For abilities, you’ve got a jump, you can sprint, and at the start, that’s about it. It’s a very basic game, with its depth mostly revolving around the variety of scenarios that you and the trucks get placed in. Start the proxy: $ kubectl proxy -port=8080 Starting to serve on 127.0.0.Clustertruck has an incredibly simple goal: survive the truck carnage long enough to get to the goal, a flying banner at a set distance away. Let’s use the next Kubernetes manifest: - apiVersion: v1 kind: Service metadata: name: "nginx-service" namespace: "default" spec: ports: - port: 80 type: ClusterIP selector: app: "nginx"Ĭreate the Service: $ kubectl apply -f nginx-svc.yaml service/nginx-service createdĬheck it: $ kk get svc nginx-service NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE nginx-service ClusterIP 172.20.54.138 80/TCP 38s kubectl proxy and Service DNSīecause ClusterIP Service type will be accessible from the cluster only - we can use kubectl proxy to test it - this will open a local TCP port to the API-server and then we can use it to access our NGINX. It can be used, for example, to give access to a caching service to make it accessible for all pods in a namespace. Will open access to an application within a cluster, without access from the world. ExternalName: something like a DNS-proxy - in response to such a Service will return a record taken via CNAME of the record specified in the externalName.LoadBalancer: will create an external Load Balancer (AWS Classic LB), “behind it” automatically will create a NodePort, then ClusterIP and in this way will route traffic from the Load Balancer to a pod in a cluster.NodePort: will open a TCP port on each WorkerNode EС2, “behind it” automatically will create a ClusterIP Service and will route traffic from this TCP port on an ЕС2 to this ClusterIP - such a service will be accessible from the world (obviously, if an EC2 has a public IP), or within a VPC.ClusterIP: the default type, will create a Service resource with an IP address from the cluster's pool, such a Service will be available from within the cluster only (or with kube-proxy).Let’s take a brief overview of each type and then will start with examples:

Pass it to the kubectl port-forward as the first argument, then specify a local port ( 8080), and port on the pod ( 80): $ kubectl port-forward nginx-554b9c67f9-rwbp7 8080:80 Forwarding from :8080 -> 80įrom the local machine check connection to the NGINX pod in the Kubernetes cluster: $ curl localhost:8080 Welcome to nginx! …Ĭool - “It works!”, we have a working pod and now we can use it for our Services.

After we will check that it is working - we can start playing with the network setting from the Kubernetes cluster side.įind the pod’s name: $ kubectl get pod NAME READY STATUS RESTARTS AGE nginx-554b9c67f9-rwbp7 1/1 Running 0 40m To make sure that our pod is up and running and is able to handle incoming connections to the port 80 let use the kubectl port-forward. Okay - it’s the app tag with the nginx value - remember it. Preparationįor tests let’s create a deployment with a pod with NGINX web-server which will accept connections to its port 80: $ kubectl create deployment nginx -image=nginx deployment.apps/nginx createdĬheck: $ kk get deploy nginx NAME READY UP-TO-DATE AVAILABLE AGE nginx 1/1 1 1 53sīecause Services will look for pods by their labels - let’s check which labels this deployment have: $ kubectl get deploy nginx -o jsonpath=’’ map The main goal of the Services in Kubernetes is to provide persistent access to its pods without the necessity to look for a Pod’s IP each time when you’ll recreate such a pod.Īlso, Services can provide a minimal load balancing between similar pods, see Services.

For network communications, Kubernetes presents four Service types - ClusterIP (the default one), NodePort, LoadBalancer, and ExternalName, plus the Ingress resources.
