By utilizing the concept of Ingress, Kubernetes enables more straightforward load balancing, service discovery, and external connectivity management. Specifically, any Linux distribution that supports snapd. The deployment seems to occur fine but then when I inspect the running services, they cannot seem to access the internet to d Services like Kubernetes, MicroK8S, K3S, expect that the main IP used will not change. kubectl get all --all-namespaces NAMESPACE NAME READY STATUS RESTARTS AGE kube-system pod/metrics-server-7b7db5984b-4mn48 1/1 Running 0 2d2h kube-system pod/calico-node-5ts8c 1/1 Running 1 2d3h kube-system pod/kubernetes-dashboard-7ffd448895-fn9k2 1/1 Running 0 2d2h kube-system Run $ microk8s kubectl get all --all-namespaces and this will give you the ClusterIP:port for the service/kubernetes-dashboard ClusterIP 10. $ sudo microk8s. In this case, you can access the gateway using the service’s node port. It is clear from the above output that External IPs are not assigned to the services yet. You should see an external IP address We need to make a change to enable the Traefik dashboard in Microk8s kubectl by editing the daemon set. 0. kubectl get svc -n ingress.

The flag usage is (listener) IP address that apiserver uses to advertise to members of the cluster (default: node-external-ip/node-ip) This picture shows my computer connect remote server, I test it, raspberry 4B also success. This is a great way, for example, to test out clustered MicroK8s without the microk8s service external-ip stuck on <pending>. microk8s enable host-access Edit Kubernetes Dashboard Service. Dashboard has been exposed on port 31707 (HTTPS). To achieve this, set the value of the externalTrafficPolicy field of the ingress-controller Service spec to Local.

You need to make sure that the source IP address (external-ip assigned by metallb) is preserved. 151, the default address for that VM. NodePorts + Kubeflow + microk8s did not work. Wait until all the microcks services move to a running These IP adresses must be on the same subnet where the cluster is located. 251:19001 192. 31380 did not work for me. 166. 1 and not pod ip 3 Cannot access Microk8s service from browser using NodePort service In the address pools section you've mentioned the allocated IP range as 192. type=="ExternalIP")]. 99. The recommended way for installing MicroK8s is on Linux. The ports will be 5000x and 6000x, with x matching the pod's stateful set identifier, making them unique. Please edit the configmap using the following command, $ kubectl edit configmap config -n metallb-system. Now, to check the status of your MicroK8s node after the installation is finished you can use: sudo microk8s status --wait-ready. 200-192. Enable the Microcks addon on MicroK8s: $ microk8s enable community$ microk8s enable microcks. Set up OIDC to work with Dex. Sorted by: 8. I've enable the following addons. microk8s is running high-availability: no datastore master nodes: 127. We need to alos enable one more additional add-on host-access to enable the access to services running on the host machine via fixed IP address. If you wish We can now install the Kubernetes Dashboard (along with a few other addons) with the command: microk8s enable dns dashboard storage. 0/16. Adding a Loadbalancer. 55 443/TCP .

Bare-metal environments lack this commodity, Depending on the networkPlugin used by your cluster services/pods may be exposed directly on external-ip. You can check the IP address on linux by running ip a or ifconfig . You must can ping it from outside Microk8s machine. microk8s + ingress: ingressed service always resolves to 127. To start MicroK8s run: sudo microk8s start. By default services with Type:LoadBalancer are provisioned with Classic Load Balancers automatically. If you will use Ingress you have to remember to enable ingress and dns addons in Microk8s.
