Le projet vise \u00e0 fournir une plateforme pr\u00eate \u00e0 l'emploi pour les fournisseurs de services d'h\u00e9bergement et un cadre pour la construction de clouds priv\u00e9s et publics. La plateforme s'installe directement sur les serveurs et couvre tous les aspects de la pr\u00e9paration de l'infrastructure pour la fourniture de services g\u00e9r\u00e9s. Cozystack permet de lancer et de fournir des clusters Kubernetes, des bases de donn\u00e9es et des machines virtuelles. Le code de la plateforme est disponible sur GitHub et est distribu\u00e9 sous la licence Apache-2.0.      <\/p>\n<p>Le stack technologique de base utilise Talos Linux et Flux CD. Les images du syst\u00e8me, du noyau et des modules n\u00e9cessaires sont pr\u00e9par\u00e9es \u00e0 l'avance et mises \u00e0 jour de mani\u00e8re atomique, ce qui permet d'\u00e9viter des composants comme dkms et les gestionnaires de paquets, garantissant ainsi une stabilit\u00e9 de fonctionnement. Une m\u00e9thode d'installation simple est fournie dans un data center vide gr\u00e2ce \u00e0 PXE et \u00e0 l'installateur debian-like talos-bootstrap. Dans le cadre de la plateforme, il est possible de d\u00e9ployer en un clic des services tels que Kafka, FerretDB, PostgreSQL, Cilium, Grafana, Victoria Metrics et d'autres.       <\/p>\n<p>La plateforme inclut une impl\u00e9mentation libre <a href=\"https:\/\/prohoster.info\/fr\/server\/dts-sofia\/\"  data-wpil-monitor-id=\"401\">de l'infrastructure r\u00e9seau<\/a> (fabric) bas\u00e9 sur Kube-OVN, et utilise Cilium pour organiser le r\u00e9seau de services, MetalLB pour l'annonce des services \u00e0 l'ext\u00e9rieur. Le stockage est r\u00e9alis\u00e9 sur LINSTOR, o\u00f9 ZFS est propos\u00e9 comme couche de base pour le stockage et DRBD pour la r\u00e9plication. Un stack de surveillance pr\u00e9configur\u00e9 bas\u00e9 sur VictoriaMetrics et Grafana est disponible. Pour le lancement des machines virtuelles, la technologie KubeVirt est utilis\u00e9e, permettant de lancer des machines virtuelles classiques directement dans des conteneurs Kubernetes, et dispose d\u00e9j\u00e0 de toutes les int\u00e9grations n\u00e9cessaires avec Cluster API pour le lancement de clusters Kubernetes g\u00e9r\u00e9s \u00e0 l'int\u00e9rieur du cluster Kubernetes \u00ab physique \u00bb.      <\/p>\n<p>Dans cette nouvelle version :  <\/p>\n<ul>\n<li class=\"l\"> Un planificateur LINSTOR a \u00e9t\u00e9 ajout\u00e9 pour un placement optimal des pods. Un &#171;scheduler extender&#187; d\u00e9di\u00e9 pour Kubernetes fonctionne en sync avec le planificateur standard de Kubernetes et aide \u00e0 placer les pods de mani\u00e8re optimale sur les n\u0153uds avec le stockage LINSTOR. Lorsque un pod demande un volume LINSTOR, le planificateur se renseigne aupr\u00e8s du contr\u00f4leur LINSTOR sur les n\u0153uds o\u00f9 se trouvent des r\u00e9pliques locales des volumes requis. La priorit\u00e9 est donn\u00e9e aux n\u0153uds o\u00f9 les donn\u00e9es sont d\u00e9j\u00e0 pr\u00e9sentes, ce qui minimise le trafic r\u00e9seau et am\u00e9liore la performance I\/O. De plus, un webhook d'admission a \u00e9t\u00e9 mis en place, qui dirige automatiquement les pods utilisant des volumes CSI LINSTOR vers le planificateur d\u00e9di\u00e9, assurant une int\u00e9gration fluide sans r\u00e9glage manuel.\n<li class=\"l\"> Stockage SeaweedFS SeaweedFS a \u00e9t\u00e9 mis \u00e0 jour vers la version 4.05, dans laquelle l'optimisation du trafic S3 (localit\u00e9 du trafic) a \u00e9t\u00e9 r\u00e9alis\u00e9e : les requ\u00eates sont d\u00e9sormais dirig\u00e9es vers les serveurs les plus proches, r\u00e9duisant ainsi les latences et acc\u00e9l\u00e9rant le fonctionnement du stockage. Un nouveau composant d'administration avec interface web et support de l'autorisation a \u00e9galement \u00e9t\u00e9 ajout\u00e9, ainsi que des workers pour l'ex\u00e9cution de t\u00e2ches distribu\u00e9es. Des tableaux de bord avanc\u00e9s ont \u00e9t\u00e9 ajout\u00e9s \u00e0 Grafana, permettant de surveiller les buckets, les appels API et les performances. Support ajout\u00e9 <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/fr\/ssl-sertifikat\/\"   title=\"des certificats TLS\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"982\">des certificats TLS<\/a> pour les composants admin et worker.\n<li class=\"l\"> Le m\u00e9canisme valuesFrom de FluxCD a remplac\u00e9 les fonctions de recherche dans les charts Helm. Cette am\u00e9lioration architecturale assure une transmission des param\u00e8tres plus propre et \u00e9limine la n\u00e9cessit\u00e9 de contr\u00f4leurs de synchronisation forc\u00e9e (reconciliation).
