Joe Beda 894a7e3282 Move everything out of src and reorganize scripts.

Fixed up some scripts to be more robust.  Changed the e2e test setup to use g1-small instances.  Fixed up documentation to reflect the new script locations.  Disabled the "curl | bash" cluster launch as it hasn't been well tested and doesn't include the cloudcfg tool yet.

Kubernetes

Kubernetes is an open source reference implementation of container cluster management.

Getting started on Google Compute Engine

Prerequisites

You need a Google Cloud Platform account with billing enabled. Visit http://cloud.google.com/console for more details
You must have Go installed: www.golang.org
Ensure that your gcloud components are up-to-date by running gcloud components update.
Get the Kubernetes source: git clone https://github.com/GoogleCloudPlatform/kubernetes.git

Setup

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

Running a container (simple version)

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

This will spin up two containers running Nginx mapping port 80 to 8080.

To stop the container:

cluster/cloudcfg.sh stop myNginx

To delete the container:

cluster/cloudcfg.sh rm myNginx

Running a container (more complete version)

cd kubernetes
cluster/cloudcfg.sh -c 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 the examples/ for more examples

Tearing down the cluster

cd kubernetes
cluster/kube-down.sh

Development

Hooks

# Before committing any changes, please link/copy these hooks into your .git
# directory. This will keep you from accidentally committing non-gofmt'd
# go code.
cd kubernetes
ln -s "../../hooks/prepare-commit-msg" .git/hooks/prepare-commit-msg
ln -s "../../hooks/commit-msg" .git/hooks/commit-msg

Unit tests

cd kubernetes
hack/test-go.sh

Coverage

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

Integration tests

# 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

Keeping your development fork in sync

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

Regenerating the documentation

Install nodejs, npm, and raml2html, then run:

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