I am completely new to Rancher, and trying to setup my first rancher server for evaluation. I elected to use the docker installation as it appeared to be the simplest for my purposes. However, I cannot get it to work. I created a new Ubuntu server, with the latest iso file. I installed Docker using the instructions from the Docker website. All seemed goo to this point. I then used the following command to start the Rancher docker image. docker run -d --restart=unless-stopped -p 80:80 -p 443:443 --privileged -v /opt/rancher:/var/lib/rancher rancher/rancher:latest docker ps indicates the container is running, however on checking the container logs, all is not right. I am getting the error, and cannot seem to find the cause. Can anyone shed any light on what I may be doing wrong.

anyone been thorough the same situation? any leads are highly appreciated!

Hey there, we had a serious incident the other day with one of our rancher server managed rke cluster , all our apiservers were burning all the hosts ram, >70GB. We spun up an extra apiserver on a very big machine, it then ate 450GB for few dozen of minutes before reducing to ~7GB. Have you seen such behavior previously ? We're running rancher 2.6.5 and 1.20.15. thanks

Hello, Anyone knows if it is possible to scrape an external target? I've installed Monitoring in K3s/rancher 2.6.4. I have a nvidia_gpu exporter target that is external to the cluster that I would like to scrape scrapping. Does any know if this is possible, or could point me in the right direction?

i am following this doc to deploy rancher on gke but I cannot get to the rancher url. https://rancher.com/docs/rancher/v2.5/en/installation/install-rancher-on-k8s/gke/

but I cannot get to the url and says 404 error

any idea?

Using rancher desktop 1.5.1 i'm having an issue with changing the cpu/ram allocation for the VM running the node. Upon increasing the CPU and Ram allocation limits the VM will get more CPU resources but not RAM for some reason that stays at the default value.

Hello, I've been having this problem for some time, looked and a lot of places up to no avail, and a friend told me that he had help with it here on the Rancher slack. The error is: docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": unexpected EOF. See 'docker run --help'. I got this error on every docker run or docker pull command 😕 Someone knows how to solve this please 🙂

Hi, have rancher ver 2.6.6 running on AWS EKS cluster (http port,not with tls) as service. I created another EKS cluster with terraform and trying to import via Rancher Console. Getting this error "Error while applying agent YAML, it will be retried automatically: exit status 1, Unable to connect to the server: remote error: tls: internal error" on stage "Provisioning". Any suggestions pls. I also executed "kubectl create clusterrolebinding cluster-admin-binding \ --clusterrole cluster-admin \ --user <iamuser> . But same issue

Docker starts rancher, and an error occurs when creating a new cluster: Waiting for etcd, controlplane and worker nodes to be registered
