Networking Requirements

Overview​

Components deployed inside locally-hosted infrastructure need to communicate with other components over the network. This page provides a list of ports that need to be open for the communication to work properly.

Ports used by TIM v5​

  • Kubernetes -> PostgreSQL
    • 5432 TCP
  • Kubernetes -> Kubernetes (communication between all pods running in tim-platform namepsace)
    • 80 TCP+UDP
    • 443 TCP+UDP
    • 5672 TCP+UDP
    • 15672 TCP+UDP
    • 5000 TCP+UDP
    • 8000 TCP+UDP
    • 8071 TCP+UDP
    • 8073 TCP+UDP
    • 8080 TCP+UDP
  • Kubernetes -> Internet (this traffic goes through the internet!)
  • Administrator's PC -> Kubernetes
    • 443 TCP+UDP
    • 6443 TCP
    • 2379 TCP
    • 2380 TCP
  • Administrator's PC -> PostgreSQL
    • 5432 TCP
  • Internet -> Kubernetes
    • (Optional) 443 TCP

Note: Administrator's PC is a machine from which TIM v5 installation and management is happening. It can be a developer's PC or a virtual machine in the cloud (jump server).

Kubernetes features used by TIM v5​

TIM v5 requires DNS Resolution feature to be enabled and running in the Kubernetes cluster. The following command can be used to check if DNS is enabled and running: kubectl get pods --namespace=kube-system -l k8s-app=kube-dns. Please note that there should be one coredns pod running on each node in the cluster.
