When you are using api gateway in OpenWhisk, try this command:
wsk api list -i
If you get blow error, it means you didn't set up API Gatway completely.
$ ./wsk -i api list
error: Unable to obtain the API list: The requested resource does not exist. (code 128343)
Try below steps to install the artifacts on OpenWhisk which is used by API Gateway.
- Clone the whole incubator-openwhisk in your disk:
git clone https://github.com/apache/incubator-openwhisk.git
Set environment OPENWHISK_HOME to this folder by:
export OPENWHISK_HOME=<your_incubator_openwhisk_folder>
- Get the IP address and port of apigateway and redis, which will be used in the following steps by:
kubectl get svc -n openwhisk
- Configure your apigateway to make sure apigateway can access redis (Need to verify if this step is nesseary).
Try below command, find
name: REDIS_HOST, change the value fromredis.openwhiskto the IP address of redis.
kubectl edit deployment apigateway -n openwhisk
- Edit file
$OPENWHISK_HOME/ansible/roles/routemgmt/files/installRouteMgmt.sh, find below variables and set to:
GW_USER=""
GW_PWD=""
GW_HOST_V2="http://10.0.0.116:9000/v2"
GW_HOST_V2 is the IP address and port of apigateway.
- Run
$OPENWHISK_HOME/ansible/roles/routemgmt/files/installRouteMgmt.shby
./installRouteMgmt.sh <AUTH> <APIHOST> <NAMESPACE> <WSK_CLI>
e.g.
./installRouteMgmt.sh 789c46b1-71f6-4ed5-8c54-816aa4f8c502:abczO3xZCLrMN6v2BKK1dXYFpXlPkccOFqm12CdAsMgRU4VrNZ9lyGVCGuMDGIwP 9.111.141.85:32437 /whisk.system /usr/local/bin/wsk
After that, you can try wsk api list -i and check if you API gateway is installed completely.
If you want to access the URL managed by API Gatway exteranally from Kubernetes, you have to make sure the apigateway service has NodePort configured.
kubectl edit svc apigateway -n openwhisk -oyaml
You need to change the type: ClusterIP to type: NodePort.
