OpenWhisk Action calls may consume time on pulling the runtime image and starting the container, so if you set the value too small, you may cause a large number of requests to fail. OpenWhisk supports timeouts ranging from 1ms to 60000ms, and we recommended to set at least 1000ms or more. + +::: + +## Example + +First, you need to run the OpenWhisk environment. Here is an example of using OpenWhisk standalone mode. + +```shell +docker run --rm -d \ + -h openwhisk --name openwhisk \ + -p 3233:3233 -p 3232:3232 \ + -v /var/run/docker.sock:/var/run/docker.sock \ + openwhisk/standalone:nightly +docker exec openwhisk waitready +``` + +Then, you need to create an Action for testing. + +```shell +wsk property set --apihost "http://localhost:3233"; --auth "23bc46b1-71f6-4ed5-8c54-816aa4f8c502:123zO3xZCLrMN6v2BKK1dXYFpXlPkccOFqm12CdAsMgRU4VrNZ9lyGVCGuMDGIwP" +wsk action update test <(echo 'function main(){return {"ready":true}}') --kind nodejs:14 +``` + +Here is an example of creating a Route and enabling this plugin + +```shell +curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' +{ + "uri": "/hello", + "plugins": { + "openwhisk": { + "api_host": "http://localhost:3233";, + "service_token": "23bc46b1-71f6-4ed5-8c54-816aa4f8c502:123zO3xZCLrMN6v2BKK1dXYFpXlPkccOFqm12CdAsMgRU4VrNZ9lyGVCGuMDGIwP", + "namespace": "guest", + "action": "test" + } + } +}' +``` + +Finally, you can send a request to this route and you will get the following response. And you can disable it by removing the openwhsik plugin from the route. + +```json +{"ready": true} +``` + +## Notice + +When you need to submit data, you need to use a request body in JSON format. Also you should pay attention to the request body size, request body exceeding the `client_body_buffer_size` setting will be discarded completely, its size defaults to 8KiB.
