Testing tips

If you are running kops as part of an e2e test, the following tips may be useful.

CI Kubernetes Build

Set the KubernetesVersion to a http:// or https:// base url, such as https://storage.googleapis.com/kubernetes-release-dev/ci/v1.4.0-alpha.2.677+ea69570f61af8e/

We expect the base url to have bin/linux/amd64 directory containing:

• kubelet
• kubelet.sha1
• kubectl
• kubectl.sha1
• kube-apiserver.docker_tag
• kube-apiserver.tar
• kube-apiserver.tar.sha1
• kube-controller-manager.docker_tag
• kube-controller-manager.tar
• kube-controller-manager.tar.sha1
• kube-proxy.docker_tag
• kube-proxy.tar
• kube-proxy.tar.sha1
• kube-scheduler.docker_tag
• kube-scheduler.tar
• kube-scheduler.tar.sha1

Do this with kops edit cluster <clustername>. The spec should look like

...
spec:
  kubernetesVersion: "https://storage.googleapis.com/kubernetes-release-dev/ci/v1.4.0-alpha.2.677+ea69570f61af8e/"
  cloudProvider: aws
  etcdClusters:
  - etcdMembers:
    - name: us-east-1c
      zone: us-east-1c
    name: main
...

Running the kubernetes e2e test suite

The e2e directory has a docker image and some scripts which make it easy to run the kubernetes e2e tests, using kops.

Uploading a custom build

If you want to upload a custom build, here is one way to do so:

make quick-release
cd ./_output/release-tars/
# ??? rm -rf kubernetes/
tar zxf kubernetes-server-linux-amd64.tar.gz

rm kubernetes/server/bin/federation*
rm kubernetes/server/bin/hyperkube
rm kubernetes/server/bin/kubeadm
rm kubernetes/server/bin/kube-apiserver
rm kubernetes/server/bin/kube-controller-manager
rm kubernetes/server/bin/kube-discovery
rm kubernetes/server/bin/kube-dns
rm kubernetes/server/bin/kubemark
rm kubernetes/server/bin/kube-proxy
rm kubernetes/server/bin/kube-scheduler
rm kubernetes/kubernetes-src.tar.gz


find kubernetes/server/bin -type f -name "*.tar" | xargs -I {} /bin/bash -c "sha1sum {} | cut -f1 -d ' ' > {}.sha1"
find kubernetes/server/bin -type f -name "kube???" | xargs -I {} /bin/bash -c "sha1sum {} | cut -f1 -d ' ' > {}.sha1"

aws s3 sync  --acl public-read  kubernetes/server/bin/ s3://${S3_BUCKET_NAME}/kubernetes/dev/bin/linux/amd64/

Then:

• kops create cluster ... --kubernetes-version https://${S3_BUCKET_NAME}.s3.amazonaws.com/kubernetes/dev/

• for an existing cluster: kops edit cluster and set KubernetesVersion to https://${S3_BUCKET_NAME}.s3.amazonaws.com/kubernetes/dev/
