Kubernetes backend for Pants

This backends implements targets for working with Kubernetes clusters using raw YAML.

• kubectl for cluster operations

Targets

There's currently three targets for pants-backend-k8s:

• k8s_source
• k8s_object
• k8s_objects

k8s_source

A file that can be passed into other k8s fields that are not source fields. For example, k8s_object.template.

k8s_source(
    name="namespace.yaml",
    source="namespace.yaml",
)

Argument	Meaning	Default value
name	The target name	Same as any other target, which is the directory name
source	The raw file	Required
decsription	A description of the target	""
tags	List of tags	[]

This'll eventually be automated like other rules once a suitable heuristic for generation with tailor is found. PRs welcome!

k8s_object

Input for a kubernetes command, either generated via kustomize or via k8s_source.

k8s_object(
    name="k8s",
    description="the chat backend"
    template=[":kustomize"],
    namespace="chat-app",
    cluster="prod",
)

Argument	Meaning	Default value
name	The target name	Same as any other target, which is the directory name
template	The target to act on	Required
namespace	Namespace to target	Optional, will use default kubectl namespace
cluster	cluster to target	Optional, will use default kubectl cluster
decsription	A description of the target	""
tags	List of tags	[]

k8s_object is a generator for kubernetes target parametrized by the potential commands that are available: apply, create, get, describe, replace, and delete.

k8s_objects

A collection of kubernetes objects that should be managed together.

k8s_objects(
    name="my-service",
    description="all components of service-x"
    objects=[":namespace", ":deployment"],
)

Argument	Meaning	Default value
name	The target name	Same as any other target, which is the directory name
objects	k8s_object targets that should be managed	Required
decsription	A description of the target	""
tags	List of tags	[]

Like k8s_object, k8s_objects is a generator for parametrized targets for the commands that are available: apply, create, get, describe, replace, and delete.
