|
||
|
|
- init systeme können wie Editors ein sehr emotional schweres Thema sein. Bitte Diskussionen nach dem Talk.
|
||
|
|
- Geht auchähnlich mit anderen toolings wie Guix, heute aber Fokus auf systemd.</p></div><div class="bespoke-marp-note" data-index="1" tabindex="0"><p>- Weitere Features wie: integrierte Autoupdates, Pods und auch Desktop Anwendung
|
||
|
|
- Entwickelt von Redhat
|
||
|
|
- Keine "Enterprise Edition"
|
||
|
|
- Nutzt crun als runtime</p></div><div class="bespoke-marp-note" data-index="2" tabindex="0"><p>- Unit files beschreiben unter anderem:
|
||
|
|
- service
|
||
|
|
- socket
|
||
|
|
- timer
|
||
|
|
- etc
|
||
|
|
- Vereinheitlicht viel wie z.B. das log handling.
|
||
|
|
- Bei den meisten Linux Distributionen das default init system
|
||
|
|
- Debian
|
||
|
|
- RHEL, Fedora
|

|
|
- SUSE
|

|

|
|
- In Debian Stable aktuell noch 4.3, also kein Quadlet support</p></div><div class="bespoke-marp-note" data-index="5" tabindex="0"><p>- Container Section bietet fast alle Möglichkeiten, welche auch die CLI als Options bietet
|
||
|
|
- oder halt compose etc
|
||
|
|
- Timeout wichtig, damit genug Zeit um image zu pullen
|
||
|
|
- Kann einen schnell mal ins dockerhub ratelimit werfen, wenn z.B. Architektur nicht vorhanden.</p></div><div class="bespoke-marp-note" data-index="6" tabindex="0"><p>- Kann genauso wie bei Networks eine leere Datei sein</p></div><div class="bespoke-marp-note" data-index="7" tabindex="0"><p>- Kann genauso wie bei Volumes eine leere Datei sein</p></div><div class="bespoke-marp-note" data-index="9" tabindex="0"><p>- Klare Struktur heisst, die Dateien haben klar vordefinierte Verzeichnisse, nicht wie bei docker compose wilder Westen
|
||
|
|
- Verwaltung per systemctl und logs per journalctl
|
||
|
|
- In kombination mit MicroOS sind autoupdates sehr nice
|
||
|
|
- Man kann sich mit MicroOS und Podman, "stateless appliance" basteln</p></div><script>/*!! License: https://unpkg.com/@marp-team/marp-cli@4.1.1/lib/bespoke.js.LICENSE.txt */
