I though Rancher App Marketplace was my solution but reading that questions.yaml doesnt support array type or dictionaries (which are 2 important datatypes in yaml), is total bumer

@agreeable-oil-87482 do you know if there is a plan to support array as a type in questions.yaml?

no way to implement that for instance via questions.yaml

hello, been trying to install rancher desktop on w10 as a more convenient docker+wsl setup. was successful with 1 pc (rancher 1.5.0) although i remember docker not starting correctly at the first attempts (not sure what helped) tried installing now (ranhcer 1.5.1) on my work pc docker does not start.

error during connect: Get "<http://localhost:2375/v1.24/containers/json>": dial tcp [::1]:2375: connectex: No connection could be made because the target machine actively refused it.

looking at logs and diffing between two machines i see this:

Hello good morning, in my company we use Rancher to deploy our applications, is it possible to obtain a report with the history of deployments made by each user with their date? Thank you very much in advance.

Hi, I just read about monitoring v2 implemnted for rancher2 above 2.6. My goal is to have separate observability cluster that will collect metrics from all our k8s clusters. Is it possible to use existing monitoring solution from rancher to get this goal? I see there is some extra pushprox application. Is it capable to collect from it a metrics from different clusters (on separate networks) and deliver to this observability cluster? Or should I do some sort of prometheus setup in federation mode to have some primary-secondary model?

Hi All, In a 9 node cluster, one master (etcd+controlplane) and 8 worker nodes. No need of any load balancer I believe. But what if I have 3 master nodes and 6 worker nodes. Does rancher manages load balancing on it's own? Or specifically we need to deploy load balancing for this? I've deployed rancher using docker in a VM and from rancher UI I've provisioned Kubernetes cluster

Hey guys! anyone had issues with rancher just deletes managed custom cluster on attempt to modify cluster configuration? I’ve submitted bug here https://github.com/rancher/rancher/issues/38833 this is very scary… my clusters are just destroyed when I modify cluster configuration…

Hey, I launched a single node cluster inside a VPN, I have an external IP address that points to the VM (which hosts the RKE cluster). How can I add another IP address for the x509 certificate so I can access the cluster from outside the VPN?

Did you refresh helm (helm repo update) or maybe your helm repository isn't called rancher-latest (helm repo list)

Hi Everyone, I'm new to kubernetes and RKE2. I just setup a 3 node cluster using vagrant and installed one server and two agents and I see that a couple of my ingress Pods are stuck in 'ContainerCreating' and a couple Canal Pods stopped with 'CrashLoopBackOff'. Is this expected/normal?

Hi, am able to use ingress-nginx to access rancher URL via NLB created by ingress. Now I want to use Istio instead of ingress-nginx in EKS to access rancher url. I removed ingress-nginx, and installed istio-ingress, but its giving SSL errors. Any implementation guide pls, for istio based rancher setup only.

Hi everyone, I need help with few issues. 1. I tried to create a postgresql container as a deployment workload in Rancher Desktop following this article https://www.hanaburtin.net/archives/83 without the NFS replication. Then created databases and users related to an application, and the application was running fine. But when I restart Rancher, the entire postgresql is truncated as a new one. The created databases and users are lost. 2. While restarting Rancher, is there any way to create an order in which the containers should start running? For deploying a micro-services application, the services must be started in certain order. The database container must be in ready state for the other services to start. So is there any way to ensure that. 3. When restarting Rancher, the IP Address of existing containers is getting changed sometimes. Is there any way to fix that? We've checked that Cluster IP doesn't change after restarting, but not sure if that's the correct way of referring containers. If anyone has faced and solved these issues, please share the references to follow.

Hello. I'm trying to deploy a cluster in a vSphere environment, without success. I've tried using RKE1, RKE2, even k3s but nothing works. I'll describe one of my attempts, using RKE2. I'm using a Ubuntu 20.04 template, including vmtoolsd. The virtual machine is created in vsphere, boots and get an IP address correctly. Then the installation script is executed (/usr/local/custom_script/install.sh) and is looping on the

retrieve_connection_info

function. The call to

/v3/connect/agent

is failing with a 401 Unauthorized error. The rancher server is accessible from the virtual machine. The script is called without any parameters but includes some references to my rancher instance :

CATTLE_AGENT_BINARY_BASE_URL

CATTLE_SERVER

CATTLE_TOKEN

. I don't understand why this is failing. Any idea?

Does rancher backup now support Azure Blob Storage seeing that Minio S3 -> Azure Blob Storage gateway is now deprecated

Hello all, Does anyone work with Rancher + Prometheus alerts + (possibly Slack or PagerDuty)? I need to configure 1) timing of scraping and 2) timing of sending alerts to slack when it is fired We have rancher 2.6.7 and Prometheus (from Apps charts) I have configured to send slack alerts, and I am getting alerts, but cannot find interval for scraping. Like, its sending fire alerts whenever it thinks it should be sending… 😏 I have under Monitoring > Advanced > PrometheusRules > resource kubernetes-apps and inside Group Name: kubernetes-apps (runbook from Github repo). Now I have changed timing of it in PromQL as well as duration which is given in seconds (above PromQL). I just dont know whether it is the location to configure scraping and sending alerts or does it have to be set through PodMonitoring in Monitoring (though podmonitoring should be just for pods) Please help…

You want to create the Persistent Volume that uses hostpath first with a similar manifest

kind: PersistentVolume
apiVersion: v1
metadata:
  name: hostpath-pv
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  reclaimPolicy:
    - Recycle
  hostPath:
    path: "/data"
