I install istio 1.10 and kubenetes v1.19.0 with profile
Base on the document: service-entry, use the
sleep pod as client and arbitary web service on vm serving at port 9000.
I create a service entry for this web service on vm :
apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: name: sonarqube namespace: external spec: hosts: - "cicd.sonar.com" location: MESH_INTERNAL ports: - number: 9000 name: http protocol: HTTP resolution: STATIC endpoints: - address: 192.168.10.98
sleep pod in namespace
[root@apiserver sleep]# kubectl exec -it sleep-79f64648b5-j4bvw -n external -c sleep -- /bin/sh / $ curl cicd.sonar.com:9000 curl: (6) Could not resolve host: cicd.sonar.com
apparently, the dns is not working. but I don’t know how to debug it?
I also notice that smart dns is available on since v1.8.0, how to let service running in or out of mesh
access each other using service dns ?
