helm_chart

A Helm chart.

Backend: pants.backend.experimental.helm

chart​

str | None
default: 'Chart.yaml'

The chart definition file.

dependencies​

Iterable[str] | None
default: None

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].

This augments any dependencies inferred by Pants, such as by analyzing your imports. Use pants dependencies or pants peek on this target to get the final result.

See https://www.pantsbuild.org/2.23/docs/using-pants/key-concepts/targets-and-build-files for more about how addresses are formed, including for generated targets. You can also run pants list :: to find all addresses in your project, or pants list dir to find all addresses defined in that directory.

If the target is in the same BUILD file, you can leave off the BUILD file path, e.g. :tgt instead of helloworld/subdir:tgt. For generated first-party addresses, use ./ for the file path, e.g. ./main.py:tgt; for all other generated targets, use :tgt#generated_name.

You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.

description​

str | None
default: None

A human-readable description of the target.

Use pants list --documented :: to see all targets with descriptions.

kubeconform_ignore_missing_schemas​

bool | None
default: None
backend: pants.backend.experimental.helm.check.kubeconform

Whether to fail if there are missing schemas for custom resources.

kubeconform_ignore_sources​

Iterable[str] | None
default: None
backend: pants.backend.experimental.helm.check.kubeconform

Regular expression patterns specifying paths to ignore.

kubeconform_kubernetes_version​

str | None
default: None
backend: pants.backend.experimental.helm.check.kubeconform

Kubernetes version to use for the validation.

kubeconform_reject_kinds​

Iterable[str] | None
default: None
backend: pants.backend.experimental.helm.check.kubeconform

List of kinds or GVKs to reject.

kubeconform_skip_kinds​

Iterable[str] | None
default: None
backend: pants.backend.experimental.helm.check.kubeconform

List of kinds or GVKs to ignore.

kubeconform_strict​

bool | None
default: None
backend: pants.backend.experimental.helm.check.kubeconform

Run Kubeconform in strict mode.

lint_quiet​

bool | None
default: None

If set to true, print only warnings and errors.

lint_strict​

bool | None
default: None

If set to true, enables strict linting of this Helm chart.

output_path​

str | None
default: '${spec_path_normalized}/${target_name_normalized}${file_suffix}'

Where the built directory tree should be located.

If undefined, this will use the path to the BUILD file, For example, src/charts/mychart:tgt_name would be src.charts.mychart/tgt_name/.

Regardless of whether you use the default or set this field, the path will end with Helms's file format of <chart_name>-<chart_version>.tgz, where chart_name and chart_version are the values extracted from the Chart.yaml file. So, using the default for this field, the target src/charts/mychart:tgt_name might have a final path like src.charts.mychart/tgt_name/mychart-0.1.0.tgz.

When running pants package, this path will be prefixed by --distdir (e.g. dist/).

Warning: setting this value risks naming collisions with other package targets you may have.

registries​

Iterable[str] | None
default: ('<ALL DEFAULT HELM REGISTRIES>',)

List of addresses or configured aliases to any OCI registries to use for the built chart.

The address is an oci:// prefixed domain name with optional port for your registry, and any registry aliases are prefixed with @ for addresses in the [helm].registries configuration section.

By default, all configured registries with default = true are used.

Example:

# pants.toml
[helm.registries.my-registry-alias]
address = "oci://myregistrydomain:port"
default = false # optional

# example/BUILD
helm_chart(
    registries = [
        "@my-registry-alias",
        "oci://myregistrydomain:port",
    ],
)

The above example shows two valid registry options: using an alias to a configured registry and the address to a registry verbatim in the BUILD file.

repository​

str | None
default: None

Repository to use in the Helm registry where this chart is going to be published.

If no value is given and [helm].default-registry-repository is undefined too, then the chart will be pushed to the root of the OCI registry.

skip_kubeconform​

bool
default: False
backend: pants.backend.experimental.helm.check.kubeconform

If set to true, do not run any kubeconform checking in this Helm target when running pants check.

skip_lint​

bool
default: False

If set to true, do not run any linting in this Helm chart when running pants lint.

skip_push​

bool
default: False

If set to true, do not push this Helm chart to registries when running pants publish.

sources​

Iterable[str] | None
default: ('.helmignore', 'README.md', 'LICENSE', 'values.yaml', 'values.yml', 'values.schema.json', 'templates/*.yaml', 'templates/*.yml', 'templates/*.tpl', 'templates/NOTES.txt', 'crds/*.yaml', 'crds/*.yml')

A list of files and globs that belong to this target.

Paths are relative to the BUILD file's directory. You can ignore files/globs by prefixing them with !.

Example: sources=['values.yaml', 'templates/*.yaml', '!values_ignore.yaml']

tags​

Iterable[str] | None
default: None

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run pants --tag='integration_test' test :: to only run on targets with that tag.

version​

str | None
default: None

Version number for the given Helm chart.

When specified, the version provided in the source Chart.yaml file will be overriden by the value given to this field.
