Changelog

The main changelog for the library versions can be found at https://github.com/cobbler/cobblerclient. This file is aiming to provide a logical overview about compatibility with the Cobbler server.

Cobbler 3.3.x support

v0.5.0 of this client introduced support for Cobbler v3.3.0, which was a refactor from runtime-created Python attributes to Python Properties. For further details see release notes. Breaking changes:

  • This client's support for earlier Cobbler versions was dropped.
  • next_server attribute is now either next_server_v4 or next_server_v6
  • boot_loader string attribute is now boot_loaders list
  • The following string attributes are now lists: FetchableFiles, KernelOptions, KernelOptionsPost, TemplateFiles, AutoinstallMeta, Repos

Cobbler <=3.2.x support

Retaining the below notes for the time-being, which only apply to v0.4.2 and earlier clients:

Cobbler (up to version 2.8.x) was written in Python2. However, Python2 is EOL since January 2020.
Cobbler 3 has been adapted to use Python3 and so lots of code changed. Sadly this also broke backward compatability with the original cobblerclient.

XMLRPC API changes

Function read_or_write_kickstart_template was replaced with:

  • read_autoinstall_template
  • write_autoinstall_template
  • remove_autoinstall_template

Function read_or_write_snippet was replaced with:

  • read_autoinstall_snippet
  • write_autoinstall_snippet
  • remove_autoinstall_snippet

Other changes

Template names used are now short names without a path.
So foo.ks instead of /var/lib/cobbler/kickstarts/foo.ks.

Renamed

These attributes are renamed in Cobbler 3:

  • kickstart to autoinstall
  • ks_meta to autoinstall_meta, but it is still used as a "legacy field"

These directories have been renamed:

  • /var/www/cobbler/ks_mirror to /var/www/cobbler/distro_mirror
  • /var/lib/cobbler/kickstarts to /var/lib/cobbler/templates

The storage locations for the json files changed from /var/lib/cobbler/config/{distros,profiles,systems,etc...}.d to /var/lib/cobbler/collections/{distros,profiles,systems,etc...}.

There is being worked on a script to migrate these: scripts/migrate-data-v2-to-v3.py.

Added

These fields have been added:

  • boot_loader - must be either grub, pxe, or ipxe

Removed

Support for these attributes was dropped in Cobbler 3:

  • ldap_enabled
  • ldap_type
  • monit_enabled
  • redhat_management_server
