This feature provides an alternative to downloading a kubeconfig and installing kubectl locally. It opens a fully configured shell within a browser tab, equipped with kubectl and an associated kubeconfig. This convenient setup allows you to quickly access your Kubernetes clusters directly from the DuploCloud Portal, with no need for downloading or configuring files on your machine.

Enabling kubectl shell in the DuploCloud Platform

For EKS, kubectl is already enabled in the DuploCloud Platform. Once the EKS infrastructure is ready, you can navigate to Kubernetes -> Services in the DuploCloud platform and use the KubeCtl menu options to view the kubectl token, settings, and configuration details.

To set up the kubectl shell in DuploCloud for GKE and AKS users, see the links below.

• kubectl Shell for GKE

• kubectl Shell for AKS
