Setup OKD (Origin Community Distribution) RedHat OpenShift FOSS distro on Centos 7

Emad R

Hi,

Been time since I posted something... trying to find a job in Toronto, and not purchasing everything I see here.

So this is an easy and insecure way to set it up in one server for testing and no need for FQDN. I highly recommend Vultr high freq VMs, at least the 24$ one with 4 GB RAM, the more the better.
Start from latest Centos 7:

yum update -y
yum install -y epel-release
yum install -y lsof glances net-tools htop nano yum-utils wget rsync git ncdu nload mc p7zip tuned iotop mdadm unzip iperf3 mlocate tree
sed -i 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/selinux/config
sed -i 's/installonly_limit=5/installonly_limit=2/g' /etc/yum.conf
timedatectl set-timezone Asia/Amman
shutdown -r now
yum clean all && yum autoremove

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install -y  docker-ce docker-ce-cli containerd.io docker-compose

sudo usermod -aG docker $USER
newgrp docker

sudo mkdir /etc/docker /etc/containers

nano /etc/containers/registries.conf
---
[registries.insecure]
registries = ['172.30.0.0/16']
---

nano /etc/docker/daemon.json
---
{
   "insecure-registries": [
     "172.30.0.0/16"
   ]
}
---

sudo systemctl daemon-reload
sudo systemctl restart docker
sudo systemctl enable docker

echo "net.ipv4.ip_forward = 1" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

firewall-cmd --permanent --delete-zone dockerc
firewall-cmd --permanent --new-zone dockerc
DOCKER_BRIDGE=`docker network inspect -f "{{range .IPAM.Config }}{{ .Subnet }}{{end}}" bridge`
firewall-cmd --permanent --zone dockerc --add-source $DOCKER_BRIDGE
firewall-cmd --permanent --zone dockerc --add-port=1-65535/udp
firewall-cmd --permanent --zone dockerc --add-port=1-65535/tcp
firewall-cmd --permanent --zone=public --add-port=1-65535/udp
firewall-cmd --permanent --zone=public --add-port=1-65535/tcp
firewall-cmd --reload
systemctl restart firewalld

wget https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz
tar xvf openshift-origin-client-tools*.tar.gz
cd openshift-origin-client*/
sudo mv  oc kubectl  /usr/local/bin/
oc version

oc cluster up --public-hostname='SERVERPUBIP' --routing-suffix='SERVERPUBIP.xip.io'

Thats it, be sure to replace

SERVERPUBIP with your Server Public IP
Asia/Amman and with your Timezone
Omit --- in nano commands, don't type those.
