This project does an rpm-ostree build inside a container; that container can then be pulled and run in a cluster, providing a HTTP server for clients to upgrade.
Locally (but see [README-development.md] for more information on builds)
$ docker build .
$ docker push SOME_IMAGE
Turn a CentOS Atomic AWS AMI booted machine into this OS:
- Launch an AMI for CentOS 7 (ami-a06447da) with at least 20GB disk (10GB is too small for now)
- Resize the disk:
$ lvextend -l +25%FREE atomicos/root
$ xfs_growfs /
- SSH to the machine and run:
$ docker run --network host -d -w /srv/tree/repo $REGISTRY/os:latest
$ ostree remote add --no-gpg-verify local http://localhost:8080 openshift/3.10/x86_64/os
$ rpm-ostree rebase -r local:openshift/3.10/x86_64/os
# wait, SSH back in
$ openshift version
Within a Kubernetes cluster, serve this content to nodes for upgrades:
$ kubectl run os-content --image=$REGISTRY/os:latest
$ kubectl expose os-content --port 8080
$ ssh root@NODE_HOST
$ ostree remote add --no-gpg-verify local http://os-content.namespace.svc:8080 openshift/3.10/x86_64/os
$ rpm-ostree rebase -r local:openshift/3.10/x86_64/os
# wait, SSH back in
$ openshift version
