- $OCP_Y_VERSIONAn example to use this repo to create a SNO running on KVM, and install the ZTP required opertators so to act as a ZTP hub.
## Create VM
ssh 192.168.58.14 kcli stop vm hub
ssh 192.168.58.14 kcli delete vm hub -y
ssh 192.168.58.14 'kcli create vm -P uuid=11111111-1111-1111-1234-000000000000 -P start=False -P memory=20480 -P numcpus=16 -P disks=[150] -P nets=["{\"name\":\"br-vlan58\",\"nic\":\"eth0\",\"mac\":\"de:ad:be:ff:10:85\"}"] hub'
ssh 192.168.58.14 kcli list vm
systemctl restart sushy-tools.service
## Generate ISO, config-hub.yaml turn on all ZTP required operators but turn off others
rm -f ~/.cache/agent/image_cache/coreos-x86_64.iso
rm -rf hub
./sno-iso.sh samples/ztp-hub-on-sno/config-hub.yaml
cp hub/agent.x86_64.iso /var/www/html/iso/hub.iso
## Install OCP
./sno-install.sh samples/ztp-hub-on-sno/config-hub.yaml
oc get node --kubeconfig hub/auth/kubeconfig
oc get clusterversion --kubeconfig hub/auth/kubeconfig
echo "Installation in progress, please check it in 30m."
## Run extra manifests
oc --kubeconfig hub/auth/kubeconfig apply -k ./extra-manifests
