O projeto visa oferecer uma plataforma pronta para provedores de hospedagem e um framework para a 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. 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 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=\"401\">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>No novo lan\u00e7amento:  <\/p>\n<ul>\n<li class=\"l\"> Adicionado o planejador LINSTOR para aloca\u00e7\u00e3o ideal de pods. O pr\u00f3prio 'scheduler extender' para Kubernetes funciona juntamente com o planejador padr\u00e3o do Kubernetes e ajuda a alocar os pods de forma otimizada em n\u00f3s com armazenamento LINSTOR. Quando um pod solicita um volume LINSTOR, o planejador consulta o controlador LINSTOR para saber em quais n\u00f3s existem r\u00e9plicas locais dos volumes solicitados. A prioridade \u00e9 dada aos n\u00f3s onde os dados j\u00e1 est\u00e3o presentes, minimizando o tr\u00e1fego de rede e aumentando o desempenho de I\/O. Adicionalmente, foi implementado um admission webhook que direciona automaticamente os pods que utilizam volumes CSI do LINSTOR para o seu pr\u00f3prio planejador, garantindo uma integra\u00e7\u00e3o sem costura e sem necessidade de configura\u00e7\u00e3o manual.\n<li class=\"l\"> Armazenamento SeaweedFS SeaweedFS foi atualizado para a vers\u00e3o 4.05, na qual foi otimizado o tr\u00e1fego S3 (localidade de tr\u00e1fego): agora, as solicita\u00e7\u00f5es s\u00e3o direcionadas para os servidores mais pr\u00f3ximos, reduzindo a lat\u00eancia e acelerando o funcionamento do armazenamento. Tamb\u00e9m foi adicionado um novo componente de administra\u00e7\u00e3o com interface web e suporte a autoriza\u00e7\u00e3o, al\u00e9m de workers para executar tarefas distribu\u00eddas. No Grafana, foram adicionados dashboards avan\u00e7ados, permitindo o monitoramento de buckets, chamadas de API e performance. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/ssl-sertifikat\/\"   title=\"certificados TLS\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"982\">certificados TLS<\/a> para os componentes de administra\u00e7\u00e3o e worker.\n<li class=\"l\"> O mecanismo valuesFrom do FluxCD substituiu as fun\u00e7\u00f5es de lookup nos gr\u00e1ficos Helm. Essa melhoria arquitetural proporciona uma transmiss\u00e3o de par\u00e2metros mais limpa e elimina a necessidade de controladores de sincroniza\u00e7\u00e3o for\u00e7ada (reconciliation). A configura\u00e7\u00e3o a partir de ConfigMaps e refer\u00eancias a servi\u00e7os agora \u00e9 gerenciada centralmente atrav\u00e9s da chave cozystack-values em cada namespace.\n<li class=\"l\"> Nos componentes para integra\u00e7\u00e3o com LINSTOR, foi implementado suporte \u00e0 fun\u00e7\u00e3o auto-diskful, que transforma n\u00f3s sem disco (diskless) em n\u00f3s com disco (diskful) se estes mantiverem recursos DRBD no estado Prim\u00e1rio por mais de 30 minutos.\n<li class=\"l\"> Implementados sistemas de gerenciamento autom\u00e1tico de vers\u00f5es para PostgreSQL, Kubernetes, MariaDB e Redis, que monitoram atualiza\u00e7\u00f5es nos reposit\u00f3rios upstream e fornecem mecanismos para atualiza\u00e7\u00e3o autom\u00e1tica de vers\u00f5es.  <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64640\">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 0.40, \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.
