Install GOLang (latest version):
sudo wget https://golang.org/dl/go1.16.5.linux-amd64.tar.gz
rm -rf /usr/local/go && tar -C /usr/local -xzf go1.16.5.linux-amd64.tar.gz
Setup the environment via Bash :
echo 'export PATH=${PATH}:/usr/local/go/bin' >> ~/.profile
echo 'export GOPATH_K8S=${HOME}/go/src/k8s.io/kubernetes' >> ~/.profile
echo 'export PATH=${GOPATH_K8S}/third_party/etcd:${PATH}' >> ~/.profile
source ~/.bashrc
MAKE SURE YOU HAVE SET THE PATH FOR BOTH GO AND ETCD IN THE SECURE_PATH IN THE /etc/sudoers FILE
MAKE SURE TO EDIT IT AS VISUDO
clone kubernetes
mkdir -p {GOPATH_K8S}
git clone https://github.com/kubernetes/kubernetes ${GOPATH_K8S}
git remote rename origin upstream
install etcd
$ hack/install-etcd.sh
start docker demon
systemctl enable docker
systemctl start docker
Build k8s
This step takes 15 minitues
cd ${GOPATH_K8S}
git checkout v1.12.3 (checkout the stable release version)
time make quick-release
Run a Local k8s cluster
$ {GOPATH_K8S}/hack/local-up-cluster.sh
verify the cluster is running in another window
export KUBERNETES_PROVIDER=local
export KUBECONFIG=/var/run/kubernetes/admin.kubeconfig
${GOPATH_K8S}/cluster/kubectl.sh get nodes
Fork the k8s repo on github
navigate to
click fork button
setup gihub user name
export GITHUB_USER=[Insert your github user name]
echo 'export GITHUB_USER=${GITHUB_USER}' >> ~/.bash_profile
Change the k8s source code
Navigate to the directory your clone
cd ${GOPATH_K8S}
git remote add origin https://github.com/${GITHUB_USER}/kubernetes
git fetch origin
These instructions make the folllowing assumptions:
-Your upstream remote going to
http://
-Your origin remote
http://
you can double check by runnig
$ git remote -v
Create a new branch before making a change
branch should have some meaning means what you have added to the code
git checkout upstream/master
git checkout -b my-brnach-of-k8s
If you would like to make change we recommend finding some untested code and adding a few unit tests. If you don't know how to write unit tests in go read this
Example new test
File: pkg/util/normalizer/normalizer_test.go
Run Kubernetes Locally
$ make test WHAT-k8s.io/kubernetes/pkg/util/normalizer
Contribute a pull request
Commit your changes and push to your fork
gofmt -v [insert path to changed file]
gofmt -v pkg/util/normalizer/normalier_test.go
git add .
git config --global user.name ""
git config --global user.email ""
git commit -m "commit msg"
git push -u origin/my-branch-of-k8s
create a pull request via GiHub UI
Navigate to https://github.com/kubernetes/kubernetes page
click on the new pull request
click on compare across forks link
select your fork and branch from the two dropdowns on the right
click on create pull request
Note that an existing maintainer must comment with the /ok-to-test comment the automated test for new contributer
If you have any doubt please ASK .
