My dependence on helm means that i would typically expect it to update running CRDs, but helm doesn't support upgrading or deleting CRDs at the moment. I'm interested, how do you install and update your CRDs? submitted by /u/Far_Sandwich_3329 [visit reddit] [comments ..read more

Hi, I do try to set up a cluster of 5 VMs (2x master + 3x worker). During set up of a cluster I do recive an error when using command microk8s join 11.22.33.44:25000/token/token --worker When joining cluster as a master (without --worker flag) there is no problems and I do have succesful join Waiting for this node to finish joining the cluster. .. .. .. .. Successfully joined the cluster. I had found an Issue on github related to the error Joining a cluster not possible in v1.24 #3225 and I had proceed to add all of related IPs to /etc/hosts as suggested but still with the same output ..read more

Hi everyone, Went through a practice exam for the CKS , recently Had a couple of a questions that I wasn't able to resolve them . First one was about unmounting api cred token for a service account , despite founding a very clear documentation and was just about adding a new line under the metadata but it wasn't working . Any idea to resolve it ? 2nd queation is about disabling anonymous auth for kubelet . How to do that ? I was looking for the config file of kubelet and didn't know should I include it there or in the manifest file of api server . Your inputs is highly appreciated . submitte ..read more

I sometimes run into networking issues inside kubernetes where I need to look deeper to see why a pod or node isn't doing what I want. This often involves nslookup/tcpdump/ngrep and other tool that have to run on the node itself. One solution is to SSH to the node then install the correct debugging tools. This can be difficult especially if the node itself is a bare or unfamiliar OS. Netshoot is a docker image that contains a large number of helpful debugging binaries already installed. Combining this with a `nodeSelector` and `hostNetworking`, I can easily get a debuggable container into a n ..read more

Hey Folks. I am looking for tools which could help us with our local development. The scenario: Each developer has a local k8s cluster on odcker desktop which is managed by Argocd. Like this we can have the local setup as close as possible to prod. We tried several tools to develop against/with this local cluster: Telepresence - Often 502 errors, no multiple namespaces possible Bridge To Kubernetes (currently our favourite) Nocalhost - poor performance, not the best docs Although B2K works most of the time, it does not have the best expirence and does not come along very good with ArgoCD (d ..read more

So ... I'm looking into deploying Kubernetes on a single node because there are a couple of open source scripts I really want to install on a server but they all only play nice with Helm + Kubernetes. I tried out Rancher Desktop and it was sort of what I was looking for but still felt a little overpowered for such a modest deployment. I've played around with the various frameworks that support one node like microk8s etc. I would like to either host my own deployment web UI or have one that can coexist with the deployment node itself. Anything in the realm of open source (or simplified IaaS an ..read more

I'm running RKE2 on a cluster of virtual machines and we received a request from our network operations team to rename all of the clusters to something more descriptive. This is my first time deploying any RKE2 application and it took me forever to get it working. I'm also running a gluster filesystem and am afraid that doing this on an already working deployment of our software will just break everything. any pointers on how to do this while not incurring serious downtime or needing to start from scratch? submitted by /u/dsp3000 [visit reddit] [comments ..read more

Soon we will do audit of 2 on-premise okd clusters . They contain things like gitlab, jenkins, hashicorp vault, grafana stack, nginx ingress etc. After all security, backups, resources and other things checks also we will have to perform the upgrade of the cluster to the newest version. It will be preceded with cluster services impact analysis. Again: CLUSTER services, not some external things like grafana stack. Cloud k8s clusters usually don't need that, you just bump cluster version. But on on-premise cluster you need to do it. How to approach it? How to estimate it in mandays? submitted ..read more

Hey eyerone, I got a big problem. We have 2 different networks in my company, one for "internal" stuff and one for "external" stuff. Now I have 2 K8S-Clusters, one in each network. I have a Gitlab in my "internal" network and I need to deploy stuff to my "external" network from my Gitlab instance. I am using gitlab-agent for my "internal" network but I can not use it for my "external" because it´s forbidden to open a connection from "external" -> "internal". Since gitlab-agent is a bidirectional connection where the agent is connecting to a Websocket-connection (in our case) deployed on Gi ..read more
