pivot ➰

pivot provides a simple command allowing you to upgrade an OSTree-based system from an OSTree repo embedded within a container image.

It's not intended to be run manually, but rather as part of the installation and upgrade process of a cluster. Though one can certainly test it today by provisioning an RHCOS node and running it directly.

Building

make build

OR

make static

Example Usage

pivot -r $REGISTRY/os:latest

Though normally, one wants to use digests rather than tags, e.g.:

pivot -r $REGISTRY/os@sha256:fdf70521df4ed1dc135d81fd3c4608574aeca45dc22d1b4e38d16630e9d6f1a7
