To Reproduce:

• Install Fedora 27 from https://cloud.fedoraproject.org/ (GP2 image) on AWS:
  • m4.large
  • Disk: at least 50GiB
  • ssh: ssh -i ~/.ssh/$KEY fedora@$IP
• Start a kube-spawn v.0.2.0 Kubernetes cluster on the AWS EC2 instance:

export KUBERNETES_VERSION=v1.7.5 # or you can try v1.8.4 ...
sudo setenforce 0
sudo dnf install -y btrfs-progs git go iptables libselinux-utils polkit qemu-img systemd-container
mkdir go
export GOPATH=$HOME/go
go get -u github.com/containernetworking/plugins/plugins/...
export CNI_PATH=$GOPATH/bin
mkdir -p $GOPATH/src/github.com/kinvolk/kube-spawn
curl -sSLO https://github.com/kinvolk/kube-spawn/releases/download/v0.2.0/kube-spawn-v0.2.0.tar.gz
tar xf kube-spawn-v0.2.0.tar.gz
cp kube-spawn-v0.2.0/kube-spawn-runc $GOPATH/src/github.com/kinvolk/kube-spawn/kube-spawn-runc
sudo cp kube-spawn-v0.2.0/{cni-noop,cnispawn,kube-spawn} /bin/
sudo -E kube-spawn create --nodes=3 --kubernetes-version $KUBERNETES_VERSION
sudo -E kube-spawn start
export KUBECONFIG=/var/lib/kube-spawn/default/kubeconfig
sudo curl -Lo /usr/local/bin/kubectl https://storage.googleapis.com/kubernetes-release/release/${KUBERNETES_VERSION}/bin/linux/amd64/kubectl
sudo chmod +x /usr/local/bin/kubectl
kubectl get nodes # repeat until the nodes are "Ready"
kubectl version > version.txt

• Run Sonobuoy with the command:

curl -L https://raw.githubusercontent.com/cncf/k8s-conformance/master/sonobuoy-conformance.yaml | kubectl apply -f -

• Wait until the sonobuoy pods are running:

kubectl get pods --all-namespaces

• Check the filename of the Sonobuoy report with kubectl logs -f -n sonobuoy sonobuoy
  • It might take a while...
  • Visible with Results available at /tmp/sonobuoy/2017....tar.gz
• Copy it with kubectl cp
  • kubectl cp sonobuoy/sonobuoy:/tmp/sonobuoy/2017....tar.gz 2017....tar.gz
