Bare Metal Steps

For general deployments

  1. Review Requirements
    1. Machine requirements for a cluster with user-provisioned infrastructure
  2. Configure DNS.
    1. Example Bind Setup
  3. Configure HAProxy. Provision the required load balancers.
    1. Example HAProxy Configuration
  4. Configure webserver
    1. Example WebServer Configuration
  5. Configure PXE servers
    1. Example PXE Configuration
  6. Configure installer
    1. see script
  7. Configure ignition files
    1. see README.md
  8. Startup Machines
  9. View run OpenShift installer
  10. Reference Run OpenShift installer

For Static IP deployments
Use filetranspiler this will generate a igition json file with addtions from a fake root.

Example is from bootstrap node.

mkdir -p bootstrap/etc/sysconfig/network-scripts/

Create network inside this fakeroot. nYour interface may be different.

cat < bootstrap/etc/sysconfig/network-scripts/ifcfg-enp1s0
DEVICE=enp1s0
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.7.20
NETMASK=255.255.255.0
GATEWAY=192.168.7.1
DNS1=192.168.7.77
DNS2=8.8.8.8
DOMAIN=ocp4.example.com
PREFIX=24
DEFROUTE=yes
IPV6INIT=no
EOF

Using filetranspiler, create a new ignition file based on the one created by openshift-install.

filetranspiler -i bootstrap.ign -f bootstrap -o bootstrap-static.ign

Copy the ignition files to webserver.

This process needs to be done all all the nodes in the enviornment. Example configuration

tree /var/www/html/ignition/
├── bootstrap-static.ign
├── master0.ign
├── master1.ign
├── master2.ign
├── worker0.ign
└── worker1.ign

0 directories, 6 files

For static deployment you need to press tab on the CoreOS installer screen and edit the boot configuration with the following example.

ip=192.168.7.20::192.168.7.1:255.255.255.0:bootstrap:enp1s0:none:192.168.7.77
coreos.inst.install_dev=vda
coreos.inst.image_url=http://192.168.7.77:8080/install/rhcos-4.2.0-x86_64-metal-bios.raw.gz
coreos.inst.ignition_url=http://192.168.7.77:8080/ignition/bootstrap-static.ign
