[Spacewalk-list] [EXTERNAL] Cloning errata to cloned channel using spacecmd

Fri May 8 14:24:35 UTC 2020

I don’t know that you can really gracefully do this with spacecmd.  I run through the API to do a clone as of today operation.

Be aware that there is a rather significant issue with cloned errata.  It’s not in the first stage clone, it’s second stage and beyond.  Errata can be downloaded or applied to download channels, and cloned down to your development channels gracefully.  If you clone errata from dev to QA, (this is the problem,) I’ve noted for years that packages referenced in the errata may be brought into the channel even if they do not apply to the channel.  The big issue is bringing EL7 packages into an EL6 channel, and the like.  To remediate this, clone the errata in the 2nd stage of your pipeline, then immediately compare channel package contents and make this channel look like it’s clone source.

Thanks Dean.  I have seen solutions using a similar method when googling.  I am just being lazy and was hoping that there was a command like 'softwarechannel_sync_errata[_tree] <CHANNEL>' that would perform the same function as clicking the "Clone Errata" in the Web UI.  Maybe I need to submit an RFE.  ;-)

Cheers,
Ted

Hi Ted,
I use a combination of spacewalk-report and spacewalk-clone-by-date (from the spacewalk-utils package) to clone my channels  DEV -> QA -> PROD based on the date.

Hi All,

I have been googling around and I haven’t been able to find an answer to my question.

I have cloned "oraclelinux7-x86_64" channel to "qa-oraclelinux7-x86_64" a few weeks ago and now I want to sync the new errata in original channel to the QA channel.  In the past I have used the web interface going to Manage Software Channels ---> Channel Name ---> Errata tab ---> Clone and then clicked on "Clone Errata" to clone them from the original channel.  Or I have used a python script I wrote years ago which does a client.channel.software.mergePackages.

I am interested in seeing if I can accomplish the same using 'spacecmd'

I have tried running "spacecmd softwarechannel_errata_sync oraclelinux7-x86_64 qa-oraclelinux7-x86_64", however from the output it looks like it wants to remove all of the errata in the channel and replace it instead of just adding the missing errata.  For example:

summary:
  oraclelinux7-x86_64:  2412 errata
  qa-oraclelinux7-x86_64:  2402 errata
    add     2412 errata to   qa-oraclelinux7-x86_64
    remove  2402 errata from qa-oraclelinux7-x86_64

I did notice that the errata in the cloned channel has "CL-" prepended to the name:

# spacecmd softwarechannel_errata_diff oraclelinux7-x86_64 qa-oraclelinux7-x86_64 | grep 2020-1116

-ELSA-2020-1116 Important:  qemu-kvm security, bug fix, and
+CL-ELSA-2020-1116 Important:  qemu-kvm security, bug fix, and

So I am assuming that is the cause of the behavior.

Is there a way to use spacecmd to just add the missing errata?

Thanks in advance!!

Cheers,
Ted
