| otubo | Hello folks, anyone working on adding man for config files? Or, is there an interest to do so? https://bugzilla.redhat.com/show_bug.cgi?id=1912862 | 09:07 |
|---|---|---|
| ubottu | bugzilla.redhat.com bug 1912862 in Red Hat Enterprise Linux 8 "Add man pages for cloud-init config files" [Low, New] | 09:07 |
| blackboxsw | otubo: not on our radar at the moment. Looking over that automated bug , most of those template files are just templates, which are written out to actual config files for other tools outside of cloud-init which *do* have existing man pages on the system. So, I'd drop the errors on all /etc/cloud/templates/* and any of the .d parts directory paths like /etc/rsyslog.d/, /etc/bash_completion.d/ and | 16:51 |
| blackboxsw | etc/NetworkManager/dispatcher.d/ | 16:51 |
| blackboxsw | those parts directories are man-doc'd for those separate utilities | 16:52 |
| blackboxsw | I could see extending man cloud-init to give a bit more information about configuring /etc/cloud/cloud.cfg and .d, but currently not on our radar. It's worth a bug/feature request asking for cloud.cfg(.d) docs though | 16:53 |
| blackboxsw | hrm, I'm also not really sure what to do about this fedora33 vs 34 bug on a cloudstack deployment https://bugs.launchpad.net/cloud-init/+bug/1942232 smells a bit to me like improper DNS config??? But I might be reading it wrong | 16:55 |
| ubottu | Launchpad bug 1942232 in cloud-init "CloudStack datasource: querying data-server does not work on Fedora 34" [Undecided, Incomplete] | 16:55 |
| minimal | is there anyway to prevent the "users:" section of user-data completely overriding entries in /etc/cloud.cfg, specifically I have "users: - default" in cloud.cfg but in someone places a "users" section in the user-data and forgets to ensure they put "-default" in there then the default user does not get created at all | 17:10 |
| blackboxsw | minimal: I admit I haven't done this directly, but I think you could lay down merge_how directives on disk in /etc/cloud/cloud.cfg or cloud.cfg.d/some.cfg that would define list behavior to append instead of "replace" | 17:13 |
| blackboxsw | https://cloudinit.readthedocs.io/en/latest/topics/merging.html | 17:13 |
| blackboxsw | as it is default for lists is to replace I believe. which explains your behavior | 17:13 |
| minimal | "As was the case before merging was implemented, user-data will overwrite conf.d configuration without merging." | 17:16 |
| minimal | doesn't this mean that merging will not work for /etc/cloud/cloud.cfg and user-data? | 17:16 |
| blackboxsw | minimal: d'oh "Note, however, that merge algorithms are not used across types of configuration" my bad. you are right | 17:20 |
| blackboxsw | hrm. in that case, seems not to be helped if users are defined lacking that root user in user-data. :/ | 17:21 |
| blackboxsw | s/root/default/ | 17:21 |
| minimal | not a big issue but would have been nice to ensure default user is always created | 17:21 |
| blackboxsw | thanks for reading the docs fully for me :/ | 17:21 |
| minimal | its a dirty job but someone's gotta do it ;-) | 17:22 |
| blackboxsw | heh. yeah I think the "feature" of this is that user-data **can** say it doesn't want the default user, via intentional omission. But I agree, it's probably more often that someone doesn't but that in and then has to hit up docs and mmmmmayybe, just maybe they find https://cloudinit.readthedocs.io/en/latest/topics/examples.html#including-users-and-groups "Unless you define users, you will get a 'ubuntu' user on ubuntu | 17:25 |
| blackboxsw | systems with the | 17:25 |
| blackboxsw | # legacy permission (no password sudo, locked user, etc). If however, you want | 17:25 |
| blackboxsw | # to have the 'ubuntu' user in addition to other users, you need to instruct | 17:25 |
| blackboxsw | # cloud-init that you also want the default user. To do this use the following" | 17:25 |
| blackboxsw | *It's probably more often accidental omission of - default"* | 17:26 |
| blackboxsw | probably worth us better documenting that in https://cloudinit.readthedocs.io/en/latest/topics/modules.html#users-and-groups | 17:27 |
| minimal | I'd expect most people would prefer a way in user-data to explicitly prevent the default user creation rather than needing to remember to add the "- default" bit but that's the way its always been so I guess we're stuck with it | 17:32 |
| otubo | blackboxsw, thanks a lot for the info on the man pages. I'll probably update the BZ early Monday. Have a nice weekend! :-) | 20:42 |
| blackboxsw | you too! | 20:42 |
