Working with Google Cloud Platform and Kubernetes YAML

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

Supported YAML configuration files

Additionally, Cloud Code also supports popular Kubernetes CRDs, like Kubeflow, out-of-the-box.

Using custom schema

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

Pulling schema from a cluster

When you switch to a cluster running Kubernetes v1.16 and above in the Kubernetes explorer, 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. Additionally, it's easier to work with repetitive fields; fill in one and Cloud Code fills out the remaining instances.

Currently, the following snippets are offered:

  • 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 - Go build
  • Cloud Build - Terraform plan + apply
  • Config Connector - BigQueryDataset
  • Config Connector - BigQueryTable
  • Config Connector - BigtableCluster
  • Config Connector - BigtableInstance
  • Config Connector - PubSubSubscription

  • Migrate for Anthos - StatefulSet
  • Skaffold - Bazel
  • Skaffold - Getting-started

Completing with context

Based on the current schema, Cloud Code will provide 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 hover over a value in the schema.

Accessing resource definitions

Quickly view definitions for resources by right-clicking and choosing 'Go to Definition' or 'Peek Definition'.

If you'd like to view the differences between a YAML file in source control and a deployed YAML file, you can use Cloud Code: Diff the current JSON/YAML file with Kubernetes deployed resource from the Command Palette (accessible with Cmd/Ctrl+ Shift+P). This will bring up a diff view for you to compare and contrast two schema files.

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, simply hover over it to decode it.
