Other thoughts?
Just for reference: to update Berlin build nodes I use this script:
https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/install-berlin.scm
It’s not great, but it’s been helpful.
thanks for sharing! (even if I can still barely understand what your
script does)
I understand most parts of it ;)
It is a real beauty and a testiment to the power of Guix and Guile.
actually mainenance.git is full of treasures :-)
Berlin consists of a head node and many almost identical servers.
AFAIU remote servers could be completely different each other for your
script to do its job, or am I missing something?
Besides the host-ips being hardcoded and the
(berlin-build-machine-os) procedure from
(sysadmin build-machines) and the keys from
(sysadmin people) it seems pretty generic.
Ricardo, is (define (reconfigure-remote id guix-directory) dead code
that could be commented out/removed?
To
update one or more servers I run the script on the head node, which
generates operating system configuration variants for each of the
requested servers, builds the systems (offloading to all of the
connected build nodes), copies the system closures to the target
systems, and then runs “reconfigure” on the targets.
explained this way seems easy :-O
Since the operating system configuration record cannot be
serialized,
is there any plan or wip on this kind of serialization?
the build nodes need to have a copy of the code that’s used to
generate
the operating system configuration. Not great. (They only need it
to
run “reconfigure”; they wouldn’t need that if
“reconfigure” could
operate remotely.)
"just" having a "guix system reconfigure --host <remote-hostname/IP>"
would be a *huge* feature
Agreed, but we would need to supply both keys and generic-config to
this command as well.
Anyway, I thought I’d share this with y’all.
IMHO your remote host configuration technique deserves a dedicated
blog
article... but I've already asked too much :-)
Good idea!
