Hello, We have a use case to create static pv with ReadWriteMany acces mode. We are looking at the longhorn docs https://longhorn.io/docs/1.4.2/advanced-resources/rwx-workloads/, have few questions

- can you share the sample yaml to create static pv ( we have requirement to attach the same pv with many pods/clients ) and 2nd question: A 90 second fail over is a deal breaker for us, what is the better option to create RWX pv?

Hello , I am using rancher for high availability k8s setup. I am having 3 master and 2 worker node. I want to know how traffic os flowing for apiserver when i am sending it using kubectl? I know first ot will go to rancher as my kubeconfig is having rancher url but i want to know what happens after rancher? Will it go round robin or how is it works? How can i test it or find out? Any suggestions ?

Hello, I've installed rancher on RKE1 successfully, but while trying to reproduce following exactly the same process, the dashboard is sometimes not available (Getting This site can’t be reached... took too long to respond.) How can I make sure the installation actually finished?

I do have an issue using Rancher that i can not wrap my head around: It is my first time using Rancher, so i installed it using Kube-Hetzner to create and manage my Kubernetes cluster using Terraform. To get warm with Rancher, i started by adding a test GitHub repository to see how i can deploy my projects as so: 1. I generated a new key and configured it as a deploy key in the repository. 2. I also tested the key locally using git pull. 3. Next, i added said key to the secrets of my local cluster. 4. After that i added my private GitHub repository to "Continous Delivery" on my local namespace and selected my SSH key for authentication. The issue i do have now is that i always do have the following error message:

Git git@github.com:username/repository.git refs/heads/master error: exit status 128, detail: ssh: connect to host github.com port 22: Connection timed out fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.

Configuring a deploy key is something i have done a hundret times now but with Rancher it just does not want to work. Did i do something wrong or can you recommend a step by step guide on how i can add a GitHub repository to CD using SSH key authentication?

From the error message you're receiving, it seems that the problem may not be with your deploy key setup, but rather that the system is unable to establish an ssh connection to github.

Have you test the ssh connectivity to github: ssh -T git@github.com

Is there a way to find out what IP addresses were assigned to masters/slaves in a cluster? I had a misconfigured dhcpd and after my rack restarted, the IPs have changed. I could restore the old ones, but I can't find out what they are as Rancher UI won't let me even access cluster config ("Cluster agent is not connected")

set the channel topic: For Rancher Desktop use #rancher-desktop

#general #rancher-setup For monitoring purpose , I need to get the % of PODS used and % of CPU used , as shown in the GUI, using the API , but not able to get the exact details using API , can anyone help me in this please?

👋 Hi everyone!

Is anyone aware of how to configure Resources WSL Integration in Rancher desktop

"Configure which WSL 2 distros you want to access Docker from."

The settings are available in Docker Desktop

Hi All, how can we force the removal of a dead node using rancher latest and rke2 setup. We have a brand new test install, to test failure we stopped a node, reinstalled it and then tried to delete it from rancher. Its seems stuck in deleting mode from rancher cluster manager. We then reinstalled that 'dead' node and tried reinserting that into the cluster but gave the machine a new name but now that is stuck in a pending state. Logs on the new machine say curl: (28) Operation timed out after 60001 milliseconds with 0 bytes received [ERROR] 000 received while downloading Rancher connection information. Sleeping for 5 seconds and trying again

in rancher logs I see errors like rancher-rancher-1 | 2023/06/26 110014 [ERROR] error syncing 'fleet-default/custom-ad9e4c268b51': handler unmanaged-machine: Get "https://10.43.201.200/k8s/clusters/c-m-hvp5kqxl/api/v1/nodes/sih001": dial tcp 10.43.201.200443 i/o timeout, requeuing where sih001 is the old machine name

Hey everyone, Can someone please let me know if I can install musl nd musl-dev pkg using zypper ?

Greetings, I'm desperate to find a way of converting so-called "Legacy Apps" to normal Apps, since upgrading Rancher from 2.5.x to 2.7.x, recently. This is a huge breaking change & breaks a lot in our workflow.

Hi All

Any one please guide me how to launch GUI centos using the Rancher desktop

Hi all, I have a question regarding Additional Trusted CAs: I’m aware of the docs, in fact that works fine -- but it seems to only affect the

rancher

Deployment, not the `cattle-cluster-agent`s of imported clusters. Thus when I add a

ClusterRepo

referencing a chart registry with a self-signed cert, doing so in the imported cluster won’t work due to the TLS cert error. Is that a bug or intentional? How would I add an additional trusted CA so it’s used within

cattle-cluster-agent

?

(For the record: I can get it to work by manually mounting the

tls-ca-additional

and running

update-ca-certificates

— the chart repo then works. But how can I configure Ranchen / the

cattle-cluster-agent

to do so without my manual intervention?)

any idea how to setup a Kubernetes cluster in Rancher using a network without DHCP (so I need to set a static IP for each node)?

which logging is best for Ramcher 2.6,
