  }
  
module "vpc" {
    source        = "../../modules/vpc"
    vpc-location  = "Ohio" # location name as per region
    namespace     = "nextgen-cicd" # namespace
    name          = "vpc" # KEEP IT AS IS
    stage         = "dev" # stage name
    cluster-name  = "nextgen-cicd-dev-eks-cluster" # clustername = namespace-stagename-eks-cluster
}
  
module "eks_workers" {
    namespace    = "nextgen-cicd" # namespace
    stage        = "dev" # stage name
    name         = "eks" # KEEP IT AS IS
    cluster_name = "nextgen-cicd-dev-eks-cluster" # clustername = namespace-stagename-eks-cluster
    key_name     = "nextgen-cicd-key" # MAKE SURE THIS KEY MUST BE CREATED BEFORE RUNNING THIS SCRIPT
}
  
module "eks_cluster" {
    namespace  = "nextgen-cicd" # namespace
    stage      = "dev" # stage name

Docker Networks One of the reasons Docker containers and services are so powerful is that you can connect them together, or connect them to non-Docker workloads. Docker’s networking subsystem is pluggable, using drivers. Several drivers exist by default, and provide core networking functionality: Bridge: The default network driver. If you don’t specify a driver, this is the type of network you are creating. Bridge networks are usually used when your applications run in standalone containers that need to communicate. Host: For standalone containers, remove network isolation between the container and the Docker host, and use the host’s networking directly. host is only available for swarm services on Docker 17.06 and higher. See use the host network. Overlay: Overlay networks connect multiple Docker...
