Pulp in an Offline Environment

Community
#1

I am looking at utilising pulp in an offline setting and wanted to ask some questions about its feasibility for this.

Would anyone be able to help answer the following:

  • Is there an export function to pull, either all repos, or specified ones?
  • If this is possible, are partial exports a possibility so that only smaller subsets of data are transferred?
  • Would any functionality break in pulp without connection to the internet?

Any help with the above questions would be greatly appreciated.

Good questions to start, I’ll attempt at briefly answering them here, but I urge you to scan the documentation on https://pulpproject.org/ .

  • Pulp Import Export (PIE) is there and can be used to transfer a subset (or all, but you need to list all) of repositories from one instance to another.
  • There is a concept of incremental export. It may or may not be exactly what you outlined there.
  • Pulp is perfectly able to run on an “air gaped” isolated network.

Support for PIE however varies from plugin to plugin.

Thank you very much for your swift response :grinning:

A followup question given your feedback, is it supported for both RPM and APT repos?

Think of it this way: You can use the full functionality of Pulp to manipulate repositories on your exporting Pulp instance before you export them. Also you may choose to export just a subset of repositories. So for example you might choose not to export the repositories you synchronize to on your exporting Pulp instance, but instead copy a subset of what was synchronized to a new repository and then export that.

Both pulp_rpm and pulp_deb have the export/import feature, but I am not 100% sure if there are any limitations on what can and cannot be exported.

Thank you both very much for your help.

I have created both Rocky (RPM) and Ubuntu (DEB) repositories. Whilst I’ve had no issues with the Rocky repo, I got this error whilst trying to export the Ubuntu repo:

ubuntu
ubuntu1045Ă—52 8.25 KB

Could I be missing a dependency, made a mistake or are Ubuntu repos not supported?

I am afraid I don’t have a full answer of the top of my head, and I don’t have time to investigate, which is why I will simply post what I do know for now: I know Ubuntu repositories can be exported. I don’t know if they can be exported via Pulp CLI or what the correct CLI syntax for doing so is.

I would guess, that the cli support is simply missing.
(“Capability” is a cli/glue concept.)

I did attempt using curl to create the exporter but got the same error.

I used the repo href and the error was identical :frowning:

Can you post a reproducer workflow (exact API commands you ran)?

And also what core/plugin versions do you have installed (can be found by running pulp status using the CLI)?
