Jonathan Lebon jlebon

Keybase proof

I hereby claim:

I am jlebon on github.
I am jlebon (https://keybase.io/jlebon) on keybase.
I have a public key whose fingerprint is A8B6 01C2 9DB5 7D90 2FF0 892F 936F 29E9 519C E313

To claim this, I am signing this object:

This gist is mostly based on the dnsmasq appendix from the openshift-training repo. However, I updated it and included fixes for the many gotchas I found along the way.

This is useful for folks who want to set up a DNS service as part of the cluster itself, either because they cannot easily change their DNS setup outside of the cluster, or just because they want to keep the cluster setup self-contained.

	Setting up:

	1. ostree remote add --set=gpg-verify=false centos-atomic-continuous https://ci.centos.org/artifacts/sig-atomic/rdgo/centos-continuous/ostree/repo/
	2. ostree pull centos-atomic-continuous:centos-atomic-host/7/x86_64/devel/continuous
	3. ostree commit -b my-test-branch --tree=ref=centos-atomic-continuous:centos-atomic-host/7/x86_64/devel/continuous
	(if your ostree has `refs --create`, then this can be shortened)
	4. ostree admin deploy my-test-branch
	5. reboot
