group.
  6. Once the Target Group is created, make a note of the Amazon Resource Name (ARN) of the newly created Target Group. This ARN is required when you configure Load Balancers or other services that use the Target Group.

Create Target Group for external-httpsredirect

  1. To create a Target Group for "external-httpsredirect," follow the same steps mentioned above. Only for the Configure Target Group section, use the following configurations.
    • Choose target type - IP addresses
    • Target Group name - openg2p-<envname>-ext-httpsredirect
    • Protocol : Port - TCP : 30081
    • VPC - Select the VPC in which the instances are located.
    • Health check protocol : Path : Port (Overide) - HTTP : /healthz/ready : 30521

Create a Target Group for PostgreSQL

  1. For PostgreSQL, there is no need to create a Target Group (TG). Instead, create a record with the name internal.sandbox-name and map the Internal NLB DNS name of the environment to it in AWS Route53.

Create external network Load Balancer

  1. In the EC2 dashboard, click the Load Balancers tab and then click Create Load Balancer.

  2. Choose Load Balancer Type as Network Load Balancer.

  3. Configure Load Balancer Settings

    • Create NLB with name - openg2p-<envname>-external

    • Select VPC - Select the VPC and region in which the instances are located

    • Select Security Group - Select the Security Group in which the instances are located

      Notes:

    Click here to create Security Group, if required

    • Configure Routing - Define Target Groups to route traffic to specific instances

      • Listeners and routing Protocol : Port : Default action

        Notes:

      Below the default action, select the Target Groups already created from the above steps.

      • TLS : 443 : openg2p-<envname>-external-http

      • TCP : 80 : openg2p-<envname>-ext-httpsredirect

      • Select ACM certificate as per environment domain name.

        Notes:

      Click here to create ACM certificate, if required.

    • Review the configuration settings and create the Load Balancer.

    • Do mapping on AWS Route53.
