This doc explains how to build, test and release ingress controllers.
All ingress controllers are built through a Makefile. Depending on your requirements you can build a raw server binary, a local container image, or push an image to a remote repository.
Build a raw server binary
$ make controller
Build a local container image
$ make container TAG=0.0 PREFIX=$USER/ingress-controller
Push the container image to a remote repository
$ make push TAG=0.0 PREFIX=$USER/ingress-controller
The build should use dependencies in the ingress/vendor
directory.
Occasionally, you might need to update the dependencies.
$ godep version
godep v74 (linux/amd64/go1.6.1)
$ go version
go version go1.6.1 linux/amd64
This will automatically save godeps to vendor/
$ godep save ./...
If you have an older version of godep
$ go get github.com/tools/godep
$ cd $GOPATH/src/github.com/tools/godep
$ go build -o godep *.go
In general, you can follow this guide to update godeps. To update a particular dependency, eg: Kubernetes:
cd $GOPATH/src/github.com/kubernetes/ingress
godep restore
go get -u github.com/kubernetes/kubernetes
cd $GOPATH/src/github.com/kubernetes/kubernetes
godep restore
cd $GOPATH/src/github/kubernetes/ingress
rm -rf Godeps
godep save ./...
git [add/remove] as needed
git commit
To run unittets, enter each directory in controllers/
$ cd $GOPATH/src/k8s.io/ingress/controllers/gce
$ go test ./...
If you have access to a Kubernetes cluster, you can also run e2e tests
$ cd $GOPATH/src/k8s.io/kubernetes
$ ./hack/ginkgo-e2e.sh --ginkgo.focus=Ingress.* --delete-namespace-on-failure=false

All Makefiles will produce a release binary, as shown above. To publish this
to a wider Kubernetes user base, push the image to a container registry, like
gcr.io. All release images are hosted under gcr.io/google_containers
and
tagged according to a semver scheme.
An example release might look like:
$ make push TAG=0.8.0 PREFIX=gcr.io/google_containers/glbc
Please follow these guidelines to cut a release:
- Update the release page with a short description of the major changes that correspond to a given image tag.
- Cut a release branch, if appropriate. Release branches follow the format of
controller-release-version
. Typically, pre-releases are cut from HEAD. All major feature work is done in HEAD. Specific bug fixes are cherrypicked into a release branch. - If you're not confident about the stability of the code, tag it as alpha or beta. Typically, a release branch should have stable code.
