Kubernetes allows to reinstall kube-proxy, so the docs for reinstalling kube-proxy told me to launch this command:

Connection refused from pod to pod via service clusterIP

Asked 2022-Jan-16 at 15:05

Something wrong happend with my RPi 4 cluster based on k3sup.

Everything works as expected until yesterday when I had to reinstall master node operating system. For example, I have a redis installed on master node and then some pods on worker nodes. My pods can not connect to redis via DNS: redis-master.database.svc.cluster.local (but they do day before).

It throws an error that can not resolve domain when I test with busybox like:

There was one more thing that was not mentioned. I'm using OpenVPN with NordVPN server list on master node, and use a privoxy for worker nodes.

When you install and run OpenVPN before running kubernetes master, OpenVPN add rules that block kubernetes networking. So, coredns does not work and you can't reach any pod via IP as well.

I'm using RPi 4 cluster, so for me it was good enough to just re-install master node, install kubernetes at first and then configure openvpn. Now everything is working as expected.

It's good enough to order your system units by adding After or Before in service definition. I have VPN systemd service that looks like below:

I'd like to deploy a single app to multiple servers in one time.

I'm using Kubernetes and K3S to easily deploy containers. Basically, I have a master server that I run and multiple servers that are localed in my customers facilities.

Master server was initialized with the following command:

Here there are two different things that we need to consider.

If the requirement is just to run more number of replicas of the application a change to the deployment template in the helm chart or through values you can pass number of minimum replicas need to be working in the cluster.

Reference documentation for deployments

Coming to next thing, if the requirements is just to run application across all the nodes existing in the cluster, Daemonsets is the workload which gives the capability to run across all the existing nodes.

Reference documentation for daemonsets

Again if you are using helm to deploy, appropriate templates for either daemonsets or deployments need to be added or modified based on the existing contents of the helm chart.

There are also different workloads k8s supports so based on requirements they can be picked appropriately.

Since your service is Cluster Ip you can not access the service out of Kubernetes cluster.

You have to expose your service as Node port or Loadbalancer.

however, for testing and debugging locally you can use this command :

Vulnerabilities

No vulnerabilities reported

Install k3sup

k3sup is distributed as a static Go binary. You can use the installer on MacOS and Linux, or visit the Releases page to download the executable for Windows.
You can setup a server and stop here, or go on to use the join command to add some "agents" aka nodes or workers into the cluster to expand its compute capacity. Provision a new VM running a compatible operating system such as Ubuntu, Debian, Raspbian, or something else. Make sure that you opt-in to copy your registered SSH keys over to the new VM or host automatically. Note: You can copy ssh keys to a remote VM with ssh-copy-id user@IP.
Run k3sup:
--cluster - start this server in clustering mode using embedded etcd (embedded HA)
--skip-install - if you already have k3s installed, you can just run this command to get the kubeconfig
--ssh-key - specify a specific path for the SSH key for remote login
--local-path - default is ./kubeconfig - set the file where you want to save your cluster's kubeconfig. By default this file will be overwritten.
--merge - Merge config into existing file instead of overwriting (e.g. to add config to the default kubectl config, use --local-path ~/.kube/config --merge).
--context - default is default - set the name of the kubeconfig context.
--ssh-port - default is 22, but you can specify an alternative port i.e. 2222
--k3s-extra-args - Optional extra arguments to pass to k3s installer, wrapped in quotes, i.e. --k3s-extra-args '--no-deploy traefik' or --k3s-extra-args '--docker'. For multiple args combine then within single quotes --k3s-extra-args '--no-deploy traefik --docker'.
--k3s-version - set the specific version of k3s, i.e. v0.9.1
--ipsec - Enforces the optional extra argument for k3s: --flannel-backend option: ipsec
--print-command - Prints out the command, sent over SSH to the remote computer
--datastore - used to pass a SQL connection-string to the --datastore-endpoint flag of k3s. You must use the format required by k3s in the Rancher docs.
Now try the access:
