            MicroK8s containers unable to start. All pods stuck on "ContainerCreating" state. Ubuntu 20.10 RP4
            Asked 2021-May-10 at 11:12

            I've been Googling and going through logs to try and solve this, but I can't seem to get microk8s to work on my Raspberry Pi, running Ubuntu 20.10

            I snap install v1.15 sudo snap install microk8s --classic --channel=1.15/stable

            I can confirm that microk8s.status returns that it is running. kubectl get nodes --namespace kube-system returns:

            ANSWER

            Answered 2021-May-10 at 11:12

            Found the issue was with microk8s, specifically containerd not working with squashFS filesystem with overlay.

            The reason for my Ubuntu install using SquashFS was that I was using Berryboot to support multiple OS installations.

            I switched to Pinn, which supports ext4 filesystem, which works with containerd and reinstalled Ubuntu 20.04.

            After installing microk8s, the node starts running and containers are all now running correctly.

            It looks like the kubernetes-dashboard's serviceaccount doesn't have access to all kubernetes resources (in particular, it can't access the metric server service).

            To fix this you should create a new ServiceAccount for the dashboard and give it more permissions.

            Here's one that I found on another similar post (be careful since it will give admin privileges to the dashboard, and whoever uses it will be able to destroy/create new or existing resources on your kubernetes cluster):

            Looks like you created the secret my-secret in default namespace but the deployment app-config-service is running in kube-system namespace and hence can not refer to my-secret using imagePullSecrets. Creating the secret my-secret in kube-system namespace should solve the issue.

            Why are IP adresses in GKE for fluentd / kube-proxy/prometheus equal to node addresses

            ANSWER

            Answered 2020-Apr-28 at 17:40

            This is because pods such as kube proxy , Fluentd, Prometheus are running in host network directly via hostNetwork: true. You can describe those pods and verify that hostNetwork: true is present.

            Now coming to the point why these pods need to run in host network in the first place , kube proxy needs access to host's IP tables, prometheus collects metrics and Fluentd collects logs from the host system.

            You can just deploy a sample pod such as nginx with hostNetwork: true and it will get node IP.If you remove hostNetwork: true it will get IP from pod CIDR range.

            Nothing is frozen - the command for port-forward is running in the foreground. If you have setup the service properly with the right port number everything should be working fine.

            Try running the same as a background process, by adding & at the end.

            microk8s kubectl port-forward -n kube-system service/kubernetes-dashboard 10443:443 &

            I came with a solution, it's not the best or straight forward but at least it's working. My slave is connected! INFO: Connected

            So, I edited the jenkins-agent service and from type: ClusterIP I changed to type: LoadBalancer. That gave me a new fresh loadbalancer and after I decided to add the port 8080 because in the service yaml file it's using the same selector as in jenkins service.

            Geting custom metrics from Kubernetes pods
            Asked 2020-Mar-27 at 19:43

            I was looking into Kubernetes Heapster and Metrics-server for getting metrics from the running pods. But the issue is, I need some custom metrics which might vary from pod to pod, and apparently Heapster only provides cpu and memory related metrics. Is there any tool already out there, which would provide me the functionality I want, or do I need to build one from scratch?

            ANSWER

            Answered 2018-Aug-23 at 09:44

            What you're looking for is application & infrastructure specific metrics. For this, the TICK stack could be helpful! Specifically Telegraf can be set up to gather detailed infrastructure metrics like Memory- and CPU pressure or even the resources used by individual docker containers, network and IO metrics etc... But it can also scrape Prometheus metrics from pods. These metrics are then shipped to influxdb and visualized using either chronograph or grafana.

            if you use deployments, for sake of human operators you'll find your pods names as -<[0-9a-z]{5}> where replicaset is -. For kubernetes it self, naming of pods is irrelevant.
