O projeto visa fornecer uma plataforma pronta para provedores de hospedagem e um framework para construir nuvens privadas e p\u00fablicas. A plataforma \u00e9 instalada diretamente em servidores e abrange todos os aspectos da prepara\u00e7\u00e3o da infraestrutura para a oferta de servi\u00e7os gerenciados. O Cozystack permite iniciar 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 de tecnologia b\u00e1sica, utiliza-se Talos Linux e Flux CD. As imagens com o sistema, kernel e m\u00f3dulos necess\u00e1rios s\u00e3o pr\u00e9-formadas e atualizadas de forma at\u00f4mica, o que permite a dispensa de componentes como dkms e gerenciadores de pacotes, garantindo um funcionamento est\u00e1vel. Um m\u00e9todo simples de instala\u00e7\u00e3o em um data center vazio \u00e9 proporcionado atrav\u00e9s de PXE e um instalador semelhante ao Debian chamado talos-bootstrap.       <\/p>\n<p>A plataforma inclui uma implementa\u00e7\u00e3o livre <a href=\"https:\/\/prohoster.info\/pt\/server\/dts-sofia\/\"  data-wpil-monitor-id=\"406\">da infraestrutura de rede<\/a> (fabric) baseado em Kube-OVN, utilizando Cilium para 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 \u00e9 oferecido como camada base de armazenamento e do DRBD para replica\u00e7\u00e3o. H\u00e1 uma pilha de monitoramento pr\u00e9-configurada baseada em VictoriaMetrics e Grafana. Para o lan\u00e7amento de m\u00e1quinas virtuais, utiliza-se a tecnologia KubeVirt, que permite rodar m\u00e1quinas virtuais cl\u00e1ssicas diretamente nos cont\u00eaineres do Kubernetes e j\u00e1 possui todas as integra\u00e7\u00f5es necess\u00e1rias com o Cluster API para o lan\u00e7amento de clusters Kubernetes gerenciados dentro do cluster Kubernetes 'f\u00edsico'.    <\/p>\n<p>Nos \u00faltimos um ano e meio, a equipe do projeto lan\u00e7ou sete novas vers\u00f5es: 0.24-0.30. Entre as mudan\u00e7as nestas vers\u00f5es est\u00e3o:    <\/p>\n<ul>\n<li class=\"l\"> Estabiliza\u00e7\u00e3o da plataforma para uso em configura\u00e7\u00f5es multi-DC. Foi feito um grande trabalho de ajuste no etcd, Cilium, Kuve-OVN, Linstor e outros componentes.\n<li class=\"l\"> Fortalecimento e aprimoramento da pilha de observabilidade. Foram adicionados pain\u00e9is de controle para v\u00e1rios componentes e as configura\u00e7\u00f5es do Grafana foram otimizadas, acelerando seu desempenho.\n<li> Lan\u00e7amento de uma ferramenta adicional, cozy-proxy, que permite emitir <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/lir\/ipv4\/\"   title=\"endere\u00e7os IP\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"726\">endere\u00e7os IP<\/a> m\u00e1quinas virtuais em K8s.\n<li class=\"l\"> Apari\u00e7\u00e3o do Vertical Pod Autoscaler. O VPA define automaticamente os limites de recursos que uma aplica\u00e7\u00e3o pode consumir. Os limites s\u00e3o determinados com base em m\u00e9tricas hist\u00f3ricas.\n<li class=\"l\"> Refatora\u00e7\u00e3o e adi\u00e7\u00e3o de novas se\u00e7\u00f5es na documenta\u00e7\u00e3o.\n<li class=\"l\"> Mudan\u00e7a do reposit\u00f3rio da plataforma e ferramentas auxiliares da organiza\u00e7\u00e3o aenix-io para a organiza\u00e7\u00e3o cozystack ap\u00f3s a transfer\u00eancia do projeto para o CNCF Sandbox.\n<li class=\"l\">  Cozystack 0.30: Apresentado o GPU-operator e adicionada a suporte a GPU em m\u00e1quinas virtuais. O suporte a GPU permite usar a plataforma para executar tarefas relacionadas ao aprendizado de m\u00e1quina.\n<li class=\"l\">  Cozystack 0.29: Trabalhos realizados para aumentar a estabilidade e confiabilidade da plataforma. Vulnerabilidade CVE-2025-1974 no ingress-nginx corrigida. Conjunto de presets adicionado para limitar o consumo de recursos. Implementa\u00e7\u00e3o da renova\u00e7\u00e3o autom\u00e1tica de certificados. Adicionado firewall host Cilium. Adicionado processo para executar testes e2e no GitHub CI.\n<li class=\"l\">  Cozystack 0.28: Aparecimento do Vertical Pod Autoscaler, que define automaticamente os limites de recursos dispon\u00edveis para diferentes aplica\u00e7\u00f5es. A isola\u00e7\u00e3o de tenants \u00e9 habilitada por padr\u00e3o. A responsabilidade pela valida\u00e7\u00e3o do source-ip foi transferida do Cilium para o Kube-OVN.\n<li class=\"l\">  Cozystack 0.27: Um conjunto de scripts linstor plunger foi proposto para corrigir automaticamente erros no LINSTOR (por exemplo, conex\u00e3o perdida do DRBD, dispositivo loop travado, etc.). Foi adicionada a possibilidade de distribuir r\u00e9plicas do PostgreSQL entre diferentes n\u00f3s. Foram criados dashboards para monitoramento do ClickHouse e Piraeus.\n<li class=\"l\"> Cozystack 0.26: A estabilidade foi melhorada ao trabalhar em configura\u00e7\u00f5es multidata center. Foi adicionado o monitoramento da conectividade de rede. Agora \u00e9 poss\u00edvel limitar recursos para inquilinos espec\u00edficos dentro do cluster. O Goldpinger foi adicionado como ferramenta para monitorar lat\u00eancias entre data centers. A migra\u00e7\u00e3o ao vivo de m\u00e1quinas virtuais foi habilitada por padr\u00e3o. A possibilidade de criar snapshots de volumes LINSTOR foi introduzida.\n<li class=\"l\"> Cozystack 0.25: Ferramenta auxiliar cozy-proxy adicionada, que permite a atribui\u00e7\u00e3o de endere\u00e7os IP inteiros para m\u00e1quinas virtuais \u2014 e n\u00e3o apenas portas individuais. No Cosyastack, as m\u00e1quinas virtuais s\u00e3o baseadas em KubeVirt e gerenciadas de maneira semelhante aos pods. O Kubernetes n\u00e3o prev\u00ea a atribui\u00e7\u00e3o de endere\u00e7os IP inteiros para os pods. O cozy-proxy resolve esse problema, o que \u00e9 importante, por exemplo, para clientes de provedores de servi\u00e7os cujos aplicativos rodam em m\u00e1quinas virtuais e que necessitam de um endere\u00e7o IP separado. O monitoramento do etcd, Flux, Kafka foi aprimorado e os dashboards correspondentes foram adicionados. Agora, usu\u00e1rios que t\u00eam acesso apenas a tenant espec\u00edficos podem baixar o kubeconfig.\n<li class=\"l\"> Cozystack 0.24: Adicionada a possibilidade de implanta\u00e7\u00e3o via PXE, para carregar automaticamente o Talos Linux nos n\u00f3s. O pacote smee (servidor dhcp+pxe) do conjunto Tinkerbell foi inclu\u00eddo. O Darkhttp foi substitu\u00eddo por uma solu\u00e7\u00e3o desenvolvida internamente, o cozystack-assets-server. Plugins foram integrados na imagem do Grafana para que ele inicie mais rapidamente.      <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=63047\">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 0.30.0, \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.
