Resolution

The network requirements for Rancher Hosted Prime are going to depend on your use cases. The following is a list of common uses cases and what is required:

  • To access the Rancher UI or API, you must have outbound TCP/443 connectivity to Rancher Hosted Prime.
  • All downstream/managed clusters require outbound TCP/443 connectivity to Rancher Hosted Prime.
  • If you are creating a node driver based cluster, Rancher Hosted Prime will need TCP/22 (SSH) connectivity to each node for the initial provisioning. Additionally, Rancher Hosted Prime will need connectivity to the orchestration API, for example, the vSphere API.
  • For authentication provider integration, Rancher Hosted Prime will require connectivity to the authentication provider's endpoint. Generally, no networking setup is needed if using a SaaS authentication provider such as Azure Active Directory, Okta, or GitHub.

More detailed documentation for networking requirements can be found in Rancher's port requirements docs.
