Cloud Code for VS Code Kubernetes overview

This page provides an overview of Kubernetes development in Cloud Code.

The Kubernetes section lets you access information about your clusters, nodes, workloads, and more, right from your IDE. You can also set a current context, stream and view logs, open an interactive terminal, and look up resource descriptions with the Kubernetes section.

Cloud Code uses the default kubeconfig file, located under the $HOME/.kube directory on MacOS/Linux or %USERPROFILE%\.kube on Windows, for retrieving Kubernetes resources. You can switch or add new Kubeconfig files from within the Kubernetes section. Kubeconfig files are YAML files containing your Kubernetes cluster details, certificate, and secret token for authenticating to the cluster.

To use a kubeconfig file other than the default kubeconfig, refer to the Work with kubeconfig files guide.

To view and manage your Kubernetes resources, access the

section by clicking

and expanding the

section. To view debugging sessions or create a sample app, expand the

section.

When attempting to debug, you may be prompted to authenticate your credentials to run and debug an application locally.

Use the Development sessions to run or debug your Kubernetes application or create a sample application using a template.

When you start a development or debugging session, the Development sessions section displays the structured logging view.

To access the Development sessions, click

and expand the

section.

The Kubernetes section is powered by kubectl. As long as you've configured your kubectl config file to access your clusters, you can use the Kubernetes section to add clusters, browse all your available namespaces, resources, and nodes for your clusters, regardless of them being in the active or inactive context.

The available general Kubernetes actions, accessible through their icons in the Kubernetes section, are:

• add KubeConfig
• refresh Refresh the Kubernetes section
• question_mark Open the Cloud Code Kubernetes documentation in a web browser

The available Kubernetes actions, accessible through their icons in the Kubernetes Development sessions section, are:

You can copy any Kubernetes resource name to the clipboard (including container and cluster names). To copy a resource name, right-click on the resource and choose Copy resource name.

The Kubernetes section watches for changes and automatically refreshes to reflect updates. To force a refresh of any Kubernetes resource to fetch its latest information, right-click the resource and choose Refresh.

You can also force a refresh of the entire

section using the

section's refresh button.

To display the details of any non-cluster resource, right-click the resource, then select

. A terminal opens and displays the resource information.

To configure how your application is run, you can customize your skaffold.yaml file.

You can also configure your launch by specifying the following fields in the

configuration in your

file:

• skaffoldConfig: Specify the Skaffold configuration file that contains the build and deploy settings.
• profile: Specify your preferred Skaffold profile. If not defined, the default profile is used.
• imageRegistry: Specify the image registry to push images to.
• watch: Specify whether to watch for changes in the workspace and rerun the application. Unless explicitly set to false, true by default.
• cleanUp: Specify whether to delete deployed Kubernetes resources in the cluster after the application is terminated. Unless explicitly set to false, true by default.
• portForward: Specify whether to forward ports for exposed Kubernetes resources on your cluster to your local machine. Unless explicitly set to false, true by default.

To view the YAML of a resource in your cluster, select or hover over the resource to show the

and

icons. Select the

button to open the YAML file corresponding to your specified resource in a new editor tab.

You can stream and view logs from Kubernetes resources into the Kubernetes section console to monitor their progress.

To open the

, open the command palette by pressing

or clicking

then select

.

The logs viewer opens in a new editor tab.

To view logs for a pod or container, right click on the resource and select View logs.

For pods and containers, you can open an interactive terminal by right-clicking the pod or container and selecting Get terminal.

The Kubernetes section displays clusters, namespaces, nodes, workloads (such as deployments, replicasets, pods and containers), services and ingresses, configurations (such as secrets and config maps) and storage (such as volumes). Using the Kubernetes section, you can perform unique actions on some of these resources.

• Add a cluster to the Kubeconfig: Add an existing GKE or minikube cluster or create a new one.

The Add Cluster dialog appears and you can choose the project and cluster you'd like to use or create a new cluster.

• Set as active cluster: Set the specified cluster as active such that your configured kubectl context accesses this cluster by default.

The Kubernetes section refreshes automatically and you'll see the Kubernetes symbol next to the appropriate cluster.

If a cluster has multiple contexts configured, you'll be able to choose one of the available contexts to set as the current context.

• Set as active namespace: Set a namespace as active such that your configured kubectl context accesses this namespace by default.

  Right-click the namespace you want to set as active.

If this action is successful, the Kubernetes section refreshes automatically and you'll see an asterisk next to the namespace to signify that it's part of the current context.

Note that a Kubernetes context is a shortcut which gives you quick access to a namespace in your cluster. Contexts are normally created automatically when you start a minikube or GKE cluster. If you don't see the Set as current context option for a given namespace and you'd like to create a context for it, use the kubectl config set-context command in your terminal to set a context with your preferred cluster, user, and namespace.

• View Logs: View logs from a pod into the Kubernetes section Console.

• Get Terminal: Get terminal for a pod in the Kubernetes section Console.

  Additionally, running pods have colored status marks next to their labels:

  • Red: Pod is in a failed state
  • Yellow: Pod is starting or terminating
  • Green: Pod is healthy and running

• View logs: View logs from a container into the Kubernetes section console.
• Get Terminal: Get terminal for a container in the Kubernetes section console.

• View logs: View logs from a deployment into the Kubernetes section console.

  Live deployments have colored status marks next to their labels and counts of current/total replicas:

  • Yellow: Deployment does not have minimum availability or have image problems.
  • Green: Deployment is healthy and had minimum availability.

Nodes of your cluster have colored status marks next to their names:

• Yellow: Node has a resource problem such as memory or disk availability.
• Green: Node is healthy.

The Kubernetes section lists all Custom Resource Definitions (CRDs) installed and available on your cluster:

• Get started with Cloud Code for VS Code for Kubernetes by creating and deploying a Kubernetes application from a code sample.
• Use file sync and hot reloading to speed up development.
• Debug your application in Cloud Code
