What happened:

$ ct lint-and-install   --chart-dirs .
Linting and installing charts...
Error loading configuration: 'chart_schema.yaml' neither specified nor found in default locations

What you expected to happen:

It should lint charts in the local directory. I have no idea how the chart_schema.yaml should look like.

How to reproduce it (as minimally and precisely as possible):

1. Create a dir.
2. Create a chart inside the dir.
3. Run ct lint --chart-dirs .

Thank you!

Update Same for lintconf.yaml. I believe the program should not require any specific configs to run it locally but just use some predefined settings.

@KIVagant I agree that we should define defaults for both of these that are shipped with the binary.

In the mean time, you could either use the docker image (which also comes with yamllint and yamale installed) or use ct with the example config files found here:

As a newbe to "chart-testing" i think you could use this one-liner:
docker run -it --rm --name ct --volume $(pwd):/data quay.io/helmpack/chart-testing:v2.3.0 sh -c "ct lint --all --debug --chart-dirs /data/"

(after you did docker pull quay.io/helmpack/chart-testing:v2.3.0)

My expectation is that "charts-testing" searches for charts within that folder and in all sub-folders and i expect that it lists all found charts in the results:

Linting charts...
Version increment checking disabled.

So i guess i miss something.

What command worked for you?

Actual question for me too. I want to check local charts In CI.
I tried to use ct binary like:

ct lint --charts charts/* --chart-dirs charts/ --chart-yaml-schema helm_default_chart_schema.yml --lint-conf helm_lint_config.yaml --debug

In result I need to have running local helm repo for it.

So, my general idea to check resources/requests for each places where possible (deployment templates, replicationcontroller templates, daemonset templates, etc..) in CI. Maybe someone know how to do it quickly?

Please add the option to lint a local chart. I want to lint changes to my chart before I commit push to any remote/local chart repo.

[varac]

Maybe I'd like to make mysewlf clearer: Afaik, chart-testing needs a remote chart repository which it can compare changes to right ? (Please provide a documentation which explains the basic principles)
I'd like to test a local chart without any remotes, a chart which has never been push to any repository.
Is this possible ?

I would also be interested in this.

I got it working locally by using docker and playing around with @ChristianWeissCG 's command:

First grab the image: docker pull quay.io/helmpack/chart-testing:v3.3.1

Then Inside the root of my repo I ran this command:

docker run -it --rm --name ct --volume $(pwd):/data quay.io/helmpack/chart-testing sh -c "cd /data; ct lint --config .circleci/chart-testing.yaml"

The repo looks somewhat like this:

.
├── .circleci
│   ├── chart-testing.yaml
│   ├── config.yml
├── my-chart
│   ├── Chart.yaml
│   ├── templates (folder, files not shown)
│   └── values.yaml

chart-testing.yaml:

chart-dirs:
  - my-chart
charts:
  - my-chart

The section of my circleci config I use for CI testing:

  lint-charts:
    docker:
      - image: quay.io/helmpack/chart-testing:v3.3.1
    steps:
      - checkout
      - run:
          name: lint
          command: |
            ct lint --config .circleci/chart-testing.yaml

if you have a chart in current directory and ct installed on the host then you can run:

ct install --chart-dirs . --charts .

With docker it works with:

docker run -it --workdir=/data --volume ~/.kube/config:/root/.kube/config:ro --volume $(pwd):/data quay.io/helmpack/chart-testing:v3.5.0 ct install --chart-dirs . --charts .

notice that workdir param is important and must be the same as volume mounted
