Hi,
when creating our Atomic test images, we want to first run "atomic host
upgrade" and then "ostree checkout $ref /var/local-tree". We do this so
that we can modify /var/local-tree via rpm and boot into it to run the
tests.
What should $ref be so that /var/local-tree will be the same as what
"atomic host upgrade" has just downloaded and deployed for the next
boot?
We used dig it out of /usr/share/rpm-ostree/treefile.json, giving
something like:
rhel-atomic-host/7/x86_64/standard
or
fedora-atomic/f23/x86_64/docker-host
This used to "work", but since recently this command
ostree checkout rhel-atomic-host/7/x86_64/standard /var/local-tree
gives us the currently booted tree, not the one produced by "atomic host
upgrade".
Now we need to prefix the remote as well, like this:
ostree checkout \
rhel-atomic-host-ostree:rhel-atomic-host/7/x86_64/standard \
/var/local-tree
"atomic host upgrade" has a way to compute this refspec. How can we
reliably get the same value?
Or is there a better way to achieve what we want?
Thanks in advance!
