Can not call web action from browser #655

Closed asok1 closed 3 years ago

asok1 commented 3 years ago

How can I call a web action from my browser, when my OpenWhisk deployment is on a company sandbox server?

I have an OpenWhisk deployment setup on a company sandbox server using this guide: Deploying OpenWhisk on kind. The server is running CentOS 7. I created a web action and I am able to call with curl -k https://apiHostName:apiHostPort/api/v1/web/guest/demo/hello?name=myName where apiHostName and apiHostPort are the values defined in mycluster.yaml. However, trying to access the above url from my browser returns ERR_CONNECTION_TIMED_OUT. 

[root[DEV]@vx3a27 wskcluster]# kubectl -n openwhisk get svc
NAME               TYPE        CLUSTER-IP      EXTERNAL-IP    PORT(S)                      AGE
owdev-apigateway   ClusterIP   10.96.9.60      A.B.C.D        8080/TCP,9000/TCP            6d1h
owdev-controller   ClusterIP   10.96.104.180   <none>         8080/TCP                     6d1h
owdev-couchdb      ClusterIP   10.96.40.104    <none>         5984/TCP                     6d1h
owdev-kafka        ClusterIP   None            <none>         9092/TCP                     6d1h
owdev-nginx        NodePort    10.96.84.3      A.B.C.D        80:31486/TCP,443:31001/TCP   6d1h
owdev-redis        ClusterIP   10.96.84.177    <none>         6379/TCP                     6d1h
owdev-zookeeper    ClusterIP   None            <none>         2181/TCP,2888/TCP,3888/TCP   6d1h

I have tried setting the external API of both my nginx and apigateway services as seen above, where A.B.C.D is the IP of my sandbox obtained with ifconfig. Running both curl -k and the browser with A.B.C.D yields ERR_CONNECTION_REFUSED.

What else can I try to get this to work?

Are you able to curl against the nginx IP?

You should get something like this:

$ curl 10.107.131.27
{"api_paths":["/api/v1"],"description":"OpenWhisk","limits":{"actions_per_minute":60,"concurrent_actions":100,"max_action_duration":360000,"max_action_logs":1048576,"max_action_memory":1073741824,"min_action_duration":100,"min_action_logs":0,"min_action_memory":536870912,"sequence_length":50,"triggers_per_minute":240},"runtimes":{...},"support":{"github":"https://github.com/apache/openwhisk/issues","slack":"http://slack.openwhisk.org"}}

Since the error is CONNECTION_REFUSED rather than CONNECTION_TIMEDOUT, I suppose your ow deployment is not complete. There might be some failures in some pods. It seems nginx cannot connect to controllers.

asok1 commented 3 years ago

No, I get this: 

# curl 10.96.84.3
curl: (7) Failed connect to 10.96.84.3:80; Connection refused

Also, looking into the pods I found an error in the owdev-tests-smoketest pod:

Note that the cluster was reset so the IPs have changed and the external IP was deleted but the functionality is still the same.

I recommend looking into controller or nginx logs as you even cannot connect to it.
