Kubernetes is an open source implementation of container cluster management.

Kubernetes Design Document

However, initial development was done on GCE and so our instructions and scripts are built around that. If you make it work on other infrastructure please let us know and contribute instructions/code.

1. You need a Google Cloud Platform account with billing enabled. Visit http://cloud.google.com/console for more details.

2. You must have Go installed: www.golang.org.

3. Ensure that your gcloud components are up-to-date by running gcloud components update.

4. Get the Kubernetes source:

    git clone https://github.com/GoogleCloudPlatform/kubernetes.git
   

The setup script builds Kubernetes, then creates Google Compute Engine instances, firewall rules, and routes:

cd kubernetes
hack/dev-build-and-up.sh

Once you have your instances up and running, the build-go.sh script sets up your Go workspace and builds the Go components.

The cloudcfg.sh script spins up two containers, running Nginx and with port 80 mapped to 8080:

cd kubernetes
hack/build-go.sh
cluster/cloudcfg.sh -p 8080:80 run dockerfile/nginx 2 myNginx

To stop the containers:

cluster/cloudcfg.sh stop myNginx

To delete the containers:

cluster/cloudcfg.sh rm myNginx

Assuming you've run hack/dev-build-and-up.sh and hack/build-go.sh:

cd kubernetes
cluster/cloudcfg.sh -c api/examples/task.json create /tasks

Where task.json contains something like:

{
  "ID": "nginx",
  "desiredState": {
    "image": "dockerfile/nginx",
    "networkPorts": [{
      "containerPort": 80,
      "hostPort": 8080
    }]
  },
  "labels": {
    "name": "foo"
  }
}

Look in api/examples/ for more examples

cd kubernetes
cluster/kube-down.sh

Or fork and start hacking!

If you have questions or want to start contributing please reach out. We don't bite!

The Kubernetes team is hanging out on IRC on the #google-containers room on freenode.net. We also have the google-containers Google Groups mailing list.

If you are a company and are looking for a more formal engagement with Google around Kubernetes and containers at Google as a whole, please fill out this form. and we'll be in touch.

# Before committing any changes, please link/copy these hooks into your .git

cd kubernetes
hack/test-go.sh

cd kubernetes
go tool cover -html=target/c.out

# You need an etcd somewhere in your path.
# To get from head:
go get github.com/coreos/etcd
go install github.com/coreos/etcd
sudo ln -s "$GOPATH/bin/etcd" /usr/bin/etcd
# Or just use the packaged one:
sudo ln -s "$REPO_ROOT/target/bin/etcd" /usr/bin/etcd

cd kubernetes
hack/integration-test.sh

One time after cloning your forked repo:

git remote add upstream https://github.com/GoogleCloudPlatform/kubernetes.git

Then each time you want to sync to upstream:

git fetch upstream
git rebase upstream/master

Install nodejs, npm, and raml2html, then run:

cd kubernetes/api
raml2html kubernetes.raml > kubernetes.html
