A good approach would be from the CLI in my opinion. You can do something like this: rancher kubectl get nodes -o jsonpath='{range .items[*]}{.metadata.name}{"\n"}{end}'. After you identify which node you want to add the env variable. rancher kubectl patch node name_of_node -p '{"spec":{"config":{"kubeletConfig":{"environment":{"HTTP_PROXY":"http://your-proxy:PORT"}}}}}'

without http proxy, Kubernetes is not installed in Harvester VMs because the VM is trying to access ntp endpoints..

And you want to set this variable for all provisioned machines in rancher's harvester?.

yes, you’re right

Well in that case you can access the rancher ui and log in to the harvester cluster. Then navigate to the "Clusters" tab and select the cluster for which you want to set the HTTP_PROXY variables -> Click on the cluster name to enter the cluster details page. -> In the left sidebar, click on "Nodes" to view the list of nodes in the cluster. -> Select the nodes for which you want to set the HTTP_PROXY variable. -> Once you have selected the nodes, click on the "More" button at the top of the nodes list and choose "Edit".

I’m not able to find the “Nodes” tab on Rancher v2.7.4

In the "Edit Nodes" dialog box, locate the "Environment Variables" section. -> Click on the "Add" button to add a new environment variable. -> In the "Name" field, enter "HTTP_PROXY". -> In the "Value" field, enter the URL of your HTTP proxy server. -> Click "Save" to apply the changes.

I’m deploying the cluster on Harvester

Umm, you are right I think there were changes on 2.7.4 let me check that.

I’ve tried to put the Environment Variables here but it doesn’t seem to work.

That's for the agents

where is the projects tab?

Within that project, click on Add and choose Deployment.

yes, because the network where was deployed does not have internet access, that’s why I’m trying to setup an HTTP_PROXY

Gotcha, then you to the Project tab. Did you see it?.

no, in the above screenshot there is no Project tab unfortunetly

Make sure to provide the necessary details for the deployment, container image, ports, etc.

please give me a screenshot, it seems that we’re talking about different things

Is right where you at just click on the cluster name I guess.

if you still have any ideas, please let me know, thank you
