Backport of https://github.com/helm/helm/pull/6010 to dev-v3 (the
description below is a copy-paste from the original v2 branch PR).
As https://github.com/helm/helm/pull/6016 is now merged to dev-v3, the
change is reasonably trivial.
This change is an attempt to address the common problem of json number
unmarshalling where any number is converted into a float64 and
represented in a scientific notation on a marshall call. This behavior
breaks things like: chart versions and image tags if not converted to
yaml strings explicitly.
An example of this behavior: k8s failure to fetch an image tagged with a
big number like: $IMAGE:20190612073634 after a few steps of yaml
re-rendering turns into: $IMAGE:2.0190612073634e+13.
Example issue: #1707
This commit forces yaml parser to use JSON modifiers and explicitly
enables interface{} unmarshalling instead of float64. The change
introduced might be breaking so should be processed with an extra care.
Due to the fact helm mostly dals with human-produced data (charts), we
have a decent level of confidence this change looses no functionality
helm users rely upon (the scientific notation).

* Add the Schema type and a function to read it
* Added a function to read a schema from a file
* Check that values.yaml matches schema
This commit uses the gojsonschema package to validate a values.yaml file
against a corresponding values.schema.yaml file.
* Add functionality to generate a schema from a values.yaml
* Add Schema to Chart and loader
* Clean up implementation in chartutil
* Add tests for helm install with schema
* Add schema validation to helm lint
* Clean up "matchSchema"
* Modify error output
* Add documentation
* Fix a linter issue
* Fix a test that broke during a rebase
* Clean up documentation
* Specify JSONSchema spec
Since JSONSchema is still in a draft state as of this commit, we need to
specify a particular version of the JSONSchema spec
* Switch to using builtin functionality for file extensions
* Switch to using a third-party library for JSON conversion
* Use the constants from the gojsonschema package
* Updates to unit tests
* Minor change to avoid string cast
* Remove JSON Schema generation
* Change Schema type from map[string]interface{} to []byte
* Convert all Schema YAML to JSON
* Fix some tests that were broken by a rebase
* Fix up YAML/JSON conversions
* This checks subcharts for schema validation
The final coalesced values for a given chart will be validated against
that chart's schema, as well as any dependent subchart's schema
* Add unit tests for ValidateAgainstSchema
* Remove nonessential test files
* Remove a misleading unit test
The TestReadSchema unit test was simply testing the ReadValues function,
which is already being validated in the TestReadValues unit test
* Update documentation to reflect changes to subchart schemas
Prior to this, using the semver template functions with the full
version, which is represented in the GitVersion, was not possible
for helm template and lint commands because the property was not
populated by default. This update adds default handling.
Closes#3349
This commit adds --kube-version flag to helm template. It allows you to
override the Kubernetes version used as Capabilities.KubeVersion.Major/Minor (e.g. 1.7).
Added more tests to test following comibnations of subcharts and requirements.yaml
- [ ] subcharts not specified in requirements.yaml
- [ ] some subcharts specified in requirements.yaml while others should be picked directly from "charts\"
- [ ] all subcharts specified in requirements.yaml without alias
- [ ] subcharts specified in requirements.yaml with alias is already tested
This feature adds the ability to selectively control the loading of charts using entries in top chart's values.
When 'helm install --set tags.mytag=true', charts with that tag will be enabled unless disabled in parent by condition.
When 'helm install --set mychart.enabled=true', charts with that yaml path specified will be enabled.
Closes#1837
This causes 'helm dep [up|install]' to ignore files in charts/ that
start with either a dot or an underscore. It also changes the
chartloader to ignore those files.
Also, if a 'helm dep up' does not find a charts/ directory, it creates
one.
Closes#1342
Some fields were introduced to Chart metadata after Alpha.4, but are not
going to be used ever. So we made the decision to remove them before we
get stuck with ugliness.
This should not break compatibility, since these fields were not used.
This also refactors significant portions of the CLI, moving much of the
shared code into a library.
Also in this release, a testing repository server has been added.
This adds a few extra settings to the default .helmignore file. In
doing this, I found a bug that some directory patterns are not
evaluated correctly. Fixed that and added tests.
Closes#989Closes#1027
This provides support for "global" variables. It does this by
declaring "global" to be a special namespace. It then copies this
namespace into every subchart, coalescing it into any "global"
namespace found there.
The net result is that if "global.foo" is set in the YAML file, it
will be available to every chart/subchart as ".global.foo" regardless of
where that chart is in the subchart tree.
