> > > See https://apisix.apache.org/docs/apisix/next/architecture-design/upstream/, you can refer to the node priority. > > > > > > This should not meet my requirement, my requirement is that under normal circumstances the request will only hit node A and node B. Only if both node A and node B are down, the request will auto go to node C. > > Please read the upstream documentation carefully, this function can be achieved by node priority and active healthy check, there is a very clear demonstration case in the documentation, similar to the following： > > ```shell > curl --location --request PUT 'http://apisix-admin:9180/apisix/admin/routes/failover' \ > --header 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' \ > --header 'Content-Type: application/json' \ > --data-raw '{ > "host": "failover", > "uri": "/*", > "upstream": { > "type": "roundrobin", > "nodes": [ > {"host": "172.30.45.124", "port": 80, "weight": 1}, > {"host": "172.30.45.125", "port": 80, "weight": 1}, > {"host": "172.30.45.126", "port": 80, "weight": 1, "priority": -1} > ], > "checks": { > "active": { > "http_path": "/status/200", > "healthy": { > "interval": 1, > "successes": 1 > }, > "unhealthy": { > "interval": 1, > "http_failures": 1 > } > } > } > }, > "name": "failover" > }' > ``` Thanks for your patience -- This is an automated message from the Apache Git Service.
