Prepare the Hosts

The following packages should already be installed on the full version of Photon OS, but you might have to install them on the minimal version of Photon OS. If the tdnf command returns "Nothing to do," the package is already installed.

  • Install Kubernetes on all hosts--both photon-master and photon-node.
tdnf install kubernetes
  • Install iptables on photon-master and photon-node:
tdnf install iptables
  • Open the tcp port 8080 (api service) on the photon-master in the firewall
iptables -A INPUT -p tcp --dport 8080 -j ACCEPT
  • Open the tcp port 10250 (api service) on the photon-node in the firewall
iptables -A INPUT -p tcp --dport 10250 -j ACCEPT
  • Install Docker on photon-node:
tdnf install docker
  • Add master and node to /etc/hosts on all machines (not needed if the hostnames are already in DNS). Make sure that communication works between photon-master and photon-node by using a utility such as ping.
echo "    photon-master    photon-node" >> /etc/hosts
  • Edit /etc/kubernetes/config, which will be the same on all the hosts (master and node), so that it contains the following lines:
# Comma separated list of nodes in the etcd cluster

# logging to stderr routes it to the systemd journal

# journal message level, 0 is debug

# Should this cluster be allowed to run privileged docker containers
