Projektet sigter mod at levere en klar platform for hostingudbydere samt et framework til opbygning af private og offentlige skyder. Platformen installeres direkte p\u00e5 servere og d\u00e6kker alle aspekter af infrastrukturen til levering af styrede tjenester. Cozystack muligg\u00f8r implementering og levering af Kubernetes-clustre, databaser og virtuelle maskiner. Kildekoden til platformen er tilg\u00e6ngelig p\u00e5 GitHub og distribueres under Apache-2.0-licensen.      <\/p>\n<p>Talos Linux og Flux CD bruges som den grundl\u00e6ggende teknologiske stak. Billederne med systemet, kernen og n\u00f8dvendige moduler dannes p\u00e5 forh\u00e5nd og opdateres atomart, hvilket g\u00f8r det muligt at undg\u00e5 komponenter som dkms og pakkeh\u00e5ndteringssystemet og sikrer stabil drift. Der tilbydes en enkel installationsmetode i et tomt datacenter ved hj\u00e6lp af PXE og en debian-lignende installationsprogram talos-bootstrap.       <\/p>\n<p>Platformen inkluderer en fri implementering <a href=\"https:\/\/prohoster.info\/da\/server\/dts-sofia\/\"  data-wpil-monitor-id=\"3245\">af netv\u00e6rksinfrastruktur<\/a> (fabric) baseret p\u00e5 Kube-OVN, og bruger Cilium til at organisere tjenestenetv\u00e6rket, MetalLB til at annoncere tjenester til omverdenen. Lagring er implementeret p\u00e5 LINSTOR, hvor ZFS tilbydes som basislag for lagring og DRBD til replikering. Der er en forudindstillet monitoreringsstak baseret p\u00e5 VictoriaMetrics og Grafana. Til opstart <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/vps\/\"   title=\"virtual machines\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2141\">virtual machines<\/a> KubeVirt-teknologien bruges, som muligg\u00f8r k\u00f8rsel af traditionelle virtuelle maskiner direkte i Kubernetes-containere og allerede har alle n\u00f8dvendige integrationer med Cluster API til at k\u00f8re administrerede Kubernetes-klynger inden i et &#171;jern&#187; Kubernetes-klynge.    <\/p>\n<p>I den nye version er dashboardets interface helt omarbejdet, og det arbejder nu direkte med Cozystack API'et i stedet for med FluxCD-ressourcer. \u00c6ndringen giver slutbrugerne et grafisk interface og muligg\u00f8r tildeling af rettigheder til at implementere forskellige tjenester under hensyntagen til den standardiserede RBAC-model i Kubernetes. Der oprettes som standard fire grupper for hver tenant:  <\/p>\n<ul>\n<li class=\"l\"> visning \u2014 kun til readonly adgang;\n<li class=\"l\"> brug \u2014 til forbindelse til virtuelle maskiner og brug af tjenester;\n<li class=\"l\"> admin \u2014 for at bestille grundl\u00e6ggende tjenester (mysql, postgres, redis, kubernetes, virtual-machine osv.);\n<li class=\"l\"> super-admin \u2014 for oprettelse af underliggende tenant- og opstart af tjenesteydelser (monitoring, etcd, ingress og seaweedfs).  <\/ul>\n<p>Brugere, der er inkluderet i de relevante grupper, kan f\u00e5 adgang b\u00e5de via Kubernetes og via dashboardet. Selvom Cozystack bruger en API-orienteret tilgang, er dashboardet en vigtig del af platformen, da det muligg\u00f8r hurtig oprettelse af n\u00f8dvendige tjenester via det grafiske interface, hvorefter man kan se, hvordan de vises i API'et, og derefter beskrive dem som kode (IaC).    <\/p>\n<p>Hovedm\u00e5linger i dashboardet:  <\/p>\n<ul>\n<li class=\"l\"> Direkte adgang til Cozystack API'et er sikret.\n<li class=\"l\"> Pr\u00e6fikserne for applikationer er fjernet, da hver applikation nu bruger sin egen Kind.\n<li class=\"l\"> Navnerum filtreres efter pr\u00e6fiks \u00abtenant-\u00ab, hvilket tillader visning af kun brugernavnede navnerum og udelukker systemnavnerum fra visningen.\n<li class=\"l\"> Ikonerne vises korrekt ved aktivering af OIDC (OpenID Connect).\n<li class=\"l\"> Tilf\u00f8jet kosmetiske forbedringer, herunder korrekte links til dokumentationen.  <\/ul>\n<p>Andre \u00e6ndringer:   <\/p>\n<ul>\n<li class=\"l\"> Tilladelse til Redis er blevet tilf\u00f8jet.\n<li class=\"l\"> Rolle- og rollebindinger til tenants er blevet refaktoreret, alle tilladelser for HelmRelease-ressourcer er blevet fjernet, og gruppen kubeapps-admin er blevet slettet.\n<li class=\"l\"> Fejlen i opstartningen af Grafana er rettet, og URL'en til VictoriaLogs plugin'et er blevet korrigeret.\n<li class=\"l\"> OpenAPI-specifikationen for List-ressourcer i API Cozystack er blevet rettet.\n<li class=\"l\"> Talos Linux er opdateret til version 1.8.4.\n<li class=\"l\"> Linstor-ha-controller er opdateret til version 1.2.3, hvilket har l\u00f8st problemet med h\u00f8j tilg\u00e6ngelighed for virtuelle maskiner.\n<li class=\"l\"> Der er tilf\u00f8jet en indstilling for st\u00f8rrelse til Grafana-databasen.\n<li class=\"l\"> Yderligere muligheder for ressourceh\u00e5ndtering er blevet tilf\u00f8jet til VMCluster.  <\/ul>\n<p>Kilde: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=62482\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0414\u043e\u0441\u0442\u0443\u043f\u0435\u043d \u0432\u044b\u043f\u0443\u0441\u043a \u0441\u0432\u043e\u0431\u043e\u0434\u043d\u043e\u0439 PaaS-\u043f\u043b\u0430\u0442\u0444\u043e\u0440\u043c\u044b Cozystack 0.21.0, \u043f\u043e\u0441\u0442\u0440\u043e\u0435\u043d\u043d\u043e\u0439 \u043d\u0430 \u0431\u0430\u0437\u0435 Kubernetes. \u041f\u0440\u043e\u0435\u043a\u0442 \u043d\u0430\u0446\u0435\u043b\u0435\u043d \u043d\u0430 \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u0435\u043d\u0438\u0435 \u0433\u043e\u0442\u043e\u0432\u043e\u0439 \u043f\u043b\u0430\u0442\u0444\u043e\u0440\u043c\u044b \u0434\u043b\u044f \u0445\u043e\u0441\u0442\u0438\u043d\u0433-\u043f\u0440\u043e\u0432\u0430\u0439\u0434\u0435\u0440\u043e\u0432 \u0438 \u0444\u0440\u0435\u0439\u043c\u0432\u043e\u0440\u043a\u0430 \u0434\u043b\u044f \u043f\u043e\u0441\u0442\u0440\u043e\u0435\u043d\u0438\u044f \u0447\u0430\u0441\u0442\u043d\u044b\u0445 \u0438 \u043f\u0443\u0431\u043b\u0438\u0447\u043d\u044b\u0445 \u043e\u0431\u043b\u0430\u043a\u043e\u0432. \u041f\u043b\u0430\u0442\u0444\u043e\u0440\u043c\u0430 \u0443\u0441\u0442\u0430\u043d\u0430\u0432\u043b\u0438\u0432\u0430\u0435\u0442\u0441\u044f \u043d\u0430\u043f\u0440\u044f\u043c\u0443\u044e \u043d\u0430 \u0441\u0435\u0440\u0432\u0435\u0440\u044b \u0438 \u043e\u0445\u0432\u0430\u0442\u044b\u0432\u0430\u0435\u0442 \u0432\u0441\u0435 \u0430\u0441\u043f\u0435\u043a\u0442\u044b \u043f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u043a\u0438 \u0438\u043d\u0444\u0440\u0430\u0441\u0442\u0440\u0443\u043a\u0442\u0443\u0440\u044b \u0434\u043b\u044f \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u0435\u043d\u0438\u044f \u0443\u043f\u0440\u0430\u0432\u043b\u044f\u0435\u043c\u044b\u0445 \u0441\u0435\u0440\u0432\u0438\u0441\u043e\u0432.
