How to build kubebuilder locally

Note that, by building the kubebuilder from the source code we are allowed to test the changes made locally.

  1. Run the following command to clone your fork of the project locally in the dir /src/sigs.k8s.io/kubebuilder
$ git clone git@github.com:<user>/kubebuilder.git $GOPATH/src/sigs.k8s.io/kubebuilder
  1. Ensure you activate module support before continue ($ export GO111MODULE=on)
  2. Run the command make install to create a bin with the source code

NOTE In order to check the local environment run make go-test.

What to do before submitting a pull request

  1. Run the script make generate to update/generate the mock data used in the e2e test in $GOPATH/src/sigs.k8s.io/kubebuilder/testdata/

IMPORTANT: The make generate is very helpful. By using it, you can check if good part of the commands still working successfully after the changes. Also, note that its usage is a pre-requirement to submit a PR.

Following the targets that can be used to test your changes locally.

Command Description Is called in the CI?
make go-test Runs go tests no
make test Runs tests in shell (./test.sh) yes
make lint Check the code implementation yes
make test-coverage Run coveralls to check the % of code covered by tests yes
make check-testdata Checks if the testdata dir is updated with the latest changes yes

NOTE To use the make lint is required to install golangci-lint locally. More info: https://github.com/golangci/golangci-lint#install

Where the CI Tests are configured

  1. See the Travis file to check its tests and the scripts used on it.
  2. Note that the prow tests used in the CI are configured in kubernetes-sigs/kubebuilder/kubebuilder-presubmits.yaml.
  3. Check that all scripts used by the CI are defined in the project.

How to contribute to docs

We currently have 2 production branches, book-v2 and book-v1. book-v2 maps to book.kubebuilder.io which contains our latest released features, while book-v1 maps to book-v1.book.kubebuilder.io, which contains our legacy docs for kubebuilder V1.

Docs for unreleased features live in the master branch. We merge the master branch into the book-v2 branch when doing the releases.

If adding doc for an unreleased feature, the PR should target master branch. If updating existing docs, the PR should target master branch and then cherry-picked into book-v2 branch.

How to preview the changes performed in the docs
