Kubernetes - Calling Microservice by Service Name

Asked 2021-Feb-18 at 12:42

I have two Microservices deployed on K8S cluster (Locally on 3 VMs - 1 Master and 2 Worker Nodes):
1- currency-exchange Microservice
2- currency-conversion Microservice

I am trying to call currency-exchange Microservice from currency-conversion by using service name :
http:///currency-exchange:8000.

It returns error as below:
{"timestamp":"2021-02-17T08:38:25.590+0000","status":500,"error":"Internal Server Error","message":"currency-exchange executing GET http://currency-exchange:8000/currency-exchange/from/EUR/to/INR","path":"/currency-conversion/from/EUR/to/INR/quantity/10"}

ANSWER

Answered 2021-Feb-18 at 12:42

It looks to me that you have incorrectly setup your CNI overlay network. I checked your previous question to verify node's ip address and to me it looks that your pod network overlap with your host network:

The Kubernetes pod-network-cidr is the IP prefix for all pods in the Kubernetes cluster. This range must not clash with other networks in your VPC

The Kubernetes pod network documentation describes this as well:

Take care that your Pod network must not overlap with any of the host networks: you are likely to see problems if there is any overlap. (If you find a collision between your network plugin's preferred Pod network and some of your host networks, you should think of a suitable CIDR block to use instead, then use that during kubeadm init with --pod-network-cidr and as a replacement in your network plugin's YAML).

This is also mentioned in calico instructions when creating a cluster:

Note: If 192.168.0.0/16 is already in use within your network you must select a different pod network CIDR, replacing 192.168.0.0/16 in the above command.

PS. You can always wget curl from here.

ANSWER

Answered 2020-Jul-06 at 04:38

You cannot access your service currency-conversion because of the firewall rules. Your requests are going to be blocked by default by VPC Firewall. To allow traffic to your currency-conversion service you can either:

Create a firewall rule that will allow the traffic to enter (you will be able to $ curl NODE_IP:NODE_PORT):
- $ gcloud compute firewall-rules create test-node-port --allow tcp:NODE_PORT
Create a service of type LoadBalancer which will allocate public IP address and create a forwarding rule for access (you've already done it with currency-exchange):
- $ kubectl expose deployment NAME --type=LoadBalancer --port=PORT-CONTAINER-IS-LISTENING-ON

You can read more about Kubernetes services here:

Cloud.google.com: Kubernetes Engine: How to: Exposing apps - specific to GKE
Cloud.google.com: Kubernetes Engine: Concepts: Service
Kubernetes.io: Services networking: Service

Disclaimer!
$ gcloud compute firewall-rules create test-node-port --allow tcp:node-port

Above rule will allow traffic to ALL instances in the default network.

For more secure approach you can use the below rule:

ANSWER

Answered 2020-May-21 at 17:45

I'm surprised you're not receiving an exception at the start of runtime. The ExchangeServiceRepository reference is null. You need to add the @Repository annotation to the type ExchangeServiceRepository. Spring is likely unable to autowire this Bean because it's not annotated as a Repository (DAO) which at it's core is a @Component.
