See https://issues.redhat.com/browse/MGMT-13669

Note that this repo is just a proof-of-concept. This repo is for debugging / experimenting with single node OpenShift relocation.

Note that single node OpenShift relocation is currently unsupported.

Install SNO cluster with bootstrap-in-place:

• Set PULL_SECRET environment variable to your pull secret

make start-iso

monitor the progress using make ssh and journalctl -f -u bootkube.service or kubectl --kubeconfig ./sno-workdir/auth/kubeconfig get clusterversion. The kubeconfig file can be found in .bootstrap-in-place/sno-workdir/auth/kubeconfig

• Once the installation is complete create the image template:

make bake

This will apply machine configs to the SNO instance and then shut it down

• Create the site-config iso wiht the configuration for the SNO instance at edge site:

make site-config.iso CLUSTER_NAME=new-name BASE_DOMAIN=foo.com

This will create the site-config.iso file, which will later get attached to the instance and once the instance is booted the installation-configuration.service will scan the attached devices, mount the iso, read the configuration and start the reconfiguration process.

• To copy the previous VM's image into /var/lib/libvirt/images/SNO-baked-image.qcow2 and then create a new SNO instance from it, with the site-config.iso attached, run:

make start-vm

• You can now monitor the progress using make ssh and journalctl -f -u installation-configuration.service
