2020-10-27 09:43:45 UTC - Jiang PengCheng: hello whiskers, have you met below nginx error logs on openwhisk for k8s? ```2020/07/24 09:56:48 [crit] 28#28: *58705 connect() to x.x.x.x:8080 failed (99: Cannot assign requested address) while connecting to upstream, client: y.y.y.y, server: ~^(?<namespace>[0-9a-zA-Z-]+)\.$, request: "POST /api/v1/namespaces/whisk.system/actions/hello1?result=true&blocking=true HTTP/1.1", upstream: "<http://x.x.x.x:8080/api/v1/namespaces/whisk.system/actions/hello1?result=true&blocking=true>", host: "z.z.z.z"``` I got such error logs when did a benchmark and then it returned lots of error responses seems it's caused by the nginx's upstream servers configuration? https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1603791825161100 ---- 2020-10-27 09:49:26 UTC - Jiang PengCheng: after I changed below configuration in nginx: ```resolver coredns.kube-system; set $controllers <http://openwhisk-controller.jiangpengcheng.svc.example.com|openwhisk-controller.jiangpengcheng.svc.example.com>;``` to ``` upstream controllers { # Mark the controller as unavailable after fail_timeout seconds, to not get any requests during restart. # Otherwise, nginx would dispatch requests when the container is up, but the backend in the container not. # From the docs: # "normally, requests with a non-idempotent method (POST, LOCK, PATCH) are not passed to # the next server if a request has been sent to an upstream server" server <http://openwhisk-controller-0.jiangpengcheng.svc.example.com;:8080|openwhisk-controller-0.jiangpengcheng.svc.example.com;:8080> fail_timeout=60s; server <http://openwhisk-controller-1.jiangpengcheng.svc.example.com;:8080|openwhisk-controller-1.jiangpengcheng.svc.example.com;:8080> fail_timeout=60s; server <http://openwhisk-controller-2.jiangpengcheng.svc.example.com;:8080|openwhisk-controller-2.jiangpengcheng.svc.example.com;:8080> fail_timeout=60s; keepalive 512; }``` then errors were gone https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1603792166163600 ---- 2020-10-27 19:20:31 UTC - Michele Sciabarra: @Erez Hadad in any case I am willing to contribute work to help adding this feature in mainstream, and I believe also @Rodric Rabbah and @Dragos Dascalita Haut are interested in the idea https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1603826431163800?thread_ts=1603551396.137600&cid=C3TPCAQG1 ---- 2020-10-27 19:50:24 UTC - Erez Hadad: This is good news. In the absence of my peer's responses, I will try to find the repository and get you access to available code/documentation https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1603828224164000?thread_ts=1603551396.137600&cid=C3TPCAQG1 ---- 2020-10-27 20:18:35 UTC - parichehr vahidinia: Hi. I installed _openwhisk_ via *docker-compose* and the following commands were executed successfully `make docker-pull` , `make docker-build` and `make run`. but when I run the `make hello-world` , I get the following error: `Error invoking the web action` `make: *** [Makefile:416: hello-world] Error 1` . Also when I run `docker ps` command, _nginx_ is not in the containers list. https://openwhisk-team.slack.com/archives/C3TPCAQG1/p1603829915167700 ----
