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

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

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

Use NodePort    kubectl run user-login --replicas 2 --labels  quot run user-login quot  --image kingslayerr teamproject version2  --port 5000    kubectl expose deployment user-login --type NodePort --name user-login-service    kubectl describe services user-login-service   Note down the port    kubectl cluster-info   IP- gt  Get The IP where master is running  Your service is accessible at  IP   port

Delete existing service and create a same new service solved my problems  My problems is that the loading balancing IP I defines is used so that external endpoint is pending  When I changed a new load balancing IP it still couldn t work  Finally  delete existing service and create a new one solved my problem

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

I created a single node k8s cluster using kubeadm  When i tried PortForward and kubectl proxy  it showed external IP as pending     kubectl get svc -n argocd argocd-server NAME            TYPE           CLUSTER-IP      EXTERNAL-IP   PORT S                       AGE argocd-server   LoadBalancer   10 107 37 153    lt pending gt      80 30047 TCP 443 31307 TCP   110s   In my case I ve patched the service like this   kubectl patch svc  lt svc-name gt  -n  lt namespace gt  -p    spec     type    LoadBalancer    externalIPs    172 31 71 218        After this  it started serving over the public IP    kubectl get svc argo-ui -n argo NAME      TYPE           CLUSTER-IP     EXTERNAL-IP     PORT S         AGE argo-ui   LoadBalancer   10 103 219 8   172 31 71 218   80 30981 TCP   7m50s

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

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

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

Check kube-controller logs  I was able to solve this issue by setting the clusterID tags to the ec2 instance I deployed the cluster on

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

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
