Allows to identify chart changes before actually running lint or install commands. This can be useful in the following cases: * In a CI setup where kind clusters are spun up on the fly, this makes it possible to decide whether a cluster is necessary at all. A PR may only contain changes that are not relevant to any charts. * By knowing upfront which charts have changed, it is possible to load a per-chart CI configuration which would allows us to determine the number of nodes needed in a kind cluster. For most charts, one node is enough, but in certain scenarios, especially for StatefulSets, we may want to test with pod anti-affinity where replicas have to be spread across multiple nodes.

ct lint
Lint and validate a chart
Synopsis
Run 'helm lint', version checking, YAML schema validation on 'Chart.yaml', YAML linting on 'Chart.yaml' and 'values.yaml', and maintainer validation on
- changed charts (default)
- specific charts (--charts)
- all charts (--all)
in given chart directories.
Charts may have multiple custom values files matching the glob pattern '*-values.yaml' in a directory named 'ci' in the root of the chart's directory. The chart is linted for each of these files. If no custom values file is present, the chart is linted with defaults.
ct lint [flags]
Options
--all Process all charts except those explicitly excluded.
Disables changed charts detection and version increment checking
--chart-dirs strings Directories containing Helm charts. May be specified multiple times
or separate values with commas (default [charts])
--chart-repos strings Additional chart repositories for dependency resolutions.
Repositories should be formatted as 'name=url' (ex: local=http://127.0.0.1:8879/charts).
May be specified multiple times or separate values with commas
--chart-yaml-schema string The schema for chart.yml validation. If not specified, 'chart_schema.yaml'
is searched in the current directory, '$HOME/.ct', and '/etc/ct', in
that order.
--charts strings Specific charts to test. Disables changed charts detection and
version increment checking. May be specified multiple times
or separate values with commas
--check-version-increment Activates a check for chart version increments (default: true) (default true)
--config string Config file
--debug Print CLI calls of external tools to stdout (Note: depending on helm-extra-args
passed, this may reveal sensitive data)
--excluded-charts strings Charts that should be skipped. May be specified multiple times
or separate values with commas
--helm-repo-extra-args strings Additional arguments for the 'helm repo add' command to be
specified on a per-repo basis with an equals sign as delimiter
(e.g. 'myrepo=--username test --password secret'). May be specified
multiple times or separate values with commas
-h, --help help for lint
--lint-conf string The config file for YAML linting. If not specified, 'lintconf.yaml'
is searched in the current directory, '$HOME/.ct', and '/etc/ct', in
that order
--remote string The name of the Git remote used to identify changed charts (default "origin")
--target-branch string The name of the target branch used to identify changed charts (default "master")
--validate-chart-schema Enable schema validation of 'Chart.yaml' using Yamale (default: true) (default true)
--validate-maintainers Enable validation of maintainer account names in chart.yml (default: true).
Works for GitHub, GitLab, and Bitbucket (default true)
--validate-yaml Enable linting of 'Chart.yaml' and values files (default: true) (default true)
