O projeto visa fornecer uma plataforma pronta para provedores de hospedagem e um framework para constru\u00e7\u00e3o de nuvens privadas e p\u00fablicas. A plataforma \u00e9 instalada diretamente nos servidores e abrange todos os aspectos da prepara\u00e7\u00e3o da infraestrutura para a oferta de servi\u00e7os gerenciados. O Cozystack permite executar e fornecer clusters Kubernetes, bancos de dados e m\u00e1quinas virtuais. O c\u00f3digo da plataforma est\u00e1 dispon\u00edvel no GitHub e \u00e9 distribu\u00eddo sob a licen\u00e7a Apache-2.0.      <\/p>\n<p>Como stack tecnol\u00f3gico base, \u00e9 utilizado o Talos Linux e Flux CD. As imagens do sistema, do kernel e dos m\u00f3dulos necess\u00e1rios s\u00e3o pr\u00e9-formadas e atualizadas de forma at\u00f4mica, permitindo dispensar componentes como dkms e gerenciadores de pacotes, garantindo opera\u00e7\u00e3o est\u00e1vel. \u00c9 fornecido um m\u00e9todo simples de instala\u00e7\u00e3o em um data center vazio usando PXE e o instalador talos-bootstrap do tipo debian. Dentro da plataforma, \u00e9 poss\u00edvel implantar com um clique servi\u00e7os como Kafka, FerretDB, PostgreSQL, Cilium, Grafana, Victoria Metrics e outros.       <\/p>\n<p>A plataforma inclui uma implementa\u00e7\u00e3o livre <a href=\"https:\/\/prohoster.info\/pt\/server\/dts-sofia\/\"  data-wpil-monitor-id=\"403\">da infraestrutura de rede<\/a> (fabric) baseada em Kube-OVN, e utiliza Cilium para a organiza\u00e7\u00e3o da rede de servi\u00e7os, MetalLB para a divulga\u00e7\u00e3o de servi\u00e7os externamente. O armazenamento \u00e9 implementado no LINSTOR, onde o uso do ZFS como camada base para armazenamento e DRBD para replica\u00e7\u00e3o \u00e9 proposto. H\u00e1 uma pilha de monitoramento pr\u00e9-configurada baseada em VictoriaMetrics e Grafana.

Entre as mudan\u00e7as nessas vers\u00f5es est\u00e3o:   <\/p>\n<ul>\n<li class=\"l\"> A interface do usu\u00e1rio foi reescrita do zero. O projeto openapi-ui foi utilizado como base.    <center><img decoding=\"async\" alt=\"Lan\u00e7amento do Cozystack 0.37, uma plataforma PaaS open source baseada em Kubernetes\" src=\"\/wp-content\/uploads\/2025\/11\/e9f4b3d8fea5b49f04eba41eca15da7b.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> Foi adicionado um seletor de cluster \u00e0 interface. Agora o painel opera em modo de cluster \u00fanico (um painel por cluster). No futuro, essa mesma interface ser\u00e1 utilizada para o modo multicluster.\n<li class=\"l\">  Na tela do cluster, agora \u00e9 poss\u00edvel ver imediatamente todos os espa\u00e7os dispon\u00edveis dos namespaces. A lista \u00e9 formada atrav\u00e9s de uma camada agregadora do Kubernetes (tenant namespace), portanto, s\u00e3o mostrados apenas os espa\u00e7os aos quais se tem acesso.\n<li class=\"l\"> A cria\u00e7\u00e3o de recursos agora acontece atrav\u00e9s de formul\u00e1rios, gerados automaticamente a partir do OpenAPI do Kubernetes. Coment\u00e1rios em YAML n\u00e3o s\u00e3o necess\u00e1rios: os campos e a valida\u00e7\u00e3o s\u00e3o obtidos diretamente das especifica\u00e7\u00f5es.\n<li class=\"l\"> A especifica\u00e7\u00e3o de novos aplicativos \u00e9 formada a partir de Helm charts usando o gerador cozy-values, e os campos inseridos no formul\u00e1rio s\u00e3o refletidos sincronicamente no YAML final.\n<li class=\"l\"> Os m\u00f3dulos de gerenciamento de tenants foram realocados para a se\u00e7\u00e3o de administra\u00e7\u00e3o: aqui \u00e9 poss\u00edvel criar subtenants e colocar m\u00f3dulos\/aplicativos espec\u00edficos para eles (o acesso depende do papel e direitos do usu\u00e1rio).\n<li class=\"l\"> Est\u00e1 programada a adi\u00e7\u00e3o de uma aba com console VNC para m\u00e1quinas virtuais. Para alguns tipos de recursos, abas\/campos especiais ser\u00e3o adicionados (por exemplo, para KubeVirt-VM).\n<li class=\"l\"> O mecanismo de gerenciamento de recursos para tenants Cozystack foi estabilizado. Os administradores da plataforma agora podem definir limites expl\u00edcitos de CPU, mem\u00f3ria e armazenamento para cada namespace de tenant na especifica\u00e7\u00e3o do tenant. Assim, nenhum tenant pode \"consumir\" todos os recursos, deixando outros tenants sem recursos.\n<li class=\"l\"> Adicionado o componente Kube-OVN Plunger para monitoramento cont\u00ednuo do estado do cluster de gerenciamento central da rede Kube-OVN. Um agente externo coleta o status do cluster OVN e informa\u00e7\u00f5es sobre consenso, exibindo m\u00e9tricas do Prometheus e fluxo de eventos atrav\u00e9s do SSE (Server-Sent Events).\n<li class=\"l\"> O complemento CoreDNS agora \u00e9 implantado via Helm chart e configurado na especifica\u00e7\u00e3o do cluster (autoescalonamento, n\u00famero de r\u00e9plicas, IP do servi\u00e7o, etc.). O CoreDNS pode ser configurado tanto no painel quanto atrav\u00e9s da API Cozystack.\n<li class=\"l\"> O armazenamento S3 baseado em SeaweedFS se tornou mais flex\u00edvel em n\u00edvel de componentes. O Helm chart permite configurar independentemente cada componente e seus recursos: n\u00f3s mestres, servidores de volume (com suporte a v\u00e1rias zonas), banco de dados e gateway S3. Os administradores podem definir para cada componente o n\u00famero de r\u00e9plicas, limites de CPU\/mem\u00f3ria e volume de armazenamento.\n<li class=\"l\"> O FS SeaweedFS 3.97 foi integrado com suporte \u00e0 criptografia de servidores para buckets S3 (SSE-C, SSE-KMS, SSE-S3). Ao atualizar, a vers\u00e3o do SeaweedFS ser\u00e1 atualizada e a especifica\u00e7\u00e3o dos servi\u00e7os ser\u00e1 automaticamente convertida para o novo formato.\n<li class=\"l\"> O controlador NGINX agora \u00e9 configur\u00e1vel a n\u00edvel de cada r\u00e9plica: \u00e9 poss\u00edvel definir solicita\u00e7\u00f5es\/lindites de CPU e mem\u00f3ria diretamente ou escolher uma das predefini\u00e7\u00f5es dispon\u00edveis.\n<li class=\"l\"> Se uma m\u00e1quina virtual tiver um IP externo atribu\u00eddo, ele ser\u00e1 sempre utilizado para tr\u00e1fego egress, independentemente do m\u00e9todo de atribui\u00e7\u00e3o desse IP.  <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64178\">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 0.37, \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.
