OPENSTACK-C...ION.SERVICE(8)

πŸ“¦ version 9.0.0, in epel 10

πŸ’… openstack-completion.service β€” a Gen Z field guide (section 8, System Administration, bestie)

okay so real talk: this page is OPENSTACK-C...ION.SERVICE(8) from the System Administration corner of the manual, and it's about a service that does exactly one thing and does it iconically. Let's get into it. ✨


🌸 NAME 🌸

openstack-completion.service β€” she regenerates your OpenStack bash completion. That's the whole job. That's the whole vibe. πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

systemctl start openstack-completion.service

one line, no drama, no flags, no arguments. you literally just start her and she goes. periodt. πŸ’…


✨ DESCRIPTION ✨

openstack-completion.service is a oneshot systemd service β€” so she runs once, does her thing, and dips. what is her thing? regenerating the OpenStack unified CLI bash completion script by introspecting all currently installed OpenStack client entry points. yes she's doing that. she's doing the introspection. πŸ”₯

the completion script gets written atomically, which is the fancy way of saying she's not messy about it: first a temporary file gets created in /run/openstack-client/, and then it gets moved into place at /var/lib/openstack-client/bash-completion. the way that matters 😭 β€” it means a failed run will never leave a broken or truncated completion file just sitting there lying to you. atomic writes ate, honestly.

she runs as the openstack-completion system user, and requires no elevated privileges. lowkey the most chill service in the whole stack. 🫢


🧚 FILES 🧚

  • /var/lib/openstack-client/bash-completion β€” the generated bash completion script, containing the _openstack function plus all the command data for whatever components are currently installed. this is the main character file. πŸ‘‘
  • /usr/lib/bash-completion/completions/openstack β€” the static bash completion entry point that sources the generated file. she's the plug, not the whole operation. πŸ”Œ
  • /usr/lib/sysusers.d/openstack-completion.conf β€” the sysusers.d configuration that creates the openstack-completion system user. gotta have a user to run as, and this is where she comes from. 🌈

πŸ’œ SEE ALSO πŸ’œ

  • openstack(1) β€” go read the actual CLI she's completing for, iykyk.

ngl the whole takeaway is: oneshot service, atomic write, no root needed, three files, one SEE ALSO. slay. πŸ’–

okay that's the page!! source/version is OpenStack Client and the manual date line is just the section-8 footer, so nothing extra to report bestie β€” go forth and get your completions regenerated. πŸ“β­
