Hello everyone.
I've created a small job (not yet enabled)
that gets an rpm and then deploys it to the static repo at resources.ovirt.org
for this I've sent this patch http://gerrit.ovirt.org/#/c/33863/
that will add the "resources" user. it will have permissions only for the static
rpms directory and will scp the files to there.
is it acceptable by everybody security-wise?
thanks
Ohad

Adding security list to the loop.

Hi, thanks for this. I'm a bit confused though. Is this pertaining to the
infrastructure for the oVirt project, or is this code going into the oVirt code itself
that is then consumed by downstream users? I only ask because of the reference to
resources.ovirt.org so I'm unsure whether this is a code question or an infrastructure
question.
Can you please advise?

It's infrastructure question

It's infrastructure question
let me try to clarify.
today our continuous delivery process is async partially:
- jenkins.ovirt.org builds and publish the rpms into resources.ovirt.org under jenkins
home (unprivileged user).
- a cron job scans the target dir and checks if new rpms are there (via flag used by the
script) and updates the repos accordingly.
the idea behind this is not to allow direct access from jenkins to resources.ovirt.org via
ssh.
now what ohad is suggesting is to change the process and ALLOW direct access to certain
repositories under resources.ovirt.org, with the following changes:
- new user will be used - resources
- the user will have limited sudo access only to read/write to the relevant repository
(static repos)
- no cron job will run async to update it.
so the question is are we comfortable with this change? is it safe or has the same
security level as the current async one?
if its safe we might consider changing the original flow as well to be synced and not use
a cron job.
your input is appreciated,
Eyal.

hanges:

your input is appreciated,
As far as I know, the only reason we had to use the cron (kiril might
know better, but he does not work with us anymore) was to avoid
exposing the signing key for the packages to the jenkins ssh user, but
that part was never automated anyhow and the nightly-static packages
are not signed.
So I think that creating a new user without privileges to mess
anything up (only access to the nightly repos) is as secure as the
cron approach, but more convenient.
In the future I'm thinking on using a simple web service to deploy the
rpms, that way the clients do not need ssh access to the machine at
all. But that's not ready yet.
