Creating the Cluster

After creating the Task Definition, we can now create a Cluster.

Creating a Fargate Cluster

Select the Networking only cluster template.

Configure cluster

Enter the cluster name.

Networking

If you don't already have a VPC setup, it's good practice to create one.

An example VPC would have 4 subnets, 2 meant to be private, and 2 meant to be public.

Example:

CIDR block 10.0.0.0/16 Subnet 1: 10.0.0.0/24 Subnet 2: 10.0.1.0/24 Subnet 3: 10.0.2.0/24 Subnet 4: 10.0.3.0/24

You would then navigate to the VPC service and:

1. Create route table for each of the two subnets chosen to be public facing and route 0.0.0.0/0 to the VPC's internet gateway.

2. Create NAT gateways for the public facing subnets.

3. Create route tables for the private subnets and add a 0.0.0.0/0 routes to the NAT gateways.
