Pull the RPMs
　　Enable or reposync the rhel-7-server-extras-rpms Yum repository

• subscription-manager repos --enable=rhel-7-server-extras-rpms
  

　　-or-

• reposync --repoid rhel-7-server-extras-rpms --arch=x86_64 --newest-only --download_path=/repo/
  
• createrepo /repo/rhel-7-server-extras-rpms
  
• find /repo/rhel7-server-extras-rpm -type f -exec chmod 644 {} \;
  
• find /repo/rhel7-server-extras-rpm -type d -exec chmod 755 {} \;
  

　　Install Dependencies (Docker, Git, Go, Mercurial)

• yum install docker, git, golang, mercurial
  
• systemctl enable docker
  
• systemctl start docker
  

　　Download & Install etcd

• cd /opt
  
• git clone https://github.com/coreos/etcd
  
• cd /opt/etcd/
  
• ./build
  
• ln -s /opt/etcd/bin/etcd /usr/local/bin/
  

　　Download godep

• cd /opt
  
• GOPATH=/opt/godep go get github.com/tools/godep
  
• ln -s /opt/godep/bin/godep /usr/local/bin/
  

　　Download Kubernetes

• cd /opt
  
• git clone https://github.com/GoogleCloudPlatform/kubernetes.git
  

　　Note: If your RHEL7 machine is not registered with the Red Hat network, you may get an error in your logs saying /usr/share/rhel/secrets/rhel7.repo is not found. The workaround is to create the file as follows:

• touch /usr/share/rhel/secrets/rhel7.repo
  

　　Start Kubernetes

• /opt/kubernetes/hack/local-up-cluster.sh
  

Show what’s running in Kubernetes (nothing yet!)
　　Tell the client where the server is running

• sed -i -e ’s/^KUBERNETES_PROVIDER.*$/KUBERNETES_PROVIDER=“local”/’ /opt/kubernetes/cluster/kube-env.sh
  

　　List pods:

• /opt/kubernetes/cluster/kubecfg.sh list /pods
  

　　List services:

• /opt/kubernetes/cluster/kubecfg.sh list /services
  

　　List Replication Controllers:

• /opt/kubernetes/cluster/kubecfg.sh list /replicationControllers
  

　　Once you have this up and running, try deploying the GuestBook example: https://github.com/GoogleCloudPlatform/kubernetes/tree/master/examples/guestbook
