Garden 0.12.7 is out!

Along with a few bug fixes and performance improvements, this release includes a major new Garden feature: Templated modules.

Templated Modules

You can now create customized templates for modules or sets of modules, and render them using templated modules.

These templates allow you to define your own schemas and abstractions that are translated at runtime to one or more modules.

Module templates can include any supporting files (such as Kubernetes manifests, common configuration files, Dockerfiles etc.).

For example, you could set up a module template that generates a container module and an accompanying kubernetes module, where the image built by the container module is used by the kubernetes module:

kind: ModuleTemplate
name: k8s-container
inputsSchemaPath: module-templates.json
modules:
  - type: container
    name: ${parent.name}-image
    description: ${parent.name} image
  - type: kubernetes
    name: ${parent.name}-manifests
    build:
      dependencies: ["${parent.name}-image"]
    files: [.manifests.yml]
    generateFiles:
      - sourcePath: manifests.yml
        targetPath: .manifests.yml

This template would then be used as follows:

kind: Module
type: templated
template: k8s-container
name: my-service
inputs:
  containerPort: 8080
  servicePort: 80

See the templated-k8s-container example project for more context on the snippets above.

Module templates can be reused across your project (or projects), which may greatly reduce the amount of configuration needed to add a module or a set of modules to your project.

When used well, module templates can:

• Greatly reduce repetition in your configuration.
• Help keep your configuration consistent across modules.
• Simplify maintenance.

See our Module Templates guide for details.

Faster Remote Source Resolution

We now resolve remote sources in parallel, which speeds up the initialization of projects with several remote sources.
