Contributing to KubeDL
Welcome to KubeDL! We encourage you to help out by reporting issues, improving documentation, fixing bugs, or adding new features. Please also take a look at our code of conduct, which details how contributors are expected to conduct themselves as part of the KubeDL community.
As a contributor, if you want to make any contribution to KubeDL project, we should reach an agreement on the version of tools used in the development environment. Here are some dependents with specific version:
- Golang : v1.13+
- Kubernetes: v1.12+
KubeDL has enabled DCO ( Developer Certificate of Origin).
Thus, you will need to sign-off your commits in your pull requests.
Just add the
-s option in your
git commit and that will sign-off your commit automatically:
git commit -s -m 'This is my commit message'
KubeDL uses KubeBuilder for scaffolding code.
KubeDL code base consists of several components:
How to Build
Makefile in the root folder which describes the options to build and install. Here are some common ones:
Build the binary
If you run into any issues, try downloading the latest version of controller-gen command tools
go get email@example.com
Run controller locally
make manager # This command generates a binary called manager
Run the tests
Generate manifests: CRD, RBAC YAML files etc
Build the docker image
Replace the image name to your own image
export IMG=kubedl/kubedl:v0.3.0 && make docker-build
Push the image
Change the image name to your own image.
docker push kubedl/kubedl:v0.3.0
Generate the helm chart
Generate the helm chart, the helm chart will be generated under helm/kubedl
Add a new CRD
KubeBuilder to generate a CRD YAML file, for example, below command will generate a new kind
dog under api group
kubebuilder create api --group pet --version v1alpha1 --kind dog
Generate the zz_generated.deepcopy.go file
Generate the zz_generated.defaults.go file
go get k8s.io/code-generator/cmd/defaulter-gen
defaulter-gen -O zz_generated.defaults -i ./pet/... -h ../hack/boilerplate.go.txt
Get KubeDL Controller Pod Logs
kubectl logs kubedl-controller-manager-0 -n kubedl-system
Get KubeDL Controller Pod status
kubectl describe pod kubedl-controller-manager-0 -n kubedl-system
Git Preparation (Skip if you are familiar with Git)
To put forward a PR, we assume you have registered a GitHub ID. Then you could finish the preparation in the following steps:
- Fork the repository you wish to work on. You just need to click the button Fork in right-left of project repository main page. Then you will end up with your repository in your GitHub username.
- Clone your own repository to develop locally. Use
git clone https://github.com/<your-username>/kubedl.gitto clone repository to your local machine. Then you can create new branches to finish the change you wish to make.
- Set remote upstream to be
https://github.com/kubel-io/kubedl.gitusing the following two commands:
git remote add upstream https://github.com/kubedl-io/kubedl.git
git remote set-url --push upstream no-pushing
Adding this, we can easily synchronize local branches with upstream branches.
- Create a branch to add a new feature or fix issues
Update local working directory:
git fetch upstream
git checkout master
git rebase upstream/master
Create a new branch:
git checkout -b <new-branch>
Make any change on the new-branch then build and test your codes.
