If you are not familiar with the kubectl command, check out my article Getting Started with kubectl.

There are different types of services, such as ClusterIP, NodePort and LoadBalancer. A service is used to forward requests onto one or more pods.

• The ClusterIP service is only accessible within the Kubernetes cluster
• The NodePort service is accessible within your network
• The LoadBalancer makes the service accessible externally, over the internet.

The kubectl get services command can be used to list the services in the currently selected project / namespace.

TIP

The -A or --all-namespaces flag can be used to list the services in every project / namespace.

The -n or --namespace flag can be used to list the services in a certain project / namespace.

~]# kubectl get services
NAME               TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
myService001       ClusterIP      172.30.164.121   <none>        27017/TCP       114d
myService002       LoadBalancer   172.30.166.121   <pending>     8443:30444/TCP  114d

The kubectl get service command followed by the name of a service can be used to display an individual service.

~]# kubectl get service myService001
NAME               TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)     AGE
myService001       ClusterIP   172.30.164.121   <none>        27017/TCP   114d

The kubectl describe service command can be used to show the details of the service.

~]$ kubectl describe service myService001
