Let's assume we have following line in our HA proxy file:
reqrep ^([^\ :]*)\ /api/v1/api-name/(.*) \1\ /staging/path-name/\2
Here is our sample domain:
https://example.com/api/v1/api-name/

The goal here is to rewrite /api/v1/api-name/ to /staging/path-name/ leaving anything else unchanged.

Breaking the Regex and understanding in parts:
There are basically 3 parts in the regex:

Restore Rancher 2 cluster/node agents on clusters

This is an unsupported scenario, see rancher/rancher#14731 when there is an official solution.

When cattle-cluster-agent and/or cattle-node-agent are accidentally deleted, or when server-url/cacerts are changed.

Generate definitions

• Generate API token in the UI (user -> API & Keys) and save the Bearer token
• Find the clusterid in the Rancher UI (format is c-xxxxx), its in the address bar when the cluster is selected

Follow these steps to update the SSL certificate of the ingress in a Rancher High Availability installation or switch from the default self-signed to a custom certificate:

1. Create or update the tls-rancher-ingress k8s secret resource with the new certificate and private key
2. Create or update the tls-ca k8s secret resource with the root CA certificate (only required when using a private CA)
3. Update Rancher installation using Helm CLI
4. Reconfigure Rancher Agents to trust the new CA certificate
