Work with Google Cloud and Kubernetes YAML in Cloud Code for Cloud Shell

Stay organized with collections Save and categorize content based on your preferences.

Cloud Code for Cloud Shell is designed to make Kubernetes and Cloud Build configuration easier by linting schema for both structure and valid values and providing descriptive errors. Cloud Code comes with out-of-the-box solutions for common schema, smart completions, and documentation on hover.

Supported YAML configuration files

Cloud Code also supports popular Kubernetes custom resource definitions (CRDs), like Kubeflow, out-of-the-box.

Using custom schema

With Cloud Code, you can provide your own CRD schema with the cloudcode.yaml.crdSchemaLocations setting in your settings.json file. You can point to either a local file or a URL. URLs pointing to github.com are automatically converted to raw.githubusercontent.com.

Pulling schema from a cluster

When you switch to a cluster running Kubernetes v1.16 and later in the Kubernetes view, Cloud Code automatically pulls the schema of all installed CRDs.

Configuring with snippets

Out-of-the-box snippets for common YAML schema (using Command/Ctrl+Space to view options) make it easy to start a new YAML file or add to an existing one without errors, while still following best practices. Cloud Code makes it easier to work with repetitive fields by filling out the remaining instances after you fill in the first field.

Cloud Code offers the following snippets:

  • Anthos Config Management - Cluster
  • Anthos Config Management - Cluster Selector
  • Anthos Config Management - Config Management
  • Anthos Config Management - Namespace Selector
  • Cloud Build - Cloud Run deployment
  • Cloud Build - Docker container build
  • Cloud Build - GKE deployment
  • Cloud Build - GKE Skaffold deployment
  • Cloud Build - Go build
  • Cloud Build - Terraform plan + apply
  • Config Connector - BigQueryDataset
  • Config Connector - BigQueryTable
  • Config Connector - BigtableCluster
  • Config Connector - BigtableInstance
  • Config Connector - PubSubSubscription
  • Config Connector - PubSubTopic
  • Config Connector - RedisInstance
  • Config Connector - SpannerInstance
  • Kubernetes - ConfigMap
  • Kubernetes - Deployment
  • Kubernetes - Ingress
  • Kubernetes - Pod
  • Kubernetes - Secret
  • Kubernetes - Service
  • Migrate for Anthos - Export
  • Migrate for Anthos - PersistentVolumeClaim
  • Migrate for Anthos - StatefulSet
  • Skaffold - Bazel
  • Skaffold - Getting-started
  • Skaffold - Helm deployment
  • Skaffold - Kaniko

Completing with context

Based on the current schema, Cloud Code provides contextual completions and relevant docs to help you choose the right option.

Validating YAML schema

Cloud Code offers schema validation support by flagging invalid tags and values in your YAML files and suggesting fixes when possible.

Value of name field red-underlined to highlight an invalid value of '1234'; hover text states: "Incorrect type. Expected string."

Discovering documentation on hover

Cloud Code surfaces relevant documentation when you hold the pointer over a value in the schema.

Accessing resource definitions

To view definitions for a resource, right-click the resource and then choose Go to Definition or Peek Definition.

Applying a YAML file

To apply a configuration change using the current file, open the command palette (press Ctrl/Cmd+Shift+P or click View > Command Palette) and then run Cloud Code: Apply Current JSON/YAML File to K8s Deployed Resource.

This command brings up a diff view for you to review changes. Click Apply when prompted whether to apply this change. This runs kubectl apply -f.

Viewing differences between YAML files

To view the differences between a YAML file in source control and a deployed YAML file, open the command palette (press Ctrl/Cmd+Shift+P or click View > Command Palette) and then run Cloud Code: Diff Current JSON/YAML File with K8s Deployed Resource.

Performing a dry-run of a YAML file

To perform a dry run of your configuration and check its validity, open the command palette (press Ctrl/Cmd+Shift+P or click View > Command Palette) and run Cloud Code: Dry-run current config for server-side validation and Cloud Code: Dry-run Current Config for Client-side Validation.

This runs kubectl apply -f dry-run=server (or kubectl apply -f dry-run=client, for the Client option) and displays successful validation (or an error message, if your config file isn't valid) as a toast notification.

In the following example, server-side dry-run validation of the configuration file, hello.deployment.yaml, returns an error when trying to create a deployment because the specified namespace, random-namespace, doesn't exist.

Server-side dry-run validation fails on `hello.deployment.yaml` with an error message displayed as a toast. The details of the error are found in the Output channel; the namespace 'random-namespace' doesn't exist

Working with secrets

Using configuration maps and secrets is a key part of working with Kubernetes. To view the context of a base64 secret with Cloud Code, hold the pointer over the secret to decode it.
