What are the networking requirements for using Hosted Rancher?
The network requirements for Hosted Rancher 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 Hosted Rancher.
- All downstream/managed clusters require outbound TCP/443 connectivity to Hosted Rancher.
- If you are created a node driver based cluster, Hosted Rancher will need TCP/22 (SSH) connectivity to each node for the initial provisioning. Additionally, Hosted Rancher will need connectivity to the orchestration API, for example, the vSphere API.
- For authentication provider integration, Hosted Rancher will require connectivity from Hosted Rancher to the authentication provider's endpoint. Generally no networking setup is needed if using a SaaS authentication provider such as Azure AD, Okta, or GitHub.
More detailed documentation for networking requirements can be found in Rancher's port requirements docs.
