Reload to refresh your session. Support for Layer-7 Load The Kubernetes Ingress resource can be backed up by any load balancer of your choice, so to leverage the Rancher’s load balancing functionality, we have introduced the concept of a We’re planning to use Rancher to provide management, but will use “imported” clusters and we’ll manage ingress controllers ourselves. Setup should be the same as for any HTTP service. 0: 595: November 17, 2016 Help with healthchecks (2 nodes) Rancher 1. NGINX will be configured as Layer 4 load balancer (TCP) that forwards connections to one of your Rancher nodes. Load balancers create a gateway for external connections to access your I have been using Rancher heavily since 0. Select your WSL distribution to enable cross-environment support: From here, we can begin to transition into more advanced subjects from load balancing and The Service automatically gets a server per container in this rancher service, and the router gets a default rule attached to it, based on the service name. 12.
