![]() ![]() To get more details such IP address of the pod,worker node on which the respective pod is running etc, we will combine the above command with -o wide: ~]# kubectl get pods -o wide List the available pods: ~]# kubectl get pods Use kubectl create command to create the pod using the provided YAML file. Here I will create a simple pod with nginx server running on port 80: Once your work is done, you can go ahead and kill the PID of the background process to close the tunnel. This will print the PID of the process and then send the command to background and you will be able to use the terminal. Kubectl port-forward pods/my-pod 8080:80 & If we cancel or quit the kubectl command, typically by pressing Ctrl + C, then port forwarding will immediately end. Note that you will not have a Command Prompt back after executing these commands, which is because the command is actively running to keep this particular tunnel we've requested alive. Sample command to perform port forwarding on service: kubectl port-forward service/my-service 8080:80 Sample command to perform port forwarding on replicaset: kubectl port-forward replicaset/my-replicaset 8080:80 Sample command to perform port forwarding on deployment: kubectl port-forward deployment/my-deployment 8080:80 Sample command to perform port forwarding on pod: kubectl port-forward pods/my-pod 8080:80 The general syntax to forward ports using kubectl would be as shown below but we will explore all possible options: kubectl port-forward : This command is very useful mostly when you would want to troubleshoot a misbehaving pod. We use this command to access container content by forwarding one (or more) local ports to a pod. That means the system running it needs access to the API server, and any traffic will get tunneled over a single HTTP connection. kubectl port-forward makes a specific Kubernetes API request. This can be performed using kubectl port-forward command. Refer to the command's help for more details.We can use kubectl to set up a proxy that will forward all traffic from a local port we specify to a port associated with the Pod we determine. Provides a lightweight SSH client with the ssh command, that uses portįorwarding. To connect to a VirtualMachineInstance from your local machine, virtctl The VirtualMachineInstance either from the CLI or a web-UI. One use-case for this subresource is to forward SSH traffic into Instance by using the virtualmachineinstances/portforward subresource of the The user can create a websocket backed network tunnel to a port inside the # Create a VM referencing the Secret using propagation method configDrive kubectl create -f - <<EOF apiVersion: kubevirt.io/v1 kind: VirtualMachine metadata: name: testvm spec: running: true template: spec: domain: devices: disks: - disk: bus: virtio name: containerdisk - disk: bus: virtio name: cloudinitdisk rng: # Disable SELinux for now, so qemu-guest-agent can write the authorized_keys file # The selinux-policy is too restrictive currently, see open bugs: # - # - # - bootcmd: - setenforce 0 name: cloudinitdisk EOF Accessing the VMI using virtctl ¶ This allows keeping theĪpplication data in the cloud-init user data separate from the credentialsĪ Kubernetes Secret can be created from an SSH public key like this: Placing the SSH public key into a Kubernetes Secret. Public keys at startup time independently of the cloud-init user data by The virtual machine's access credential API allows statically injecting SSH However, there are more flexible options available. One option for injecting public SSH keys into a VM is via Machines, allowing multiple customization operations. Users creating virtual machines can provide startup scripts to their virtual Static SSH public key injection via cloud-init ¶ Once a SSH public key is injected into the virtual machine, it can beĪccessed via virtctl. Which allows keys to be dynamically updated both at boot and during runtime. Which places keys on the virtual machine the first time it is booted. In general, these methods fall into two categories: KubeVirt provides multiple ways to inject SSH public keys into a virtual Of gaining secure and passwordless access to a virtual machine. ![]() (like Ansible) to provision the virtual machine. SSH public keys into the virtual machines at boot. Port with SSH to your machine (either direct or in combinationĪ common operational pattern used when managing virtual machines is to inject ![]() As an alternative you can proxy the API server Note: If you are using virtctl via SSH on a remote machine, you need toįorward the X session to your machine.
