If it is your private k8s cluster  MetalLB would be a better fit  Below are the steps   Step 1  Install MetalLB in your cluster  kubectl apply -f https   raw githubusercontent com metallb metallb v0 9 3 manifests namespace yaml kubectl apply -f https   raw githubusercontent com metallb metallb v0 9 3 manifests metallb yaml   On first install only kubectl create secret generic -n metallb-system memberlist --from-literal secretkey    openssl rand -base64 128     Step 2  Configure it by using a configmap  apiVersion  v1 kind  ConfigMap metadata    namespace  metallb-system   name  config data    config        address-pools      - name  default       protocol  layer2       addresses        - 172 42 42 100-172 42 42 105  Update this with your Nodes IP range    Step 3  Create your service to get an external IP  would be a private IP though    FYR   Before MetalLB installation    After MetalLB installation

If you are using minikube then run commands below from terminal      minikube ip   172 17 0 2    then    curl http   172 17 0 2 31245 or simply   curl http     minikube ip  31245

You can patch the IP of Node where pods are hosted   Private IP of Node     this is the easy workaround    Taking reference with above posts   Following worked for me    kubectl patch service my-loadbalancer-service-name   -n lb-service-namespace   -p    spec     type    LoadBalancer    externalIPs    xxx xxx xxx xxx Private IP of Physical Server - Node - where deployment is done

If you are not using GCE or EKS  you used kubeadm  you can add an externalIPs spec to your service YAML  You can use the IP associated with your node s primary interface such as eth0  You can then access the service externally  using the external IP of the node        spec    type  LoadBalancer   externalIPs    - 192 168 0 10

If you are not on a supported cloud  aws  azure  gcloud etc    you can t use LoadBalancer without MetalLB https   metallb universe tf  but it s in beta yet

Adding a solution for those who encountered this error while running on amazon-eks  First of all run  kubectl describe svc  lt service-name gt   And then review the events field in the example output below  Name                      some-service Namespace                 default Labels                     lt none gt  Annotations               kubectl kubernetes io last-applied-configuration                                quot apiVersion quot   quot v1 quot   quot kind quot   quot Service quot   quot metadata quot    quot annotations quot      quot name quot   quot some-service quot   quot namespace quot   quot default quot    quot spec quot    quot ports quot     quot port quot  80     Selector                  app some Type                      LoadBalancer IP                        10 100 91 19 Port                       lt unset gt   80 TCP TargetPort                5000 TCP NodePort                   lt unset gt   31022 TCP Endpoints                  lt none gt  Session Affinity          None External Traffic Policy   Cluster Events    Type     Reason                  Age        From                Message   ----     ------                  ----       ----                -------   Normal   EnsuringLoadBalancer    68s  service-controller  Ensuring load balancer   Warning  SyncLoadBalancerFailed  67s  service-controller  Error syncing load balancer  failed to ensure load balancer  could not find any suitable subnets for creating the ELB  Review the error message  Failed to ensure load balancer  could not find any suitable subnets for creating the ELB  In my case  the reason that no suitable subnets were provided for creating the ELB were  1  The EKS cluster was deployed on the wrong subnets group - internal subnets instead of public facing       By default  services of type LoadBalancer create public-facing load balancers if no service beta kubernetes io aws-load-balancer-internal   quot true quot  annotation was provided   2  The Subnets weren t tagged according to the requirements mentioned here  Tagging VPC with  Key  kubernetes io cluster yourEKSClusterName Value  shared  Tagging public subnets with  Key  kubernetes io role elb Value  1

There are three types of exposing your service Nodeport ClusterIP LoadBalancer When we use a loadbalancer we basically ask our cloud provider to give us a dns which can be accessed online Note not a domain name but a dns  So loadbalancer type does not work in our local minikube env

User · Answer

The LoadBalancer ServiceType will only work if the underlying infrastructure supports the automatic creation of Load Balancers and have the respective support in Kubernetes  as is the case with the Google Cloud Platform and AWS  If no such feature is configured  the LoadBalancer IP address field is not populated and still in pending status   and the Service will work the same way as a NodePort type Service

If you are using Minikube  there is a magic command     minikube tunnel   Hopefully someone can save a few minutes with this   Reference link https   minikube sigs k8s io docs handbook accessing  using-minikube-tunnel

User · Answer

It looks like you are using a custom Kubernetes Cluster  using minikube  kubeadm or the like   In this case  there is no LoadBalancer integrated  unlike AWS or Google Cloud   With this default setup  you can only use NodePort or an Ingress Controller   With the Ingress Controller you can setup a domain name which maps to your pod  you don t need to give your Service the LoadBalancer type if you use an Ingress Controller

Following  Javier s answer  I have decided to go with  patching up the external IP  for my load balancer       kubectl patch service my-loadbalancer-service-name   -n lb-service-namespace   -p    spec     type    LoadBalancer    externalIPs    192 168 39 25        This will replace that  pending  with a new patched up IP address you can use for your cluster   For more on this  Please see karthik s post on LoadBalancer support with Minikube for Kubernetes   Not the cleanest way to do it  I needed a temporary solution   Hope this helps somebody
